,,the ,,ocean ,,and ,,its ,,wonders1 ,,by ,r4,m4 ,,ballantyne4 ,,chapter ,,one4 ,,what ,,the ,,ocean ,,has ,,to ,,say--,,its ,,whispers--,,its ,,thunders--,,its ,,secrets4 ,there is a voice in the waters of the great sea4 ,it calls to man continually4 ,sometimes it thunders in the tempest1 when the waves leap high and strong and the wild winds shriek and roar1 as if to force our attention4 ,sometimes it whispers in the calm1 and comes rippling on the shingly beach in a still1 small voice1 as if to solicit our regard4 ,but whether that voice of ocean comes in crashing billows or in gentle murmurs1 it has but one tale to tell1--it speaks of the love1 and power1 and majesty of ,him who rides upon the storm1 and rules the wave4 ,yes1 the voice of ocean tells but one tale2 yet there are many chapters in that wonderful story4 ,the sea has much to say2 far more than could possibly be comprehended in one volume1 however large4 ,it tells us of the doings of man on its broad bosom1 from the day in which he first ventured to paddle along shore in the hollow trunk of a tree1 to the day when he launched his great iron ship of #bj1jjj tons1 and rushed out to sea1 against wind and tide1 under an impulse equal to the united strength of #aa1ejj horses4 ,no small portion of the ocean's tale this1 comprising many chapters of deeds of daring1 blood1 villainy1 heroism1 and enterprise4 ,but with this portion of its story we have nothing to do just now4 ,it tells us1 also1 of ,god's myriad and multiform creatures1 that dwell in its depths1 from the vast whale1 whose speed is so great1 that it might1 if it chose1 circle round the world in a few days1 to the languid zoophyte1 which clings to the rock1 and bears more resemblance to a plant than to a living animal4 ,the sea has secrets1 too1 some of which it will not divulge until that day when its ,creator shall command it to give up its dead2 while others it is willing to part with to those who question it closely1 patiently1 and with intelligence4 ,among the former kind of secrets are those foul deeds that have been perpetrated1 in all ages1 by abandoned men2 when no human ears listened to the stifled shriek1 or the gurgling plunge2 when no human eyes beheld the murderous acts1 the bloody decks1 the blazing vessels1 or the final hiss of the sinking wrecks4 ,among the latter kind of secrets are the lives and habits of the creatures of the deep1 and the causes and effects of those singular currents of air and water1 which1 to the eye of ignorance1 seem to be nothing better than irregularity and confusion2 but which1 to the minds of those who search them out1 and have pleasure therein1 are recognised as a part of that wonderful1 orderly1 and systematic arrangement of things that we call ,nature3 much of which we now know1 more of which we shall certainly know1 as each day and year adds its quota to the sum of human knowledge2 but a great deal of which will1 doubtless1 remain for ever hidden in the mind of nature's ,god1 whose ways are wonderful1 and past finding out4 ,it is the latter class of secrets to which we purpose directing the readers attention in the following pages4 ,on approaching so vast a subject1 we feel like the traveller who1 finding himself suddenly transported into the midst of a new and magnificent region1 stands undecided whither to direct his steps in the endlessly varied scene4 ,or1 still more1 like the visitor to our great ,international ,exhibition of #ahfb1 who1--entering abruptly that gigantic palace1 where were represented the talent1 the ingenuity1 time wealth1 and industry of every people and clime1--attempts1 in vain1 to systematise his explorations1 or to fix his attention4 ,it is probable that1 in each of these supposed cases1 the traveller and visitor1 resigning the desire to achieve what is impossible1 would give themselves up to the agreeable guidance of a wandering and wayward fancy4 ,let us1 reader1 act in a somewhat similar manner4 ,let us touch here1 and there1 and everywhere1 on the wonders of the sea1 and listen to such notes of the ,ocean's ,voice as strike upon our ears most pleasantly4 ,,chapter ,,two4

,,apparatus--,,importance ,,of ,,the ,,search ,,after ,,truth--,,illustrations-- ,,discoveries ,,resulting ,,from ,,deep-,,sea ,,soundings4 ,before proceeding to the consideration of the wonders connected with and contained in the sea1 we shall treat of the composition of the sea itself and of its extent1 depth1 and bottom4 ,what is the sea made of8 ,salt water1 is the ready reply that rises naturally to every lip4 ,but to this we add the question1--,what is salt water8 or1 as there are many kinds of salt water1 of what sort of salt water does the sea consist8 ,to these queries we give the following reply1 which1 we doubt not1 will rather surprise some of our readers4 ,fresh water1 as most people are aware1 is composed of two gases--oxygen and hydrogen4 ,sea water is composed of the same gases1 with the addition of muriate of soda1 magnesia1 iron1 lime1 sulphur1 copper1 silex1 potash1 chlorine1 iodine1 bromine1 ammonia1 and silver4 ,what a dose6 ,let bathers think of it next time they swallow a gulp of sea water4 ,most of these substances1 however1 exist in comparatively small quantity in the sea1 with the exception of muriate of soda1 or common table salt2 of which1 as all bathers know from bitter experience1 there is a very considerable quantity4 ,the quantity of silver contained in sea water is very small indeed4 ,nevertheless1 small though it be1 the ocean is so immense1 that1 it has been calculated1 if all the silver in it were collected1 it would form a mass that would weigh about two hundred million tons6 ,the salt of the ocean varies considerably in different parts4 ,near the equator1 the great heat carries up a larger proportion of water by evaporation than in the more temperate regions2 and thus1 as salt is not removed by evaporation1 the ocean in the torrid zone is salter than in the temperate or frigid zones4 ,the salts of the sea1 and other substances contained in it1 are conveyed thither by the fresh-water streams that pour into it from all the continent of the world4 ,maury1 in his delightful work1 ,the ,physical ,geography of the ,sea1 tells us that water is ,nature's great carrier4 ,with its currents it conveys heat away from the torrid zone1 and ice from the frigid2 or1 bottling the caloric away in the vesicle of its vapour1 it first makes it impalpable1 and then conveys it by unknown paths to the most distant parts of the ,earth4 ,the materials of which the coral builds the island1 and the sea-conch its shell1 are gathered by this restless leveller from mountains1 rocks1 and valleys1 in all latitudes4 ,some it washes down from the ,mountains of the ,moon in ,africa1 or out of the gold-fields of ,australia1 or from the mines of ,potosi2 others from the battle-fields of ,europe1 or from the marble quarries of ancient ,greece and ,rome4 ,the materials thus collected1 and carried over falls and down rapids1 are transported to the sea4 ,here1 as these substances cannot be evaporated1 they would accumulate to such a degree as to render the ocean uninhabitable by living creatures1 had not ,god provided against this by the most beautiful compensation4 ,he has filled the ocean with innumerable animals and marine plants1 whose special duty it is to seize and make use of the substances thus swept from the land1 and reconvert them into solids4 ,we cannot form an adequate conception of the extent of the great work carried on continually in this way2 but we see part of it in the chalk cliffs1 the marl beds of the sea shore1 and the coral islands of the ,south ,seas1--of which last more particular notice shall be taken in a succeeding chapter4 ,the operations of the ocean are manifold4 ,besides forming a great reservoir1 into which what may be termed the impurities of the land are conveyed1 it is1 as has been shown1 the great laboratory of ,nature1 where these are reconverted1 and the general balance restored4 ,but we cannot speak of these things without making passing reference to the operations of water1 as that wonder-working agent of which the ocean constitutes but a part4 ,nothing in this world is ever lost or annihilated4 ,as the ocean receives all the water that flows from the land1 so it returns that water1 fresh and pure1 in the shape of vapour1 to the skies2 where1 in the form of clouds1 it is conveyed to those parts of the earth where its presence is most needed1 and precipitated in the form of rain and dew1 fertilising the soil1 replenishing rivers and lakes1 penetrating the earth's deep caverns2 whence it bubbles up in the shape of springs1 and1 after having gladdened the heart of man by driving his mills and causing his food to grow1 it finds its way again into the sea3 and thus the good work goes on with ceaseless regularity4 ,water beats upon the rocks of the sea-shore until it pounds them into sand1 or rolls them into pebbles and boulders4 ,it also sweeps the rich soil from the mountains into the valleys4 ,in the form of snow it clothes the surface of the temperate and frigid zones with a warm mantle1 which preserves vegetable life from the killing frosts of winter4 ,in the form of ice it splits asunder the granite hills2 and in the northern regions it forms great glaciers1 or masses of solidified snow1 many miles in extent1 and many hundred feet thick4 ,these glaciers descend by slow1 imperceptible degrees1 to the sea2 their edges break off and fall into it1 and1 floating southward1 sometimes in great mountainous masses1 are seen by man in the shape of icebergs4 ,frequently huge rocks1 that have fallen upon these glaciers from cliffs in the arctic regions1 are carried by them to other regions1 and are deposited on flat beaches1 far from their native cliffs4 ,the saltness of the sea rendering it more dense1 necessarily renders it more buoyant1 than fresh water4 ,this is obviously a great advantage to man in the matter of commerce4 ,a ship does not sink so deep in the sea as it does in a fresh-water lake2 hence it can carry more cargo with greater facility4 ,it is easier to swim in salt than in fresh water4 ,the only disadvantage to commerce in the saltness of the sea is the consequent unfitness of its water for drinking4 ,many and harrowing are the accounts of instances in which sailors have been reduced to the most terrible extremities for want of fresh water2 and many a time1 since navigation began1 have men been brought to feel the dread reality of that condition which is so forcibly expressed in the poem of the ,ancient ,mariner3-- ,water1 water everywhere1 ,and not a drop to drink4 ,science1 however1 at length enabled us to overcome this disadvantage of saltness4 ,by the process of distillation1 men soon managed to procure enough water at least to save their lives4 ,one captain of a ship1 by accident1 lost all his fresh water2 and1 before he could put into port to replenish1 a gale of wind1 which lasted three weeks1 drove him far out to sea4 ,he had no distilling apparatus on board1 and it seemed as if all hope of the crew escaping the most horrible of deaths were utterly taken away4 ,in this extremity the captain's inventive genius came to his aid4 ,he happened to have on board an old iron pitch-pot1 with a wooden cover4 ,using this as a boiler1 a pipe made of a pewter plate1 and a wooden cask as a receiver1 he set to work1 filled the pot with sea water1 put an ounce of soap therein to assist in purifying it1 and placed it on the fire4 ,when the pot began to boil1 the steam passed through the pipe into the cask1 where it was condensed into water1 minus the saline particles1 which1 not being evaporable1 were left behind in the pitch-pot4 ,in less than an hour a quart of fresh water was thus obtained2 which1 though not very palatable1 was sufficiently good to relieve the thirst of the ship's crew4 ,many ships are now regularly supplied with apparatus for distilling sea water2 and on the ,african coasts and other unhealthy stations1 where water is bad1 the men of our navy drink no other water than that which is distilled from the sea4 ,the salts of the ocean have something to do with the creating of oceanic currents2 which1 in their turn1 have a powerful influence on climates4 ,they also retard evaporation to some extent1 and have some effect in giving to the sea its beautiful blue colour4 ,the ocean covers about two-thirds of the entire surface of the ,earth4 ,its depth has never been certainly ascertained2 but from the numberless experiments and attempts that have been made1 we are warranted in coming to the conclusion that it nowhere exceeds five miles in depth1 probably does not quite equal that4 ,professor ,wyville ,thompson estimates the average depth of the sea at about two miles4 ,of the three great oceans into which the sea is naturally divided--the ,atlantic1 the ,pacific1 and the ,arctic--the ,atlantic is supposed to be the deepest4 ,there are profundities in its bosom which have never yet been sounded1 and probably never will be4 ,the difficulty of sounding great depths arises from the fact that1 after a large quantity of line has been run out1 the shock of the lead striking the bottom cannot be felt4 ,moreover1 there is sufficient force in the deep-sea currents to sweep out the line after the lead has reached the bottom so that1 with the ordinary sounding-lines in use among navigators1 it is impossible to sound great depths4 ,scientific men have1 therefore1 taxed their brains to invent instruments for sounding the deep sea--for touching the bottom in what sailors call blue water4 ,some have tried it with a silk thread as a plumb-line1 some with spun-yarn threads1 and various other materials and contrivances4 ,it has even been tried by exploding petards and ringing bells in the deep sea1 when it was supposed that an echo or reverberation might be heard1 and1 from the known rate at which sound travels through water1 the depth might thus be ascertained4 ,deep-sea leads have been constructed having a column of air in them1 which1 by compression1 would show the aqueous pressure to which they had been subjected2 but the trial proved to be more than the instrument could stand4 ,captain ,maury1 of the ,american ,navy--whose interesting book has been already referred to--invented an instrument for sounding the deep sea4 ,here is his own description of it3--,to the lead was attached1 upon the principle of the screw-propeller1 a small piece of clock-work for registering the number of revolutions made by the little screw during the descent2 and it having been ascertained by experiment in shoal water that the apparatus1 in descending1 would cause the propeller to make one revolution for every fathom of perpendicular descent1 hands provided with the power of self-registering were attached to a dial1 and the instrument was complete4 ,it worked beautifully in moderate depths1 but failed in blue water1 from the difficulty of hauling it up if the line used were small1 and from the difficulty of getting it down if the line used were large enough to give the requisite strength for hauling it up4 ,one eccentric old sea captain proposed to sound the sea with a torpedo1 or shell1 which should explode the instant it touched the bottom4 ,another gentleman proposed to try it by the magnetic telegraph1 and designed an instrument which should telegraph to the expectant measurers above how it was getting on in the depths below4 ,but all these ingenious devices failed1 and it is probable that the deepest parts of the ocean-bed still remained untouched by man4 ,at last an extremely simple and remarkably successful deep-sea sounding apparatus was invented by ,mr ,brooke1 an ,american officer4 ,it consisted of nothing more than thin twine for a sounding-line1 and a cannon ball for a sinker4 ,the twine was made for the purpose1 fine but very strong1 and was wound on a reel to the extent of ten thousand fathoms4 ,the cannon ball1 which was from thirty-two to sixty-eight pounds' weight1 had a hole quite through it1 into which was fixed a sliding rod1 the end of which1 covered with grease1 projected several inches beyond the ball4 ,by an ingenious and simple contrivance1 the cannon ball was detached when it reached the bottom of the sea1 and the light rod was drawn up with specimens of the bottom adhering to the grease4 ,with this instrument the ,americans went to work with characteristic energy1 and1 by always using a line of the same size and make1 and a sinker of the same shape and weight1 they at last ascertained the law of descent4 ,this was an important achievement1 because1 having become familiar with the precise rate of descent at all depths1 they were enabled to tell very nearly when the ball ceased to carry out the line1 and when it began to go out in obedience to the influence of deep-sea currents4 ,the greatest depth reached by ,brooke's sounding-line is said to have been a little under five miles in the ,north ,atlantic4 ,the value of investigations of this kind does not appear at first sight1 to unscientific men4 ,but those who have paid even a little attention to the methods and processes by which grand discoveries have been made1 and useful inventions have been perfected1 can scarcely have failed to come to the conclusion that the search after ,,truth1 pure and simple1 of any kind1 and of every kind1 either with or without reference to a particular end1 is one of the most useful as well as elevating pursuits in which man can engage4 ,all truth is worth knowing and labouring after4 ,no one can tell to what useful results the discovery of even the smallest portion of truth may lead4 ,some of the most serviceable and remarkable inventions of modern times have been the result of discoveries of truths which at first seemed to have no bearing whatever on those inventions4 ,when ,james ,watt sat with busy reflective mind staring at a boiling kettle1 and discovered the expansive power of steam1 no one could have for a moment imagined that in the course of years the inventions founded on the truth then discovered would result in the systematic driving of a fleet of floating palaces all round the world at the rate of from twelve to fifteen or twenty miles an hour6 ,instances of a similar kind might be multiplied without end4 ,in like manner1 deep-sea sounding may lead to great1 as yet unimagined1 results4 ,although yet in its infancy1 it has already resulted in the discovery of a comparatively shallow plateau or ridge in the ,north ,atlantic ,ocean1 rising between ,ireland and ,newfoundland2 a discovery which has been turned to practical account1 inasmuch as the plateau has been chosen to be the bed of our electric telegraph between ,europe and ,america4 ,the first ,atlantic cable was laid on it2 and although that cable suffered many vicissitudes at first1 as most contrivances do in their beginnings1 communication between the two continents was successfully established4 ,soundings taken elsewhere showed that somewhat similar plateaus existed in other parts of the ,atlantic1 and now the whole of ,western ,europe is being bound more firmly1 by additional cables1 to the eastern seaboard of ,america4 ,this great and glorious achievement has been the result of the discovery of two truths1--of a truth in science on the one hand1 and a truth in regard to the structure of the bed of the sea on the other4 ,the study of electricity and of deep-sea soundings was begun and carried on for the sake of the discovery of truth alone1 and without the most distant reference to the ,atlantic ,telegraph1--yet that telegraph has been one of the results of that study4 ,who can tell how many more shall follow8 ,and even were no other result ever to follow1 this one may prove to be of the most stupendous importance to the human race4 ,another discovery that has been made by deep-sea sounding is1 that the lowest depths of the ocean are always in a state of profound calm4 ,oceanic storms do not extend to the bottom4 ,when the tempest is lashing the surface of the sea into a state of the most violent and tremendous agitation1 the caverns of the deep are wrapped in perfect repose4 ,this has been ascertained from the fact that in many places the bottom of the sea1 as shown by the specimens brought up by ,brooke's apparatus1 and more recently by ,professor ,thompson's deep-sea dredge1 is composed of exceedingly minute shells of marine insects4 ,these shells1 when examined by the microscope1 are found to be unbroken and perfect1 though so fragile that they must certainly have been broken to pieces had they ever been subjected to the influence of currents1 or to the pulverising violence of waves4 ,hence the conclusion that the bottom of the sea is in a state of perpetual rest and placidity4 ,indeed1 when we think of it1 we are led to conclude that this must necessarily be the case4 ,there are1 as we shall presently show1 currents of vast size and enormous power constantly flowing through the ocean2 and when we think of the tremendous power of running water to cut through the solid rock1 as exemplified in the case of ,niagara1 and many other rivers1 what would be the result of the action of currents in the sea1 compared with which ,niagara is but a tiny rivulet8 ,ocean currents1 then1 flow on a bed of still water1 that protects the bottom of the sea from forces which1 by calculation1 we know would long ago have torn up the foundations of the deep1 and would probably have destroyed the whole economy of nature1 had not this beautiful arrangement been provided by the all-wise ,creator4 ,,chapter ,,three4 ,,waves--,,system ,,in ,,all ,,things--,,value ,,of ,,scientific ,,knowledge--,,illustrative ,,anecdote--,,height ,,of ,,waves--,,dr4 ,,scoresby--,,size1 ,,velocity1 ,,and ,,awful ,,power ,,of ,,waves--,,anecdotes ,,regarding ,,them--,,tides4 ,when a man stands on the deck of some tight-built ship1 holding on to the weather bulwarks1 and gazing with unphilosophic eye through the blinding spray at the fury of the tempest--by which the billows are made to roll around him like liquid mountains1 and the ship is tossed beneath him like a mere chip1 the sport and plaything of the raging waters--he is apt to think1 should his thoughts turn in that direction at all1 that all is unmitigated confusion2 that the winds1 which blew west yesterday and blow east to-day1--shifting1 it may be1 with gusty squalls1 now here1 now there1 in chaotic fury1--are actuated by no laws1 governed by no directing power4 ,yet no thought could be more unphilosophical than this4 ,apart altogether from divine revelation1 by which we are informed that all deeps1 fire1 and hail1 snow1 and vapour1 and stormy wind1 are fulfilling ,god's word 7which information we are bound to receive as a matter of faith if we be ,christians1 and as a matter of necessity if we be men of common sense1 because it is mere absurdity to suppose that the stormy winds1 etcetera1 are not fulfilling ,god's word--or will71 we now know1 to a great extent from practical experience and scientific investigation1 that the winds blow and the waters of the ocean flow in grand1 regular1 uninterrupted currents4 ,amongst these there are numberless eddies1 which1 perhaps1 have tended to fill our minds with the idea of irregularity and confusion2 but which1 nevertheless1 as well as the grand currents themselves1 are subject to law1 and are utterly devoid of caprice4 ,in regard to these matters there is much about which we are still in ignorance4 ,but the investigations of late years--especially those conducted under the superintendence of ,captain ,maury of the ,american ,navy1 and ,doctors ,carpenter and ,thompson of ,england--have shown that our atmosphere and our ocean act in accordance with a systematic arrangement1 many facts regarding which have been discovered1 and turned1 in some cases1 to practical account4 ,see ,note #a4 ,a very interesting instance of the practical use to which scientific inquiry can be turned1 even in its beginnings1 is given by ,maury4 ,after telling us of the existence and nature of a current in the ocean called the ,gulf ,stream1 he gives the following account of the manner in which upon one occasion be made use of his theoretical knowledge4 ,in the month of ,december #ahec1 the fine steam-ship ,san ,francisco sailed from ,new ,york with a regiment of ,united ,states troops on board1 bound for ,california by way of ,cape ,horn4 ,she was overtaken1 while crossing the ,gulf ,stream1 by a gale of wind1 in which she was dreadfully crippled4 ,her decks were swept1 and1 by one single blow of those terrible seas that the storms raise in the ,gulf ,stream1 more than in any other part of the ,atlantic1 one hundred and seventy-nine souls1 officers and soldiers1 were washed overboard and drowned4 ,the day after this disaster she was seen by one vessel1 and again1 the next day1 ,december #bfth1 by another2 but neither of them could render her any assistance4 ,when these two vessels arrived in the ,united ,states and reported what they had seen1 the most painful apprehensions were entertained by friends for the safety of those on board the steamer4 ,vessels were sent out to search for and relieve her4 ,but where should these vessels go8 ,where should they look8 ,an appeal was made to know what light the system of researches carried on at the ,national ,observatory concerning winds and currents could throw upon the subject4 ,the materials they had been discussing were examined1 and a chart was prepared to show the course of the ,gulf ,stream at that season of the year4 ,two revenue cutters were then appointed to proceed to sea in search of the steamer1 and ,maury was requested to furnish them with instructions4 ,it will be observed here that the gentleman thus appealed to was at the time engaged in his study at ,washington1 utterly ignorant of all that had occurred within the previous few weeks on the stormy ,atlantic1 except through the reports brought thence by ships4 ,these reports furnished him with meagre data to proceed upon--simply that a crippled steamer had been seen in a certain latitude and longitude on a particular day4 ,but this information was sufficient for the practical man of science4 ,proceeding upon the supposition that the steamer had been completely disabled1 he drew two lines on the chart to define the limits of her drift4 ,this his previous knowledge of the flow of the ,gulf ,stream at all seasons of the year enabled him to do4 ,between these two lines1 he said1 the steamer1 if she could neither steam nor sail after the gale1 had drifted4 ,and that she could neither steam nor sail he had good reason to suppose from the account of her brought in by the vessels above mentioned4 ,a certain point was marked on the chart as being the spot where the searching vessels might expect to fall in with the wreck4 ,while these preparations were being made1 two ships fell in with the wreck and relieved the crew4 ,this1 however1 was not known at the time by the anxious friends on shore4 ,the cutters sailed on their mission1 and reached the indicated spot in the sea1 where1 of course1 their assistance was now unnecessary4 ,but when the vessels that had relieved the crew of the wreck arrived in harbour and reported where the wreck had been last seen1 it was found to be within a few miles of the spot indicated by ,maury6 ,thus1 upon very slight data1 a man of science and observation was enabled1 while seated in his study1 to follow the drift of a wrecked vessel over the pathless deep1 and to indicate to a rescue party1 not only the exact course they ought to steer1 but the precise spot where the wreck should be found4 ,the waves of the ocean are by no means so high as people imagine4 ,their appearance in the ,atlantic or ,pacific1 when raised by a violent storm1 is indeed very awful1 and men have come to speak of them as being mountains of water4 ,but their sublime aspect and their tumultuous state of agitation have contributed much to deceive superficial observers as to their real height4 ,scientific men have measured the height of the waves4 ,not many years ago a vessel1 while crossing the ,atlantic1 was overtaken by a violent storm4 ,the sea rose in its might2 the good ship reeled under the combined influence of wind and waves4 ,while the majority of the passengers sought refuge from the driving spray in the cabin1 one eccentric old gentleman was seen skipping about the deck with unwonted activity--now on the bulwarks1 now on the quarter-deck1 and anon in the rigging2 utterly regardless of the drenching sea and the howling wind1 and seeming as though he were a species of human stormy petrel4 ,this was the celebrated ,dr ,scoresby2 a man who had spent his youth and manhood in the whale-fishing2 who1 late in life1 entered the ,church1 and1 until the day of his death1 took a special delight in directing the attention of sailors to ,him whose word stilled the tempest and bade the angry waves be calm4 ,being an enthusiast in scientific research1 ,dr ,scoresby was availing himself of the opportunity afforded by this storm to measure the waves6 ,others have made similar measurements1 and the result goes to prove that waves seldom or never rise much more than ten feet above the sea-level4 ,the corresponding depression sinks to the same depth1 thus giving the entire height of the largest waves an elevation of somewhere between twenty and thirty feet4 ,when it is considered that sometimes the waves of the sea 7especially those off the ,cape of ,good ,hope7 are so broad that only a few of them occupy the space of a mile1 and that they travel at the rate of about forty miles an hour1 we may have some slight idea of the grandeur as well as the power of the ocean billows4 ,the forms represented in our illustration are only wavelets on the backs of these monster waves4 ,waves travel at a rate which increases in proportion to their size and the depth of water in which they are formed4 ,every one knows that on most lakes they are comparatively small and harmless4 ,in some lakes1 however1 such as ,lake ,superior in ,north ,america1 which is upwards of three hundred miles long1 the waves are so formidable as to resemble those of the ocean1 and they are capable of producing tremendous effects4 ,but the waves of the sea1 when roused to their greatest height1 and travelling at their greatest speed1 are terrible to behold4 ,their force is absolutely irresistible4 ,sometimes waves of more than usually gigantic proportions arise1 and1 after careering over the broad sea in unimpeded majesty1 fall with crushing violence on some doomed shore4 ,they rush onward1 pass the usual barriers of the sea-beach1 and do not retire until horrible devastation has been carried far into the land4 ,maury gives the following anecdote from the notes of a ,russian officer1 which shows the awful power of such waves4 ,on the #bcrd of ,december #ahed1 at #i3de a4m41 the shocks of an earthquake were felt on board the ,russian frigate ,diana1 as she lay at anchor in the harbour of ,simoda1 not far from ,jeddo in ,japan4 ,in fifteen minutes afterwards 7#aj o'clock7 a large wave was observed rolling into the harbour1 and the water on the beach to be rapidly rising4 ,the town1 as seen from the frigate1 appeared to be sinking4 ,this wave was followed by another2 and when the two receded1 which was at fifteen minutes past ten1 there was not a house1 save an unfinished temple1 left standing4 ,these waves continued to come and go until