slight variation from the original text1 the words of ,thomas ,jefferson about ,benjamin ,franklin and his maligners1 quoted in the body of this monograph1 apply to this case3 ,i have seen with extreme indignation the blasphemies lately vended against the memory of the father of the ,american plow4 ,but his memory will be venerated as long as furrows are turned and soil tilled4 ,the present object1 however1 is not so much to refute falsehood as to establish the truth1 and make it a part of the permanent knowledge of the public4 ,to the extent that this object shall be attained1 will these labors be rewarded4 ,it is not the design of this publication to disparage any one2 on the contrary1 it is desired to give ample credit to all who contributed to the solution of the plow problem4 ,if only brief mention is made of others1 it is because they really deserved but little credit1 or their merits are forever buried in obscurity4 ,it is proposed to set forth without exaggeration1 the claims of the supreme inventor in this line to the grateful remembrance of the public4 ,and by the public is meant not only the ,american people1 but all who are fed from the ample granaries of this country1 or share the benefits of the improved tillage1 whether on this continent or in ,europe1 made possible and actual by the inventive genius of ,jethro ,wood4 ,,jethro ,,wood2 ,,inventor ,,of ,,the ,,modern ,,plow4 ,the last words ever penned by ,john ,quincy ,adams were these1 written in the peculiarly tremulous hand of the ,old ,man ,eloquent3 ,mr4 ,j4 ,q4 ,adams presents his compliments to the ,misses ,wood1 and will be happy to see them at his house1 at their convenience1 any morning between #aj and #aa o'clock4 ,this note was found upon his desk when he was stricken down with paralysis1 ,february #ba1 #ahdh1 in his seat in the ,house of ,representatives4 ,the ,misses ,wood here referred to were the daughters of ,jethro ,wood1 then deceased4 ,they were at that time engaged in a labor of love1 and the venerable ,ex-,president was their friend therein4 ,prompted more by filial affection than by hope of gain1 they were making a final effort to secure from ,congress a proper recognition of their father's claim as an inventor4 ,it is entirely safe to say that if ,mr4 ,adams had been spared to the end of the ,congress then in session1 that claim would have been then duly recognized1 and the name1 services and genius of ,jethro ,wood become familiar to the ,american public4 ,jethro ,wood was born at ,dartmouth1 ,massachusetts1 on the sixteenth day of the third month of #aggd4 ,his parents were members of the ,society of ,friends4 ,his mother1 ,dinah ,hussey ,wood1 was a niece of ,ann ,starbuck1 a woman of remarkable ability and high standing in colonial annals4 ,ann ,starbuck was virtually governor of ,nantucket4 ,the niece was a woman of excellent intellect1 and most winsome character4 ,her conversation sparkled with genial wit and good cheer4 ,her husband1 ,john ,wood1 was a man of sterling worth1 calm1 self-poised1 strong willed1 and eminently influential4 ,jethro was their only son4 ,on ,new ,years ,day1 #agic1 he was married to ,sylvia ,howland1 at ,white ,creek1 ,washington ,county1 ,new ,york4 ,the fruit of this marriage1 every way a happy one1 was a family of six children1 namely3 ,benjamin2 ,john2 ,maria1 wife of ,jeremiah ,foote2 ,phoebe2 ,sarah1 wife of ,robert ,r4 ,underhill2 ,sylvia ,ann1 wife of ,benjamin ,gould4 ,of these children the only survivor is ,mrs4 ,gould1 who with her sister1 ,phoebe1 were the ,misses ,wood of the ,adams note4 ,so much for the domestic setting of this diamond of inventive genius4 ,even as a boy1 ,jethro ,wood showed plainly the drift and trend of his mind4 ,the child was indeed father of the man1 and almost from the cradle to the grave1 he was an inventor4 ,in his childish plays he seemed busied with the idea which he ultimately perfected4 ,many curious incidents and memories are treasured among the traditions of his neighbors and friends4 ,when only a few years old1 writes a venerable man whose recollection spans two generations1 he moulded a little plow from metal1 which he obtained by melting a pewter cup4 ,then1 cutting the buckles from a set of braces1 he made a miniature harness with which he fastened the family cat to his tiny plow1 and endeavored to drive her about the flower-garden4 ,the good old-fashioned whipping he received for this 'mischief1' was such as to drive all desire for repeating the experiment out of his juvenile head4 ,such innate and ruling passion might be suppressed1 but could not be subdued4 ,as his mind matured1 his thoughts took definite shape4 ,his home was always upon a farm1 but he was never a farmer1 in the sense of ,poor ,richard's homely couplet3 ,he who by the plow would thrive1 ,himself must either hold or drive4 ,born in comparative affluence1 blessed with a good education1 an ample library and a well equipped workshop1 enjoying the correspondence of such men as ,thomas ,jefferson and ,david ,thomas1 he was unremitting in his endeavor to realize his ideal4 ,his chief desire1 to quote further from our venerable correspondent1 was to invent a new mold-board1 which1 from its form1 should meet the least resistance from the soil1 and which could be made with share and standard1 entirely of cast iron4 ,to hit upon the exact shape for the mold-board he whittled away1 day after day1 until his neighbors1 who thought him mad on the subject1 gave him the soubriquet of the whittling ,yankee4 ,his custom was to take a large oblong potato which was easy for the knife1 and cut it till he obtained what he fancied was the exact curve4 ,the manhood home of ,jethro ,wood was at ,scipio1 ,cayuga ,county1 ,new ,york1 a purely agricultural town1 with nothing in its later history to distinguish it2 but in its palmier early days of the present century1 it must have been a nursery of invention4 ,roswell ,toulsby1 ,horace ,pease1 and ,john ,swan1 of that town1 each took out letters patent for improvements in plows1 and that prior to the issuance of any patent to ,mr4 ,wood4 ,their improvements were of no practical value1 and played no part in the development of this branch of mechanism1 but their efforts serve to show the state of the intellectual atmosphere breathed by the man who was destined to solve the knotty problem which underlies the very foundation of scientific agriculture4 ,of the cotemporaries of ,mr4 ,wood1 who wrought at the solution of this problem1 the most illustrious was ,thomas ,jefferson1 statesman1 philosopher and farmer4 ,in one of his letters to ,jethro ,wood1 ,mr4 ,jefferson spoke of his own labors in that direction1 as the experiments of one whiling away a few idle hours1 but herein he did himself injustice4 ,his efforts1 however1 were far from exhaustive in their results1 and it was with good reason that he urged ,mr4 ,wood to go forward in his undertaking1 and no doubt he was perfectly sincere in wishing him success4 ,his correspondence1 as published in nine large volumes1 attests his long and deep interest in the problem1 which it was reserved for ,jethro ,wood to solve4 ,having carefully examined those volumes1 to glean all there is in them on this subject1 ,i herewith append the observations found1 for besides being in themselves interesting1 in view of their authorship1 they throw important light upon the general subject4 ,under date of ,july #c1 #agif1 ,mr4 ,jefferson wrote to ,jonathan ,williams3 ,you wish me to present to the ,philosophical ,society the result of my philosophical researches since my retirement4 ,but1 