half-past two p4m41 during which time the frigate was thrown on her beam-ends five times2 a piece of her keel1 eighty-one feet long1 was torn off2 holes were knocked in her by striking on the bottom1 and she was reduced to a wreck4 ,in the course of five minutes the water in the harbour fell1 it is said1 from twenty-three to three feet1 and the anchors of the ship were laid bare4 ,there was a great loss of life2 many houses were washed into the sea1 and many junks carried up--one two miles inland--and dashed to pieces on the shore4 ,the day was beautifully fine1 and no warning was given of the approaching convulsion3 the sea was perfectly smooth when its surface was broken by the first wave4 ,monster waves of this kind occur at regular intervals1 among the islands of the ,pacific1 once and sometimes twice in the year2 and this without any additional influence of an earthquake1 at least in the immediate neighbourhood of the islands1 though it is quite possible that earthquakes in some remote part of the world may have something to do with these waves4 ,one such wave is described as breaking on one of these islands with tremendous violence4 ,it appeared at first like a dark line1 or low cloud1 or fog-bank1 on the sea-ward horizon4 ,the day was fine though cloudy1 and a gentle breeze was blowing2 but the sea was not rougher1 or the breaker on the coral reef that encircled the island higher1 than usual4 ,it was supposed to be an approaching thunder-storm2 but the line gradually drew nearer without spreading upon the sky1 as would have been the case had it been a thunder-cloud4 ,still nearer it came1 and soon those on shore observed that it was moving swiftly towards the island2 but there was no sound until it reached the smaller islands out at sea4 ,as it passed these1 a cloud of white foam encircled each and burst high into the air4 ,this appearance was soon followed by a loud roar1 and it became evident that the object was an enormous wave4 ,when it approached the outer reef1 its awful magnitude became more evident4 ,it burst completely over the reef at all points1 with a deep1 continuous roar2 yet1 although part of its force was thus broken1 on it came1 as if with renewed might1 and finally fell upon the beach with a crash that seemed to shake the solid earth2 then1 rushing impetuously up into the woods1 it levelled the smaller trees and bushes in its headlong course2 and1 on retiring1 left a scene of wreck and desolation that is quite indescribable4 ,storm-waves1 as those unusually gigantic billows are called1 are said to be the result of the removal of atmospheric pressure in certain parts of the ocean over which a storm is raging4 ,this removal of pressure allows the portion thus relieved to be forced up high above the ordinary sea-level by those other parts that are not so relieved4 ,the devastating effects of these storm-waves is still further illustrated by the total destruction of ,coringa1 on the ,coromandel ,coast1 in #aghi4 ,during a hurricane1 in ,december of that year1 at the moment when a high tide was at its highest point1 and the north-west wind was blowing with fury1 accumulating the waters at the head of the bay1 three monstrous waves came rolling in from the sea upon the devoted town1 following each other at a short distance4 ,the horror-stricken inhabitants had scarcely time to note the fact of their approach1 when the first wave1 sweeping everything in its passage1 carried several feet of water into the town4 ,the second swept still further in its destructive course1 inundating all the low country4 ,the third1 rushing onward in irresistible fury1 overwhelmed everything1 submerging the town and twenty thousand of its inhabitants4 ,vessels at anchor at the mouth of the river were carried inland2 and the sea on retiring left heaps of sand and mud1 which rendered it a hopeless task either to search for the dead or for buried property4 ,we have spoken of waves travelling at such and such a rate1 but they do not in reality travel at all4 ,it is the undulation1 or1 so to speak1 the motion of a wave1 that travels2 in the same manner that a wave passes from one end of a carpet to the other end when it is shaken4 ,the water remains stationary1 excepting the spray and foam on the surface1 and is only possessed of a rising and sinking motion4 ,this undulatory motion1 or impulse1 is transmitted from each particle of water to its neighbouring particle1 until it reaches the last drop of water on the shore4 ,but when a wave reaches shallow water it has no longer room to sink to its proper depth2 hence the water composing it acquires actual motion1 and rushes to the land with more or less of the tremendous violence that has been already described4 ,waves are caused by wind1 which first ruffles the surface of the sea into ripples1 and then1 acting with ever-increasing power on the little surfaces thus raised1 blows them up into waves1 and finally into great billows4 ,sometimes1 however1 winds burst upon the calm ocean with such sudden violence that for a time the waves cannot lift their heads4 ,the instant they do so1 they are cast down and scattered in foam1 and the ocean in a few minutes presents the appearance of a cauldron of boiling milk6 ,such squalls are extremely dangerous to mariners1 and vessels exposed to them are often thrown on their beam-ends1 even though all sail has been previously taken in4 ,generally speaking1 however1 the immediate effect of wind passing either lightly or furiously over the sea is to raise its surface into waves4 ,but these waves1 however large they may be1 do not affect the waters of the ocean more than a few yards below its surface4 ,the water below their influence is comparatively calm1 being affected only by ocean currents4 ,the tides of the sea--as the two great flowings and ebbings of the water every twenty-four hours are called--are caused principally by the attractive influence of the moon1 which1 to a small extent1 lifts the waters of the ocean towards it1 as it passes over them1 and thus causes a high wave4 ,this wave1 or current1 when it swells up on the land1 forms high tide4 ,when the moon's influence has completely passed away1 it is low tide4 ,the moon raises this wave wherever it passes2 not only in the ocean directly under it1 but1 strange to say1 it causes a similar wave on the opposite side of the globe4 ,thus there are two waves always following the moon1 and hence the two high tides in the twenty-four hours4 ,this second wave has been accounted for in the following way3 ,the cohesion of particles of water is easily overcome4 ,the moon1 in passing over the sea1 separates the particles by her attractive power1 and draws the surface of the sea away from the solid globe4 ,but the moon also attracts the earth itself1 and draws it away from the water on its opposite side thus causing the high wave there1 as represented in the diagram1 figure #a4 ,the sun has also a slight influence on the tides1 but not to such an extent as the moon4 ,when the two luminaries exert their combined influence in the same direction1 they produce the phenomenon of a very high or spring-tide1 as in figure #b1 where the tide at a and b has risen extremely high1 while at c and d it has fallen correspondingly low4 ,when they act in opposition to each other1 as at the moon's quarter1 there occurs a very low or neap-tide4 ,in figure #c the moon has raised high tide at a and b1 but the sun has counteracted its influence to some extent at c and d1 thus producing neap-tides1 which neither rise so high nor fall so low as do other tides4 ,tides attain various elevations in different parts of the world1 partly owing to local influences4 ,in the ,bristol ,channel the tide rises to nearly sixty feet1 while in the ,mediterranean it is extremely small1 owing to the landlocked nature of that sea preventing the tidal wave from having its full effect4 ,up some gulfs and estuaries the tides sweep with the violence of a torrent1 and any one caught by them on the shore would be overtaken and drowned before he could gain the dry land4 ,in the open sea they rise and fall to an elevation of little more than three or four feet4 ,the value of the tides is unspeakable4 ,they sweep from our shores pollution of every kind1 purify our rivers and estuaries1 and are productive of freshness and health all round the world4 ---------------------------------------- -------------------------------- ,the gentlemen here referred to are agreed as to the fact of systematic arrangement of currents1 though they differ in regard

as the most wonderful1 is the ,gulf ,stream4 ,this mighty current has been likened by ,maury to a river in the ocean4 ,in the severest droughts it never fails1 and in the mightiest floods it never overflows4 ,its banks and its bottom are of cold water1 while its current is of warm4 ,it takes its rise in the ,gulf of ,mexico 7hence its name71 and empties into the arctic seas4 ,its current is more rapid than the ,mississippi or the ,amazon1 and its volume more than a thousand times greater4 ,this great current is of the most beautiful indigo-blue colour as far out as the ,carolina coasts2 and its waters are so distinctly separated from those of the sea1 that the line of demarcation may be traced by the eye4 ,its influences on the currents of the sea1 and on the climates and the navigation of the world1 are so great and important1 that we think a somewhat particular account of it cannot fail to interest the reader4 ,the waters of the ,gulf ,stream are salter than those of the sea2 which fact accounts for its deeper blue colour1 it being well known that salt has the effect of intensifying the blue of deep water4 ,the cause of the ,gulf ,stream has long been a subject of conjecture and dispute among philosophers4 ,some have maintained that the ,mississippi river caused it2 but this theory is upset by the fact that the stream is salt--salter even than the sea--while the river is fresh4 ,besides1 the volume of water emptied into the ,gulf of ,mexico by that river is not equal to the three thousandth part of that which issues from it in the form of the ,gulf ,stream4 ,scientific men are still disagreed on this point4 ,they all1 indeed1 seem to hold the opinion that difference of temperature has to do with the origination of the stream2 but while some1 such as ,captain ,maury1 hold that this is the chief cause1 others1 such as ,professor ,thompson1 believe the trade-winds to be the most important agent in the matter4 ,we venture to incline to the opinion that not only the ,gulf ,stream1 but all the constant currents of the sea are due chiefly to difference of temperature and saltness4 ,these conditions alter the specific gravity of the waters of the ocean in some places more than in others2 hence the equilibrium is destroyed1 and currents commence to flow as a natural result1 seeking to restore that equilibrium4 ,but as the disturbing agents are always at work1 so the currents are of necessity constant4 ,other currents there are in the sea1 but they are the result of winds and various local causes2 they are therefore temporary and partial1 while the great currents of the ocean are permanent1 and are1 comparatively1 little affected by the winds4 ,every one knows that when a pot is put on the fire to boil1 the water contained in it1 as soon as it begins to get heated1 commences to circulate4 ,the heated water rises to the top1 the cold descends4 ,when heated more than that which has ascended1 it in turn rises to the surface2 and so there is a regular current established in the pot1 which continues to flow as long as the heating process goes on4 ,this same principle of temperature1 then1 is one of the causes of the ,gulf ,stream4 ,the torrid zone is the furnace where the waters of the ocean are heated4 ,but in this process of heating1 evaporation goes on to a large extent2 hence the waters become salter than those elsewhere4 ,here is another agent called into action4 ,the hot salt waters of the torrid zone at once rush off to distribute their superabundant caloric and salt to the seas of the frigid zones2 where the ice around the poles has kept the waters cold1 and the absence of great heat1 and1 to a large extent1 of evaporation1 has kept them comparatively fresh4 ,in fact1 the waters of the sea require to be stirred1 because numerous agents are at work day and night1 from pole to pole1 altering their specific gravity and deranging1 so to speak1 the mixture4 ,this stirring is secured by the unalterable laws which the ,creator has fixed for the carrying on of the processes of nature4 ,the currents of the sea may be said to be the result of this process of stirring its waters4 ,it is curious and interesting to note the apparently insignificant instruments which ,god has seen fit to use in the carrying out of his plans4 ,the smallest coral insect that builds its little cell in the southern seas exercises an influence in the production of the ,gulf ,stream4 ,it has been said1 with some degree of truth1 that one such insect is capable of setting in motion the entire ocean6 ,the coral insect has1 in common with many other marine creatures1 been gifted with the power of extracting from sea water the lime which it contains1 in order to build its cell4 ,the lime thus extracted leaves a minute particle of water necessarily destitute of that substance4 ,before that particle can be restored to its original condition of equality1 every other particle of water in the ocean must part with a share of its superabundant lime6 ,the thing must be done4 ,that bereaved particle cannot rest without its lime4 ,it forthwith commences to travel for the purpose of laying its brother-particles under contribution2 and it travels far and wide--round and round the world4 ,myriads upon myriads of coral insects are perpetually engaged in thus robbing the sea water of its lime2 shells are formed in a similar manner3 so that our particle soon finds itself in company with innumerable other particles of water in a like destitute condition4 ,it rises to the surface4 ,here the sun1 as if to compensate it for the loss of its lime1 bestows upon it an unusual amount of heat2 and the surrounding particles1 not to be outdone1 make it almost unlimited presents of salt4 ,full to overflow with the gifts of its new companions1 it hastens to bestow of its superabundance on less favoured particles2 joins the great army of the ocean's currents2 enters1 perchance1 the ,gulf of ,mexico1 where it is turned back1 and hastens along with the ,gulf ,stream1 with all its natural warmth of character1 to ameliorate the climate of ,great ,britain and the western shores of ,europe4 ,having accomplished this benevolent work1 it passes on1 with some of its heat and vigour still remaining1 to the arctic seas--where it is finally robbed of all its heat and nearly all its salt1 and frozen into an icicle--there for many a long day to exert a chilling influence on the waters and the atmosphere around it4 ,being melted at last by the hot sun of the short arctic summer1 it hurries back with the cold currents of the north to the genial regions of the equator1 in search of its lost caloric and salt1 taking in a full cargo of lime1 etcetera1 as it passes the mouths of rivers4 ,arrived at its old starting-point1 our wanderer receives once more heat and salt to the full1 parts with its lime1 and at once hastens off on a new voyage of usefulness--to give out of its superabundance in exchange for the superabundance of others3 thus quietly teaching man the lesson that the true principles of commerce were carried out in the depths of the sea ages before he discovered them and carried them into practice on its surface4 ,perchance another fate awaits this adventurous particle of water4 ,mayhap1 before it reaches the cold regions of the north1 it is evaporated into the clouds1 and descends upon the earth in fresh and refreshing rain or dew4 ,having fertilised the fields1 it flows back to its parent ocean1 laden with a superabundant cargo of earthy substances1 which it soon parts with in exchange for salt4 ,and thus on it goes1 round and round the world2 down in the ocean's depths1 up in the cloudy sky1 deep in the springs of earth2 ever moving1 ever active1 never lost1 and always fulfilling the end for which it was created4 ,all ocean currents are composed of water in one or other of the conditions just described2--the hot and salt waters of the equator1 flowing north to be cooled and freshened2 the cold and fresh waters of the north1 flowing south to be heated and salted4 ,the ,gulf ,stream is simply the stream of equatorial hot water that flows towards the pole through the ,atlantic4 ,its fountain-head is the region of the equator1 not the ,gulf of ,mexico2 but it is carried1 by the conformation of the land1 into that gulf and deflected by it1 and from it out into the ocean in the direction of ,europe4 ,this stream in the ,atlantic is well defined1 owing to the comparative narrowness of that sea4 ,the ,gulf ,stream1 then1 is like a river of oil in the ocean1--it preserves its distinctive character for more than three thousand miles4 ,it flows towards the polar regions1 and the waters of those regions flow in counter-currents towards the equator1 because of the fixed law that water must seek its equilibrium as well as its level1 thus keeping up a continuous circulation of the hot waters towards the north and the cold towards the south4 ,there are similar currents in the ,pacific1 but they are neither so large nor so regular as those of the ,atlantic1 owing to the wide formation of the basin of the former sea4 ,the effect of the ,gulf ,stream on climate is very great4 ,the dreary fur-trading establishment of ,york ,factory1 on the shores of ,hudson's ,bay1 is surrounded by a climate of the most rigorous character--the thermometer seldom rising up so high as zero during many months1 and often ranging down so low as #ej degrees below zero1 sometimes even lower1 while the winter is seven or eight months long3 the lakes and rivers are covered with ice upwards of six feet thick1 and the salt sea itself is frozen4 ,yet this region lies in the same latitude with ,scotland1 ,york ,factory being on the parallel of #eg degrees north1 which passes close to ,aberdeen6 ,the difference in temperature between the two places is owing very much1 if not entirely1 to the influence of the ,gulf ,stream4 ,starting from its caldron in the ,gulf of ,mexico1 it carries a freight of caloric towards the ,north ,atlantic4 ,owing partly to the diurnal motion of the ,earth on its axis1 its flow trends towards the east2 hence its warm waters embrace our favoured coasts1 and ameliorate our climate1 while the eastern sea-board of ,north ,america is left1 in winter1 to the rigour of unmitigated frost4 ,but besides the powerful influence of this current on climate1 it exerts a very considerable influence on navigation4 ,in former times1 when men regarded the ocean as a great watery waste--utterly ignorant of the exquisite order and harmonious action of all the varied substances and conditions which prevail in the sea1 just as much as on the land--they committed themselves to the deep as to a blind chance1 and took the storms and calms they encountered as their inevitable fate1 which they had no means of evading4 ,ascertaining1 as well as they could from the imperfect charts of those days1 the position of their desired haven1 they steered straight for it through fair weather and foul1 regarding interruptions and delays as mere unavoidable matters of course4 ,but when men began to study the causes and effects of the operation of those elements in the midst of which they dwelt1 they soon perceived that order reigned where before they had imagined that confusion revelled2 and that1 by adapting their operations to the ascertained laws of ,providence1 they could1 even upon the seemingly unstable sea1 avoid dangers and delays of many kinds1 and oftentimes place themselves in highly favourable circumstances4 ,navigators no longer dash recklessly into the ,gulf ,stream1 and try to stem its tide1 as they did of yore2 but1 as circumstances require1 they either take advantage of the counter-currents which skirt along it1 or avail themselves of the warm climate which it creates even in the midst of winter4 ,there is a certain spot in the ,atlantic known by the name of the ,sargasso ,sea1 which is neither more nor less than a huge ocean-eddy1 in which immense quantities of sea-weed collect4 ,the weed floats so thickly on the surface as to give to the sea the appearance of solid land2 and ships find extreme difficulty in getting through this region1 which is rendered still further unnavigable by the prevalence of long-continued calms4 ,this ,sargasso ,sea is of considerable extent1 and lies off the west coast of ,africa1 a little to the north of the ,cape ,verd ,islands4 ,in former years1 ships used to get entangled in this weedy region for weeks together1 unable to proceed on their voyage4 ,the great ,columbus fell in with it on his voyage to ,america1 and his followers1 thinking they had reached the end of the world1 were filled with consternation4 ,this ,sargasso ,sea lies in the same spot at the present day1 but men now know its extent and position4 ,instead of steering straight for port1 they proceed a considerable distance out of their way1 and1 by avoiding this calm region1 accomplish their voyages with much greater speed4 ,the ocean currents have been1 by repeated and long-continued investigation1 ascertained and mapped out2 so also have the currents of the atmosphere1 so that1 now-a-days1 by taking advantage of some of these currents and avoiding others1 voyages are performed1 not only in much shorter time1 but with much greater precision and certainty4 ,as it was with ocean currents long ago1 so was it with atmospheric4 ,navigators merely put to sea1 steered as near as possible on their direct course1 and took advantage of such winds as chanced to blow4 ,now they know whither to steer in order to meet with such winds and currents as will convey them in the shortest space of time to the end of their voyage4 ,the knowledge necessary to this has not been gained by the gigantic effort of one mind1 nor by the accidental collocation of the results of the investigations of many ordinary minds4 ,but a few master-minds have succeeded in gathering within their own grasp the myriad facts collected by thousands of naval men1 of all countries1 in their various voyages2 and1 by a careful comparison and philosophical investigation of these facts1 they have ascertained and systematised truths which were before unknown1 and have constructed wind and current charts1 by the use of which voyages are wonderfully shortened1 commercial enterprises greatly facilitated1 and the general good and comfort of nations materially advanced4 ,the truth of this has of late been proved by incontestable facts4 ,for instance1 one year particular note was taken of the arrival of all the vessels at the port of ,san ,francisco1 in ,california2 and it was found that of #abd vessels from the ,atlantic coast of the ,united ,states1 #gj were possessed of ,maury's wind and current charts4 ,the average passage of these #gj vessels1 on that long voyage round ,cape ,horn1 was #ace days2 while the average of those that sailed without the charts 7that is1 trusted to their own unaided wisdom and experience7 was #adf days4 ,between ,england and ,australia the average length of the voyage out used1 very recently1 to be #abd days4 ,with the aid of these charts it has now been reduced to #ig days on the average4 ,the saving to commerce thus achieved is much greater than one would suppose4 ,at the risk of becoming tedious to uninquiring readers1 we will make a brief extract from ,hunt's ,merchants' ,magazine of #ahed1 as given in a foot-note in ,maury's ,physical ,geography of the ,sea4 ,now1 let us make a calculation of the annual saving to the commerce of the ,united ,states effected by these charts and sailing directions4 ,according to ,mr ,maury1 the average freight from the ,united ,states to ,rio ,janeiro is #ag4g cents per ton per day2 to ,australia1 #bj cents2 to ,california1 also about #bj cents4 ,the mean of this is a little over #ai cents per ton per day2 but1 to be within the mark1 we will take it at #ae1 and include all the ports of ,south ,america1 ,china1 and the ,east ,indies4 ,the sailing directions have shortened the passage to ,california #cj days2 to ,australia1 #bj2 to ,rio ,janeiro1 #aj4 ,the mean of this is #bj2 but we will take it at #ae1 and also include the above-named ports of ,south ,america1 ,china1 and the ,east ,indies4 ,we estimate the tonnage of the ,united ,states engaged in trade with these places at #a1jjj1jjj tons per annum4 ,with these data1 we see that there has been effected a saving for each one of these tons1 of #ae cents per day for a period of #ae days1 which will give an aggregate of #b1bej1jjj dollars 7#dfh1gej pounds7 saved per annum4 ,this is on the outward voyage alone1 and the tonnage trading with all other parts of the world is also left out of the calculation4 ,take these into consideration1 and also the fact that there is a vast amount of foreign tonnage trading between these places and the ,united ,states1 and it will be seen that the annual sum saved will swell to an enormous amount4 ,before the existence of the ,gulf ,stream was ascertained1 vessels were frequently drifted far out of their course in cloudy or foggy weather1 without the fact being known1 until the clearing away of the mists enabled the navigators to ascertain their position by solar observation4 ,now1 not only the existence1 but the exact limits and action of this stream are known and mapped2 so that the current1 which was formerly a hindrance to navigation1 is now made to be a help to it4 ,the line of demarcation between the warm waters of the ,gulf ,stream and the cold waters of the sea is so sharp and distinct1 that by the use of the thermometer the precise minute of a ship's leaving or entering it can be ascertained4 ,and by the simple application of the thermometer to the ,gulf ,stream the average passage from ,england to ,america has been reduced from upwards of eight weeks to little more than four6 ,but this wonderful current is useful to navigators in more ways than one4 ,its waters1 being warm1 carry a mild climate along with them through the ocean even in the depth of winter1 and thus afford a region of shelter to vessels when attempting to make the ,atlantic coast of ,north ,america1 which1 at that season is swept by furious storms and chilled by bitter frosts4 ,the ,atlantic coasts of the ,united ,states are considered to be the most stormy in the world during winter1 and the difficulty of making them used to be much greater in former days than now4 ,the number of wrecks that take place off the shores of ,new ,england in mid-,winter is frightful4 ,all down that coast flows one of the great cold currents from the north4 ,the combined influence of the cold atmosphere above it1 and the warm atmosphere over the ,gulf ,stream1 far out at sea1 produces terrific gales4 ,the month's average of wrecks off that coast has been as high as three a day4 ,in making the coast1 vessels are met frequently by snow-storms1 which clothe the rigging with ice1 rendering it unmanageable1 and chill the seaman's frame1 so that he cannot manage his ship or face the howling blast4 ,formerly1 when unable to make the coast1 owing to the fury of these bitter westerly gales1 he knew of no place of refuge short of the ,west ,indies1 whither he was often compelled to run1 and there await the coming of genial spring ere he again attempted to complete his voyage4 ,now1 however1 the region of the ,gulf ,stream is sought as a refuge4 ,when the stiffened ropes refuse to work1 and the ship can no longer make head against the storm1 she is put about and steered for the ,gulf ,stream4 ,in a few hours she reaches its edge1 and almost in a moment afterwards she passes from the midst of winter into a sea of sunnier heat6 ,now1 as ,maury beautifully expresses it1 the ice disappears from her apparel2 the sailor bathes his limbs in tepid waters4 ,feeling himself invigorated and refreshed with the genial warmth about him1 he realises out there at sea the fable of ,antaeus and his mother ,earth4 ,he rises up and attempts to make his port again1 and is again1 perhaps1 as rudely met and beat back from the north-west2 but each time that he is driven off from the contest1 he comes forth from this stream1 like the ancient son of ,neptune1 stronger and stronger1 until1 after many days1 his freshened strength prevails1 and he at last triumphs1 and enters his haven in safety--though in this contest he sometimes falls to rise no more1 for it is terrible4 ,the power of ocean currents in drifting vessels out of their course1 and in sweeping away great bodies of ice1 is very great2 although1 from the fact that there is no land to enable the eye to mark the flow1 such drifts are not perceptible4 ,one of the most celebrated drifts of modern times1 and the most astonishing on account of its extent1 was that of the ,fox in ,baffin's ,bay in the year #aheg1 a somewhat detailed account of which will be found in a succeeding chapter4 ,the ,gulf ,stream is the cause of many of the most furious storms4 ,the fiercest gales sweep along with it1 and it is supposed that the spring and summer fogs of ,newfoundland are caused by the immense volumes of warm water poured by it into the cold seas of that region4 ,we are told that ,sir ,philip ,brooke found the temperature of the sea on each side of this stream to be at the freezing-point1 while that of its waters was #hj degrees4 ,from this it may be easily seen how great are the disturbing influences around and above it2 for1 as the warm and moist atmosphere over it ascends in virtue of its lightness1 the cold air outside rushes in violently to supply its place1 thus creating storms4 ,the warm waters of this stream do not1 it is believed1 anywhere extend to the bottom of the sea4 ,it has been ascertained1 by means of the deep-sea thermometer1 that they rest upon1 or rather flow over1 the cold waters which are hastening from the north in search of those elements which1 in their wanderings1 they have lost4 ,as cold water is one of the best non-conductors of heat1 the ,gulf ,stream is thus prevented from losing its caloric on its way across the ,atlantic to ameliorate the climates of the western coasts of ,europe1 and moderate the bitterness of the northern seas4 ,were it otherwise1 and this great stream flowed over the crust of the ,earth1 so much of its heat would be extracted1 that the climates of ,france and our own islands would probably resemble that of ,canada4 ,our fields would be covered1 for two1 three1 or four months1 with deep snow2 our rivers would be frozen nearly to the bottom2 our land traffic would perhaps be carried on by means of sledges and carioles2 our houses would require to be fitted with double window-frames and heated with iron stoves and our garments would have to be made of the thickest woollens and the warmest furs4 ,the presence and the unchanging regularity of these great hot and cold currents in the ocean is indicated very clearly by the living inhabitants of the deep4 ,these1 as certainly as the creatures of the land1 are under the influence of climate2 so much so1 that many of them never quit their native region in the sea4 ,all the beautiful and delicate marine creatures and productions which dwell in the warm waters of the south are utterly absent from those shores which are laved by the cold currents that descend from the north2 while1 owing to the influence of the ,gulf ,stream1 we find many of those lovely and singular creatures upon our comparatively northern shores4 ,of late years1 as every one knows1 we have all over the land been gathering these marine gems1 and studying their peculiar habits with deep interest in that miniature ocean the aquarium4 ,in the same parallel on the other side of the ,atlantic none of these little lovers of heat are to be found4 ,on the other hand1 the whale1 delighting as it does to lave its huge warm-blooded body in iced water1 is never found to enter the ,gulf ,stream4 ,thus these fish1 to some extent1 define its position4 ,other fish there are which seem to resemble man in their ability to change their climate at will but1 like him also1 they are apt in so doing to lose their health1 or1 at least1 to get somewhat out of condition4 ,some kinds of fish1 when caught in the waters off ,virginia and the ,carolinas1 are excellent for the table2 but the same species1 when taken off the warm coral banks of the ,bahamas1 are scarcely worth eating4 ,in fact1 we see no reason for doubting that when these fish find their health giving way in the warm regions of the south1 they seek to reinvigorate themselves by change of water2 and1 quitting for a time the beauteous coral groves1 spend a few of the sunnier months of each year in gambolling in the cool regions of the north1 or1 what is much the same thing1 in those cool currents that flow from the north in clearly defined channels4 ,besides its other useful and manifold purposes1 the ,gulf ,stream would seem to be one of the great purveyors of food to the whales4 ,sea-nettles1 or medusae1 are well known to constitute the principal food of that species of whale which is termed the right whale4 ,navigators have frequently observed large quantities of these medusae floating along with the ,gulf ,stream2 and one sea captain in particular fell in with an extraordinarily large quantity of them1 of a very peculiar species1 off the coast of ,florida4 ,as we have said1 no whales ever enter the warm waters of the ,gulf ,stream2 therefore1 at that time at least1 the leviathan could not avail himself of this rich provision4 ,the captain referred to was bound for ,england4 ,on his return voyage he fell in with the same mass of medusae off the ,western ,islands1 and was three or four days in sailing through them4 ,now1 the ,western ,islands is a great place of resort for the whale1 and thither had the ,gulf ,stream been commissioned to convey immense quantities of its peculiar food4 ,we might enlarge endlessly on this great ocean current1 but enough1 we think1 has been said to show that the sea1 instead of being an ocean of unchanging drops1 driven about at random by the power of stormy winds1 is a mighty flood flowing in an appointed course--steady1 regular1 and systematic in its motions1 varied and wonderful in its actions1 benign and sweet in its influences1 as it sweeps mound and round the world1 fulfilling the will of its great ,creator4 ,,chapter ,,five4 ,,the ,,atmospheric ,,ocean--,,order