my good ,sir1 ,i have made researches into nothing but what is connected with agriculture4 ,in this way ,i have a little matter to communicate1 and will do it ere long4 ,it is the form of a mould-board of least resistance4 ,i had some years ago conceived the principle of it1 and ,i explained it then to ,mr4 ,rittenhouse4 ,i have since reduced the thing to practice1 and have reason to believe the theory fully confirmed4 ,i only wish for one of those instruments used in ,england for measuring force exerted in the drafts of different ploughs1 etc41 that ,i might compare the resistance of my mould-board with that of others4 ,but these instruments are not to be had here4 ,in a letter of this date to ,mr4 ,rittenhouse ,i mention a discovery in animal history1 very signal indeed1 of which ,i shall lay before the society the best account ,i can1 as soon as ,i shall have received some other materials collecting for me4 ,i have seen1 with extreme indignation1 the blasphemies lately vended against the memory of the father of ,american philosophy4 ,but his memory will be venerated as long as the thunder of heaven shall be heard or feared4 ,march #bg1 #agih1 ,jefferson wrote to ,mr4 ,patterson3 ,in the life time of ,mr4 ,rittenhouse1 ,i communicated to him the description of a mould-board of a plough1 which ,i had constructed1 and supposed to be what we might term the mould-board of least resistance4 ,i asked not only his opinion1 but that he would submit it to you also4 ,after he had considered it he gave me his own opinion that it was demonstratively what ,i had supposed1 and ,i think he said he had communicated it to you4 ,of that however1 ,i am not sure1 and therefore1 now take the liberty of sending you a description of it1 and a model which ,i have prepared for the ,board of ,agriculture of ,england1 at their request4 ,mr4 ,strickland1 one of their members1 had seen the model1 also the thing itself in use on my farm1 and thinking favorably of it1 had mentioned it to them4 ,my purpose in troubling you with it is to ask you to examine the description rigorously1 and suggest to me any corrections or alterations which you may think necessary4 ,i would wish to have the idea go as correctly as possible out of my hands4 ,i had sometimes thought of giving it into the ,philosophical ,society1 but ,i doubted whether it was worthy of their notice1 and supposed it not exactly in the line of their publications4 ,i had therefore contemplated sending it to some of our agricultural societies1 in whose way it was more particularly1 when ,i received the request of the ,english board4 ,the papers ,i enclose you are the latter part of a letter to ,sir ,john ,sinclair1 their president4 ,it is to go off by packett1 wherefore ,i wish to ask the favor of you to return them with the model in the course of the present week1 with any observations you will be so good as to favor me with4 ,writing from ,washington1 ,july #ae1 #ahjh1 to ,mr4 ,sylvestre1 in acknowledgment of a plow received from the ,agricultural ,society of the ,seine 7,france71 he adds3 ,i shall with great pleasure attend to the construction and transmission to the society of a plough with my mould-board4 ,this is the only part of that useful instrument to which ,i have paid any particular attention4 ,but knowing how much the perfection of the plough must depend1 #ast1 on the line of traction2 #b;d1 on the direction of the share2 #c;d1 on the angle of the wing2 #dth1 on the form of the mould-board2 and persuaded that ,i shall find the three first advantages eminently exemplified in that which the society sends me1 ,i am anxious to see combined with these a mould-board of my form1 in the hope it will still advance the perfection of that machine4 ,but for this ,i must ask time till ,i am relieved from the cares which have more right to all my time--that is to say1 till next spring2 i4 e4 until after the expiration of his second term as ,president of the ,united ,states4 ,the importance of any step in civilization can be understood only in its relations1 antecedent causes and actual results4 ,the ,scientific ,american1 which is certainly good authority in such matters1 ranks ,jethro ,wood with ,benjamin ,franklin1 ,eli ,whitney1 ,robert ,fulton1 ,charles ,goodyear1 ,samuel ,b4 ,morse1 ,elias ,howe1 and ,cyrus ,h4 ,mc,cormick1 and these are certainly the great names and this a just classification4 ,each in his way laid the foundation on which all inventors in his respective line have built1 and must continue to build1 and none of them all came so near perfecting his grand idea as ,mr4 ,wood4 ,his now venerable daughter stated the exact truth when she remarked in a letter not designed for publication3 ,my father patented the shape and construction of the plow4 ,he took the iron and shaped the plow that turns the furrow for every product of the soil in ,america4 ,his plow has never been improved4 ,it came from his hand simple and perfect1 as it now is1 and there is no other plow now in use4 ,it was not the use of cast iron that he invented1 although the use of pot metal by him occasioned a great deal of hostility to the original ,wood plow4 ,jethro ,wood took out two plow patents1 and those who wish to belittle his work1 descant upon the first as if it were his only claim to credit4 ,that first patent was issued in #ahad4 ,it fell far short of satisfying the patentee's ambition4 ,the plows made under it must have been a great improvement on any then in use1 for although he abandoned it almost from the first1 a great many of them were sold during the period between the first and the second patents4 ,the second patent dates from #ahai4 ,the natal day of the modern plow may be fairly set down as ,september #a1 #ahai4 ,the original specifications in this plow deserve to be given in full1 and may well be inserted in this connection4 ,the document was the handiwork of ,mr4 ,wood himself1 and runs thus3 ,the ,schedule referred to in these ,letters ,patent1 and making part of the same1 containing a description in the words of the said ,jethro ,wood himself of his improvement in the construction of ,ploughs4 ,considering the manifold errors and defects in the construction of ,ploughs1 and the inconveniences experienced in the use of them1 the petitioner and inventor hath applied the powers of his mind to the improvement of this noble utensil1 and produced a ,plough so far superior to those in common use1 that he asks an exclusive privilege for the same from the government of his country4 ,the principal matters for which he solicits ,letters ,patent1 he now reduces to writing1 and explains in words and sentences as appropriate and significant as he possibly can4 ,but1 being perfectly aware of the feebleness and insufficiency of language to convey precise and adequate ideas of complicated forms and proportions1 the said ,jethro ,wood annexes to these presents1 a delineation upon paper of his said new and improved ,plough1 with full and explanatory notes2 urging with earnestness and respect that the delineation and notes may be considered as a part of this communication4 ,the said petitioner and inventor also1 being perfectly convinced1 as a practical man1 that a model of his inventions and improvements will convey and preserve the most exact and durable impressions of the matters to which he lays claim1 he sends herewith a model of the due form and proportion of each1 as a just exhibition of his principle and of its application to the construction and improvement of the ,plough1 requesting that the same may be kept in the ,patent ,office1 as a perpetual