only creatures that live in this ocean4 ,the human inhabitants of ,earth1 dwell at the bottom of an ocean of air1 which encircles the globe4 ,fish1 however1 have the advantage of us1 inasmuch as they can float and dart about in their ocean1 while we1 like the crabs1 can only crawl about at the bottom of ours4 ,this atmospheric ocean is so closely connected with the sea1 and exercises upon it so constant1 universal1 and important an influence1 that to omit1 in a work of this kind1 very special reference to the winds1 would be almost as egregious an oversight as to ignore the waves4 ,wind1 or atmospheric air in motion1 is the cause of storms1 of waves1 of water-transport through the sky1 and of an incalculable amount of varied phenomena on land and sea4 ,without this great agent no visible motion would ever take place in the sea4 ,its great currents1 indeed1 might flow on 7though even that is questionable71 but its surface would never present any other aspect than that of an unruffled sheet of clear glass4 ,the air1 then1 becomes in this place an appropriate subject of consideration4 ,the ,voice of ,ocean has something very emphatic to say about the atmosphere4 ,in regard to its nature1 it is sufficient to say that atmospheric air is composed of two gases--oxygen and nitrogen4 ,like the sea1 the atmosphere is an ocean which flows1 not in chaotic confusion1 but in regular1 appointed courses2 acting in obedience to the fixed1 unvarying laws of the ,almighty1 and having currents1 counter-currents1 and eddies also1 just like the watery ocean1 which exercise a specific and salutary influence where they exist4 ,the offices of the atmosphere are thus quaintly enumerated by ,maury3-- ,the atmosphere is an envelope or covering for the distribution of light and heat over the ,earth2 it is a sewer into which1 with every breath we draw1 we cast vast quantities of dead animal matter2 it is a laboratory for purification1 in which that matter is recompounded1 and wrought again into wholesome and healthful shapes2 it is a machine for pumping up all the rivers from the sea1 and for conveying the water from the ocean to their sources in the mountains4 ,it is an inexhaustible magazine1 marvellously stored2 and upon the proper working of this machine depends the well-being of every plant and animal that inhabits the ,earth4 ,an element whose operations are so manifold and so important could not fail to engage the study of philosophic men in all ages2 but so difficult has been that study that little progress was made until very recently1 when men1 acting in unison in all parts of the world1 have1 by collating their observations1 become acquainted with some of those laws which govern the atmosphere1 and direct its courses and velocities4 ,in early ages very little indeed was known about the wind beyond the palpable facts of its existence1 its varied condition1 and its tremendous power2 and men's observations in regard to it did not extend much beyond the noting of those peculiar and obvious aspects of the sky which experience taught them to regard as evidences of approaching storm4 ,but1 although such aspects of the heavens were1 and always will be1 pretty safe and correct indicators of the ,weather1 they are by no means infallible2 and in some regions and under certain conditions they are wanting altogether4 ,when the sea captain observes a lowering aspect of the sky1 with1 it may be1 a dark line above the distant edge of the sea1 he knows--however calm and unruffled may be the ocean around him--that wind may be expected2 and1 calling the crew1 he orders sail to be taken in1 and preparation made for the approaching breeze4 ,but there are times when no such warning is given1 when the atmospheric is perfectly still1 the sea calm as glass1 and the vessel floats motionless with her sails hanging idly from the yards1 as if she were3 ,a painted ship upon a painted ,ocean4 ,suddenly1 and before preparation can be made to withstand it1 the hurricane bursts in appalling fury over the sea3 the sails are blown to ribbons2 the masts1 perhaps1 broken down2 and frequently the vessel itself overwhelmed and sent to the bottom4 ,many a gallant ship1 which has left the harbour ably commanded and well manned1 and never more been heard of1 has doubtless gone down in sudden storms such as those we have referred to4 ,but the inventions of science have now very much lessened the danger of these storms4 ,the barometer1 by the sudden fall of its column of mercury1 tells1 as plainly and certainly as if it spoke with an audible voice1 that a storm is approaching1 even though all nature should appear to contradict the fact by its calm and serene aspect2 so that the crew thus warned have time to furl the sails1 fasten down the hatches1 and otherwise prepare to face the impending danger4 ,the atmosphere flows in a grand harmonious system of currents and counter-currents1 with their corresponding eddies1 just like the ocean2 and the grand final results of its varied action are to equalise in some degree the temperatures of the world1 to carry off and distribute moisture where it is required1 to sweep away noxious vapours1 and generally to ventilate the ,earth and gladden the heart of man4 ,the primary cause of all wind is the combined action of heat and cold4 ,if the world were heated with perfect equality all round1 there would be1 as far at least as heat is concerned1 a perfect and permanent stagnation of the atmosphere2 and this would speedily result in the destruction of every living thing4 ,but by the varied and beautiful arrangements which the ,almighty has made in nature ,he has secured a regular flow of atmospheric currents1 which will continue unalterably to move as long as the present economy of things exists4 ,the intense and constant action of the sun's rays in the torrid zone produces great heat1 while the less powerful and frequently interrupted influence of his rays in the frigid zones induces extreme cold4 ,hence we have in one region heated air1 in another cool air4 ,now1 the effect of heat upon air is to expand it1 make it light1 and cause it to rise4 ,the moment it does so1 the cold air rushes in to supply its place2 and this rushing in of the cold air is what we call wind4 ,it may surprise many people to be told that there are only two great and never-ceasing courses of the winds of this world--namely1 north and south4 ,they flow perpetually from the equator to the poles1 and from the poles to the equator4 ,all the irregularities and interruptions that we observe are mere temporary and partial deflections from this grand course4 ,the heated air at the equator rises continually and flows in an upper current towards the pole1 getting gradually cooled on its way north4 ,that from the pole flows in an under current towards the equator1 getting gradually heated on its way south4 ,we speak only of the ,northern ,hemisphere1 for the sake of simplifying explanation1--the action of the great wind-current in the ,southern ,hemisphere is precisely similar4 ,but our broad simple statement about the upper current from the equator1 and the under current from the pole1 requires a slight modification1 which we thought it best not to mingle with the statement itself4 ,the heated air from the equator does indeed commence to flow in an upper current1 and the cooled air from the pole in an under current2 but1 as the upper currents of air are speedily cooled by exposure to space1 and the under currents are heated by contact with the earth's surface1 they constantly change places--the lower current becoming the upper1 and vice versa4 ,but they do not change direction4 ,the ,equatorial ,current ascends1 rushes north to a point about latitude #cj degrees1 where1 being sufficiently cooled1 it swoops down1 and continues its ,northward rush along the earth4 ,at another point the ,polar ,current quits the earth1 and soaring up1 in consequence of its recently acquired heat1 becomes the upper current4 ,this change in the two currents takes place twice in their course4 ,of course1 the effect of these changes is to produce north winds in one latitude and south winds in another1 according to the particular wind 7equatorial or polar7 that happens to be in contact with the earth4 ,at the points where these two currents cross1 in changing places1 we necessarily have calms1 or conflicting and variable winds4 ,here1 then1 we have the first of the constant disturbing causes1 and of apparent irregularities1 in the winds4 ,the ,earth1 as every one knows1 whirls rapidly on its axis from west to east4 ,at the equator the whirl is so rapid that the atmosphere does not at once follow the ,earth's motion4 ,it lags behind1 and thus induces an easterly tendency to the winds1 so that a north wind becomes a north-east1 and a south wind a south-east4 ,here we have another constant cause of variation from the northerly and southerly flow4 ,we thus account for an easterly tendency to the winds1 but whence their westerly flow8 ,it is simply explained thus3 ,the motion of the ,earth is greatest at the equator4 ,it diminishes gradually towards the poles1 where there is no motion at all4 ,the atmosphere partakes of the ,earth's motion when in contact with it2 and when thrown upwards by heat1 as at the equator1 it keeps up the motion for some time1 as it meets with no resistance there4 ,bearing this in mind1 let us now follow a gush of warm atmosphere from the equator4 ,it rushes up1 and1 turning north and south1 seeks the poles4 ,we follow the northern division4 ,when it left the ,earth it had acquired a very strong motion towards the east1--not so great as that of the ,earth itself1 but great enough to be equivalent to a furious gale from west to east4 ,if we suppose this air to redescend whence it rose1 it would1 on reaching the equator1 find the ,earth going too fast for it4 ,it would lag a little1 and become a gentle easterly breeze4 ,but now1 throw aside this supposition2--our breeze rushes north2 at latitude #cj degrees it has got cooled1 and swoops down upon the ,earth2 but the ,earth at this latitude is moving much slower than at the equator2 the wind1 however1 has lost little or none of its easterly velocity4 ,on reaching the ,earth it rushes east much faster than the ,earth itself1 and thus becomes a westerly gale4 ,there are1 however1 many other agents at work1 which modify and disturb what we may call the legitimate flow of the wind2 and these agents are diverse in different places1 so that the atmosphere is turned out of a straight course1 and is caused to deflect1 to halt1 and to turn round3 sometimes sweeping low as if in haste2 at other times pausing1 as if in uncertainty2 and often whirling round1 as if in mad confusion4 ,to the observer1 who sees only the partial effects around his own person1 all this commotion seems but the disorderly action of blind chance2 but to the eye of ,him who sees the end from the beginning1 we may certainly conclude that naught is seen but order and perfect harmony4 ,and to the eye of ,science there now begins to appear1 in what was formerly an atmospheric chaos1 an evidence of design and system1 which is not1 indeed1 absolutely clear1 but which is nevertheless abundantly perceptible to minds that cannot hope in this life to see otherwise than through a glass1 darkly4 ,the causes which modify the action of the winds are1 as we have said1 various4 ,local causes produce local currents4 ,a clear sky in one region allows the sun's rays to pour upon1 let us say1 the ocean1 producing great heat2 the result of which is evaporation4 ,aqueous vapour is very light1 therefore it rises2 and in doing so the aqueous particles carry the air up with them1 and the wind necessarily rushes in below to supply its place4 ,the falling of heavy rain1 in certain conditions of the atmosphere1 has the effect of raising wind4 ,electricity has also1 in all probability1 something to do with the creation of motion in the atmosphere4 ,now1 as these are all local causes1 they produce local--or what1 in regard to the whole atmosphere1 may be termed irregular--effects4 ,and as these causes or agents are in ceaseless operation at all times1 so their disturbing influence is endless2 and hence the apparent irregularity in the winds4 ,but these causes are themselves1 not less than their results1 dependent on other causes or laws1 the workings of which are steady and unvarying2 and the little irregularities that appear to us in the form of fluctuating and changing winds and calms may be compared to the varying ripples and shifting eddies of a river1 whose surface is affected by the comparatively trifling influences of wind1 rain1 and drought1 but whose grand onward course is never for a single moment interrupted4 ,among these disturbing influences1 the ,gulf ,stream is a very important one4 ,it is constantly sending up large volumes of steam1 which1 rising into the air1 induce a flow of wind from both sides towards its centre4 ,and many of the storms that arise in other parts of the ,atlantic make for this stream1 and follow its course4 ,so much has been ascertained by scientific investigation of the winds1 that we can now distinctly map out the great belts or currents which pass right round the world4 ,we can tell in which parallels winds with easting1 and in which those with westing1 in them1 will be most frequently found2 and by directing our course to such places1 we can to a certain extent count upon profiting by the winds that will be most suitable4 ,before the facts of atmospheric circulation were known1 mariners sailed by chance4 ,if they happened to get into the belt of wind that suited them1 their voyages were favourable2 if they got into the wrong region1 their voyages were unfavourable1--that was all4 ,but they had no idea that there was any possibility of turning the tables1 and1 by a careful investigation of the works of the ,creator1 coming at last to such knowledge as would enable them to reduce winds and waves1 in a great degree1 to a state of slavery1 instead of themselves being at their mercy4 ,the world may be said to be encircled by a succession of belts of wind1 which blow not always in the same direction1 but almost invariably with the same routine of variations4 ,a vessel sailing from north to south encounters these belts in succession4 ,to mariners of old1 these varying winds seemed to blow in utter confusion4 ,to men of the present time1 their varied action is counted on with some degree of certainty4 ,the reason why men were so long in discovering the nature of atmospheric circulation was1 that they were not sufficiently alive to the immense value of united effort4 ,they learned wisdom chiefly from personal experience--each man for himself2 and in the great majority of cases1 stores of knowledge1 that would have been of the utmost importance to mankind1 were buried with the individuals who had laid them up4 ,moreover1 the life of an individual was too short1 and his experience too limited1 to enable him to discover any of the grand laws of ,nature2 and as there was no gathering together of information from all quarters1 and all sorts of men1 and all seasons 7as there is now71 the knowledge acquired by individuals was almost always lost to the world4 ,thus men were ever learning1 but never arriving at a knowledge of the truth4 ,may we not here remark1 that this evil was owing to another evil-- namely1 man's ignorance of1 or indifference to1 the duty of what we may term human communication8 ,as surely as gravitation is an appointed law of ,god1 so surely is it an appointed duty that men shall communicate their individual knowledge to each other1 in order that the general knowledge of the species may advance and just in proportion to the fidelity with which men obey this duty--the care and ability with which they collate and systematise and investigate their knowledge--will be the result of their efforts4 ,in order to make the above remarks more clear as regards atmospheric phenomena1 let us suppose the case of a sailor who makes the same voyage every year1 but not precisely at the same time each year 7and it must be remembered that the rigid punctuality at starting which now holds good did not exist in former times74 ,in his first voyage he had to cross1 say1 four of the wind-belts4 ,while crossing belt number one1 he experiences south-west winds chiefly1 and1 being an observant man1 notes the fact4 ,in belt number two he encounters westerly winds4 ,in number three he is in a region of variable winds and calms4 ,in this region the winds blow all round the compass1 averaging about three months from each quarter4 ,but our sailor does not know that2 he does not stay there all the year to make notes2 he passes on1 having recorded his experience4 ,in crossing belt number four1 he finds the prevailing winds to be easterly4 ,next year he sets forth again but merchants are not always punctual4 ,the lading cannot be completed in time1 or adverse winds render the setting sail unadvisable4 ,at length1 after a month or six weeks' delay1 he proceeds on his voyage1 and finds belt number one perhaps much the same as last year4 ,he congratulates himself on his good fortune1 and notes his observations2 but in belt number two1 the wind is somewhat modified1 owing to its being later in the season1--it is rather against him4 ,in number three it is right in his teeth1 whereas last year it was quite in his favour4 ,in number four1 which we will suppose is the trade-wind belt 7of which more hereafter71 he finds the wind still easterly4 ,here1 then1 is the groundwork of confusion in our sailor's mind4 ,he has not the remotest idea that in belt number one the wind blows chiefly1 but not always1 in one particular direction2 that in number four it blows invariably in one way2 and that in number three it is regularly irregular4 ,in fact1 he does not know that such belts exist at all1 and his opportunities of observing are not sufficiently frequent or prolonged to enable him to ascertain anything with certainty4 ,now1 when we remember that in this imperfect experience of his he is still further misled by his frequently encountering local vicissitudes--such as storms and calms resulting from local and temporary causes--we see how confusion becomes worse confounded4 ,no doubt he does gather some few crumbs of knowledge2 but he is called on1 perhaps1 to change his scene of action4 ,another ship is given to him1 another route entered on1 and he ceases altogether to prosecute his inquiries in the old region4 ,or old age comes on2 and even although he may have been beginning to have a few faint glimmerings as to laws and systems in his mind1 he has not the power to make much of these4 ,he dies2 his knowledge is1 to a very large extent1 lost1 and his log-books disappear1 as all such books do1 nobody knows or cares where4 ,now this state of things has been changing during the last few years4 ,log-books are collected in thousands4 ,the experiences of many men1 in reference to the same spots in the same years1 months1 and even hours1 are gathered1 collated1 and compared2 and the result is1 that although there are conflicting elements and contradictory appearances1 order has been discovered in the midst of apparent confusion1 and scientific men have been enabled to pierce through the chaos of littlenesses by which the world's vision has been hitherto obscured1 and to lay bare many of those grand progressions of nature which move unvaryingly with stately step through space and time1 as the river1 with all its minor eddies and counter-currents1 flows with unvarying regularity to the ocean4 ,,chapter ,,six4 ,,trade-,,winds--,,storms--,,their ,,effects--,,monsoons--,,their ,,value--,,land ,,and ,,sea

,,atmosphere--,,value ,,of ,,atmospheric ,,circulation--,,height ,,of ,,atmosphere4 ,before proceeding to speak of the power and the dreadful effects of wind1 it is necessary to say a word or two about the trade-winds4 ,it is supposed that the trades derived their name from the fact of their being favourable to navigation1 and1 therefore1 to trade4 ,they consist of two belts of wind1 one on each side of the equator1 which blow always in the same direction4 ,in the last chapter it was explained that the heated atmosphere at the equator rises1 and that the cooler atmosphere from the poles rushes in to supply its place4 ,that which rushes from the south pole is1 of course1 a south wind1 that from the north pole a north wind2 but1 owing to the ,earth's motion on its axis from west to east1 the one becomes a north-east1 the other a south-east wind4 ,these are the north-east and the ,south-east trades4 ,they blow regularly--sometimes gently1 sometimes fiercely--all the year round4 ,between the two is a belt of calms and changeable breezes1 varying from #aej to #ejj miles broad-- according to the time of the year--where there are frequent and violent squalls1 of very short duration1 accompanied with heavy rains4 ,this region is called by seamen the doldrums1 and considerable trouble and difficulty do ships experience in crossing it4 ,it has already been explained that about latitude #cj degrees1 the upper current of wind from the south descends4 ,at the same point the upper current from the north also descends4 ,they cut through each other1 and the point where these two cut each other is the northern limit of the north-east trade-winds4 ,the same explanation holds in regard to the southern limit of the south-east trades4 ,in the accompanying diagram the arrows within the circle point out the direction of the north-east and the south-east trades between the tropics of cancer and capricorn1 and also the counter currents to the north and south of these1 while the arrows around the circle show how counter currents meet and rise1 or descend1 and produce the calm belts4 ,we have hitherto enlarged chiefly on the grand currents of the atmosphere1 and on those modifying causes and effects which are perpetual4 ,let us now turn to the consideration of those winds which are produced by local causes1 and the effects of which are partial4 ,and here we are induced to revert to the ,gulf ,stream1 which has been already referred to as a local disturber of the regular flow of the atmosphere4 ,this immense body of heated water1 passing through cold regions of the sea1 has the effect of causing the most violent storms4 ,the hurricanes of the ,west ,indies are among the most violent in the world4 ,we have read of one so violent that it forced the ,gulf ,stream back to its sources1 and piled up the water in the ,gulf to the height of thirty feet4 ,a vessel named the ,ledbnry ,snow attempted to ride it out4 ,when it abated1 she found herself high up on the dry land1 having let go her anchor among the tree-tops of ,elliott's quay6 ,the ,florida quays were inundated many feet2 and it is said the scene presented in the ,gulf ,stream was never surpassed in awful sublimity on the ocean4 ,the water thus dammed up rushed out with frightful velocity against the fury of the gale1 producing a sea that beggared description4 ,the monsoons of the ,indian ,ocean are among the most striking and regular of the locally-caused winds4 ,before touching on their causes1 let us glance at their effects4 ,they blow for nearly six months in one direction1 and for the other six in the opposite direction4 ,at the period of their changing1 terrific gales are frequent--gales such as we1 in our temperate regions1 never dream of4 ,what is termed the rainy season in ,india is the result of the south-west monsoon1 which for four months in the year deluges the regions within its influence with rain4 ,the commencement of the south-west monsoon is described as being sublime and awful beyond description4 ,before it comes1 the whole country is pining under the influence of long-continued drought and heat2 the ground is parched and rent2 scarcely a blade of verdure is to be seen except in the beds of rivers1 where the last pools of water seem about to evaporate1 and leave the land under the dominion of perpetual sterility4 ,man and beast pant for fresh air and cool water2 but no cool breeze comes4 ,a blast1 as if from the mouth of a furnace1 greets the burning cheek2 no blessed drops descend2 the sky is clear as a mirror1 without a single cloud to mitigate the intensity of the sun's withering rays4 ,at last1 on some happy morning1 small clouds are seen on the horizon4 ,they may be no bigger than a man's hand1 but they are blessed harbingers of rain4 ,to those who know not what is coming1 there seems at first no improvement on the previous sultry calms4 ,there is a sense of suffocating heat in the atmosphere2 a thin haze creeps over the sky1 but it scarcely affects the broad glare of the sun4 ,at length the sky begins to change4 ,the horizon becomes black4 ,great masses of dark clouds rise out of the sea4 ,fitful gusts of wind begin to blow1 and as suddenly to cease2 and these signs of coming tempest keep dallying with each other1 as if to tantalise the expectant creation4 ,the lower part of the sky becomes deep red1 the gathering clouds spread over the heavens1 and a deep gloom is cast upon the earth and sea4 ,and now the storm breaks forth4 ,the violent gusts swell into a continuous1 furious gale4 ,rain falls1 not in drops1 but in broad sheets4 ,the black sea is crested with white foam1 which is quickly swept up and mingled with the waters above2 while those below heave up their billows1 and rage and roar in unison with the tempest4 ,on the land everything seems about to be uprooted and hurled to destruction4 ,the tall straight cocoa-nut trees are bent over till they almost lie along the ground2 the sand and dry earth are whirled up in eddying clouds1 and everything movable is torn up and swept away4 ,to add to the dire uproar1 thunder now peals from the skies in loud1 continuous roars1 and in sharp angry crashes1 while lightning plays about in broad sheets all over the sky1 the one following so close on the other as to give the impression of perpetual flashes and an unintermitting roar2 the whole scene presenting an aspect so awful1 that sinful man might well suppose the season of the ,earth's probation had passed away1 and that the ,almighty were about to hurl complete destruction upon his offending creatures4 ,but far other intentions are in the breast of ,him who rides upon the storm4 ,his object is to restore1 not to destroy--to gladden1 not to terrify4 ,this tempestuous weather lasts for some days1 but at the end of that time the change that comes over the face of nature seems little short of miraculous4 ,in the words of ,mr ,elphinstone1 who describes from personal observation--,the whole earth is covered with a sudden but luxuriant verdure1 the rivers are full and tranquil1 the air is pure and delicious1 and the sky is varied and embellished with clouds4 ,the effect of this change is visible on all the animal creation1 and can only be imagined in ,europe by supposing the depth of a dreary winter to start at once into all the freshness and brilliancy of spring4 ,from that time the rain falls at intervals for about a month1 when it comes on again with great violence2 and in ,july the rains are at their height4 ,during the third month they rather diminish1 but are still heavy4 ,in ,september they gradually abate1 and are often suspended till near the end of the month1 when they depart amid thunders and tempests1 as they came4 ,such are the effects of the monsoons upon land and sea4 ,of course the terrific gales that usher them in and out could not be expected to pass without doing a good deal of damage1 especially to shipping4 ,but this is more than compensated by the facilities which they afford to navigation4 ,in many parts of the world1 especially in the ,indian ,ocean1 merchants calculate with certainty on these periodical winds4 ,they despatch their ships with1 say1 the north-east monsoon1 transact business in distant lands1 and receive them back1 laden with foreign produce1 by the south-west monsoon4 ,if there were no monsoons1 the voyage from ,canton to ,england could not be accomplished in nearly so short a time as it is at present4 ,and now as to the cause