memorial of the invention and its use4 ,in the first place1 the said ,jethro ,wood claims an exclusive privilege for constructing the part of the ,plough1 heretofore1 and to this day1 generally called the mould-board1 in the manner hereinafter mentioned4 ,this mould-board may be termed a plano-curvilinear figure1 not defined nor described in any of the elementary books of geometry or mathematics4 ,but an idea may be conceived of it thus3 ,the land-side of the ,plough1 measuring from the point of the mould-board1 is two feet and two inches long4 ,it is a strait-lined surface1 from four to five and one-half inches wide1 and half an inch thick4 ,its more particular description will be hereinafterwards given4 ,it is sufficient to observe here1 that of the twenty-six inches of length on the land-side1 eighteen inches belong to the part of the ,plough strictly called the land-side1 and eight inches to the mould-board4 ,the part of the mould-board comprehended by this space of eight inches is very important1 affording weight and strength and substance to the ,plough2 enabling it the better to sustain the cutting-edge for separating and elevating the soil or sward1 and likewise the standard for connecting the mould-board with the beam1 as will hereinafter be described more at large4 ,the figure of the mould-board1 as observed from the furrow-side1 is a sort of irregular pentagon1 or five-sided plane1 though curved and inclined in a peculiar manner4 ,its two lower sides touch the ground1 or are intended to do so1 while the three other sides enter into the composition of the oblique1 or slanting mould-board1 over-hanging behind1 vertical midway1 and projecting forward4 ,the angle of the mould-board1 as it departs from the foremost point of1 or at1 the land-side1 is about forty-two degrees1 and the length of it1 or1 in other words1 of the first side1 is eleven inches4 ,the line of the next1 or the second side1 is nearly1 but not exactly parallel with the before-mentioned right-lined land-side1 for it widens or diverges from the angle at which the first and second sides join towards its posterior or hindermost point1 as much as one inch4 ,hence1 the distance from the hindermost point of the mould-board1 at the angle of the second and third sides1 directly across to the land-side1 is one inch more than it is from the angle of the first and second sides1 directly across4 ,the length of this1 the second side1 is eight inches4 ,the next side1 or what is here denominated the third side1 leaves the ground or furrow in a slanting direction backward1 and with an over-hanging curve1 exceeding the perpendicular outwards from three to six inches1 according to the size of the ,plough4 ,the length of this third side is fourteen inches and one-half4 ,the fourth side of this mould-board is horizontal1 or nearly so1 extending from the uppermost point of the third side1 to the fore part1 or pitch1 eighteen inches4 ,the fifth1 or last side1 descends or slopes from the last mentioned mark1 spot1 or pitch1 to the place of beginning at the low and fore point of the mould-board1 where it joins the land-side4 ,its length is thirteen inches4 ,besides these properties and proportions of his mould-board1 the said ,jethro ,wood now explains other properties which it possesses1 and by which it may be and is distinguished from every other invented thing4 ,the peculiar curve has been compared to that of the screw auger2 and it has been likened to the prow of a ship4 ,neither of these similitudes conveys the fair and proper notion of the invention4 ,the mould-board1 which the said ,jethro ,wood claims as his own1 and which is the result of profound reflection and of numberless experiments1 is a sort of plano-curvilinear surface1 as herein-before stated1 having the following bearings and relations3 ,a right line1 drawn by a chalked string or cord1 or by a straight rule1 diagonally or obliquely upwards and backwards from a point two inches and a half inch above the tip or extremity of the mould-board to the angle where the third and fourth sides of the mould-board join1 touches the surface the whole distance1 in an even and uniform application1 and leaves no sinking1 depression1 hole1 cavity1 rising1 lump1 or protuberance1 in any part of the distance4 ,so1 at a distance half way between the diagonal line just described1 and the angle between the first and second sides1 a line drawn parallel to the diagonal line already mentioned will receive the chalked string or cord1 or the straight rule1 as on an uniform and even surface without the smallest bend1 sinuosity1 or bunch1 whereby earth might adhere to the mould-board1 and impede the motion and progress of the ,plough1 under1 through and along the soil4 ,in like manner1 if a point be taken one inch behind the angle connecting the second and third sides1 and a perpendicular be raised upon it1 that perpendicular will coincide with the vertical portion of the mould-board in that place2 or1 in other words1 if a plumb line be let fall so as to reach a point one inch behind the last mentioned angle1 then such a plumb line will hang parallel with the mould-board the whole way2 the line of the mould-board there1 neither projecting nor receding but being both a right line and a perpendicular line4 ,moreover1 if a right line be drawn from a point on the just described perpendicular1 an inch1 or thereabouts1 above the upper margin of the fourth side1 and from the point to which the said perpendicular1 if continued1 would reach2 if1 the said ,jethro ,wood repeats1 a right line be drawn downward and forward1 not exactly parallel to the diagonal herein already described1 but so diverging from the same that it is one inch more distant or further apart1 at its termination on the fifth side of the mould-board1 than at its origin or place of beginning2 such line1 so beginning1 continued1 and ended1 is a right line parallel to the mould-board along its whole course and direction1 and the space over which it passes has no inequality1 hill1 or hollow thereabout4 ,furthermore1 an additional property of his mould-board is1 that1 if it be measured and proved various ways1 vertically and obliquely1 by the saw in fashioning it1 by the rule in meeting it1 and by the chalk-line in determining it1 the capital and distinguishing character of right lines existing on1 over and along the peculiar curve which his mould-board describes1 is always and inseparably present4 ,this grand and discriminating feature of his mould-board1 he considers as of the utmost importance4 ,he therefore craves the aid and elucidation of his drawing1 and of his model1 in their totality and in their several parts1 to render plain and sure whatever there may be1 from the abstruse and recondite nature of the subject1 uncertain or dubious in the language of his specification4 ,in the second place1 the said ,jethro ,wood claims an exclusive right and privilege in the construction of a standard of cast iron1 like the rest of the work already described1 for connecting the mould-board with the beam4 ,this standard is broad1 stout1 strong2 and rises from the fore and upper part of the mould-board1 being cast with it1 and being a projection or continuation of the same from where the fourth and fifth sides meet4 ,its figure1 strength1 and arrangement are such as best to secure the connexion1 and to enable the standard thus associated with the beam1 to bear the pull1 tug1 and brunt of service4 ,by a screw bolt and nut properly adjusted above the top of the standard and acting along its side1 assisted1 if need require1 by a wedge for tightening