of monsoons4 ,they are1 for the most part1 deflected trade-winds4 ,and they owe their deflection to the presence of large continents4 ,if there were no land near the equator1 the trade-winds would always blow in the same manner right round the world2 but the great continents1 with their intensely-heated surfaces1 cause local disturbance of the trade-winds4 ,when a trade-wind is turned out of its course1 it is regarded as a monsoon4 ,for instance1 the summer sun1 beating on the interior plains of ,asia1 creates such intense heat in the atmosphere that it is more than sufficient to neutralise the forces which cause the trade-winds to blow4 ,they are1 accordingly1 arrested and turned back4 ,the great general law of the trades is in this region temporarily suspended1 and the monsoons are created4 ,it is thus that the heated plains of ,africa and ,central ,america produce the monsoons of the ,atlantic1 the ,pacific1 and the ,gulf of ,mexico4 ,we think it unnecessary to explain minutely the causes that produce variation in the monsoons4 ,every intelligent reader will readily conceive how the change of seasons and varied configuration as well as unequal arrangement of land and water1 will reverse1 alter1 and modify the direction and strength of the monsoons4 ,land and sea breezes are the next species of wind to which we would direct attention4 ,they occur in tropical countries1 and owe their existence to the fact that the land is much more easily affected by sudden changes of temperature than the sea4 ,thus1 the land in warm regions is much heated by the sun's rays during the day2 the atmosphere over it becomes also heated1 in virtue of which it rises3 the cool atmosphere over the sea rushes in to supply its place1 and forms the sea breeze3 which occurs only during the day4 ,at night the converse of this takes place4 ,land heats and cools rapidly2 water heats and cools slowly4 ,after the sun sets1 the cooling of the land goes on faster than that of the sea4 ,in a short time the atmosphere over the land becomes cooler than that over the sea2 it descends and flows off out to sea2 thus forming the land breeze4 ,it occurs only at night1 and when the change from one to the other is taking place there is always a short period of calm4 ,land and sea breezes are of the greatest use in refreshing those regions which1 without them1 would be almost1 if not altogether1 uninhabitable4 ,in ,the ,tempest1 an interesting work on the origin and phenomena of wind1 published by the ,society for ,promoting ,christian ,knowledge1 a curious and simple experiment is described1 whereby the existence of upper and under currents of air and the action of land and sea breezes may be clearly seen and understood4 ,we quote the passage3-- ,the existence of the upper and under currents of air which mark the phenomena of the trade-winds1 and of land and sea breezes1 may be beautifully illustrated in two adjoining rooms1 in one of which a good fire is burning1 while in the other there is none4 ,if the door between the two rooms be thrown open1 the cold air will enter the heated room in a strong current1 or1 in other words1 as a violent wind4 ,at the same time the heated air of the warm room ascends and passes the contrary way into the cold room1 at the upper part of the same doorway2 while in the middle of this opening1 exactly between the two currents1 the air appears to have little or no motion4 ,the best way to show this experiment is to introduce the flame of a candle into the doorway between a hot and a cold room4 ,if the flame be held near the bottom of the doorway1 where the air is most dense1 it will be strongly drawn towards the heated room2 and if held near the top of the door it will be drawn towards the cold room with somewhat less force2 while midway between the top and bottom the flame will be scarcely disturbed4 ,there is also another pretty experiment which illustrates well the theory of land and sea breezes4 ,take a large dish1 fill it with cold water1 and in the middle of this put a water-plate or a saucer filled with warm water4 ,the first will represent the ocean1 and the latter an island made hot by the rays of the sun1 and rarefying the air above it4 ,take a lighted wax candle and blow it out2 and1 if the air of the room be still1 on applying it successively to every side of the saucer1 the smoke will be seen moving towards the saucer and rising over it1 thus indicating the course of the air from sea to land4 ,on reversing the experiment1 by filling the saucer with cold water 7to represent the island at night7 and the dish with warm water1 the land breeze will be shown by holding the smoking wick over the edge of the saucer2 the smoke will then be wafted to the warmer air over the dish4 ,we have just tried the first of these experiments1 with complete success4 ,we would1 however1 recommend a piece of twisted brown paper1 lighted and blown out1 instead of a wax candle1 because it gives out more smoke and is probably more obtainable on short notice4 ,the experiment of the doorway1 moreover1 does not require that there should lie two rooms with a door between4 ,we have found that the door of our study1 which opens into a cold passage1 serves the purpose admirably4 ,were we treating chiefly of the atmosphere in this work1 it would be necessary that we should enlarge on all the varieties of winds1 with their causes1 effects1 and numerous modifications4 ,but our main subject is the ,ocean4 ,the atmosphere1 although it could not with justice have been altogether passed over1 must hold a secondary place here2 therefore we will conclude our remarks on it with a brief reference to hurricanes4 ,it has been ascertained that most of the great storms that sweep with devastating fury over the land and sea are not1 as was supposed1 rectilinear in their motion1 but circular4 ,they are1 in fact1 enormous whirlwinds1 sometimes upwards of one hundred and fifty miles in diameter2 and they not only whirl round their own centres1 but advance steadily forward through space4 ,in the year #ahca1 a memorable and dreadful series of storms passed over some of the ,india ,islands1 and caused terrible havoc1 especially in the island of ,barbadoes4 ,the peculiarity of these hurricanes was that they ravaged the different islands at different dates1 and were therefore supposed to be different storms4 ,such1 however1 was not the case4 ,it was one mighty cyclone1 or circular storm1--a gigantic whirlwind1--which traversed that region at the rate of about sixteen miles an hour4 ,it was not its progressive1 but its rotatory motion1 that constituted its terrible power4 ,on the #ajth of ,august it reached ,barbadoes2 on the #aath1 the islands of ,saint ,vincent and ,saint ,lucia2 on the #abth it touched the southern coast of ,porto ,rico2 on the #acth it swept over part of ,cuba2 on the #adth it encountered ,havanna2 on the #agth it reached the northern shores of the ,gulf of ,mexico and travelled on to ,new ,orleans1 where it raged till the #ahth4 ,it thus1 in six days1 passed1 as a whirlwind of destruction1 over two thousand three hundred miles of land and sea4 ,it was finally dissipated amid heavy rains4 ,the effect of a hurricane is well described by ,washington ,irving4 ,about mid-day1 he says1 a furious gale sprang up from the east1 driving before it dense volumes of cloud and vapour4 ,encountering another tempest from the west1 it appeared as if a violent conflict ensued4 ,the clouds were rent by incessant flashes1 or rather streams1 of lightning4 ,at one time they were piled up high in the sky1 at another they descended to the earth1 filling the air with a baleful darkness1 more impenetrable than the obscurity of midnight4 ,wherever the hurricane passed1 whole tracts of forest were shivered and stripped of their leaves and branches2 and trees of gigantic size1 which resisted the blast1 were torn up by the roots and hurled to a great distance4 ,groves were torn from the mountain-precipices1 and vast masses of earth and rock precipitated into the valleys with terrific noise1 choking the course of the rivers4 ,the fearful sounds in the air and on the earth1 the pealing thunder1 the vivid lightning1 the howling of the wind1 the crash of falling trees and rocks1 filled every one with affright1 and many thought that the end of the world was at hand4 ,some fled to caverns for safety1 for their frail houses were blown down1 and the air was filled with the trunks and branches of trees1 and even with fragments of rocks1 carried along by the fury of the tempest4 ,when the hurricane reached the harbour1 it whirled the ships round as they lay at anchor1 snapped their cables1 and sunk three of them to the bottom with all who were on board4 ,others were driven about1 dashed against each other1 and tossed mere wrecks upon the shore by the swelling surges of the sea1 which in some places rolled for three or four miles upon the land4 ,this tempest lasted for three hours4 ,the ,china seas are the most frequently visited by severe tempests1 or typhoons2 yet of all vessels1 the ,chinese junks1 as they are called1 seem to be least adapted by their build for encountering such storms4 ,a terrible hurricane burst upon the ,china seas in the month of ,january #ahcg1 as we learn from the ,united ,service ,journal of that year4 ,an ,english vessel was exposed to it4 ,the sea1 rising in mountains around and over the ship's sides1 hurled her rapidly on her passage homeward1 when suddenly a wreck was discovered to the westward4 ,the order to shorten sail was given1 and promptly obeyed2 and when they neared the wreck they found her to be a ,chinese junk without mast or rudder--a helpless log on the breast of that boiling sea4 ,there were many ,chinamen on deck vehemently imploring assistance4 ,the exhibition of their joy on beholding the approach of the stranger was of the wildest and most extravagant nature2 but it was doomed to be suddenly turned to despair1 as the violence of the storm drove the ship past the wreck4 ,it became necessary to put her on the other tack1 a manoeuvre which the poor creatures construed into abandonment1 and the air rang with the most agonising shrieks of misery4 ,but hope was again raised1 when a boat was lowered and a rope thrown on board for the purpose of towing the junk to the ship4 ,this intention was frustrated by the windlass breaking4 ,at sight of this one man1 in a paroxysm of despair1 jumped overboard after the rope2 but he missed it4 ,being a good swimmer1 he tried to reach the boat2 but his feeble power could avail him nothing in the midst of such raging elements3 he speedily sank to rise no more4 ,another rope1 however1 was secured to the junk1 and by means of it the rest of the crew 7eighteen in number7 were saved4 ,their gratitude was boundless4 ,they almost worshipped the officers1 the crew1 and the vessel1 prostrating themselves and kissing the feet of the former1 and the very planks of the latter4 ,well-built ships1 however1 are not always able to withstand the violence of rotatory storms4 ,instances occur in which the tightest built and best manned ships are destroyed as suddenly as the clumsiest of ill-managed junks4 ,not many years ago1 a vessel was proceeding prosperously on her voyage1 when signs of a coming tempest induced the wary captain to reduce1 and1 finally1 to take in all sail4 ,but his precautions were in vain4 ,the storm burst on the devoted ship1 and in a few minutes the masts went over the side1 and the hull lay a total wreck upon the sea4 ,these hurricanes or cyclones1 although in reality whirlwinds1 are so large that man's eye cannot measure them1 and it is only by scientific investigation that we have arrived at the knowledge of the fact4 ,the whirlwind1 properly so called1 is a much smaller body of atmosphere4 ,sometimes we see miniature whirlwinds1 even in our own temperate land1 passing along a road in autumn1 lifting the leaves and dust into the air and carrying them along in the form of a rotatory pillar4 ,in other regions they exert a power quite equal to the tempest1 though in a more limited space1 overturning houses1 uprooting trees1 cutting a track twenty or thirty yards wide through the dense forest as thoroughly as if a thousand woodmen had been at work there for many years4 ,when whirlwinds pass from the land to the sea they create waterspouts2 of which we shall have something to say in another chapter4 ,meanwhile1 we think it may be interesting to give the following miscellaneous information regarding the atmosphere1 gathered from the work of ,dr ,buist1 who devoted much earnest study to the subject of atmospheric phenomena4 ,the weight of the atmosphere is equal to that of a solid globe of lead sixty miles in diameter4 ,its principal elements are oxygen and nitrogen gases1 with a vast quantity of water suspended in them in the shape of vapour2 and1 commingled with these1 a quantity of carbon in the shape of fixed air1 sufficient to restore from its mass many-fold the coal that now exists in the world4 ,water is not compressible or elastic2 it may be solidified into ice or vaporised into steam3 but the air is elastic and compressible4 ,it may be condensed to any extent by pressure1 or expanded to an infinite degree of tenuity by pressure being removed from it4 ,it is not liable to undergo any changes in constitution beyond these1 by any of the ordinary influences by which it is affected4 ,if the heating and cooling process--which we have described as being carried on between the equator and the poles--were to cease1 we should have a furious hurricane rushing perpetually round the globe at the rate of one thousand miles an hour1--ten times the speed of the most violent tornado that has ever carried devastation over the surface of the earth4 ,the air1 heated and dried as it sweeps over the arid surface of the soil1 drinks up by day myriads of tons of moisture from the sea1--so much1 indeed1 that1 were none restored to it1 the surface of the ocean would be depressed eight or ten feet annually4 ,we do not certainly know the height of the atmosphere4 ,it is said that its upper surface cannot lie nearer to us than fifty1 and can scarcely be further off than five hundred1 miles4 ,it surrounds us on all sides1 yet we cannot see it2 it presses on us with a weight of fifteen pounds on every square inch of the surface of our bodies--in other words1 we are at all times sustaining a load of between seventy and one hundred tons of it on our persons--yet we do not feel it6 ,softer than the finest down1 more impalpable than the lightest gossamer1 it leaves the cobweb undisturbed1 and1 at times1 scarcely stirs the most delicate flower that feeds on the dew it supplies2 yet it bears the fleets of nations on its wings round the world1 and crushes the most refractory substances with its weight4 ,it bends the rays of the sun from their path to give us the aurora of the morning and the twilight of evening4 ,it disperses and refracts their various tints to beautify the approach and the retreat of the orb of day4 ,but for the atmosphere1 sunshine would burst on us in a moment and fail us in the twinkling of an eye1 removing us in an instant from midnight darkness to the blaze of noon4 ,we have written a good deal on this subject1 yet the thousandth part has not been told of even the grand and more obvious operations of the atmosphere1 much less the actions and results of its minor and invisible processes4 ,were we to descend with philosophers into the minuter laboratories of the world1 and consider the permeating1 ramifying1 subtle part the atmosphere plays in the innumerable transformations that are perpetually going on around and within us1 we should be constrained to feel more deeply than we have ever yet felt1 that the works of the ,creator are indeed wonderful beyond all expression or conception4 ,,chapter ,,seven4 ,,waterspouts--,,causes ,,of--,,appearance--,,electricity--,,exp eriments--,,artificial ,,waterspouts--,,showers ,,of ,,fish--,,mr4 ,,ellis ,,on ,,waterspouts ,,in ,,the ,,south ,,seas4 ,we turn back now from the atmospheric to the aqueous ocean4 ,yet so intimate is the connection between the two1 that we shall find it impossible to avoid occasional reference to the former4 ,our present subject1 waterspouts1 obliges us to recur for a little to the atmosphere1 which we dismissed1 or attempted to dismiss1 in the last chapter4 ,there is no doubt that waterspouts are to a great extent1 if not altogether1 due to the presence of electricity in the air4 ,when the clouds have been raging for some time in the skies of tropical regions1 rendering the darkness bright1 and the air tremulous with their dread artillery1 they seem to grow unusually thirsty2 the ordinary means of water-supply through the atmosphere do not appear to be sufficient for the demand1 or war-tax in the shape of water-spouts1 that is levied on nature4 ,the clouds therefore descend to the sea1 and1 putting down their dark tongues1 lick up the water thirstily in the form of waterspouts4 ,these whirling pillars of water frequently appear in groups of several at a time4 ,they are of various heights1 sometimes ranging up to seven hundred yards1 with a thickness of fifty yards1 and are very dangerous to ships that happen to come within their influence4 ,that they are caused by electricity has been proved by experiment-- miniature waterspouts have been produced by artificial means2 and as ,dr ,bonzano of ,new ,york gives particular directions how the thing ought to be done1 we quote his words for the benefit of those who happen to possess electrical machines4 ,from the conductor of an electrical machine suspend1 by a wire or chain1 a small metallic ball 7one of wood covered with tinfoil72 and under the ball place a rather wide metallic basin1 containing some oil of turpentine1 at the distance of about three-quarters of an inch4 ,if the handle of the machine be now turned slowly1 the liquid in the basin will begin to move in different directions and form whirlpools4 ,as the electricity on the conductor accumulates1 the troubled liquid will elevate itself in the centre1 and at last become attached to the ball4 ,draw off the electricity from the conductor1 to let the liquid resume its position2 a portion of the turpentine remains attached to the ball4 ,turn the handle again very slowly1 and observe now the few drops adhering to the ball assume a conical shape1 with the apex downward2 while the liquid under it assumes also a conical shape1 the apex upward1 until both meet4 ,as the liquid does not accumulate on the ball1 there must necessarily be as great a current downward as upward1 giving the column of liquid a rapid circular motion1 which continues until the electricity from the conductor is nearly all discharged silently1 or until it is discharged by a spark descending into the liquid4 ,the same phenomena take place with oil or water4 ,using the latter liquid1 the ball must be brought much nearer1 or a much greater quantity of electricity is necessary to raise it4 ,if1 in this experiment1 we let the ball swing to and fro1 the little waterspout will travel over its immature sea1 carrying its whirlpools along with it4 ,when it breaks up1 a portion of the liquid--and with it anything it may contain--remains attached to the ball4 ,the fish1 seeds1 leaves1 etcetera1 that have fallen to the earth in rain-squalls1 may have owed their elevation to the clouds to the same cause that attaches a few drops of the liquid1 with its particles of impurities1 to the ball4 ,there can be no doubt whatever that fish are carried up in waterspouts1 because the descent of those creatures from the skies in rain is a well-established fact2 and if they did not get there in waterspouts-- which1 when we consider it1 seems most natural--then we are driven to the conclusion that their native region is the sky1 which is by no means so natural or so probable4 ,many travellers have recorded the fact that small fish have descended in rain4 ,in a letter written not long ago by a gentleman in ,singapore we have the following account of a shower of fish3-- ,we experienced a shock of earthquake here on the #afth ,february last4 ,its duration was about two minutes4 ,although it caused no damage1 its undulatory motion was sufficiently strong to affect certain persons with a sensation akin to sea-sickness4 ,it was followed by rain in torrents1 on the #bjth1 #bast1 and #bbnd4 ,on the latter day especially1 we were1 for half an hour1 surrounded with water to a considerable depth4 ,we could not see three yards before us4 ,when the sun came out again1 ,i saw a number of ,malays and ,chinese filling their baskets with fish contained in the pools formed by the rain4 ,they told me the fish had fallen from heaven1' and three days later1 when the pools were all dried up1 there were still many dead fish lying about4 ,as they lay in my court-yard1 which is surrounded by a wall1 they could not have been brought in by the overflowing of a torrent2 indeed1 there is none of any considerable size in the neighbourhood4 ,the space covered by these fish might be about fifty acres1 comprising the eastern part of the town4 ,they were very lively1 and seemed to be in good health4 ,the writer of the above suggests1 with some degree of hesitation1 that these fish were sucked up by waterspouts4 ,we think that there need be no hesitation in the matter6 ,the appearance usually presented by a waterspout is that of a column of aqueous vapour reaching from the sea to the clouds1 sometimes straight1 more frequently a little bent1 and thicker above and below than in the centre of the column4 ,mr ,ellis1 the missionary1 in his ,polynesian ,researches1 mentions having1 with a companion1 met and narrowly escaped being overwhelmed by several waterspouts1 when passing on one occasion in an open boat between two islands about thirty miles apart4 ,on the passage they were overtaken by a sudden and violent squall1 which lasted several hours2 and1 in order to avoid being sunk1 they tied their masts1 oars1 and sails in a bundle1 and attaching a rope to them1 and to the boat1 cast them into the sea4 ,thus they lay1 as it were1 at anchor in the lee of this extemporised breakwater4 ,it was but a feeble barrier1 however1 against so wild a storm1 and the native boatmen were so overcome by fear1 that they sat down in the bottom of the boat1 and covered their eyes with their hands4 ,after a time the rain diminished1 the sky began to clear1 and the boat's crew to revive1 when suddenly one of the men uttered a cry of consternation1 and pointed to an object towards which all eyes were instantly turned4 ,they beheld a large cylindrical waterspout1 extending1 like a massive column1 from the ocean to the dark and impending clouds4 ,it was not far distant1 and seemed to move slowly towards the boat4 ,had ,mr ,ellis had any doubt as to the danger of a waterspout1 the extreme terror exhibited by the natives on this occasion must have removed it2 for it was not probable that1 just after escaping from the most imminent peril1 they would fail back into a much more violent state of terror1 unless former experience had given them too good reason to dread the presence of the object they now saw before them4 ,the roughness of the sea forbade their attempting to hoist a sail in order to avoid the waterspout4 ,they were compelled1 therefore1 to summon all the resolution they possessed1 to enable them calmly to await its approach1 and put their trust in the arm of ,jehovah4 ,the helm was in the hands of a seaman whose steadiness could be depended on4 ,the natives were down in the bottom of the boat2 they had given way to despair4 ,two other waterspouts now came into view1 and subsequently a third1 if not more1 so that they felt as if completely surrounded by them4 ,some were well defined1 extending in an unbroken line from the sea to the sky1 like pillars resting on the ocean as their basis1 and supporting the clouds2 others1 assuming the shape of a funnel or inverted cone attached to the clouds1 extended their sharp points to the ocean below4 ,from the distinctness with which they were seen1 it was judged that the furthest could not have been many miles distant4 ,in some they imagined they could trace the spiral motion of the water as it was drawn up to the clouds1 which were every moment being augmented in their portentous darkness4 ,the sense of personal danger1 ,mr ,ellis confesses1 and the certainty of instant destruction if brought within their vortex1 prevented a very careful observation of their appearance and accompanying phenomena4 ,the storm continued all day1 and at intervals the party in the boat beheld1 through the driving clouds and rain1 one or other of those towering waterspouts2 which1 however1 did not come nearer to them4 ,it is interesting to read the record left by a ,christian missionary of his conflicting feelings on that terrible occasion4 ,mr ,ellis believed that all hope of escape was over1 and his mind went through that ordeal which must be the experience of every one who sees the steady approach of speedy death4 ,he says that during those hours when he sat awaiting his doom1 the thought of death itself did not make a deep impression4 ,the struggle1 the gasp1 as the wearied arm should attempt to resist the impetuous waves2 the straining vision1 that should linger on the last ray of retiring light1 as the deepening veil of water would gradually conceal it for ever2 and the rolling billows heaving over the sinking and dying body1 which1 perhaps ere life should be extinct1 might become the prey of voracious inhabitants of the deep2--these things caused scarcely a thought1 compared with the immediate prospect of the disembodied spirit being ushered into the presence of its ,maker2 the account to be rendered1 and the awful and unalterable destiny that would await it there4 ,these momentous objects1 he says1 absorbed all the powers of the mind1 and produced an intensity of feeling1 which1 for a long time1 rendered me almost insensible to the storm1 or the liquid columns which threatened our destruction4 ,it was now that the missionary could look back with deepest gratitude upon that mercy which had first brought him to a knowledge of the ,saviour4 ,him and ,him alone1 he adds1 ,i found to be a refuge1 a rock in the storm of contending feelings1 on which my soul could cast the anchor of its hope for pardon and acceptance before ,god444 ,i could not but think how awful would have been my state1 had ,i in that hour been ignorant of ,christ1 or had ,i neglected or despised the offers of his mercy4 ,our prayers were offered to ,him who is a present help in every time of danger1 for ourselves and those who sailed with us2 and under these and similar exercises several hours passed away4 ,those prayers were answered1 for the waterspouts gradually disappeared1 and the boat got safe to land4 ,in speaking of another waterspout1 seen on a subsequent voyage1 ,mr ,ellis tells us that it was well defined1--an unbroken column from the sea to the clouds1 which on this occasion were neither dense nor lowering4 ,around the outside of the liquid cylinder was a kind of thick mist2 and within1 a substance resembling steam1 ascending apparently with a spiral motion4 ,the water at its base was considerably agitated with a whirling motion2 while the spray which was thrown off from the circle formed by the lower part of the column1 rose several feet above the level of the sea4 ,it passed about a mile astern of the ship4 ,occasionally1 when passing nearer to a ship than was deemed safe1 a waterspout has been dissipated by a cannon-shot1 as represented in our engraving4 ,such are the usual appearances and actions of waterspouts4 ,they are not1 however1 properly named1 being simply whirlwinds at sea1 instead of whirlwinds on land4 ,professor ,oersted suggests the name storm-pillar1 as being a more appropriate term4 ,it does not follow that a large ship would inevitably be destroyed if brought within the vortex of a waterspout2 but it is certain that she would run the risk of being dismasted1 and perhaps thrown on her beam-ends4 ,navigators have not had sufficient experience of the power of waterspouts to pronounce authoritatively on that point1--and it is to be hoped they never will4 ,captain ,beechy1 in his narrative of a voyage to the ,pacific1 describes one into which his ship actually entered1 and from which he received extremely rough handling before he was set free4 ,but this might not have been a very large waterspout2 and it is not absolutely certain whether he was quite within its vortex1 or was merely brushed by the skirts of its outer garment4 ,certain it is that waterspouts vary in size and in power2 for we read of them passing from the sea to the land1 and there rooting up trees1 unroofing and overturning houses1 dismounting cannon1 emptying fish ponds1 half emptying harbours1 and otherwise exhibiting a degree of force that would undoubtedly sink the largest vessel that ever was built1 if brought thoroughly to bear upon it4 ,the rate of motion in waterspouts varies4 ,sometimes they revolve slowly1 sometimes with the utmost rapidity4 ,they often produce violent noise1 as1 indeed1 might be expected2 and they are generally accompanied by thunder and lightning1 though not invariably so1 for they are sometimes observed when the heavens are clear and the sea calm4 ,,chapter ,,eight4 ,,the ,,arctic ,,seas--,,their ,,character1 ,,scenery1 ,,and ,,atmospherical ,,illusions4 ,there is a tendency on the part of most writers on the subject of ,polar ,regions--especially compilers--to dwell disproportionately on the gloomy side of the picture2 insomuch that readers are led1 not to over-estimate the grand and the terrible aspects of the polar oceans1 but to under-estimate the sweet and the beautiful influences that at certain periods reign there4 ,we quarrel not with authors for dwelling on the tremendous and the awful4 ,too much cannot be said on these points2 but while they do not by any means paint the dark side of their picture too black1 they fail to touch in the lights with sufficient brilliancy4 ,we have had some personal experience of the arctic regions1 and have found it extremely difficult to get many persons--even educated men and women--to understand that there is a summer there1 though a short one2 that in many places it is an uncommonly hot and excessively brilliant summer2 and that the sun1 as if to make amends for its prolonged absence in winter1 shines all night as well as all day1 blazing on the crystal icebergs and pure snow 7which never disappear from those seas7 with a degree of splendour that renders the far north transcendently beautiful and pre-eminently attractive4 ,we admit freely that the prevailing character of arctic seas1 during the greater part of the year1 is dark1 gloomy1 forbidding4 ,but this is the very reason why their brief but cheering smiles should be brought prominently into the foreground1 and1 if they cannot in justice be dwelt on long1 at least be touched upon with emphasis4 ,why1 in some of our cyclopaedia accounts of the realms of thick-ribbed ice1 so much prominence is given to the horrors and wide desolation of the scene1 and so much graphic power is expended in working up the reader's imagination to a conception of the dreadful dangers and the appalling terrors that await the madman who should dare to venture within the arctic circle1 that persons who have not been there might well be