and loosening1 the beam may be raised and lowered2 and the mould-board1 with its cutting edge1 enabled to make a furrow of greater or smaller depth1 as the ploughman may desire1 and a latch and key fixed to the beam1 and capable of being turned into notches1 grooves1 or depressions on one edge or narrow side of the standard1 serves to keep the beam from settling or descending4 ,by means of these screw bolts1 wedges1 latches1 and keys1 with their appropriate notches1 teeth1 and joggles1 the ,plough may be deepened or shallowed most exactly4 ,in the third place1 the said ,jethro ,wood claims an exclusive privilege in the inventions and improvements made by him in the construction of the cutting edge of the mould-board1 or what may be called1 in plain language1 the plough-share4 ,the cutting edge consists of cast iron1 as do the mould-board and land-side themselves4 ,it is about twelve inches and one half of one inch long1 four inches and one half of one inch broad1 and in the thickest part three quarters of an inch thick4 ,it is so fashioned and cast1 that it fits snugly and nicely into a corresponding excavation or depression at the low and fore edge of the mould-board1 along the side herein before termed the first side4 ,when properly adapted1 the cutting edge seems1 by its uniformity of surface and evenness of connextion1 to be an elongation of the mould-board1 or1 as it were1 an extension or continuation of the same4 ,to give the cutting edge firm coherence and connexion1 it is secured to the mould-board by one or more knobs1 pins or heads in the inner and higher side1 which are received into one or more holes in the fore and lower part of the mould-board4 ,by this mechanism1 the edge is lapped on and kept fast and true1 without the employment of screws4 ,that the cutting edge may be the more securely and immovably kept in its place1 it has a groove1 or ship-lap of one inch in length1 below1 or at its under side1 near the angle between the first and second sides1 for the purpose of holding it1 and for the further accomplishment of the same object1 another groove or ship-lap1 stouter and stronger than the preceding1 is also cast in the iron1 at or near the point of the mould-board1 so as to cover1 encase1 and protect it effectually1 on the upper and lower sides1 but not on the land side4 ,after the cutting edge is thus adapted and adjusted to the mould-board by means of the indentations1 pins1 holes1 ship-laps1 and fastenings1 it is fixed to its place and prevented from slipping back1 or working off1 by wedges or pins of wood1 or other material1 driven into the holes from the inner and under side1 and forced tight home by a hammer4 ,in the fourth place1 the said ,jethro ,wood claims the exclusive right of securing the handles of his plough to the mould-board and land-side of the plough by means of notches1 ears1 loops1 or holders1 cast with the mould-board and land-side respectively1 and serving to receive and contain the handles1 without the use of nuts and screws4 ,for this purpose one or more ears or loops1 or one or more pairs of notches or holders are cast on the inner side of the mould-board and land side1 toward their hinder or back parts1 or near their after margins1 for the reception of the handles of the ,plough4 ,and these1 when duly entered and fitted1 are wedged in1 instead of being fastened by screws4 ,in the fifth place1 the said ,jethro ,wood claims an exclusive right to his invention and improvement in the mode of fitting1 adapting and adjusting the cast iron landside to the cast iron mould-board4 ,their junction is after the manner of tenon and mortice2 the tenon being at the fore end of the land-side and the mortice being at the inside of the mould-board and near its point4 ,the tenon and mortice are joggled1 or dove-tailed together in the casting operation1 so as to make them hold fast4 ,the fore end of the tendon is additionally secured by a cast projection from the inside of the mould-board for its reception2 and if any other tightening or bracing should be requisite1 a wooden wedge1 well driven in1 will bind every part effectually1 and all this is accomplished without the assistance or instrumentality of screws4 ,the said inventor and petitioner wishes it to be understood1 that the principal metallic material of his ,plough is cast iron4 ,he has very little use for wrought iron1 and by adapting the former to the extent he has done1 and by discontinuing the latter1 he is enabled to make the ,plough stronger and better1 as well as more lasting and cheap4 ,he also claims1 and hereby asserts the right1 of varying the dimensions and proportions of his ,plough1 and of its several sections and parts1 in the relations of somewhat more and somewhat less of length1 breadth1 thickness1 and composition1 according to his judgment or fancy1 so that all the while he adheres to his principle and departs not from it4 ,regarding each and every of the matters submitted as very conducive to the reputation and emolument of the said ,jethro ,wood1 he relies confidently upon a benign and favorable construction of his petition and specification1 by the constituted authorities of his country4 ,given under his hand1 at the city of ,new ,york1 this fourteenth day of ,august1 one thousand eight hundred and nineteen 7#ahai71 in the presence of two witnesses1 to wit3 ,,sam',l ,l4 ,,mitchell1 ,j4 ,g4 ,,bogert4 ,,jethro ,,wood4 ,this patent expired by its own limitation in fourteen years1 when it was renewed or continued for another term of fourteen years4 ,in view of the comparative ease and speediness with which the inventors of the present day1 or their assigns1 utilize really valuable patents1 it would be inferred1 in the absence of specific knowledge to the contrary1 that twenty-eight years constituted a sufficiently long period for the enjoyment by ,mr4 ,wood1 of the full and exclusive right and liberty of making1 constructing1 using and vending to others to be used1 the plow which he had invented4 ,no doubt some members of ,congress in refusing to continue the patent for a third term1 acted from conscientious motives4 ,but in point of fact1 the period was occupied in a series of struggles calamitous to the inventor1 to the history of which we must now turn4 ,these struggles were unlike those in the lives of some other great inventors1 notably1 ,goodyear and ,howe4 ,it was not a warfare for existence1 the wolf of poverty staring him in the face4 ,the broad fields which he had inherited from his father were adequate immunity from the sad fate too frequently allotted to inventors4 ,but no benefactor of mankind in the domain of mechanism ever experienced more iniquitous treatment than ,jethro ,wood did4 ,before the year #ahai closed1 his mission as an inventor was an accomplished fact4 ,the popular name given his implement1 ,the ,cast ,iron ,plow1 from its entire abandonment of wrought iron in its construction1 needed no change to be the noblest gift ever made to agriculture4 ,in the ideal1 hope had ripened into full fruition4 ,and now1 at this day1 looking at the matter in the light of the past1 seeing the absolutely incalculable benefits of the invention1 it seems almost incredible that the ,american people1 then even more than now1 a nation of farmers1 should not have hailed the new plow as an unspeakable boon1 especially the community in which he dwelt1 for ,cayuga county then1 as now1 under a high state of cultivation1 was and is peopled by a population of much more than average intelligence4 ,but an inventor1 like a prophet1 is not without honor save in his own country4 ,his neighbors gravely shook their heads at ,jethro's folly4 ,with almost entire unanimity they agreed that the new contrivance would never work4 ,his trials and difficulties at this stage of progress are told as follows1 by one who wrote largely from personal recollection3 ,he immediately began to manufacture his plows1 and introduce them to the farmers in his neighborhood4 ,the difficulties which he now encountered would have daunted any man without extraordinary perseverance and a firm belief in the inestimable benefit to agriculture sure to result from his invention4 ,he was obliged to manufacture all the patterns1 and to have the plow cast under the disadvantages usual with new machinery4 ,the nearest furnace was thirty miles from his home1 and1 baffled by obstacles which unskillful and disobliging workmen threw in his way1 he visited it1 day after day1 directing the making of his patterns1 standing by the furnaces while the metal was melting1 and often with his own hands aiding in the casting4 ,when1 at length1 samples of his plow were ready for use1 he met with another difficulty in the unwillingness of the farmers to accept them4 ',what1' they cried1 in contempt1 'a plow made of pot metal8 ,you might as well attempt to turn up the earth with a glass plowshare4 ,it would hardly be more brittle4' ,one day he induced one of the most skeptical neighbors to make a public trial of the plow4 ,a large concourse gathered to see how it would work4 ,the field selected for the test was thickly strewn with stones1 many of them firmly imbedded in the soil1 and jutting up from the surface4 ,all predicted that the plow would break at the outset4 ,to their astonishment and ,wood's satisfaction1 it went around the field1 running easily and smoothly1 and turning up the most perfect furrow which had ever been seen4 ,the small stones against which the farmer maliciously guided it1 to test the 'brittle' metal1 moved out of the way as if they were grains of sand1 and it slid around the immovable rocks as if they were icebergs4 ,incensed at the non-fulfillment of his prophecy1 the farmer finally drove the plow with all force upon a large bowlder1 and found to his amazement that it was uninjured by the collision4 ,it proved a day of triumph for ,jethro ,wood1 and from that time he heard few taunts about the pot-metal4 ,it was soon discovered that his plow turned up the soil with so much ease that two horses could do the work for which a yoke of oxen and a span of horses had sometimes been insufficient before2 that it made a better furrow1 and that it could be bought for seven or eight dollars2 no more running to the blacksmith1 either1 to have it sharpened4 ,it was proved a thorough and valuable success4 ,thomas ,jefferson1 from his retirement at ,monticello1 wrote ,wood a letter of congratulation1 and although his theory of the construction of mould-boards had differed entirely from the inventor's1 gave his most hearty appreciation to the merits of the new plow4 ,in this connection may be told a curious episode1 one in itself worthy of record1 and strikingly illustrative of the perversities of fortune to ,mr4 ,wood in those gloomy days4 ,it is the story of a ,czar and a ,citizen4 ,all uncertainty as to the feasibility of the new plow having been removed1 and actuated by that broad philanthropy which was one of the peculiar charms in the character of ,mr4 ,wood1 he desired to extend as widely as possible the area of his usefulness1 and concluded to make the ,czar of ,russia1 so long the chief grain exporting country of the world1 the present of one of his plows4 ,during the ,revolutionary war1 then fresh in the ,american mind1 that great sovereign1 ,catherine of ,russia1 had been the staunch friend of this country1 and that1 too1 without being impelled by jealousy of ,great ,britain4 ,it seems to be a peculiar trait in the ,romanoff family to admire liberty in the abstract1 however absolute in practice4 ,sharing the prevailing good will toward ,russia1 ,mr4 ,wood conceived this happy thought of making a truly substantial contribution to ,cossack civilization1 a civilization ever ready1 with all its crudeness1 to adopt foreign improvements4 ,that gift1 in one point of view slight1 proved of great benefit to ,russian agriculture4 ,it is impossible to state the extent of actual advantage derived by ,russia from that truly imperial gift4 ,it was in effect giving to that country1 second only to the ,united ,states in area of tillage1 in proportion to population1 the free use of the perfected plow4 ,in an old copy of the ,new ,york ,tribune1 in its palmy days of ,horace ,greeley and ,solon ,robinson1 the tale of the ,plow and the ,ring is unfolded4 ,it runs thus3 ,during the year1 #ahbj1 ,jethro ,wood sent one of his plows to ,alexander ,i1 ,emperor of ,russia1 and the peculiar circumstances attending the gift and its reception formed a large part of the newspaper gossip of the day4 ,wood1 though a man of cultivation1 intellectually as well as agriculturally1 was not familiar with ,french1 which was then as now the diplomatic language4 ,so he requested his personal friend1 ,dr4 ,samuel ,mitchill1 ,president of the ,new ,york ,society of ,natural ,history and ,sciences1 to write a letter in ,french to accompany the gift4 ,the autocrat of all the ,russias received the plow and the letter1 and sent back a diamond ring--which the newspapers declared to be worth from #g1jjj to #ae1jjj--;in token of his appreciation4 ,by some indirection1 the ring was not delivered to the donor of the plow1 but to the writer of the letter1 and ,dr4 ,mitchill instantly appropriated it to his own use4 ,wood appealed to the ,russian ,minister at ,washington for redress4 ,the ,minister sent to ,his ,emperor and asked to whom the ring belonged1 and ,alexander replied that it was intended for the inventor of the plow4 ,armed with this authority1 ,wood again demanded the ring of ,mitchill4 ,but there were no steamships or telegraphs in those days1 and ,mitchill declared that in the long interval in which they had been waiting to hear from ,russia1 he had given it to the cause of the ,greeks1 who were then rising to throw off the yoke of their ,turkish oppressors4 ,a newspaper of the time calls ,mitchill's course 'an ingenious mode of quartering on the enemy1' and the inventor's friends seem to have believed that the ring had been privately sold for his benefit4 ,at all events it never came to light again1 and ,wood1 a peaceful man1 a ,quaker by profession1 did not push the matter further4 ,perhaps another and quite as potent a reason why ,friend ,wood did not follow up this matter was that weightier affairs demanded his immediate and entire attention4 ,one difficulty was overcome only to develop another4 ,no sooner had he silenced the cavils of the farmers and demonstrated the value of his patent1 than infringements upon his rights threatened to1 and actually did1 rob him of the fruits of his invention4 ,uneasy rests the head that wears a crown of genius4 ,the patent laws of that day were very imperfect1 and there was a strong prejudice against their enforcement4 ,the cry of no monopoly was raised4 ,mr4 ,wood had expended many thousands of dollars in perfecting his patterns and getting ready to supply the demand which he felt sure would arise for his plows1 many of which1 during the first few years1 he gave away1 that their value might be established to the satisfaction of the public4 ,the stage of probation over1 the plow makers of the country1 defiant of patent law1 engaged in their manufacture4 ,his patent had fourteen years to run4 ,in an incredibly short time their use by the farmers in all parts of the land became almost universal1 and had he been allowed a royalty1 however small1 he would have realized a vast fortune4 ,instead of that he very nearly exhausted all his property in unavailing endeavors to establish through the courts his rights as inventor and patentee4 ,in #ahcc1 when his patent expired1 ,congress granted a renewal for fourteen years4 ,he was now bowed with the burden of years1 and debts incurred in trying to protect himself against infringers4 ,his remaining days were spent in vain efforts to maintain his rights4 ,his broad and kindly nature had conceived noble plans for the use of the wealth which at one time seemed so nearly within his reach4 ,he had always been deeply interested in education1 and had fortune smiled upon him it is not too much to say that in spirit1 however different in detail1 ,jethro ,wood would have anticipated ,stephen ,girard1 ,ezra ,cornell and ,john ,s4 ,hopkins1 in nobly founding a great institution of learning4 ,in private life ,jethro ,wood was a model man4 ,if he had faults it is impossible to ascertain them1 for it would seem1 from the concurrent testimony of all who were acquainted with him1 that ,none knew him but to love him1 ,none name him but to praise4 ,although a consistent member of the ,society of ,friends1 ,mr4 ,wood was extremely liberal in his religious views1 and did not conform to the peculiar dress of the sect4 ,he had that truly ,catholic spirit so admirably characteristic of the great ,quaker-poet1 ,john ,g4 ,whittier4 ,not even the cruel wrongs he sustained at the hands of dishonest infringers could turn the sweetness of his kindly temper4 ,nature had endowed him richly in every way1 and no gift had been abused4 ,physically1 his was the highest type of manly beauty4 ,six feet and two inches in height1 perfect in proportion1 courtly in manner1 his presence was worthy his character4 ,we will not linger over the closing scene of his eventful life4 ,that belongs to the sacred secrecy of private grief4 ,his death occurred at the very threshold of a new conflict1 and upon it his son and executor1 ,benjamin ,wood1 entered with intelligent zeal4 ,the closing of it being reserved for two of his daughters4 ,the story of these new labors was well told several years ago by a journalist familiar with the facts1 and we cannot do better than to unearth the record from its musty file1 and by transcribing it to these pages1 give it a kind of resurrection worthy its importance4 ,after the death of ,jethro ,wood1 his son ,benjamin1 who received the invention as a legacy1 continued his efforts to wrest justice from the unwilling hand of the law4 ,nearly all his father's failures had proceeded from the inadequacy of the patent laws1 which were almost worthless to protect the rights of the inventor4 ,even now a patent is worth little until it has been fought through the ,supreme ,court of the ,united ,states4 ,in those days so many obstacles were thrown in the way of inventors1 and the combinations against them were so formidable1 that ,eli ,whitney1 in trying to establish his right to the cotton-gin in a ,georgia court1 while his machine was doubling and trebling the value of lands through the ,state1 had this experience1 which is given in his own words3 ,i had great difficulty in proving that the machine had been used in ,georgia1 although at the same moment there were three separate sets of this machinery in motion within fifty yards of the building in which the court sat1 and all so near that the rattling of the wheels was distinctly heard on the steps of the ,court ,house4 ,similar difficulties had met ,jethro ,wood in his suits2 so his son resolved to strike at the root of the evil by securing a reform in the laws4 ,he accordingly went to ,washington1 where he remained through several sessions1 always working to this end4 ,clay1 ,webster1 and ,john ,quincy ,adams1 all of whom had known ,jethro ,wood and his invention1 aided his son powerfully with their votes and counsel1 and he succeeded in securing several important changes in the patent laws4 ,then he returned to ,new ,york1 and commenced suit to resist encroachments on his right1 and the wholesale manufacture of his plow by those who refused to pay the premium to the inventor4 ,the ',cast-,iron ,plow' was now used all over the country1 and formidable combinations of its manufacturers united their capital and influence against ,benjamin ,wood4 ,william ,h4 ,seward1 then practicing law1 was retained as ,wood's counsel1 and the plow-makers engaged all the talent they could muster to oppose him4 ,heretofore it had never been contradicted that ,jethro ,wood was the originator of the plow in use1 but now his right to the invention was denied1 and it was alleged that his improvements had been forestalled by other makers4 ,again and again the case was adjourned1 and ,europe and ,america were ransacked for specimens of the different plows which were declared to include his patent4 ,mr4 ,wood also obtained from ,england samples of the plows of ,james ,small and ,robert ,ransom4 ,he searched ,new-,jersey to find the ,peacock plow which was said to have a cast-iron mould-board of exactly similar shape to his father's4 ,everywhere in that ,state he found ',wood's plow' in use1 but he could hear nothing of the one he sought4 ,at length riding near a farm-house he discovered one of the old ',newbold-,peacock plows' lying under a fence1 dilapidated and rust-eaten4 ',we don't use it any more1' the farmer replied to his inquiries1 'we've got one a good deal better4' ',will you sell this8' asked ,wood4 ',well1 yes4' ,and ,wood1 glad to get it at almost any price1 paid the keen farmer1 who took advantage of his evident anxiety1 two or three times the price of a new plow1 and added the old one to his specimens4 ,this motley collection of implements was brought into court and exhibited to the judges4 ,at last1 after the case had dragged its slow length along1 through many terms1 and the plaintiff was nearly worn out with the law's delay1 the time for final trial and decision arrived4 ,the combination of plow-makers feared that the case would go in ,wood's favor1 and made every effort to keep him out of court1 that he might lose it by default4 ,during his long entanglement in the law1 he had contracted many debts1 and one of his opponents had managed to purchase several of these accounts4 ,just before the case was to be heard for the last time1 this worthy plow manufacturer1 attended by a sheriff1 and armed with a warrant to arrest ,wood for debt1 appeared at the front door of his house4 ,fortunately ,wood had had a few minutes warning1 and slipping out at the back door1 he made his way under cover of approaching darkness to a house of a friendly neighbor4 ,there he procured a horse and started for ,albany1 #aej miles distant1 hearing every moment in fancy the clattering of hoofs at his heels4 ,as if fortune could not be sufficiently ill-natured1 his horse proved vicious and unmanageable1 and thrice in the tedious journey threw the rider from his saddle upon the frozen earth1 so injuring him1 that he was barely able to go on4 ,on arriving at ,albany he found himself not a moment too soon4 ,the case had an immediate hearing1 and after three days' trial the ,circuit ,court decided unequivocally that the plow now in general use over the country was unlike any other which had been produced2 that the improvements which rendered it so effective were due to ,jethro ,wood1 and that all manufacturers must pay his