tempted to shrink in affright from the very contemplation of a region in which there does not appear to be one redeeming quality4 ,we repeat1 that we do not think the one side of the picture has been too darkly painted1--but the other side has been painted too slightly4 ,at the same time1 we would caution our readers against jumping to the opposite extreme4 ,the dark side of the picture is in reality out of all proportion to the light4 ,and we do not hesitate to state our confirmed opinion1 that the arctic regions are more interesting to read about than pleasant to dwell in4 ,having1 then1 defended the lights1 let us commence our investigations with the shadows4 ,those oceans lying within the arctic circle exhibit phenomena so grand1 so wonderful1 and so varied1 that they claim distinct and separate treatment from the ocean as a whole4 ,here the extreme cold acts with such power1 and produces such extraordinary results1 that it is difficult to find words or similes by which to convey a just conception of nature's aspects to the general reader4 ,during nearly two-thirds of the year the arctic regions are under the absolute dominion of winter2 and for many weeks of that bitter season they are shrouded with the mantle of a dark1 sunless night4 ,the entire ocean is locked in the embrace of a covering of ice many feet thick1 so that its liquid aspect is thoroughly removed2 and1 owing to ice-masses scattered over its surface1 together with mounds of drifted snow1 it bears a much stronger resemblance to the land than to the sea4 ,gales of wind sometimes sweep over those frozen plains in bitter fury1 hurling the snow into the air in vast eddying masses1 and threatening destruction to any living creature that may chance to be exposed to them--not so much from their violence1 however1 as from the intense cold of the atmosphere which is put in motion4 ,but in regard to gales1 although there are no lack of them1 they are neither so fierce nor so frequent as are those of the torrid zone4 ,it might be supposed that in such a climate animal life could scarcely exist2 but such is not the case4 ,the inhabitants of part of the arctic regions1 named ,esquimaux 7more correctly ,eskimos1 with the accent on the last syllable71 are a stout1 hardy1 healthy race and the polar bears1 foxes1 wolves1 seals1 musk-oxen1 walruses1 etcetera1 that dwell there1 seem to enjoy their existence just as much as do the animals of more favoured and warmer climes4 ,during the short but hot summer of the arctic regions1 the immense masses of ice formed in winter are by no means cleared away4 ,a great part of the heat of early summer 7there is no season there that merits the name of spring7 is spent in breaking up the solid crust of ice on the sea1 a large proportion of which is carried south by the currents that flow to the equator1 and melted long before they reach the temperate zones4 ,but a considerable quantity of broken ice-masses get locked in narrow places or stranded on shallows2 and although they undergo the process of melting the whole summer1 they are not much diminished ere the returning frost stops the process and locks them in the new ice of a succeeding winter4 ,thus there is no period of the year in which large quantities of ice may not be seen floating about in the arctic seas4 ,this fact it is that enables us to speak appropriately of the scenery of the ,arctic ,ocean4 ,and assuredly this scenery of the ice is exceedingly and strikingly beautiful4 ,the imagination cannot conceive the dazzling effect of a bright summer day in those regions1 when the ocean is clear as glass1 and ice-humps and ice-mountains of every shape and size are glittering in the sun's rays with intense brilliancy1 while the delicate whiteness of these floating islands1 and the magical atmospheric illusions by which they are frequently surrounded1 render the scene pre-eminently fairy-like4 ,all the navigators who have penetrated into the arctic seas speak with enthusiasm of the splendour of floating ice-masses4 ,they take the most curious and fantastic shapes2 sometimes appearing like great cities of white marble1 with domes and towers and spires in profusion2 sometimes looming huge and grand like fortresses1 and many of them with their summits overhanging so much as to suggest the idea that they are about to fall4 ,this indeed1 they often do1 adding to the grandeur of the scene1 and not a little to the danger1 should ships chance to be in the neighbourhood4 ,the atmospheric illusions1 before mentioned1 are the result of different temperatures existing within a few miles of each other1 and which are caused by the presence of large bodies of ice4 ,the effect of this is to cause the ice-masses on the horizon to appear as if floating in the air1 and to distort them into all sorts of shapes1 even turning them upside down1 and thus affording to an innovative mind a most ample and attractive field wherein to expatiate4 ,to ascertain the causes of facts and effects so curious must be interesting to all who have inquiring minds4 ,we will1 therefore1 attempt to describe and account for arctic phenomena in the following chapters as simply as may be4 ,,chapter ,,nine4 ,,formation ,,of ,,ice--,,dangers ,,of ,,disrupting ,,ice--,,anecdote--,,drifting ,,ice-- ,,drift ,,of ,,the ,,fox--,,nipping ,,anecdote--,,loss ,,of ,,the ,,breadalbane4 ,it is well known that when fresh water becomes so cold that its temperature is #cb degrees of ,fahrenheit's scale1 it loses its liquid form and becomes ice4 ,a somewhat lower temperature than this is necessary to freeze salt water2 the reason being1 that greater force is required to expel the salt which the sea holds in solution1--which salt is always more or less expelled in the process of freezing4 ,ice commences to form in the shape of needles1 which shoot out at angles from each other4 ,in smooth water1 under the influence of intense cold1 the process is rapid1 and a thin cake soon covers the water1 and increases in thickness hour by hour4 ,but when the sea is agitated the process is retarded1 and the fine needles are broken up into what arctic navigators call sludge4 ,this1 however1 soon begins to cake1 and is broken by the swell into small cakes2 which1 as they thicken1 again unite1 and are again broken up into larger masses4 ,these masses1 by rubbing against each other1 have their edges slightly rounded up1 and in this form receive the name of pancake ice4 ,when a quantity of ice covers the ocean in a wide level sheet of considerable extent1 it is called an ice-field4 ,fields of this kind are often seen by navigators hundreds of miles in extent1 and nearly thirty feet thick4 ,ice of such thickness1 however1 only shows five or six feet above water4 ,when fields are broken by heavy ocean-swells1 the edges are violently forced up1 and fall in debris on the surface2 thus hummocks or mounds are formed4 ,when field-ice breaks up under the influence of an ocean-swell1 caused by a storm1 the results are terrific4 ,an exceedingly graphic account of an incident of this kind is given by ,dr ,brown1 in his ,history of the ,propagation of ,christianity4 ,he writes3-- ,the missionaries met a sledge with ,esquimaux1 turning in from the sea1 who threw out some hints that it might be as well for them to return4 ,after some time1 their own ,esquimaux hinted that there was a ground-swell under the ice4 ,it was then scarcely perceptible1 except on lying down and applying the ear close to the ice1 when a hollow1 disagreeable1 grating sound was heard ascending from the abyss4 ,as the motion of the sea under the ice had grown more perceptible1 they became alarmed1 and began to think it prudent to keep close to the shore4 ,the ice also had fissures in many places1 some of which formed chasms of one or two feet2 but as these are not uncommon in ice even in its best state1 and the dogs easily leap over them1 they are frightful only to strangers4 ,as the wind rose to a storm1 the swell had now increased so much that its effects on the ice were extraordinary1 and really alarming4 ,the sledges1 instead of gliding smoothly along as on an even surface1 sometimes ran with violence after the dogs1 and sometimes seemed with difficulty to ascend a rising hill4 ,noises1 too1 like the report of cannon1 were now distinctly heard in many directions1 from the bursting of the ice at a distance4 ,alarmed at these frightful phenomena1 our travellers drove with all haste towards the shore2 and1 as they approached it1 the prospect before them was tremendous4 ,the ice having burst loose from the rocks1 was tossed to and fro1 and broken in a thousand pieces against the precipices with a dreadful noise2 which1 added to the raging of the sea1 the roaring of the wind1 and the driving of the snow1 so overpowered them as almost completely to deprive them of the use of their eyes and ears4 ,to make the land was now the only resource that remained1 but it was with the utmost difficulty that the frightened dogs could be driven forward2 and as the whole body of the ice frequently sank below the summits of the rocks1 and then rose above them1 the only time for landing was the moment it gained the level of the coast--a circumstance which rendered the attempt extremely nice and hazardous4 ,both sledges1 however1 succeeded in gaining the shore1 and were drawn up off the beach1 though not without great difficulty4 ,scarcely had they reached it1 when that part of the ice from which they had just escaped burst asunder1 and the water1 rushing up from beneath1 instantly precipitated it into the ocean4 ,in a moment1 as if by a signal1 the whole mass of ice for several miles along the coast1 and extending as far as the eye could reach1 began to break up1 and to be overwhelmed by the waves4 ,the spectacle was awfully grand4 ,the immense fields of ice rising out of the ocean clashing against each other1 and then plunging into the deep with a violence which no language can describe1 and with a noise like the discharge of a thousand cannon1 was a sight which must have filled the most unreflecting mind with feelings of solemnity4 ,the ,brethren were overwhelmed with amazement at their miraculous escape1 and even the ,esquimaux expressed gratitude to ,god for their deliverance4 ,such is the terrible aspect in which field-ice is seen when broken up and converted into smaller masses or floes4 ,when these lie closely together the mass is called pack-ice2 in which shape it usually drifts away with the southern currents1 and1 separating as it travels south1 is met with in loose floating masses1 of every fantastic form4 ,there is always1 as we have said1 a large quantity of floe and pack-ice in the polar seas1 which becomes incorporated with the new ice of the succeeding winter2 and not infrequently whale and discovery ships get frozen into the pack1 and remain there as firmly embedded as if they lay high and dry on land4 ,when the pack is thus re-frozen1 it usually remains stationary2 but there are occasions and circumstances in which the entire body of a pack drifts slowly southward even during the whole year2 showing clearly that oceanic circulation is by no means arrested by the icy hand of the hyperborean winter4 ,a very remarkable drift of this kind is recorded by ,captain ,mc,clintock of the ,fox1 which is worthy of being noticed here1 as illustrative of the subject we are now considering and also as showing in a remarkable manner the awful dangers to which navigators may be exposed by the disruption of the pack in spring1 and the wonderful1 almost miraculous1 manner in which they are delivered from imminent destruction4 ,in attempting to cross ,baffin's ,bay1 by penetrating what is called the middle ice1 the ,fox was beset1 and finally frozen in for the winter2 and here1 although their voyage may be said to have just commenced1 they were destined to spend many months in helpless inactivity and comparative peril and privation4 ,their little vessel lay in the centre of a field of ice of immense extent2 so large1 indeed1 that they could not venture to undertake a journey to ascertain its limits4 ,yet this field slowly and steadily descended ,baffin's ,bay during the whole winter1 and passed over no fewer than #ache statute miles in the space of #bdb days1 during which period the ,fox was firmly embedded in it6 ,it is with difficulty the mind can form any adequate conception of the position of those voyagers2--unable to move from their icy bed1 yet constantly drifting over miles and miles of ocean2 uncertain as to the where or the when of their deliverance from the pack2 exposed to the terrible dangers of disrupting ice1 and surrounded by the depressing gloom of the long arctic night4 ,at length deliverance came2 but it came surrounded by terrors4 ,in ,february1 ,mc,clintock writes thus3 ,daylight reveals to us evidences of vast ice-movements having taken place during the dark months1 when we fancied all was still and quiet2 and we now see how greatly we have been favoured1 what innumerable chances of destruction we have unconsciously escaped4 ,a few days ago1 the ice suddenly cracked within ten yards of the ship1 and gave her such a smart shock that every one rushed on deck with astonishing alacrity4 ,one of these sudden disruptions occurred between me and the ship1 when ,i was returning from the iceberg4 ,the sun was just setting as ,i found myself cut off444 ,at length ,i reached a place where the jagged edges of the floes met2 so crossed1 and got safely on board4 ,again1 in ,march1 he says1 ,last night the ice closed1 shutting up our lane2 but its opposite sides continued for several hours to move vast each other1 rubbing off all projections1 crushing and forcing out of the water masses four feet thick4 ,although one hundred and twenty yards distant1 this pressure shook the ship and cracked the intervening ice4 ,soon after that1 a heavy gale burst upon them from the south-east1 encircling them with snow-drift so dense that they could neither hear nor see what was going on twenty yards off4 ,at night the ship became suddenly detached from her wintry bed1 and heeled over to the storm1 inducing them to believe that the whole pack had been broken in1 and was pressing against them4 ,this was not the case4 ,a large mass of ice had protected them2 but at a distance of about fifty yards1 ice of four and a half feet thick had been crushed to atoms4 ,soon after1 the protecting mass yielded1 and the ,fox received a nip which lifted her stern about a foot1 while occasional groaning from her sturdy little hull replied to the wild surgings of the ice without4 ,but all this was as nothing compared with the scene of desperate turmoil and confusion which took place when the ice finally broke up1 and a gale raised a fearful swell2 so that the ,fox found herself surrounded by huge masses1 which tossed and ground against each other furiously1 and any two of which pieces could have crushed in her sides as if she had been made of walnut shell4 ,gradually the pack opened out1 and the vessel1 by aid of wind and steam1 was mercifully delivered from her dangerous position4 ,before passing from the subject of risk to navigators to the consideration of other forms and aspects of polar ice1 let us take a glance at an effectual case of nipping4 ,there have been many partial and severe nips1 the descriptions of which are all more or less graphic2 but few ships have come so suddenly to the end of their career as did the ,breadalbane1 a small vessel that was used as a transport ship to the expedition in search of ,sir ,john ,franklin in #aheb4 ,one who was on board when it occurred thus describes it3-- ,sunday1 ,august #bast4--,about ten minutes past four1 the ice passing the ship awoke me1 and the door of my cabin1 from the pressure1 opened4 ,i hurriedly put on my clothes1 and on getting on deck found some hands on the ice endeavouring to save the boats2 but the latter were instantly crushed to pieces4 ,they little thought1 when using their efforts to save the boats1 that the ship was in so perilous a situation4 ,i went forward to hail the ,phoenix 7another ship that was fortunately near7 for men to save the boats2 and whilst doing so1 the ropes by which we were secured parted1 and a heavy nip took us1 making every timber creak1 and the ship tremble all over4 ,i looked in the main hold1 and saw the beams giving way4 ,i hailed those on the ice1 and told them of our critical situation1 they not for one moment suspecting it4 ,i then rushed to my cabin1 hauled out my portmanteau on deck1 and roared like a bull to those in their beds to jump out and save their lives4 ,the startling effect on them might be more easily imagined than described4 ,on reaching the deck1 those on the ice called out to me to jump over the side1 that the ship was going over4 ,i left my portmanteau1 and jumped over the side on the loose ice1 and with difficulty1 and with the assistance of those on the ice1 succeeded in getting on the unbroken part1 with the loss of the slippers ,i had on when quitting the vessel1 with wet feet1 etcetera4 ,the cold was little thought of at the exciting moment--life1 not property1 being the object to be saved4 ,after being on the ice about five minutes1 the timbers1 etcetera1 in the ship cracking up as matches would in the hand1 it eased for a short time2 and ,i1 with some others1 returned to the ship1 with the view of saving some of our effects4 ,captain ,inglefield now came running towards the ship1 and ordered me to see if the ice was through it4 ,on looking down into the hold1 ,i saw all the beams1 etcetera1 falling about in a manner that would have been certain death to me had ,i ventured down there4 ,but there was no occasion for that 7,i mean to ascertain the fact of the ice being through71 it being too evident that the ship could not last many minutes4 ,i then sounded the well1 and found five feet in the hold2 and1 whilst in the act of sounding1 a heavier nip than before pressed out the starboard bow1 and the ice was forced right into the forecastle4 ,every one then abandoned the ship1 with what few clothes they saved--some with only what they had on4 ,the ship now began to sink fast1 and from the time her bowsprit touched the ice until her mast-heads were out of sight1 did not occupy above one minute and a half6 ,it was a very sad and unceremonious way of being turned out of our ship4 ,from the time the first nip took her1 until her disappearance1 did not occupy more than fifteen minutes4 ,such is the account of the fate of the ,breadalbane4 ,while we read it1 we cannot help feeling that many arctic ships must have perished in a similar manner4 ,it is wonderful1 nevertheless1 how many of those that dare the dangers of the ice survive the conflict4 ,undoubtedly this is owing1 to a large extent1 to the fact that ships' bottoms are rounded2 so that when a severe nip takes place1 there is a tendency in the ice to slip under their rounded bottoms1 and squeeze the vessels up out of the water4 ,were it not for this1 few ships that have gone to those seas would ever have returned4 ,a catastrophe such as that which befell the ,breadalbane shows the immense power of field-ice4 ,hundreds of somewhat similar incidents might be cited to illustrate this power2 but we content ourselves with the selection of one instance1 which exhibits it in a remarkable manner1 and at the same time shows the way in which heavy vessels are sometimes forced out of the water4 ,in the year #ahcf1 ,captain ,back commanded the ,terror1 which was sent out to make geographical discoveries in the polar regions1 and spent the winter of that year in the ice4 ,few ships have undergone severer tests than did the ,terror on that voyage4 ,the severest treatment she experienced was in the spring1 when the disruption of the winter ice began to take place4 ,the evening of the #gth of ,march was specially fraught with danger4 ,we quote the gallant commander's graphic account3-- ,ominous rushing sounds were heard far off to the north-east and north-west4 ,these gradually drew nearer as the flood made its way1 either under the compact bodies that withstood the shock1 or along the cracks and openings--gaining in these latter a furious velocity1 to which everything seemed to yield4 ,it happened that there were several of these around the ship2 and when they opened on us like so many conduits pouring their contents to a common centre1 the concussion was absolutely appalling1 rending the lining and bulkheads in every part1 loosening some shores and stanchions1 so that the slightest effort would have thrown them down1 and compressing others with such force as to make the turpentine ooze out of their extremities4 ,one fir plank1 placed horizontally between the beams and the shores actually glittered with globules4 ,at the same time the pressure was going on from the larboard side1 where the three heaviest parts of the ruin of the floe remained1 cracked here and there1 but yet adhering in firm and solid bodies4 ,these1 of course1 were irresistible2 and after much groaning1 splitting1 and cracking1 accompanied by sounds like the explosion of cannon1 the ship rose fore and aft1 and heeled over about ten degrees to starboard4 ,again1 on the #aath1 ,back says3 ,at this time she showed symptoms of suffering in the hull1 which was evidently undergoing a severe ordeal4 ,inexplicable noises1 in which the sharp sounds of splitting and the harsher ones of grinding were most distinct1 came in quick succession1 and then again stopped suddenly1 leaving all so still that not even a breath was heard4 ,in an instant the ship was felt to rise under our feet1 and the roaring and rushing commenced with a deafening din alongside1 abeam and astern1 at one and the same instant4 ,alongside1 the grinding masses held the ship tight as in a vice2 while the overwhelming pressure of the entire body1 advancing from the west1 so wedged the stern and starboard quarter1 that the greatest apprehensions were entertained for the stern-post and framework abaft4 ,some idea of the power exerted on this occasion may be gathered from this3--,at the moment which ,i am now describing1 the fore-part of the ship was literally buried as high as the flukes of the anchors in a dock of perpendicular walls of ice2 so that1 in that part1 she might well have been thought immovable4 ,still1 such was the force applied to her abaft1 that after much cracking and perceptible yielding of the beams1 which seemed to curve upwards1 she actually rose by sheer pressure above the dock forward2 and then1 with sudden jerks1 did the same abaft4 ,during these convulsions1 many of the carpenters and others stationed below were violently thrown down on the deck1 as people are in an earthquake4 ,it was a moment of intense suspense4 ,on the #afth1 another rush drove irresistibly on the larboard quarter and stern1 and forcing the ship ahead1 raised her on the ice4 ,a chaotic ruin followed444 ,the ship was careened fully four streaks1 and sprang a leak as before4 ,scarcely were ten minutes left us for the expression of our astonishment that anything of human build could outlive such assaults1 when another equally violent rush succeeded2 and in its way toward the starboard quarter threw up a rolling wave thirty feet high1 crowned by a blue square mass of many tons1 resembling the entire side of a house1 which1 after hanging for some time in doubtful poise on the ridge1 at length fell with a crash into the hollow1 in which1 as in a cavern1 the after-part of the ship seemed embedded4 ,it was1 indeed1 an awful crisis1 rendered more frightful from the mistiness of the night and dimness of the moon4 ,the poor ship cracked and trembled violently1 and no one could say that the next minute would not be her last--and1 indeed1 his own too1 for with her our means of safety would probably perish4 ,it is unnecessary to give additional instances of this kind1 in order to show the terrible power of field-ice4 ,indeed1 it requires little in the way of illumination to prove that masses of solid matter1 many thousands of tons in weight1 can1 when in motion1 utterly destroy the most powerful engines of human construction4 ,we shall now turn our attention to another1 and a very prominent form1 in which arctic ice presents itself--namely1 that of icebergs4 ,,chapter ,,ten4 ,,icebergs--,,their ,,appearance ,,and ,,forms--,,their ,,cause--,,glaciers--,,their ,,nature ,,and ,,origin--,,anecdote ,,of ,,scoresby--,,risk ,,among ,,icebergs--,,mcclure',s ,,experience4 ,there are not only ice-fields1 ice-floes1 etcetera1 in the polar seas1 but there are ice-mountains1 or bergs4 ,it was long a matter of uncertainty as to where and how those immense mountains1 that are met with occasionally at sea1 were formed4 ,we are now in a position to tell definitely where they originate1 and how they are produced4 ,they are not masses of frozen sea water4 ,their birth-place is in the valleys of the far north1 and they are formed by the accumulation of the snows and ice of ages4 ,this is a somewhat general way of stating the matter2 but our subsequent explanations will1 we trust1 make our meaning abundantly clear4 ,icebergs are found floating in great numbers in the arctic seas4 ,they drift southward each spring with the general body of polar ice1 and frequently travel pretty far south in the ,atlantic before the heat of the water and atmosphere united accomplishes their dissolution4 ,they sometimes travel as far south as ,florida with the southerly current that flows along that coast2 but the warm waters of the ,gulf ,stream1 together with its northerly flow1 form an impassable barrier between these ice-mountains and ,europe4 ,icebergs assume every variety of form1 and almost every size4 ,they sometimes resemble castles1 sometimes churches with glittering spires1 and sometimes the peaked and jagged mountains of ,norway4 ,they are also frequently seen in the form of immense misshapen and top-heavy masses4 ,in size they vary from one hundred to seven or eight hundred feet in height4 ,one iceberg1 seen by ,ross in ,baffin's ,bay1 was above two miles in length1 nearly the same in width1 and fifty feet high4 ,but in stating this1 we have not given the reader any idea of its vast proportions2 for it is well known that all icebergs1 or masses of ice1 have a much greater proportion of their bulk under than above water--in other words1 they sink very deep4 ,the relative proportion that sinks depends on the nature of the ice4 ,of some kinds1 there is usually ten times as much below as there is above water2 of other kinds1 there may be eight or five parts below4 ,in all cases there is much more below than above so that a mountain of a hundred feet high--if afloat--may be safely calculated to be a mass of ice not far short of a thousand feet thick4 ,as these bergs float southward with the currents1 they melt very rapidly4 ,the heat of the sun and the action of the waves gradually round off the sharp angles and topple down the spires that characterised them in the land of their birth4 ,the process of dissolution1 too1 is carried on internally2 for rain and melted water on the surface percolates through the mass1 rendering it porous4 ,as the waves cut away the base1 the centre of gravity is thrown out1 and the whole berg turns over with a terrible crash4 ,sometimes loud reports like cannon-shots are heard1 and the huge mountain splits asunder2 while1 not unfrequently1 the whole berg falls into a heap of chaotic ruins1 and floats away in a mass of smaller pieces which disappear gradually in their parent sea4 ,the formation of icebergs has1 as we have said1 puzzled mankind for many years4 ,their existence has long been known3 for1 even before men dared to venture their lives in the polar regions1 navigators1 in crossing the ,atlantic ,ocean1 frequently met with these marble-like mountains2 and1 what is worse1 sometimes ran at full speed against them1 and were sunk with all on board4 ,bergs are frequently enveloped in dense fogs1 caused by the cold atmosphere by which they are surrounded condensing the moisture of the warmer atmosphere which they encounter on their voyage southward2 hence they are exceedingly dangerous to navigation4 ,but now to speak of their formation4 ,many of the great valleys of the far north are completely filled up with solid ice4 ,observe1 we do not say that they are merely covered over with ice2 they are absolutely filled up with it from top to bottom4 ,those ice-masses are known by the name of glaciers2 and they are found in most of the elevated regions of the ,earth1--on the ,alps and the mountains of ,norway1 for instance1--but they exist in greater abundance about the poles than elsewhere4 ,glaciers never melt4 ,they have existed for unknown ages1 probably since the world began2 and they will1 in all likelihood1 continue to exist until the world comes to an end1--at least until the present economy of the world terminates4 ,they began with the first fall of snow1 and as falls of snow during the long winters of the polar regions are frequent and heavy1 the accumulated masses are many feet deep1 especially in places where drifts are gathered--sometimes fifteen1 twenty1 thirty1 and even forty feet deep4 ,the summer sun could not melt such drifts entirely4 ,new snow was added each winter1 until the valleys of the far north were filled up2 and so they remain filled up to this day4 ,in order to understand the nature of glaciers clearly1 let us turn back to those remote ages that rolled over this ,earth long before man was created4 ,let us in spirit leap back to the time when no living creature existed1 even before the great mastodon began to leave his huge foot-prints on the sands of time4 ,we have reached one of the large valleys of the arctic regions4 ,it is solemn1 grand1 and still4 ,no merry birds1 no prowling creatures1 are there to disturb the universal calm4 ,the ,creator has not yet formed the living creatures and pronounced them very good4 ,it is the world's first winter4 ,as we look upward to the sky1 we observe the first white snow-flakes falling gently to the ground4 ,they reach it1 and1 for the first time1 that valley is covered with a garment of virgin snow4 ,the valley is upwards of two miles broad4 ,it rises from the sea1 and goes far back into the mountains1 perhaps to the extent of ten or twelve miles4 ,the mountains that flank it are five or six thousand feet high4 ,we have seen such valleys in ,norway1 within the arctic circle4 ,before that first winter has passed1 many and many a fall of snow has thickened and pressed down that first coat2 and many a furious storm has caught up the snow from the mountain-tops and swept it into the valley1 adding to and piling up the mass1 and packing it firmly down4 ,spring arrives4 ,the short but warm arctic summer bursts upon that vale1 melting the surface of the snow2 and the water thus produced sinks through the mass1 converting it into a sort of thick slush--half snow1 half water1--not liquid1 yet not solid2 just solid enough to lie there apparently without motion2 yet just liquid enough to creep by slow1 absolutely imperceptible degrees1 down the valley4 ,the snow in all the mountain gorges is similarly affected3 it creeps 7it cannot be said to flow7 out and joins that in the vale4 ,but we cannot perceive any of the motion of which we are writing4 ,the mass of snow seems to be as still and motionless as the rocks on which we stand2 nay1 if we choose we may walk on its hard surface almost