heirs for the privilege of making it4 ,this was a great triumph2 but it was now the late autumn of #ahde1 and the last grant of the patent had little more than a year to run4 ,wood again repaired to ,washington to apply for a new extension1 but the excitements of so long a contest had been too much for him4 ,just as he had recommenced his efforts they were forever ended4 ,while talking with one of his friends1 he suddenly fell dead from heart disease1 and the patent expired without renewal4 ,the last male heir to the invention was no more4 ,on settling the estate1 it was found that while not a vestige remained of the large fortune owned by ,jethro ,wood when he began his career1 less than five hundred and fifty dollars had ever been received from his invention4 ,the after history of the case is a brief one4 ,four daughters of ,jethro ,wood alone remained to represent the family4 ,in the winter of #ahdh the two younger sisters went to ,washington to petition ,congress that a bill might be passed for their relief1 in view of the inestimable services of their father to the agricultural interests of the country4 ,webster declared that he regarded their father as a 'public benefactor1' and gave them his most efficient aid2 ,clay warmly espoused their cause1 and the venerable ,john ,quincy ,adams1 with his trembling hand--then so enfeebled by age that he rarely used the pen--wrote them kind notes1 heartily sympathizing with them4 ,on one memorable day1 while they were in the ,house gallery1 ,mr4 ,adams1 at his desk on the floor1 wrote them briefly in relation to their case4 ,a few minutes later he was struck with the fatal attack under which he exclaimed1 ',this is the last of earth2 ,i am content1' and was borne dying to the ,speaker's room4 ,the tremulous lines1 the last his hand ever traced1 were found on his desk and delivered to ,miss ,wood4 ,a bill providing that in these four heirs should rest for seven years the exclusive right of making and vending the improvements in the construction of the cast-iron plow2 and that twenty-five cents on each plow might be exacted from all who manufactured it1 passed the ,senate unanimously4 ,but ,washington already swarmed with plow manufacturers4 ,the city of ,pittsburgh alone sent five to look after their interests4 ,money was freely used1 and the members of the ,house ,committee who were to report on the bill were assured that during the #bh years of the patent1 ,wood's family had reaped immense wealth1 and wished to keep up a monopoly4 ,the two quiet ladies1 fresh from the retirement of a ,quaker home1 where they had learned little of the world1 were even accused of attempting to secure its extention through bribery4 ,it was the wolf charging the lamb with roiling the water4 ,so ignorant were they of such means1 that1 though the ,chairman of the ,committee plainly told the younger lady in a few words of private conversation that a very few thousand dollars would give her a favorable verdict1 she did not understand the suggestion till after an unfavorable report was presented1 and the bill killed in the ,house4 ,when they were about to leave ,washington1 some friendly members of ,congress advised them to deposit the valuable documents which had been used in their suit1 including the letter from ,thomas ,jefferson to ,jethro ,wood1 in the archives of the ,house1 where they could only be withdrawn on the motion of some member4 ,they did so1 and left them for some years uncalled for4 ,when at last they applied for them they could not be found4 ,nor from that time to the present has any trace of them been discovered by any of the family4 ,thus perished the last vestige of proof relating to this ill-fated invention4 ,this is a fair and candid statement1 one fully sustained by unimpeachable documentary evidence4 ,especially by the somewhat voluminous pamphlet entitled ,documents relating to the improvements of ,jethro ,wood in the ,construction of the ,plough4 ,a careful examination of the testimony therein embodied1 and of the ,congressional ,reports on the subject1 warrant the foregoing statements4 ,it is not strange that in an early annual report of the ,united ,states ,commissioner of ,agriculture1 that official should have remarked with some bitterness that ,although ,wood was one of the greatest benefactors to mankind by this admirable invention1 he never received1 for all his thought1 anxiety and expense1 a sum of money sufficient to defray the expenses of his decent burial4 ,the time long since passed forever to seek pecuniary indemnity2 but a debt of gratitude never outlaws1 and it is due to the great inventor that his countrymen should gratefully cherish his memory4 ,every year adds to the debt we all owe him4 ,as the area of cultivation widens1 the obligation deepens4 ,already ,america is the foremost nation of all the earth in the production of wheat and provisions1 the latter being in reality corn in meat form4 ,in exchange for our food supplies1 the ,united ,states is draining ,europe of its gold at an enormous rate1 and the fundamental element in the production of ,american wealth1 is our great implement of tillage4 ,american prosperity is the monumental glory of ,jethro ,wood and his plow4 ,the ,balance ,sheet of the ,world shows that the ,united ,states can boast more acres of tillage1 in proportion to population1 than any other country on the globe2 and in grain production1 outstrips all competitors4 ,of such a record every ,american citizen may well be proud1 and it should be remembered that without the genius of ,wood such a record could not have been made1 even approximately4 ,but in order to a just appreciation of the importance of the modern plow and the usefulness of the inventor of it1 one should take a retrospective glance1 tracing1 as best we may without tedious details1 the steps which led from the use of a forked stick to the present implement for fallowing the ground4 ,the ,scientific ,american1 which ought to be good authority on such a subject1 in speaking of the ,wood patent1 says3 ,previously the plow was a stick of wood plated with iron4 ,if this does sound like an exaggeration1 but is really a plain statement of fact1 consider for a moment what the plow really is in its relation to civilization4 ,the savage lives by the chase and upon the bounty of untilled nature4 ,the first steps toward civilization are to domesticate animals1 and cultivate the soil with a rude kind of hoe4 ,both are alike primitive4 ,the next step is to press the beast into service by supplementing the hoe with a plow4 ,in that implement we see what might be called the original strand in the mighty cord which binds in co-operation man1 brute and earth4 ,by means of this agency of agriculture the beast of the field is made to toil1 and purchases the benefits of human kindness at the expense of idleness and industry4 ,it is not too much1 then1 to say that the plow is at once the tie that binds1 and the tap-root which nourishes the world4 ,if by some miraculous calamity this one implement were forever swept away1 universal and unappeasable famine would be inevitable4 ,and that occasional famines of a local character are disappearing from the civilized world1 is very largely1 if not chiefly1 due to the improved tillage resulting from improved plows4 ,we might well say1 in paraphrase of a familiar saying attributed to ,napoleon3 ,let me make the plows of a nation1 and ,i care not who makes their laws4 ,the primitive plow was and is 7for the barbarian of to-day is substantially the same in his agricultural methods as the barbarian of antiquity7 