without leaving the slightest print of our foot4 ,but if we throw a large stone on the surface of the snow and mark the spot1 and return again after many days1 we shall find that the stone has descended the valley a short distance4 ,we shall also observe that the snow has now a variety of markings on its surface2 which might lead us to fancy1 had we not known better1 that it had once been a river1 which1 while raging down to the sea with all its curling rapids and whirling eddies1 had been arrested in all instant by the ice-king and frozen solid1--in fact1 it has all the graceful lines and forms of fluidity1 with all the steady1 motionless aspect of solidity4 ,it really moves1 this vast body of snow2 but1 like the hour hand of a watch1 its motion cannot be recognised1 though we should observe it with prolonged1 unflagging attention4 ,we have called it a vast body of snow1 but this is only comparatively speaking4 ,it will be vaster yet before we have done with it4 ,at present it is but a thick semi-fluid covering1 lying at the bottom of this ancient arctic vale4 ,the brief summer ends4 ,much of the winter snow has been melted and returned to the sea2 but much1 very much more1 is still lying deep upon the ground4 ,the world's second winter comes4 ,the first frost effectually puts a stop to all the melting and moving that we have been describing4 ,the snow-river no longer moves--it is arrested4 ,the water no longer percolates through the snow--it is frozen4 ,the mass is no longer semi-fluid--it is solid ice2 and the first step in the process of a glacier's formation is begun4 ,thereafter this process is continued from year to year1 each winter adding largely to its bulk1 each summer deducting slightly therefrom4 ,the growing mass of ice ascends the mountain-sides1 swallows the rocks and shrubs and trees in its progress1 until its body becomes a thousand feet thick3 the extreme summits of the mountain-peaks alone tower above the snowy waste1 and the mass at the bottom is now1 by the pressure of superincumbent masses1 pure ice1 hard and clear as crystal4 ,when the great glacier grows old it still maintains its stealthy downward motion during every summer4 ,it has reached the shore1 and has been pushed1 like a huge white tongue1 out into the sea4 ,but what has all this to do with icebergs8 it may be inquired4 ,much1 very much4 ,it is common enough1 in commenting on a child1 to speak of the parent4 ,the glacier is the mother of the iceberg4 ,when1 in the world's early morning1 the embryo glacier reached the sea1 its thin edges were easily broken off by the waves2 but as it increased and still further encroached1 these edges became thicker and thicker1 until at last a wall of pure ice1 several hundred feet high1 presented its glittering front to the ocean4 ,it was hard and massive2 the sun of summer had little effect on its frigid face1 and it seemed to bid defiance to the sea itself4 ,but things often are not what they seem4 ,each billow sapped its foundation2 it soon began to overhang its base4 ,at length the cohesion of the mass was not sufficient to sustain its weight4 ,a rending1 accompanied by sounds like heaven's artillery1 took place2 the crystal mountain bowed its brow and fell with thunderous crash upon the water2 then1 rocking slowly under the impulse of its dread plunge1 the first iceberg floated off to sea6 ,it is right to remark here that this explanation is1 to some extent1 disputed--at least there is a difference of opinion as to the manner in which the iceberg leaves its parent glacier4 ,there is no dispute as to its origin4 ,this difference will be explained shortly in a quotation from ,dr ,kane's work2 meanwhile1 in support of the present theory1 let us listen to the words of one who saw with his own eyes something similar to what has been described4 ,dr ,scoresby1 than whom a better man never explored the arctic seas1 says3-- ,in ,july #ahah1 ,i was particularly fortunate in witnessing one of the grandest effects which these polar glaciers ever present4 ,a strong north-westerly swell1 having for some hours been beating on the shore1 had loosened a number of fragments attached to the iceberg1 and various heaps of broken ice denoted recent shoots of the seaward edge4 ,as we advanced towards it1 with a view of proceeding close to its base1 ,i observed a few little pieces fall from the top2 and while my eye was fixed upon the place1 an immense column1 probably fifty feet square1 and one hundred and fifty feet high1 began to leave the parent ice at the top1 and1 leaning majestically forward1 with an accelerated velocity fell1 with an awful crash1 into the sea4 ,the water into which it plunged was converted into an appearance of vapour or smoke1 like that from a furious cannonading4 ,the noise was equal to that of thunder1 which it nearly resembled4 ,the column which fell was nearly square1 and in magnitude resembled a church4 ,it broke into thousands of pieces4 ,this circumstance was a happy caution1 for we might inadvertently have gone to the very base of the icy cliff from whence masses of considerable magnitude were continually breaking6 ,now1 this incident suggests the probability1 that1 had the face of the glacier projected into deep water1 the mass which broke off might have fallen into the sea without being broken to pieces1 and might have floated away as a berg4 ,we confess1 however1 to be partial to the view expressed by some writers1 that the great glaciers continue year by year to thrust their thick tongues out to sea1 until the projecting masses reach water sufficiently deep to float them1 when they are quietly cracked off from their parent and carried away without any fall or plunge4 ,the following remarks by ,dr ,kane will make this more clear4 ,writing of the iceberg1 he says3 ,so far from falling into the sea1 broken by its weight from the parent glacier1 it rises from the sea4 ,the process is at once gradual and comparatively quiet4 ,the idea of icebergs being discharged1 so universal among systematic writers1 and so recently admitted by myself1 seems to me at variance with the regulated and progressive action of nature4 ,developed by such a process1 the thousands of bergs which throng these seas should keep the air and water in perpetual commotion-- one fearful succession of explosive detonations and propagated waves4 ,but it is only the lesser masses falling into deep waters which could justify the popular opinion4 ,the enormous masses of the ,great ,glacier of ,greenland are propelled step by step1 and year by year1 until1 reaching water capable of supporting them1 they are floated off1 to be lost in the temperatures of other regions444 ,the height of the ice-wall at the nearest point was about three hundred feet1 measured from the water's edge2 and the unbroken right line of its diminishing perspective showed that this might be regarded as its constant measurement4 ,it seemed1 in fact1 a great icy table-land1 abutting with a clean precipice against the sea4 ,this is1 indeed1 characteristic of all those arctic glaciers which issue from central reservoirs1 or mers de glace1 upon the fords or bays1 and is strikingly in contrast with the dependent or hanging glacier of the ravines4 ,elsewhere the same writer speaks of this glacier as a line of cliff1 rising in a solid glassy wall to a height of three hundred feet above the water-level1 and with an unfathomable depth below it2 and its curved face1 sixty miles in length1 from ,cape ,agassiz to ,cape ,forbes1 vanished into unknown space at not more than a single day's rail-road travel from the pole4 ,the interior with which it communicated1 and from which it issued1 was an unsurveyed mer de glace1 or sea of ice1 of apparently boundless dimensions2 and from one part of this great cliff he saw long lines of huge bergs floating slowly away4 ,here1 we think1 is ice enough and of sufficient dimensions to account for the largest bergs that were ever beheld4 ,it will be at once seen1 then1 that icebergs1 though found floating in the sea1 are not necessarily of the sea4 ,they are composed entirely of fresh water1 and arctic ships can at any time procure a plentiful supply of good soft drinkable water from the pools that are formed in the hollows of the bergs4 ,the risk of approaching icebergs in the arctic regions is not so great as when they are found floating further south2 because when in their native regions they are comparatively tough1 whereas on their southern journeys they become more or less disintegrated--in fact1 the blow of an axe is sometimes sufficient to cause a rent1 which in its turn will induce other rents and failings asunder1 so that the whole mass runs the risk of being entirely broken up4 ,hence the danger of ships1 in certain circumstances1 venturing to anchor to them4 ,nevertheless this is a common practice--sometimes a necessity--among discovery ships and whalers4 ,it is a convenient practice too2 for many a vessel has been saved from absolute destruction by getting under the lee of a good sound iceberg1 where she has lain as safely1 for the time being1 as if in a harbour4 ,when ,captain ,mc,clure was endeavouring to make the north-west passage in #ahea1 he was saved1 from what appeared to be at least very probable destruction1 by a small iceberg4 ,on the #agth of ,september he writes3 ,there were several heavy floes in the vicinity4 ,one1 full six miles in length1 passed at the rate of two knots1 crushing everything that impeded its progress1 and grazed our starboard-bow4 ,fortunately there was but young ice upon the opposite side1 which yielded to the pressure2 had it otherwise occurred1 the vessel must inevitably have been cut asunder4 ,in the afternoon we secured to a moderately-sized iceberg1 drawing eight fathoms1 which appeared to offer a fair refuge1 and from which we never afterwards parted4 ,to this lump of ice the ship clung with the tenacity of a bosom friend1 and followed it1 literally1 through thick and thin6 ,there is something almost ludicrous1 as well as striking1 in ,mc,clure's account of their connection with this bit of ice4 ,it conveyed them to their furthest north-east position1 and back round the ,princess ,royal ,islands--passed the largest within five hundred yards--returned along the coast of ,prince ,albert's ,land--and finally froze in at latitude #gj degrees #ej minutes north1 longitude #aag degrees #ee minutes west1 on the #cjth ,september2 during which circumnavigation they received many severe nips1 and were frequently driven close to the shore1 from which their dear friend the iceberg1 small though he was1 kept them off4 ,icebergs assume almost every conceivable form1 and are seen of every size--sometimes1 also1 in great numbers4 ,scoresby mentions one occasion on which he was surrounded by bergs to the number of several hundreds4 ,now1 all this ice that we have been speaking of1 besides being1 in a secondary way1 a passive agent in the affairs of man 7chiefly in barring his progress northward71 is one of the most potent agents in the economy of nature4 ,it is the means by which the world is kept cool enough for man and beast to dwell in4 ,the polar regions--north and south--are1 as it were1 the world's refrigerators2 tempering the heated air of the south1 and1 in connection with the torrid zone1 spreading throughout the ,earth those beneficial influences which gladden the sphere of man's temporal existence4 ,,chapter ,,eleven4 ,,ice ,,an ,,agent

,,dogs--,,intense ,,cold--,,effect ,,on ,,the ,,sea4 ,there are many things in this world which1 up to within a few years back1 have been to men a source of surprise and mystery4 ,some of these problems have been solved by recent travellers1 and not a few of them are referable to polar oceans and ice4 ,in many parts of our coasts we find very striking and enormously large boulder-stones lying on the beach1 perfectly isolated1 and their edges rounded away like pebbles1 as if they had been rolled on some antediluvian beach strewn with ,titanic stones4 ,these boulders are frequently found upon the loose sands of the sea-shore1 far removed from any rocks or mountains from which they might be supposed to have been broken2 and1 more than that1 totally different in their nature from the geological formations of the districts in which they are found4 ,whence came these8 has been the question of the inquisitive of all ages1 and how came they there8 ,there may1 for aught we know to the contrary1 be more than one answer to these questions2 but there is at least one which is quite satisfactory as to how and whence at least some of them have come4 ,ice was the means of conveying these boulders to their present positions4 ,it has been said that once upon a time a large part of this country was under the dominion of ice1 even as the polar regions and some of the mountains and valleys of ,norway are at the present day2 that the boulders we see in elevated places were conveyed thither by glacier action2 and that when the glacial period passed away1 they were left there on the hill-sides--sometimes almost on the mountain-tops4 ,but this is not the question we are considering just now4 ,we are now inquiring into the origin of those huge boulders that are found upon our coasts and on the coasts of other lands--boulders which could not have rolled down from the hills1 for there are no hills at all near many of them2 and those hills that are near some of them are of different geological formation4 ,this question will be answered at once1 and one of the phenomena of arctic ice and oceanic agency will be exhibited1 by reference to the recent discoveries of the celebrated arctic voyager1 ,dr ,kane of the ,american ,navy4 ,while wintering far beyond the head of ,baffin's ,bay1 and beyond the most northerly point1 in that direction1 that had at that time been reached by any previous traveller1 ,dr ,kane made many interesting observations and discoveries4 ,he seems to have penetrated deep into the heart of ,nature's northern secrets4 ,among other things1 he ascertained the manner in which boulders are transported from their northern home4 ,the slow1 creeping movement of glaciers1 to which we have already referred1 is one means whereby large boulders are formed4 ,at the lower edge of one of the glaciers of ,norway we saw boulders1 thirty or forty feet in diameter1 which had been rolled and forced1 probably for ages1 down the valley by the glacier1 and thrust out on the sea-beach1 where they lay with their angles and corners rubbed off and their surfaces rounded and smoothed as completely as those of the pebbles by which they were surrounded4 ,had these boulders been formed in the arctic regions1 they might have been thrust out upon the thick solid crust of the frozen sea1 which in time would have been broken off and floated away2 thus rafting the boulders to other shores4 ,the formation of boulders1 and their positions1 are facts that we have seen4 ,their being carried out to sea by ice-rafts is a fact that ,dr ,kane has seen and recorded4 ,on the wild rocky shores where his ship was set fast1 there was a belt of ice lining the margin of the sea1 which he termed the ice-belt1 or the ice-foot4 ,this belt never melted completely1 and was usually fast to the shore4 ,in fact it was that portion of the sea-ice which was left behind each spring when the general body of ice was broken up and swept away4 ,referring to this1 he writes3 ,the spot at which we landed ,i have called ,cape ,james ,kent4 ,it was a lofty headland1 and the land-ice which hugged its base was covered with rocks from the cliffs above4 ,as ,i looked over this ice-belt1 losing itself in the far distance1 and covered with its millions of tons of rubbish1 greenstones1 limestones1 chlorite1 slates1 rounded and angular1 massive and ground to powder1 its importance as a geological agent1 in the transportation of drift1 struck me with great force4 ,its whole substance was studded with these varied contributions from the shore2 and further to the south1 upon the now frozen waters of ,marshall ,bay1 ,i could recognise raft after raft from the last year's ice-belt which had been caught by the winter1 each one laden with its heavy freight of foreign material4 ,the water torrents and thaws of summer unite with the tides in disengaging the ice-belt from the coast2 but it is not uncommon for large bergs to drive against it and carry away the growths of many years4 ,i have found masses that had been detached in this way1 floating many miles out at sea--long1 symmetrical tables1 two hundred feet long by eighty broad1 covered with large angular rocks and boulders1 and seemingly impregnated throughout with detrited matter4 ,these rafts in ,marshall ,bay were so numerous1 that could they have melted as ,i saw them1 the bottom of the sea would have presented a more curious study for the geologist than the boulder-covered lines of our middle latitudes4 ,one boulder in particular had had its origin in a valley where rounded fragments of water-washed greenstone had been poured out by the torrents and frozen into the coast-ice of the belt4 ,the attrition of subsequent matter had truncated the great egg-shaped rock1 and worn its sides into a striated face1 whose scratches still indicated the line of water-flow4 ,so1 then1 when we next meet with a huge isolated boulder on any of our flat beaches1 we may gaze at it with additional interest1 when we reflect that1 perchance1 it was carried thither by the ocean1 countless ages ago1 from the arctic regions1 on a gigantic raft of ice2 after having been1 at a still more remote period1 torn from its cliffs by some mighty glacier and slowly rolled and rounded1 for hundreds of years perhaps down the scarred slopes of its native valley4 ,the primary cause of the intense and prolonged cold of the arctic regions is the shortness of the time during which they are under the influence of the sun's rays4 ,for a few months in summer the sun shines brightly1 but1 owing to the position of the globe1 obliquely on the poles4 ,during part of that period it shines at mid-night as well as at mid-day4 ,put during the greater part of the year its beams throw but a feeble light there1 and for several months in winter there is absolutely no day at all--nothing but one long dismal night of darkness1 that seems as if the bright orb of day had vanished from the heavens for ever4 ,the length of this prolonged day in summer1 and this dreary night in winter1 depends1 of course1 upon latitude4 ,the length of both increases as we approach the poles4 ,the long daylight in summer is exceedingly delightful4 ,we once saw the sun describe an almost unbroken circle in the sky for many days and nights1 and had we been a few degrees further north we should have seen it describe an entire circle4 ,as it was1 it only disappeared for twenty minutes4 ,it set about midnight1 and in twenty minutes it rose again so that there was no night1 not even twilight1 but a bright1 beautiful blazing day1 for several weeks together4 ,dr ,kane describes the midnight sun thus3 ,on our road we were favoured with a gorgeous spectacle1 which hardly any excitement of peril could have made us overlook4 ,the midnight sun came out over the northern crest of the great berg1 our late fast friend1' kindling variously-coloured fires on every part of its surface1 and making the ice around us one great resplendency of gem-work--blazing carbuncles and rubies1 and molten gold4 ,very different indeed is the aspect of the winter night4 ,let the same authority speak1 for he had great experience thereof4 ,on ,december #aeth he writes3 ,we have lost the last vestige of our mid-day twilight4 ,we cannot see print1 and hardly paper4 ,the fingers cannot be counted a foot front the eyes4 ,noonday and midnight are alike2 and1 except a vague glimmer on the sky1 that seems to define the hill-outlines to the south1 we have nothing to tell us that this arctic world of ours has a sun4 ,in one week more we shall reach the midnight of the year444 ,the influence of this long intense darkness was most depressing4 ,even our dogs1 although the greater number of them were natives of the arctic circle1 were unable to withstand it4 ,most of them died from an anomalous form of disease1 to which ,i am satisfied1 the absence of light contributed as much as extreme cold4 ,quoting from his journal he says3 ,i am so afflicted with the insomnia of this eternal night1 that ,i rise at any time between midnight and noon4 ,i went on deck this morning at five o'clock4 ,it was absolutely dark2 the cold not permitting a swinging lamp1 there was not a glimmer came to me through the ice-crusted window-panes of the cabin4 ,while ,i was feeling my way1 half puzzled as to the best method of steering clear of whatever might be before me1 two of my ,newfoundland dogs put their cold noses against my hand1 and instantly commenced the most exuberant antics of satisfaction4 ,it then occurred to me how very dreary and forlorn must these poor animals be1 at atmospheres #aj degrees above zero in-doors and #ej degrees below zero without--living in darkness1 howling at an accidental light1 as if it reminded them of the moon--and with nothing1 either of instinct or sensation1 to tell them of the passing hours1 or to explain the long lost daylight4 ,they shall see the lantern more frequently4 ,yet this state of midnight darkness is not altogether unmitigated4 ,there are a few ameliorating influences at work1 the nature of some of which we will treat of in the next chapter4 ,among others1 the moon frequently shines there with great brilliancy in winter4 ,dr ,kane says that in ,october the moon had reached her greatest northern declination3 ,she is a glorious object4 ,sweeping around the heavens1 at the lowest part of her curve she is still #ad degrees above the horizon4 ,for eight days she has been making her circuit with nearly unvarying brightness4 ,it is one of those sparkling nights that bring back the memory of sleigh-bells and songs and glad communings of hearts in lands that are far away4 ,but despite all the varied and transient beauties of the northern skies in winter1 the long arctic night is undoubtedly depressing in the extreme4 ,in these regions men speak of being able to read the thermometer on the #gth of ,november at noonday without a light1 as being matter for gratulation4 ,the darkness still before them at that time would be of about three months' duration1 and even then they would only get back to a species of twilight4 ,the cold experienced by these navigators of the northern seas is terribly intense4 ,their thermometers have frequently indicated a temperature as low as #ge degrees below zero1 or #ajg degrees of frost1 on ,fahrenheit's scale4 ,the thermometers of arctic explorers are always filled with spirits of wine1 as quicksilver freezes at about #dj degrees below zero1 and is therefore unsuitable4 ,it would be frozen1 indeed1 the greater part of the winter4 ,dr ,kane says3 ,at such temperatures chloric ether became solid1 and carefully prepared chloroform exhibited a granular pellicle on its surface4 ,spirits of naphtha froze at #ed degrees below zero1 and oil of sassafras at #di degrees4 ,the oil of winter-green was in a flocculent state at #ef degrees1 and solid at #fc degrees4 ,the exhalations from the surface of the body invested the exposed or partially clad parts with a wreath of vapour4 ,the air had a perceptible pungency upon inspiration1 but ,i could not perceive the painful sensation which has been spoken of by some ,siberian travellers4 ,when breathed for any length of time1 it imparted a sensation of dryness to the air-passages4 ,i noticed that1 as it were involuntarily1 we all breathed guardedly1 with compressed lips4 ,now1 strange to say1 this extremely low temperature does not affect the ocean to any great depth4 ,just below the ice1 in cold such as the above1 the sea was found to be #bi degrees above zero4 ,no doubt1 deeper down1 the temperature was still warmer4 ,we have heard it said1 that when men chance to fall into the water in cold regions1 in the depth of winter1 it feels at first rather warm and agreeable6 ,on scrambling out again1 however1 their condition is not enviable2 for in a few minutes the keen frost causes their garments to become as hard as boards4 ,much light has been thrown on the fact of the existence of under and upper currents in the sea1 by the phenomena of the arctic regions1 and some of the questions to which these currents give rise are so interesting that we shall treat of them in a new chapter4 ,,chapter ,,twelve4 ,,question ,,of ,,an ,,open ,,sea ,,round ,,the ,,poles--,,upper ,,and ,,under ,,currents ,,of ,,the ,,ocean--,,cause ,,thereof--,,habits ,,of ,,the ,,whale ,,as ,,bearing ,,on ,,the ,,question-- ,,dr4 ,,kane',s ,,discovery ,,of ,,an ,,open ,,sea ,,in ,,the ,,far ,,north--,,notes ,,on ,,the ,,expedition--,a ,,bear-,,hunt4 ,it was long and very naturally supposed that the impenetrable ice of the arctic regions extended to1 and1 as it were1 sealed up the pole4 ,but from time to time philosophic observers of ,nature's laws began to hint their opinion that there is an open ocean around the pole2 and of late years this opinion has all but been converted into a firm belief4 ,maury remarks1 that like air--like the body--the ocean must have a system of circulation for its waters4 ,and an attentive study of the currents of the sea1 and a close examination of the laws which govern the movements of the waters in their channels of circulation through the ocean1 will lead us irresistibly to the conclusion that always1 in summer and winter1 there must be1 somewhere within the arctic circle1 a large body of open water4 ,there is an under-current setting from the ,atlantic1 northward through ,davis' ,straits1 into the ,arctic ,ocean1 and a surface-current setting out4 ,the fact is proved beyond a doubt by the observations of arctic explorers1 who have seen immense icebergs drifting rapidly northward against a strong current4 ,this apparent anomaly could only be accounted for by the fact that a powerful undercurrent carried them northward2 and as at least seven times more of these bergs must have been under than above water1 we can easily understand how the under-current1 acting on the larger mass of each berg1 had power to carry it against the surface-current4 ,this under-current is warm1 while the upper-current is cold4 ,now we know that according to ,nature's laws1 heated water1 like heated air1 rises to the surface1 and cold water sinks to the bottom4 ,how1 then1 comes this warm current to be underneath the cold1 as soundings have proved it to be8 ,it is owing to the fact that the under-current is much salter1 and therefore heavier 7despite its warmth71 than the surface-current2 which latter1 being mingled with the drainage and ice-masses of the arctic regions1 is comparatively fresh1 and therefore light as well as cold4 ,the hot and salt waters of the tropics are carried north by the ,gulf ,stream4 ,there are here two counteracting agents at work4 ,heat inclines the ,gulf ,stream to rise2 saltness inclines it to sink4 ,during the first part of its journey1 as we know1 its great heat prevails over the other influence1 and it flows as a surface-current4 ,but1 at a certain point in its northward route1 it meets with the cold1 brackish1 ice-bearing currents that flow out of the arctic basin4 ,having lost much of its heat 7though still possessing a great deal more than the arctic currents71 the saltness of the ,gulf ,stream prevails2 it dips below the polar waters1 and thenceforth continues its course as an under-current1 salt1 and comparatively warm4 ,to state the matter briefly3 ,the hot water1 which ought to keep on the surface because of its heat1 is sunk by its superabundant salt2 and the cold water1 which ought to sink because of its cold1 is buoyed on the surface because of its want of salt4 ,now arises the question--what becomes of the great quantity of salt that is thus being carried perpetually into the polar basin8 ,manifestly it must be carried out again by the surface-current1 otherwise the polar basin would of necessity become a basin of salt4 ,the under-current must1 therefore1 rise to the surface somewhere near the pole1 with its temperature necessarily only a little1 if at all1 below the freezing-point--which1 be it observed1 is a warm temperature for such regions4 ,here1 then1 where the warm waters from the south rise to the surface1 it is supposed this open ,arctic ,ocean must exist4 ,so much for theory4 ,now for facts that have been observed1 and that tend1 more or less1 to corroborate this proposition of an open polar sea4 ,the habits of the whale have gone far to prove it4 ,the log-books of whalers have for many years been carefully examined and compared by scientific men4 ,these investigations have led to the discovery that the tropical regions of the ocean are to the right' whale as a sea of fire1 through which he cannot pass1 and into which he never enters4 ,it has also been ascertained that the same kind of whale which is found off the shores of ,greenland1 in ,baffin's ,bay1 etcetera1 is found in the ,north ,pacific1 and about ,behring's ,straits2 and that the right' whale of the southern hemisphere is a different animal from that of the northern4 ,how1 then1 came the ,greenland whales to pass from the ,greenland seas to the ,pacific8 ,not by the ,capes ,horn or ,good ,hope2 the sea of fire precluded that4 ,clearly there was ground here for concluding that they did so through the 7supposed7 open sea lying beyond1 or rather within1 the frozen ocean4 ,it is true the objection might be made1 that the same kind of whale which exists in the ,north ,pacific exists also in the ,north ,atlantic1 although they never cross over to see each other4 ,but another discovery has met this objection4 ,it is the custom among whalers to have their harpoons marked with date and name of ship1 and ,dr ,scoresby1 in his work on arctic voyages mentions several instances of whales having been taken near ,behring's ,straits1 with harpoons in them bearing the stamp of ships that were known to cruise in the ,greenland seas2 and the dates on the harpoons were so recent as to preclude the supposition that the said whales had1 after being struck1 made a voyage round the capes above mentioned1--even were such a voyage possible to them4 ,all this does not1 indeed1 absolutely prove the existence of an open arctic sea1 but it does1 we think1 prove the existence of at least an occasionally open sea there1 for it is well known that whales cannot travel such immense distances under ice4 ,but the most conclusive evidence that we have in regard to this subject is the fact1 that one of the members of ,dr ,kane's expedition1 while in search of ,sir ,john ,franklin1 did actually1 on foot1 reach what we have every reason to believe was this open sea2 but not being able to get their ship into it1 the party had no means of exploring it1 or extending their investigations4 ,the account of this discovery is so interesting1 and withal so romantic1 that we extract a few paragraphs relating to it from ,kane's work4 ,after spending the dreary winter in the ice-locked and unexplored channels beyond the head of ,baffin's ,bay1 ,kane found his little ship still hopelessly beset in the month of ,june2 he therefore resolved to send out a sledge-party under ,morton1 one of his best men1 to explore the channel to the north of their position4 ,after twelve days' travelling they came to the base of the ,great ,glacier1 where ,morton left his party1 and1 in company with an ,esquimaux named ,hans1 set out with a dog-sledge to prosecute the journey of exploration4 ,they walked on the sea-ice in a line parallel with the glacier1 and proceeded twenty-eight miles that day1 although the snow was knee-deep and soft4 ,at the place where they encamped a crack enabled them to measure the ice4 ,it was seven feet five inches thick6 ,and this in ,june4 ,we may mention here1 in passing1 that ,dr ,kane never got his vessel out of that frozen strait1 which seems to be bound by perpetual ice4 ,he and his party escaped with their lives2 but the vessel that bore them thither is probably still embedded in that ice4 ,next day ,morton and ,hans came to a region of icebergs1 which had arrested a previous sledging-party of the same expedition4 ,these icebergs were generally very high1 evidently newly separated from the glacier4 ,their surfaces were fresh and glassy1 and not like those generally met with in ,baffin's ,bay1--less worn1 and bluer1 and looking in all respects like the face of the ,great ,glacier4 ,many were rectangular1 some of them regular squares1 a quarter of a mile each way2 others more than a mile long4 ,to pass amidst these bergs was a matter of labour1 difficulty1 and danger4 ,sometimes the sides of them came so close together1 that the men could scarcely squeeze between them1 and they were obliged to search for other passages2 in doing which1 the variation of their compass confused them4 ,at other times1 a tolerably wide passage would appear between two bergs1 which they would gladly follow2 then a narrower one2 then no opening in front1 but one to the side4 ,following that a little distance1 a blank ice-cliff would close the way altogether1 and they were forced to retrace their steps and begin again4 ,thus they puzzled their way through1 like a blind man in the streets of a strange city2 but more difficulties awaited them beyond4 ,after advancing many miles they were arrested by broad rents in the ice1 and were obliged to diverge frequently far out of their course1 or to bridge the chasms over by cutting down the ice hummocks and filling them up with loose ice1 until the dogs were able to haul the provision-sledge over4 ,advancing thus for several days1 and encamping on the snow at night1 they at last came to a spot where the ice was dangerous4 ,it was weak and rotten1 and the dogs began to tremble4 ,proceeding at a brisk rate1 they had got upon unsafe ice before they were aware of it4 ,their course was at the time nearly up the middle of the channel2 but as soon as possible they turned1 and by a backward circuit reached the shore4 ,the dogs1 as their fashion is1 at first lay down and refused to proceed1 trembling violently4 ,the only way to induce the terrified1 obstinate brutes to get on1 was for ,hans to go to a white-looking spot1 where the ice was thicker1 the soft stuff looking dark2 then calling the dogs coaxingly by name1 they would crawl to him on their bellies4 ,so they retreated from place to place1 until they reached the firm ice they had quitted4 ,a half mile brought them to comparatively safe ice1 a mile more to good ice again4 ,in the midst of this danger they had1 during the liftings of the fog1 sighted open water4 ,soon after they saw it plainly4 ,so many long and dreary months had these men passed since they were gladdened by the sight of open water1 that they could scarcely believe their eyes2 and ,morton declared1 that but for the birds which were seen flying about it in great numbers1 he would not have believed it4 ,they made for the land-ice as fast as possible1 and quickly gained it2 but the sea-ice had cracked off and sunk so much1 that the land-ice presented a wall along the whole coast of about eight or nine feet high4 ,it was quite perpendicular1 in some places overhanging1 so that it was a matter of the greatest difficulty they managed to throw up the provisions1 clamber up themselves1 and haul the dogs and sledge up afterwards4 ,this accomplished1 however1 they were safe1 and could advance with confidence4 ,but this mass of land-ice became narrower as they proceeded1 till at last it dwindled to a mere narrow ledge1 clinging to the high1 perpendicular cliffs1 and looking as if at any moment it might crumble off and fall with them into the open water between it and the floating sea-ice4 ,the sea here was very deep and clear4 ,they could see the bottom quite plainly1 although a stone they cast in1 the size of a man's head1 took twenty-eight seconds to reach it4 ,being now afraid of the ice-ledge1 they attempted to find a path along the face of the cliff2 but failing in this1 ,morton determined to leave part of the provisions in cache1 and proceed with a lighter load4 ,the cape round which they were travelling1 and on the other side of which lay the open water1 was extremely bold1 and the ice-ledge at the end of it was barely three feet wide2 so they were obliged to unloose the dogs1 and drive them forward alone1 then tilted the sledge on one runner1 and thus pushed it past the worst place4 ,here the ice on the sea was partly broken up1 and a strong tide was running from the southward4 ,the night before it had been running from the north4 ,as they advanced1 the channel became still more open1 and after passing the cape they saw nothing but open water1 with innumerable wild sea-birds of every description flying overhead1 or disporting in the pools4 ,let it by observed here1 however1 that this was the open water of a strait or channel1--not the great ,arctic ,sea1 about the probable existence of which we have been writing4 ,upon the ice-masses near them numerous seals were seen basking4 ,one thing that struck them much here was1 that although strong north winds1 amounting to a gale at times1 had been blowing for several days1 no ice had been brought down from the north into the channel1 along the shore of which they travelled4 ,thick1 damp fogs prevailed1 preventing them from seeing far in advance at any time4 ,at last they came to a place where the broken ice of the shore rendered passage for the sledge impossible4 ,they therefore tied the dogs1 intending to push forward a short way alone4 ,but they had not been sufficiently careful to secure them2 for the poor animals1 supposing themselves deserted1 no doubt1 succeeded in breaking their lines1 and rejoined the two men in about an hour after4 ,this1 as it turned out1 was rather a fortunate circumstance4 ,preparatory to quitting their sledge1 the men had loaded themselves with eight pounds of pemmican and two of biscuit1 besides the artificial horizon1 sextant1 and compass1 a rifle1 and a boathook4 ,they had not been an hour gone when1 as above stated1 four of the dogs overtook them4 ,an hour afterwards they came upon a polar bear with her cub4 ,the fight that followed1 although somewhat foreign to our subject1 is so graphically described by ,dr ,kane1 that we think it quite unnecessary to apologise for inserting it here4 ,the bear instantly took to flight2 but the little one being unable to keep pace with her1 she turned back1 and1 putting her head under its haunches1 threw it some distance4 ,the cub safe for the moment1 she would then wheel round and face the dogs1 so as to give it a chance to run away2 but it always stopped1 just as it alighted1 till she came up and threw it ahead again2 it seemed to expect her aid1 and would not go on without it4 ,sometimes the mother would run a few yards ahead1 as if to coax the young one up to her1 and when the dogs came up she would turn and drive them back then1 as they dodged her blows1 she would rejoin the cub and push on1 sometimes putting her head under it1 sometimes catching it in her mouth by the nape of the neck4 ,for a time she managed her retreat with great celerity1 leaving the two men far in the rear4 ,they had engaged her on the land-ice2 but she led the dogs in-shore1 up a small stony valley which opened into the interior4 ,after she had gone a mile and a half1 her pace slackened1 and1 the little one being jaded1 she soon came to a halt4 ,the men were then only half a mile behind1 and running at full speed4 ,they soon came up to where the dogs were holding her at bay4 ,the fight was now a desperate one4 ,the mother never went more than two yards ahead1 constantly looking at the cub4 ,when the dogs came near her1 she would sit upon her haunches1 and take the little one between her hind-legs1 fighting the dogs with her paws1 and roaring so that she could have been heard a mile off4 ,never was an animal more distressed4 ,she would stretch her neck and snap at the nearest dog with her shining teeth1 whirling her paws like the arms of a windmill4 ,if she missed her aim1 not daring to pursue one dog lest the others should harm the cub1 she would give a great roar of baffled rage1 and go on pawing and snapping1 and facing the ring1 grinning at them with her mouth stretched wide4 ,when the men came up the little one was perhaps rested1 for it was able to turn round with its dam1 no matter how quick she moved1 so as to keep always in front of her belly4 ,the five dogs were all the time frisking about her actively1 tormenting her like so many gad-flies4 ,indeed they made it difficult to take an aim at her without killing them4 ,but ,hans1 lying on his elbow1 took a quiet aim1 and shot her through the head4 ,she dropped and rolled over dead1 without moving a muscle4 ,the dogs sprang towards her at once2 but the cub jumped upon her body and reared up1 for the first time growling hoarsely4 ,they seemed quite afraid of the little creature1 she fought so actively1 and made so much noise2 and1 while tearing mouthfuls of hair from the dead mother1 they would spring aside the minute the cub turned towards them4 ,the men drove the dogs off for a time1 but were obliged to shoot the cub at last1 as she would not quit the body4 ,hans fired into her head4 ,it did not reach the brain1 though it knocked her down2 but she was still able to climb on her mother's body1 and try to defend it1 her mouth bleeding like a gutter-spout4 ,they were obliged to despatch her with stones4 ,after skinning the old one they gashed its body1 and the dogs fed upon it ravenously4 ,the little one they cached for themselves against their return4 ,this little fight quite knocked up ,hans the ,esquimaux2 ,morton therefore advanced alone1 in the hope of being able to get beyond a huge cape that lay before him4 ,on reaching it1 the grand sight of an apparently boundless ocean of open water met his eye4 ,only four or five small pieces of ice were seen on the glancing waves of this hitherto unknown sea4 ,viewed from the cliffs1 writes ,dr ,kane1 and taking thirty-six miles as the mean radius open to reliable survey1 this sea had a justly-estimated extent of more than #djjj square miles4 ,here1 then1 in all probability1 is the great ,arctic ,ocean that has been supposed to exist in a perpetually fluid state round the pole1 encircled by a ring of ice that has hitherto presented an impenetrable barrier to all the adventurers of ancient and modern times4 ,there were several facts connected with this discovery that go far to prove that this ocean is perpetually open4 ,further south1 where ,dr ,kane's brig lay in ice that seemed never to melt1 there were few signs of animal life--only a seal or two now and then2 but here1 on the margin of this far northern sea1 were myriads of water-fowl of various kinds4 ,the ,brent goose1 writes the ,doctor1 had not been seen before since entering ,smith's ,strait4 ,it is well known to the polar traveller as a migratory bird of the ,american continent4 ,like the others of the same family1 it feeds upon vegetable matter1 generally on marine plants1 with their adherent molluscan life4 ,it is rarely or never seen in the interior2 and from its habits may be regarded as singularly indicative of open water4 ,the flocks of this bird1 easily distinguished by their wedge-shaped line of flight1 now crossed the water obliquely1 and disappeared over the land to the north-east4 ,the rocks on shore were crowded with sea-swallows1 birds whose habits require open water2 and they were already breeding4 ,the gulls were represented by no less than four species4 ,the kittiwakes--reminding ,morton of old times in ,baffin's ,bay'--were again stealing fish from the water 7probably the small whiting71 and their grim cousins1 the burgomasters1 enjoying the dinner thus provided at so little cost to themselves4 ,it was a picture of life all round4 ,here1 for the first time1 ,morton noticed the arctic petrel1--a fact which shows the accuracy of his observation1 though he had not been aware of its importance4 ,this bird had not been met with since we left the north water of the ,english whalers1 more than two hundred miles south of the position on which he stood4 ,its food is essentially marine2 and it is seldom seen in numbers1 except in the highways of open water frequented by the whale and the larger representatives of ocean life4 ,they were in numbers flitting and hovering over the crests of the waves1 like their relatives of kinder climates1--the ,cape of ,good ,hope pigeons1 ,mother ,carey's chickens1 and the petrels everywhere else4 ,it must have been an imposing sight1 as ,morton stood at this termination of his journey1 looking out upon the great waste of waters before him4 ,not a speck of ice could be seen4 ,there1 from a height of #dhj feet1 which commanded a horizon of almost forty miles1 his ears were gladdened with the novel music of dashing waves2 and a surf1 breaking in among the rocks at his feet1 stayed his further progress4 ,strong presumptive evidence1 all this1 that there is an ocean of open water round the pole1 and a milder climate there than exists nearer to the arctic circle4 ,had the short barrier of ice that intervened between the brig and that mysterious sea been removed1 as1 perchance1 it is sometimes removed by a hot summer1 ,dr ,kane might have been the first to reach the ,north ,pole4 ,this1 however1 is reserved for some other navigator4 ,the gallant ,kane now lies in an early grave but some of his enterprising comrades have returned to those regions1 bent on solving this problem2 and it is possible that1 even while we now write1 their adventurous keel may be ploughing the waters of the hitherto untraversed and mysterious polar sea4 ,,chapter ,,thirteen4 ,,miscellaneous ,,phenomena ,,of ,,the ,,polar ,,seas ,,and ,,regions--,,the ,,aurora ,,borealis--,,ice-,,blink--,,optical ,,illusions--,,anecdote ,,of ,,scoresby--,,haloes-- ,,coronae--,,mock ,,suns--,,refraction--,,frosts4 ,owing to the intensity of the cold in the arctic regions1 there are1 as we may readily believe1 many singular appearances connected with the ocean and the atmosphere1 which are worthy of special notice4 ,chief1 perhaps1 among the phenomena of those regions is the ,aurora ,borealis4 ,ever mindful of the welfare of the creatures whom he has formed1 the ,almighty has appointed a light to mitigate the darkness of the polar regions when the sun1 in its appointed course1 withdraws for a season4 ,what the aurora borealis is no one knows1 although many have hazarded opinions regarding it4 ,what it is like is known even to ourselves1 though the faint indications of it which sometimes seen in our own heavens are not to be compared to the brilliancy of the spectacle that is occasionally presented in the northern skies4 ,the most ordinary aspect of the aurora is that of a band of pale-green light extending irregularly over part of the sky1 and marked by wavy motions1 as well as by varying brightness4 ,sometimes one part of this band becomes more bright than another part4 ,sometimes the whole seems to move gently1 like the undulations of a flag in a light breeze2 at other times more vigorous action takes place1 and pointed tongues of light shoot vividly up into the zenith4 ,this sometimes takes place so frequently1 and the tongues are so long and numerous1 that the aurora has been popularly termed the northern streamers4 ,although pale-green is the most frequent colour1 the aurora borealis has often been observed with blue and red hues2 and the sky has been seen suffused with an intense crimson colour by it4 ,captains ,parry and ,lyon saw these northern lights in full splendour during their residence in the arctic regions4 ,they tell us that the aurora had a tendency to form an irregular arch1 which1 in calm weather1 was very often distinct1 though its upper boundary was seldom well defined2 but whenever the air was agitated1 showers of rays spread in every direction with the rapidity of lightning1 but always appearing to move to and from a fixed point1 somewhat like a ribbon held in the hand and shaken with an undulatory motion4 ,no rule1 however1 could be traced in the movement of those lighter parcels called the merry dancers1' which flew about perpetually towards every quarter2 becoming in stormy weather more rapid in their motions1 and sharing all the wildness of the blast4 ,they gave an indescribable air of magic to the whole scene1 and made it not wonderful that1 by the untaught ,indian1 they should be viewed as the spirits of his fathers roaming through the land of souls4' ,we are told by some that the aurora borealis is accompanied by a loud hissing and crackling sound and ,captain ,lyon says that the sudden glare and rapid bursts of those wondrous showers of fire make it difficult to believe that their movements are wholly without sound4 ,yet such would seem to be the case1 for the same authority tells us that he stood on the ice for hours listening intently and could hear nothing4 ,he was thoroughly convinced that no sound proceeds from the aurora1 and most intelligent voyagers support him in this opinion4 ,that the aurora dims the lustre of the stars seen through it1 is a fact which was ascertained clearly by the same gentleman2 and that it moves in a region beyond the clouds is also evident from the fact that when the latter covered the sky the aurora disappeared4 ,but some of the most singular appearances of the sea and sky in the polar regions are presented in summer4 ,during that season the perpetual presence of the sun and the large tracts of ice floating about on the sea exert their opposing influences so as to produce the most astonishing results4 ,one part of the sea being covered with ice1 produces a cold atmosphere2 another part being free from ice1 produces a warmer atmosphere4 ,refraction is the result of viewing objects through those different media1 and very curious appearances follow4 ,when ,scoresby was in ,greenland a singular atmospheric phenomenon occurred1 whereby he became aware of the approach of his father's ship some time before it rose above the horizon4 ,he had reached ,greenland before his father1 who followed him in the ,fame4 ,the following is his account of the circumstance3 ,on my return to the ship1 about eleven o'clock1 the night was beautifully fine and the air quite mild4 ,the atmosphere1 in consequence of the warmth1 being in a highly refractive state1 a great many curious appearances were presented by the land and icebergs4 ,the most extraordinary effect of this state of the atmosphere1 however1 was the distinct inverted image of a ship in the clear sky1 over the middle of the large bay or inlet1 the ship itself being entirely beyond the horizon4 ,appearances of this kind ,i have before noticed1 but the peculiarities of this were the perfection of the image1 and the great distance of the vessel that it represented4 ,it was so extremely well defined1 that1 when examined with a telescope1 ,i could distinguish every sail1 the general rig of the ship1' and its peculiar character2 insomuch that ,i confidently pronounced it to be my father's ship the ,fame1 which it afterwards proved to be1 though1 on comparing notes with my father1 ,i found that our relative positions at the time gave our distance from one another very nearly thirty miles1 being about seventeen miles beyond the horizon1 and some leagues beyond the line of direct vision4 ,scoresby was1 perhaps1 one of the most persevering and intelligent observers of nature that ever went to the polar seas4 ,his various accounts of what he saw are most interesting4 ,we cannot do better than quote his remarks upon ice-blink1 that curious appearance of white light on the horizon1 whereby voyagers are led to infer the presence of ice3-- ,this appearance of the ice-blink1 says he1 occurred on the #acth of ,june #ahbj1 in latitude #gf degrees north4 ,the sky aloft was covered with dense1 uniform1 hazy cloud1 which indeed occupied the whole of the heavens1 excepting a portion near the horizon1 where it seemed to be repelled4 ,the upper white blink referred to ice about six miles distant1 being beyond the horizon2 the narrow yellowish portions referred to floes and compact ice2 the lowest yellow blink1 which in brightness and colour resembled the moon1 was the reflection of a field at the distance of thirty miles1 to which1 directed by the blink1 we made way in the ,baffin1 through the channels of water represented in the sky by bluish-grey streaks4 ,the field we found to be a sheet of ice #aej miles in circumference6 ,another very singular appearance observed occasionally in foggy weather is a series of bright circles1 or coronae1 surrounding the heads or persons of individuals in certain positions4 ,we have1 while standing at the mast-head of a vessel in ,hudson's ,straits1 observed our own shadow thrown on the sea with a bright halo round it4 ,the day was bright and hazy at the time4 ,referring to a particular case of this kind1 ,scoresby says3 ,during the month of ,july #ahbj1 the weather being often foggy1 with a bright sun sometimes shining at the height of the day1 some extraordinary coronae were observed from the mast-head4 ,these occurred opposite to the sun1 the centre of all the circles being in a line drawn from the sun through the eye of the observer4 ,on one occasion four coloured luminous circles were observed4 ,the exterior one might be twenty degrees in diameter4 ,it exhibited all the colours of the spectrum4 ,the next1 a little within it1 was of a whitish-grey colour2 the third was only four or five degrees in diameter1 and though it exhibited the colours of the spectrum1 these colours were not very brilliant4 ,the fourth was extremely beautiful and brilliant4 ,the interior colour was yellow1 then orange1 red1 violet1 etcetera4 ,the colours of the whole three coronae were1 ,i think1 in the same order1 but of this ,i am not very certain4 ,indeed1 on reflection1 ,i suspect that the second circle must have been in the reverse order of the first2 the first and the fourth being the same4 ,the third was not coloured4 ,in the midst of these beautiful coronae ,i observed my own shadow1 the head surrounded by a glory4 ,all the coronae were evidently produced by the fog2 my shadow was impressed on the surface of the sea4 ,the cause of these phenomena is the reflection of the sun's rays1 decomposed by different refractions in minute globules of water1 of which the mist1 wherein the coronae occur1 in a great measure appears to consist4 ,mock suns1 or parhelia1 are common appearances in northern skies4 ,sometimes two of these mock suns are seen1 one on each side of their great original1 glowing so brightly that either of them1 if we could suppose it to have shone in the sky alone1 would have made a very respectable sun indeed6 ,even four of these sun-dogs--as they are some times called--have been seen surrounding the sun2 one on each side of it1 one directly above1 and one immediately below1 with a ring of light connecting them together1 a streak of light passing horizontally and another passing perpendicularly between them1 thus forming a luminous cross1 in the centre of which was the sun itself4 ,this magnificent spectacle is sometimes enhanced by a second circle of light enclosing the whole1 and the edges of several outer circles springing in faint light therefrom until gradually lost1 leaving the imagination to call up the idea of an endless series of glories extending over the whole sky4 ,refraction frequently causes grotesque as well as wonderful and beautiful appearances4 ,ships are sometimes seen with their hulls flattened and their masts and sails drawn out to monstrous dimensions2 or the hulls are heightened so as to appear like heavy castle walls1 while the masts and sails are rendered ludicrously squat and disproportioned2 and not only so1 but ships are often seen with their images inverted over their own masts1 so that to the observer it appears as if one ship were balancing another upside down--mast-head to mast-head4 ,land and icebergs assume the same curious appearances--peaks touching peaks1 one set pointing upwards1 the other set pointing down1 while the broad bases are elevated in the air4 ,at other times the whole mass of land and ice on the horizon is more or less broken up and scattered about as if in confusion1 yet with a certain amount of regularity in the midst of it all1 arising from the fact of every object being presented in duplicate1 sometimes triplicate1 and occasionally1 though seldom1 four-fold4 ,when sharp sudden frosts occur in those regions1 the splendour of the scenery is still further enhanced by the formation of innumerable minute crystals which sparkle literally with as much lustrous beauty as the diamond4 ,on one occasion ,scoresby's ship was decorated with uncommon magnificence1 and in a peculiarly interesting manner4 ,in the course of the night1 he writes1 the rigging of the ship was most splendidly decorated with a fringe of delicate crystals4 ,the general form of these was that of a feather having half of the vane removed4 ,near the surface of the ropes was first a small direct line of very white particles1 constituting the stem or shaft of the feather2 and from each of these fibres1 in another plane1 proceeded a short delicate range of spiculae or rays1 discoverable only by the help of a microscope1 with which the elegant texture and systematic construction of the feather were completed4 ,many of these crystals1 possessing a perfect arrangement of the different parts corresponding with the shaft1 vane1 and rachis of a feather1 were upwards of an inch in length1 and three-fourths of an inch in breadth4 ,some consisted of a single flake or feather1 but many of them gave rise to other feathers1 which sprang from the surface of the vane at the usual angle4 ,there seemed to be no limit to the magnitude of these feathers1 so long as the producing cause continued to operate1 until their weight because so great1 or the action of the wind so forcible1 that they were broken off and fell in flakes to the deck of the ship4 ,it is impossible for the mind to conceive the effect of such a galaxy of curious1 and bright1 and eminently beautiful combinations as are sometimes displayed in the arctic regions4 ,none of the fabulous conceptions of man1 even though profoundly elaborated and brightly gilded with the coruscations of the most sparkling genius and fancy1 ever produced so gorgeous a spectacle as may be witnessed there every summer day4 ,four or five suns in the blue sky1 with lines and circles of light shooting from or circling round them6 ,ice in all its quaint1 majestic1 and shining forms1 rendered still more quaint and grand by the influence of refraction2 and1 by the same power1 ships sailing in the sky1 sometimes1 as if ,nature's laws were abrogated1 with their keels upwards1 and their masts pointing to the sea6 ,walls of pure ice hundreds of feet high1 many miles in extent1 clear as crystal1 and sending back the rays of heaven's luminaries in broad blazing beams2 while the icebergs' pinnacles reflect them in sparkling points6 ,white luminous fogs1 like curtains of gauze1 too thin to dim the general brightness1 yet dense enough to invest the whole scene with a silver robe of mystery1 and to refract the light and compel it to shine in great circles of prismatic colours6 ,and everything--from the nature of the materials of which the gay scenery is composed--either white or blue1 varying in all gradations from the fairest snow to the deepest azure1 save where the rainbow's delicate hues are allowed to intermingle enough of pink1 yellow1 purple1 orange1 and green to relieve the eye and enable it more fully to appreciate the virgin drapery of the scene4 ,all this1 seen in detail--seen frequently in rapid succession--sometimes seen almost all at one moment1--all this is absolutely beyond conception1 and utterly beyond adequate description4 ,yet all this is seen at times in those realms of ice and snow1 which are1 as we have already said1 too much represented as the gloomy1 forbidding1 inhospitable polar regions4 ,there are two sides to every picture4 ,we take leave of this particular branch of our sun with the remark1 that if the shady side of the far north is dreadfully dark and dreary1 its bright side is intensely brilliant and beautiful4 ,,chapter ,,fourteen4 ,,animal ,,life ,,in ,,the ,,sea--,,medusae--,,food ,,of ,,the ,,whale--,,phosphoric ,,light-- ,,cause ,,thereof--,,luminosity ,,of ,,the ,,ocean4 ,reference has elsewhere been made in this volume to the immense amount of animal life that exists in the ocean1 not only in the form of fish of all sizes1 but in that of animalcules1 which1 although scarcely visible to the naked eye1 are1 in some cases1 so innumerable as to give a distinct colouring to the water4 ,the ,medusae1 or1 more familiarly1 sea blubbers1 are seen in the waters that lave our own shores4 ,they are of various sizes1 from that of a large plate to a pin-head4 ,they are almost colourless1 like clear jelly1 and when carelessly observed1 seem to be dead objects drifting with the tide2 but a closer observation shows that they are possessed of life1 though not of a particularly active kind1 and that they swim by alternate contractions and expansions of their bodies4 ,these creatures constitute a large part of the whale's food4 ,some of them are flat1 some semi-globular1 others are bell-shaped1 while some have got little heads and small fins4 ,of these last it is said that each little creature has no fewer than three hundred and sixty thousand minute suckers on its head with which it seizes its prey4 ,when we think of the exceeding smallness of the creatures thus preyed upon1 and consider the fact that each little thing must obtain food by making war upon some creatures still smaller than itself1 we are led almost in spite of ourselves into that mysteriously metaphysical question--infinitesimal divisibility2 which may be translated thus--the endless division and subdivision of atoms4 ,this subject has puzzled the heads of the profoundest philosophers of all ages2 we will not1 therefore1 puzzle our readers with it any further4 ,scoresby tells us that the colour of the ,greenland ,sea varies from ultramarine blue to olive-green1 from the purest transparency to striking opacity2 and that these colours are permanent1 and do not depend on the state of the weather1 but on the quality of the water4 ,he observed that whales were found in much greater numbers in the green than in the blue water2 and he found1 on examining the former with the microscope1 that its opacity and its colour were due to countless multitudes of those animalcules on which the whale feeds4 ,we need scarcely remark that it is utterly beyond