simply a forked stick1 to which is attached by a strip of rawhide or a wisp of grass1 a beast1 often the patient cow4 ,as the prong passes over the ground1 held down by the bowed form of the poor tiller1 it barely scratches the face of the earth4 ,the first improvement was to reverse the stick and notch the forward end4 ,by that means the animal could be more securely fastened to the plow1 the thong being tied around the crotch of the stick4 ,the shorter limb ran along the surface of the ground1 the notch in front being the only reliance for stirring the soil4 ,in the absence of a compact turf1 such plowing would do a little good in rendering the ground fallow1 and would at least have the merit of not being so difficult to operate as its predecessor4 ,the third plow had three parts4 ,it consisted of a beam1 a handle and a share1 all constructed by simply trimming the natural wood selected for that purpose4 ,in the first plow the prong which served as a share was slanting1 while in the third it rested flatly upon the ground1 projecting forward1 instead of backward1 as in the second plow4 ,it could have required no very difficult search to have found small trees and broken limbs1 needing no mechanical skill in fashioning1 to render them serviceable for such crude uses4 ,they may be termed nature's contribution to the art of plow-making4 ,without going further into details1 it may be stated that a standard authority on the history of mechanism asserts that the ancient ,egyptian1 ,etruscan1 ,syrian1 and ,greek plows1 were equal to the modern plows of the south of ,france1 part of ,austria1 ,poland1 ,sweden1 ,spain1 ,turkey1 ,persia1 ,arabia1 ,india1 ,ceylon and ,china2 at least such was the case until the middle of the present century4 ,the ,roman and ,gallic plows were better than those of the modern countries named4 ,the ,gauls had mould-board plows4 ,pliny is our authority for this statement4 ,that eminent ,latin author of eighteen centuries ago1 in speaking on the general subject1 says3 ,plows are of various kinds4 ,the colter is the iron part which cuts the thick sod before it is broken into pieces and traces beforehand by its incision the future furrows1 which the share1 reversed1 is to open with its teeth4 ,another kind1 the common plowshare1 is nothing more than a lever furnished with a pointed beak2 while another variety1 which is used in light1 easy soils1 does not present an edge projecting from the share-beam throughout1 but only a small point at the extremity4 ,in a fourth kind1 again1 this point is larger and formed with a cutting edge by the agency of which it cleaves the ground1 and by the sharp edges at the side cuts up the weeds by the roots4 ,pliny adds that the broader the plowshare the better it is for turning up the soil4 ,these excerpts from the great ,roman may serve to show the utmost reach of invention in that line1 until a new impulse1 begun in the ,netherlands in the eighteenth century1 was brought to perfect development in the next century by an ,american citizen who died the poorer for his invention4 ,the highest of all authorities upon this and cognate subjects is ,knight's ,american ,mechanical ,dictionary1 and ,knight says of ,jethro ,wood1 ,he made the best plows up to date4 ,he adds1 ,he met with great opposition1 and then with much injustice1 losing a competency in introducing his plow and fighting infringers4 ,the same writer defines the peculiarities of the ,wood plow with remarkable clearness and brevity3 ,it consisted in the mode of securing the cast-iron portions together by lugs and locking pieces1 doing away with screw-bolts1 and much weight1 complexity and expense4 ,it was the first plow in which the parts most exposed to wear could be renewed in the field by the substitution of cast pieces4 ,considering the source of this passage1 it may be said that literature could hardly pay a nobler tribute to the memory of ,jethro ,wood than this4 ,it is doubly significant1 from the fact that ,knight's publishers1 ,houghton1 ,osgood ,co41 are also the publishers of the ,atlantic ,monthly1 in the ,may number of which magazine a habitue of the ,national ,capital tried to belittle the invention of ,jethro ,wood1 and malign as iniquitous the attempt of his daughters1 championed by ,john ,quincy ,adams1 to secure for that invention proper recognition4 ,it would be quite superfluous to follow this maligner in the details of this1 and a subsequent attack in an agricultural journal4 ,he disclaims any design to defame the claimants1 but insists that other and earlier inventors deserve the credit for the modern plow4 ,the opinion of ,knight's ,dictionary upon the ,wood patent has just been given1 and the following extract from the same great work sets forth in their proper relations to the modern plow the inventions of those for whom this habitue makes preposterous claims3 ,the modern plow1 says ,knight1 originated in the low countries1 so-called4 ,flanders and ,holland gave to ,england much of her husbandry and gardening knowledge1 field1 kitchen and ornamental4 ,blythe's ',improver ,improved1' published in #afeb1 has allusions to the subject4 ,lummis1 in #agbj1 imported plows from ,holland4 ,james ,small1 of ,berwickshire1 ,scotland1 made plows and wrote treatises on the subject1 #aghd4 ,he made cast-iron mold-boards and wrought-iron shares1 and introduced the draft-chain4 ,he made shares of cast-iron in #aghe4 ,the importation of what was known as the ',rotherham' plow was the immediate cause of the improvement in plows which dates from the middle of the last century4 ,whether the name is derived from ,rotterdam cannot be determined4 ,the ,american plow1 during the colonial period1 was of wood1 the mold-board being covered with sheet-iron1 or plates made by hammering out old horseshoes4 ,jefferson studied and wrote on the subject1 to determine the proper shape of the mold-board4 ,he treated it as consisting of a lifting and an upsetting wedge1 with an easy connecting curve4 ,newbold1 of ,new ,jersey1 in #agig1 patented a plow with a mold-board1 share and land side all cast together4 ,peacock1 in his patent of #ahjg1 cast his plow in three pieces1 the point of the colter entering a notch in the breast of the share4 ,it will be observed that the credit given these improvers of the plow is very considerable1 without at all trenching upon the exceptional credit due to ,jethro ,wood4 ,with such an authoritative refutation1 the slander may well be dismissed as beneath further notice4 ,in no way more appropriately can final leave be taken of the subject in hand than by presenting the apostrophe to ,jethro ,wood from the pen of ,edward ,webster1 formerly associated editor of the ,rural ,new ,yorker3 ,no jeweled diadem or crown ,e'er glittered on thy manly brow-- ,no slave would tremble at thy frown1 ,nor at thy footstool bow2 ,for thou wert pure in heart and mind1 ,and strove to raise--not crush mankind6 ,as famed ,prometheus of yore1 ,in aid of our lost1 wretched sires1 ,stole from the flaming-sun1 and bore ,down to the earth those fires ,that fill with light and life all space1 ,and mark the ,day ,god's glorious race-- ,so thy inventive genius found ,for man the bright and polished share1 ,that bids the willing fields abound ,with fruits beyond compare2 ,and from the seed that falls like rain ,crowds full our barns with bearded grain6 ,eternal may the honors shine1 ,we yield with grateful hearts to thee2 ,may children's children round thy shrine-- ,sons of the brave and free-- ,with reverent lips pronounce thy name1 ,and build for thee a deathless fame6