the power of man to form anything approaching to a correct conception of the amount of life that is thus shown to exist in the ocean4 ,although it has pleased the ,creator to limit our powers1 yet it has also pleased him to leave the limit of those powers undefined4 ,we may not1 indeed1 ever hope in this life to attain to perfect knowledge1 nevertheless1 by searching we may find out wisdom2 and certain it is1 that1 although there undoubtedly must be a point of knowledge on any given subject which man cannot reach1 there is in man a power incessantly to extend his knowledge and increase his powers of conception1 by each successive effort that he makes in his course from the cradle to the grave4 ,even although we were told the exact number of the little creatures that inhabit the sea1 we could not1 by any simple effort of the mind1 however powerful1 form a conception of what that number implied4 ,we might shut ourselves up like the hermits of old1 abstract our thoughts from all other things1 and ponder the subject for weeks or months together1 and at the termination of our effort we should be as wise as we were at its commencement1 but no wiser4 ,but by searching round the subject1 and comparing lesser things with greater1 although we should still fail to arrive at a full comprehension of the truth1 we may advance our powers of conception very considerably beyond the point attained by our first effort2 and which point1 as we have said1 could not be surmounted by a hair's breadth by the mere exertion of simple or abstract thought4 ,dr ,scoresby's remarks on the subject of animal life in the ocean1 are so graphic and curious that we extract the passages verbatim from the admirable memoir of that gentleman1 written by his nephew4 ,he says3 ,i procured a quantity of snow from a piece of ice that had been washed by the sea1 and was greatly discoloured by the decomposition of some peculiar substance upon it4 ,a little of this snow dissolved in a wine-glass appeared perfectly nebulous--the water being found to contain a great number of semi-transparent spherical substances1 with others resembling small portions of fine hair4 ,on examining these substances with a compound microscope1 ,i was enabled to make the following observations3-- ,the semi-transparent globules appeared to consist of an animal of the medusa kind4 ,it was from one-twentieth to one-thirtieth of an inch in diameter4 ,its surface was marked with twelve distinct patches1 or nebulae1 of dots of a brownish colour4 ,these dots were disposed in pairs1 four pairs or sixteen pairs alternately1 composing one of the nebula4 ,the body of the medusa was transparent4 ,when the water containing these animals was heated1 it emitted a very strong odour1 in some respects resembling the smell of oysters when thrown on hot coals1 but much more offensive4 ,the fibrous or hair-like substances were more easily examined1 being of a darker colour4 ,they varied in length from a point to one-tenth of an inch2 and when highly magnified1 were found beautifully moniliform4 ,whether they were living animals1 and possessed of locomotion1 ,i could not ascertain4 ,they possessed the property of decomposing light1 and in some cases showed all the colours of the spectrum very distinctly4 ,i afterwards examined the different qualities of sea water1 and found these substances very abundant in that of an olive-green colour2 and also occurring1 but in lesser quantity1 in the bluish-green water4 ,the number of medusae in the olive-green water was found to be immense4 ,they were about one-fourth of an inch asunder4 ,in this proportion1 a cubic inch of water must contain #fd2 a cubic foot #aaj1eib2 a cubic fathom #bc1hhg1hgb2 and a cubic mile about #bc1hhh1jjj1jjj1jjj1jjj4 ,of course we have1 in the last two numbers1 reached the utterly incomprehensible2 but ,dr ,scoresby goes into comparisons which help us a little1 at least to ascertain how hopelessly beyond our conceptions such numbers are4 ,from soundings made in the situation where these animals were found1 it is probable the sea is upwards of a mile in depth2 but whether these substances occupy the whole depth is uncertain4 ,provided1 however1 the depth to which they extend be but two hundred and fifty fathoms1 the above immense number of one species may occur in the space of two miles square4 ,it may give a better conception of the amount of medusae in this extent1 if we calculate the length of time that would be requisite1 with a certain number of persons1 for counting this number4 ,allowing that one person could count a million in seven days1 which is barely possible1 it would have required that eighty thousand persons should have started at the creation of the world to complete the enumeration at the present time6 ,what a stupendous idea this gives of the immensity of creation1 and of the bounty of ,divine ,providence in furnishing such a profusion of life in a region so remote from the habitations of men6 ,the larger portion of these medusae1 consisting of transparent substances of a lemon-yellow colour1 and globular form1 appeared to possess very little power of motion4 ,some of them were seen advancing by a slight waving motion1 at the rate of a hundred and eightieth of an inch in a second2 and others1 spinning round with considerable celerity1 gave great interest and liveliness to the examination4 ,but the progressive motion of the most active1 however distinct and rapid it might appear under a high magnifying power1 was1 in reality1 extremely slow2 for it did not exceed an inch in three minutes4 ,at this rate they would require one hundred and fifty-one days to travel a nautical mile4 ,the vastness of their numbers1 and their exceeding minuteness1 are circumstances1 discovered in the examination of these animalcules1 of uncommon interest4 ,in a drop of water examined by a power of #bh4bbd 7magnified superficies7 there were fifty in number1 on an average1 in each square of the micrometer glass1 of an eight hundred and fortieth of an inch2 and as the drop occupied a circle on a plate of glass containing #ebi of these squares1 there must have been1 in this single drop of water1 taken out of the yellowish-green sea1 in a place by no means the most discoloured1 about #bf1dej animalcules4 ,hence1 reckoning sixty drops to a dram1 there would be a number in a gallon of water exceeding1 by one half the amount of the population of the whole globe6 ,it gives a powerful conception of the minuteness and wonders of creation1 when we think of more than twenty-six thousand animals living1 obtaining subsistence1 and moving perfectly at their ease1 without annoyance to one another1 in a single drop of water444 ,a whale requires a sea1 an ocean1 to sport in4 ,about one hundred and fifty millions of these animalcules would have abundant room in a tumbler of water6 ,but besides furnishing food to the whale1 and1 no doubt1 to many other of the inhabitants of the deep1 those medusae are the cause of the phosphorescent light that sometimes glows on the ocean with resplendent brilliancy4 ,we see this light oftentimes on our own coasts4 ,it is usually of a pale bluish-white colour1 more or less intense1 apparently1 according to the condition of the creatures by which it is emitted4 ,it can only be seen at night4 ,we have seen it on the west coast of ,scotland1 so bright that the steamer in which we sailed left behind her what appeared to be a broad highway of liquid fire4 ,at times it requires vigorous motion1 such as takes place when an oar is dipped1 a stone thrown1 or paddle-wheels dashed into the water2 but at other times1 the mere motion of the ocean swell1 even in calm weather1 is sufficient to stir up the lambent light and cause the crest of every undulation to glitter as if tipped with burnished silver4 ,in such circumstances we have seen the ends of the oars of a boat silvered with it when lifted out of the wave1 and the drops which fell from them before being redipped resembled the most beautiful diamonds4 ,mr ,p4,h4 ,gosse1 in his interesting work1 ,the ,ocean1 gives the following account of this luminosity of the sea1 as witnessed by himself on one occasion3 ,in a voyage to the ,gulf of ,mexico1 ,i saw the water in those seas more splendidly luminous than ,i had ever observed before4 ,it was indeed a magnificent sight1 to stand on the fore-part of the vessel and watch her breasting the waves4 ,the mass of water rolled from her bows as white as milk1 studded with those innumerable sparkles of blue light4 ,the nebulosity instantly separated into small masses1 curdled like clouds of marbles1 leaving the water between of its own clear blackness2 the clouds soon subsided1 but the sparks remained4 ,sometimes one of these points1 of greater size and brilliancy than the rest1 suddenly burst into a small cloud of superior whiteness to the mass1 and be then lost in it4 ,the curdling of the milky appearance into clouds and masses1 and its quick subsidence1 were what ,i had never before observed elsewhere4 ,many scientific travellers have carefully examined this subject1 and we believe that all agree in referring this beautiful appearance to the medusae4 ,one gentleman drew a bucketful of water from the sea when it was in this condition1 and found1 on examining it in a dark place1 that the little creatures could be distinctly seen emitting a bright speck of light4 ,sometimes this was like a sudden flash1 at others appearing like an oblong or round luminous point1 which continued bright for a short time1 like a lamp lit beneath the water and moving through it1 still possessing its definite shape1 and then suddenly disappearing4 ,when the bucket was sharply struck on the outside1 there would appear at once a great number of these luminous bodies1 which retained their brilliant appearance for a few seconds1 and then all was dark again4 ,they evidently appeared to have it under their own will1 giving out their light frequently1 at various depths in the water1 without any agitation being given to the bucket4 ,at times might be seen minute but pretty bright specks of light1 darting across a piece of water and then vanishing2 the motion of the light being exactly that of the cyclops through the water4 ,upon removing a tumblerful from the bucket1 and taking it to the light1 a number of cyclops were accordingly found swimming and darting about in it4 ,we have given the above quotation at full length1 because it proves1 in an interesting manner1 the fact that phosphorescence1 or luminosity1 of the sea is actually produced by multitudes of living creatures4 ,we cannot pass from it1 however1 without expressing our difference of opinion in regard to the power of the medusae to emit their light at will4 ,it seems much more probable that the light is the result of passion and action4 ,when a man's feelings are strongly roused1 whether pleasurably or otherwise1 he usually starts into action under a sudden impulse1 which sends the blood violently through his veins1 causing his face to become flushed and red4 ,this reddening is not the result of will4 ,it is the unavoidable result of passionate impulse1 and could not possibly be produced by an effort of the will4 ,it is well known that electric fluid permeates the bodies of all animals1 more or less2 and it is quite conceivable that under the influence of nervous impulse one creature should become luminous1 while another only becomes red4 ,man leaps and sings for joy2 and the result is1 that the actions cause his countenance to glow with colour4 ,the marine animalcule1 experiencing a sudden influx of delight1 darts hither and thither under the strong impulse of its exuberant glee2 and the result is1 that its little body gleams with light4 ,vigorous action is the direct cause of the emission of light in the one case1 just as vigorous action is the direct cause of the suffusion of the countenance in the other4 ,but in both cases the primary cause is passion--at least so it seems to us4 ,no doubt fear as well as joy may create vigorous action1 and produce the same result2 but as we know that1 as a general rule1 there is much more of joy than of fear dwelling at all times in the hearts of ,god's creatures1 we can well believe that the amount of luminosity produced in the sea by the latter passion is immeasurably smaller than that produced by the former4 ,we are thus1 therefore1 set free to indulge in the pleasing reflection that when we behold that magnificent gleaming of the sea1 which almost resembles liquid silver reflecting the stars of heaven1 we are witnessing the frolicsome and joyous gambols of those myriads of little beings to whom the beneficent ,creator has assigned the ocean as their dwelling-place4 ,the theory which we have ventured to propound in regard to vigorous impulse 7whether of joy or fear7 being the cause of eliciting luminosity1 is supported in some degree by the remark in our last quotation1 that when the bucket was sharply struck1 there appeared at once a number of luminous bodies1 which shone for a few seconds1 and then disappeared4 ,undoubtedly the poor little things got a fright when their residence was sharply assailed in such an unusual manner2 their energies were roused1 and their light emitted4 ,then1 as they gradually calmed down1 their light disappeared4 ,we are further told that when a drop of sulphuric acid was put into a tumbler of water1 several bright flashes were seen4 ,this1 we venture to think1 was somewhat similar to the putting of a few drops of brandy and water into the human stomach2 the usual result of which is1 as we all know1 to produce several bright flashes of wit1 if not of light1 or of something at least meant to be remarkably luminous6 ,but this luminosity is not entirely confined to the minute creatures of the sea4 ,some fish have the power of emitting light4 ,some species of the shark emit a greenish light2 and the sun-fish is said1 when seen down in the sea on a dark night1 to glow like a white-hot cannon-ball4 ,fish when dead and putrid frequently glow in the dark with a truly magnificent light1 as can be proved by every one who will take the trouble to procure several kinds of fish1 and keep them1 for the purpose of proving the fact1 in a dark closet4 ,of all the minute inhabitants of the deep1 that which is to our mind the most curious1 both as to its nature and its stupendous works1 is the coral insect4 ,this creature is much too important to be dragged in at the tail of a chapter4 ,we will1 therefore1 commence its history in a new one4 ,,chapter ,,fifteen4 ,,coral ,,insects ,,and ,,coral ,,islands--,,polynesia--,,operations ,,of ,,the ,,coral ,,insect--,,growth ,,of ,,coral ,,reefs4 ,many of the large and beautiful islands that stud the ,pacific ,ocean1 like emeralds in a field of blue1 are artificial2 that is to say1 they were made by artists--they were actually built by artisans6 ,these artisans are the coral insects2 and as they not only affect the face of the sea by raising large islands above it1 but also1 in consequence of their labours1 assist in causing the circulation of the ocean1 we think they are justly entitled to very special attention4 ,the great archipelago called ,polynesia covers an area of the ,pacific nearly #ejjj miles in length1 and not far short of #bjjj in breadth4 ,some of the islands of this group are of volcanic origin1 and some are crystal2 but by far the greater number are of coral formation--the work of those curious little insects1 which are so small that they inhabit a dwelling sometimes little larger than a pin-point4 ,the manner in which these islands are made is1 to some extent1 a matter of uncertainty4 ,the most generally received opinion is1 that the insects fasten round the summit of a submarine mountain1 and build upwards until they reach the surface of the sea1 where they die1 and their labours cease4 ,as1 however1 the sea is sometimes unfathomable close to those islands1 it has been supposed that the submarine islands on which the corallines began to build have gradually subsided1 and that1 as they did so1 the insects always built a little more1 so as to keep the top of their structures on a level with the sea4 ,above the sea they cannot build4 ,to be washed by the waves is essential to their existence4 ,we do not think this a very satisfactory theory1 because it supposes a prolonged subsiding of these islands1 and then an unaccountably sudden stoppage4 ,for although the corallines might continue to build during the whole time of subsidence1 it were utterly impossible that the coral island1 with its luxuriant herbage1 could be formed until that subsidence should have ceased4 ,the manner in which the islands are formed makes this obvious4 ,when the coral reef1 as it is called1 reaches the surface1 it advances no further4 ,soon the action of the waves breaks off the branches of the upper portions of coral1 which are tossed upon the reef1 and pulverised into fine sand4 ,this goes on increasing until the island rises a little above the waves4 ,when this happens1 birds alight there2 sea-drift is carried thither2 seeds are blown to it by the wind2 and gradually a few green blades arise4 ,from this little beginning it is easy to conceive the process by which at last a flourishing island springs up4 ,at the same time1 it is not easy to see how such islands could ever be formed on the supposition that the submarine rocks on which they were founded were perpetually subsiding4 ,but be that as it may1 we have no difficulty in understanding the fact that the coral insect does build those islands4 ,it possesses the power of secreting the lime held in solution by sea water1 and depositing the same on the rocks below the waves4 ,the coral rock is the edifice of the coralline4 ,the insect itself is a soft and very minute worm1 which1 when washed by the waves1 thrusts its head out of its tiny little door1 and spreading abroad its numerous feelers1 so that it resembles a beautiful little star1 moves these about as if enjoying itself--though1 doubtless1 it is actually engaged in the process of manufacturing its little atom of coral rock4 ,it is extremely interesting to think of the immense power of union thus exhibited4 ,singly1 those little creatures could not produce a sufficient result to attract the attention of any creature save such as chanced to come in direct and close contact with its little cell4 ,united1 they have formed vast islands1 which have become the abode of man1 and which1 in the aggregate1 form no inconsiderable portion of the globe4 ,the consideration of this leads us to perceive that ,god has ordained that units cannot1 separately1 accomplish much2 and that united effort1 in order to be successful1 requires the harmonious action of units4 ,a house divided against itself cannot stand4 ,the innumerable and eminently beautiful isles of the ,pacific had never stood where they now stand if the curious1 and separately insignificant1 little architects that reared them had not wrought unitedly upon a fixed and systematic plan--each insect working its utmost from the hour of its birth until that of its death4 ,there are various kinds of coral insects1 which form varied species of coral rock4 ,some kinds of coral assume the form of rounded masses2 some are like a branching shrub2 others are in layers1 or thin plates2 and some are shaped like the human brain1 from which they derive their name--brainstones4 ,these different kinds differ also in colour1 and thus present a beautiful appearance when seen at the bottom of clear and shallow water4 ,in regard to the rate at which the corallines build their cells there is some diversity of opinion--some asserting that the process is imperceptible1 while others state as positively that it is rapid4 ,there can be no doubt that some localities and positions are more favourable to the growth of coral than others4 ,dr ,allan1 while at ,madagascar1 made several experiments to test this4 ,he selected several masses of coral1 each weighing about ten pounds1 and of different species4 ,these he placed three feet below the surface of the sea1 and staked them in to prevent removal4 ,in a little more than six months they were found to have risen nearly to the surface1 and to have attached themselves to the solid rock4 ,there is also a case mentioned of a ship in the ,persian ,gulf which1 in the course of twenty months1 had her copper encased with living coral to the thickness of two feet4 ,on the other hand1 it is asserted1 and we doubt not with equal truth1 that many reefs do not seem to increase in size in the course of many years4 ,when a coral reef has reached the surface1 the formation of an island instantly begins2 but it necessarily takes a long time ere this island becomes habitable by man4 ,among the first plants that raise their heads to the sea-breeze is the graceful cocoa-nut palm4 ,this tree is exceedingly hardy1 and is found growing on reefs which are so low that at a distance the trees seem to be standing on the surface of the water4 ,indeed many of them spring out of the pure white sand1 and their roots are washed perpetually by the salt spray4 ,nevertheless1 the fruit of such trees is sweet and good4 ,coral islands of the kind we have just described seldom rise more than a few feet above the level of the sea2 but most of them are clothed with luxuriant vegetation4 ,we might easily fill a volume on the subject of the ocean's inhabitants1 small and great2 but we think the few to which we have made reference is sufficient for the purpose of showing that one set of creatures accounts for that strange luminosity of the ocean which is seen at times in all marine parts of the globe1 while another set accounts not only for the sudden appearance of coral islands in the sea where no such islands existed in days of old1 but also1 partly1 for that circulation of the waters of the ocean which is absolutely necessary to the wellbeing of all the creatures on this earth4 ,there are other animals in the sea1 besides medusae1 which assist in giving luminosity to its waters2 and there are other insects1 besides corallines1 which extract its lime1 destroy its equilibrium1 and assist in causing its perpetual motion2 but the two species which we have described are the best types of the respective classes to which they belong4 ,,chapter ,,sixteen4 ,,volcanic ,,islands--,,opinions ,,of ,,the ,,ancients--,,atlantis--,,instance ,,of ,,the ,,formation ,,of ,a ,,volcanic ,,island--,,conclusion4 ,in the last chapter we described the manner in which a certain class of islands in the ,south ,seas are formed2 in the present we will make a few observations on another class1 which have sprung up from the bottom of the sea1 as if by magic1 under the irresistible influence of fire4 ,there are volcanoes in the sea1 as well as on the land2 and these volcanoes have in former times up-heaved huge masses of land so as to form large islands1 while in other cases they have caused islands formerly in existence to subside and disappear4 ,in the writings of the ancients we find reference made to an island which1 if it ever did exist1 now exists no longer4 ,it was situated opposite the ,straits of ,gibraltar1 was nearly two hundred miles in length1 and was called ,atlantis--hence the name of the ,atlantic ,ocean4 ,many believe1 and with some reason1 we think1 that this island was not altogether a myth1 although much that is said of it is undoubtedly fabulous4 ,plato tells us that it was a large island in the ,western ,ocean1 situated before or opposite to the ,straits of ,gades2 and that out of this island there was an easy passage into some others which lay near a large continent1 exceeding in bigness all ,europe and ,asia4 ,so far ,plato may have told the truth1 and from this passage it is conjectured that the existence of the continent of ,america was known to the ancients4 ,but he goes on1 immediately after1 to draw upon his imagination1 and to tell us that ,neptune settled on this island1 and that his posterity dwelt there for a period of nine thousand years in the midst of fertility and abundance4 ,but1 not content with their ample possessions and prolific soil1 they went over to ,africa and ,europe1 and even penetrated into ,asia1 bent on conquest4 ,passing from this mixture of probable truth and undoubted fable1 ,plato then asserts that the island of ,atlantis finally sank and disappeared4 ,this may or may not be true1 but there is more reason for our crediting the statement than many people would suppose4 ,certain it is that no such island exists at the present time1 but it is believed by some that the ,azores1 which are volcanic in their formation1 are the summits of the mountain ranges of the ,atlantis of the ancients4 ,but the best evidence we have of the possible existence of such an island is the fact that in modern times an island has been seen to rise out of the sea1 and1 after a time1 to disappear1 under the influence of volcanic action4 ,this remarkable event is related by ,captain ,tillard1 an officer of the ,british ,navy1 who saw it on the #abth of ,june #ahaa1 when approaching the island of ,st4 ,michael4 ,on this occasion smoke was seen to rise from the surface of the sea1 and1 soon after1 showers of cinders to burst forth4 ,we cannot do better than give the captain's own words1 as follows3 ,imagine an immense body of smoke rising from the sea1 the surface of which was marked by the silvery rippling of the waves4 ,in a quiescent state it had the appearance of a circular cloud revolving on the water1 like a horizontal wheel1 in various and irregular involutions1 expanding itself gradually on the lee side2 when1 suddenly1 a column of the blackest cinders1 ashes1 and stones1 would shoot up in the form of a spire1 at an angle of from ten to twenty degrees from a perpendicular line1 the angle of inclination being universally to windward4 ,this was rapidly succeeded by a second1 third1 and fourth shower1 each acquiring greater velocity1 and overtopping the other1 till they had attained an altitude as much above the level of our eye as the sea was below it4 ,as the impetus with which the several columns were severally propelled diminished1 and their ascending motion had nearly ceased1 they broke into various branches resembling a group of pines4 ,these again formed themselves into festoons of white feathery smoke1 in the most fanciful manner imaginable1 intermixed with the finest particles of falling ashes2 which at one time assumed the appearance of innumerable plumes of black and white ostrich feathers surmounting each other2 at another1 that of the light wavy branches of a weeping willow4 ,during these bursts the most vivid flashes of lightning continually issued from the densest part of the volcano2 and the cloud of smoke now ascending to an altitude much above the highest point to which the ashes were projected1 rolled off in large masses of fleecy clouds1 gradually expanding themselves before the wind1 in a direction nearly horizontal1 and drawing up to them a quantity of water-spouts1 which formed a most beautiful and striking addition to the general appearance of the scene4 ,such is the description given of this submarine volcano in action2 and the crater which was thrown up at the time was about twenty feet above the level of the sea4 ,as ,captain ,tillard could not1 however1 delay his voyage to make further observations at that time1 the action that subsequently took place is not known2 but its results were seen shortly afterwards4 ,in about three weeks after the date of his passing the spot1 ,captain ,tillard returned to it and found an island of about a mile in circumference1 with a height of between two and three hundred feet at its highest point4 ,there was no violent eruption going on1 although the craters still emitted smoke4 ,he therefore landed1 and1 on reaching the largest crater1 found it to be full of boiling water1 which overflowed and found its way to the ocean in a river of about six yards in width4 ,this island1 however1 was not a permanent addition to the world's archipelago4 ,it sank into the ocean again1 and disappeared in ,october of the same year in which it rose4 ,in commencing this little book we set out with the intention of rambling hither and thither1 among things that relate to the sea1 without regard to order4 ,we have carried out our intention2 and now1 at the close of our task1 find that the more we listen to the ,ocean's ,voice1 the more we find its tale to be interminable1 though the reverse of uninteresting4 ,in these rambles we have sought to treat chiefly of those scientific facts relating to the sea and the atmospheric ocean1 which are not so frequently made the subject of books for the young1 as are the wild and daring deeds of man upon the surface of the mighty deep4 ,it is not sufficient that man should become acquainted with the doings of his fellows on the sea4 ,this is but one branch of general knowledge1 and a very secondary one compared with that infinitely higher branch which treats of the workings of the ,almighty in the ocean2 workings which render it what it is--not merely a means of commercial enterprise for man and a home for fish1 but also a great purifier and revivifier of the earth and sweetener of the atmosphere4 ,god is the great first cause of all that is and that operates in the universe4 ,it were an act of presumption to inquire into what we may term the first acts of the ,almighty's power4 ,but there is no presumption--on the contrary there is propriety1 as well as the highest gratification of which the human mind is capable--in penetrating through the paths of knowledge up to that first series of second causes which circle like a glory round the fountain-head4 ,we may not put the question1 ,how did ,god create all things out of nothing8 but1 all things having been created1 it is quite legitimate to inquire how the circles of their manifold operations are carried on1 and in what respect the things that be do affect each other4 ,no book that has of late years issued from the press treats more eloquently and interestingly of such subjects of inquiry than that admirable work of ,captain ,maury of the ,united ,states ,navy1 entitled ,the ,physical ,geography of the ,sea4 ,much of the substance of what we have written has been culled from the pages of that fascinating volume4 ,but we have merely plucked one or two leaves1 as it were1 and presented them to our readers in the hope that they may be tempted by their fragrance to pluck the flower4 ,the mysteries of the atmospheric and aqueous oceans are here treated of fully1 yet so agreeably1 that one is frequently apt to fancy one is perusing the pages of romance4 ,in our own little book we have been compelled to skim lightly1 and1 in many places1 to pass over subjects of great interest4 ,as for other subjects connected with the sea1 of which we may not treat1 they are innumerable4 ,of the sea-weeds that clothe the bottom of the deep with the rich profusion and glowing colours of the gardens of earth--of the myriads of animalcules 7besides those we have mentioned7 that disport in its waters and fill the abyss with life and lambent fire--of the great whales and other huge creatures that revel in its depths and lash its waters in their terrible might--of these and a host of kindred subjects1 our space forbids our saying more than that the ,voice of ,ocean has much to tell us in regard to them1 and in regard to the provident care of their beneficent ,creator4
