iercely among themselves。 At the suggestion of George Gifford; a New York attorney; the leading inventors and manufacturers agreed to pool their inventions and to establish a fixed license fee for the use of each。 This 〃combination〃 was composed of Elias Howe; Wheeler and Wilson; Grover and Baker; and I。 M。 Singer; and dominated the field until after 1877; when the majority of the basic patents expired。 The members manufactured sewing machines and sold them in America and Europe。 Singer introduced the installment plan of sale; to bring the machine within reach of the poor; and the sewing machine agent; with a machine or two on his wagon; drove through every small town and country district; demonstrating and selling。 Meanwhile the price of the machines steadily fell; until it seemed that Singer's slogan; 〃A machine in every home!〃 was in a fair way to be realized; had not another development of the sewing machine intervened。

This was the development of the ready…made clothing industry。 In the earlier days of the nation; though nearly all the clothing was of domestic manufacture; there were tailors and seamstresses in all the towns and many of the villages; who made clothing to order。 Sailors coming ashore sometimes needed clothes at once; and apparently a merchant of New Bedford was the first to keep a stock on hand。 About 1831; George Opdyke; later Mayor of New York; began the manufacture of clothing on Hudson Street; which he sold largely through a store in New Orleans。 Other firms began to reach out for this Southern trade; and it became important。 Southern planters bought clothes not only for their slaves but for their families。 The development of California furnished another large market。 A shirt factory was established; in 1832; on Cherry and Market Streets; New York。 But not until the coming of the power…driven sewing machine could there be any factory production of clothes on a large scale。 Since then the clothing industry has become one of the most important in the country。 The factories have steadily improved their models and materials; and at the present day only a negligible fraction of the people of the United States wear clothes made to their order。

The sewing machine today does many things besides sewing a seam。 There are attachments which make buttonholes; darn; embroider; make ruffles or hems; and dozens of other things。 There are special machines for every trade; some of which deal successfully with refractory materials。

The Singer machine of 1851 was strong enough to sew leather and was almost at once adopted by the shoemakers。 These craftsmen flourished chiefly in Massachusetts; and they had traditions reaching back at least to Philip Kertland; who came to Lynn in 1636 and taught many apprentices。 Even in the early days before machinery; division of labor was the rule in the shops of Massachusetts。 One workman cut the leather; often tanned on the premises; another sewed the uppers together; while another sewed on the soles。 Wooden pegs were invented in 1811 and came into common use about 1815 for the cheaper grades of shoes: Soon the practice of sending out the uppers to be done by women in their own homes became common。 These women were wretchedly paid; and when the sewing machine came to do the work better than it could be done by hand; the practice of 〃putting out〃 work gradually declined。

That variation of the sewing machine which was to do the more difficult work of sewing the sole to the upper was the invention of a mere boy; Lyman R。 Blake。 The first model; completed in 1858; was imperfect; but Blake was able to interest Gordon McKay; of Boston; and three years of patient experimentation and large expenditure followed。 The McKay sole…sewing machine; which they produced; came into use; and for twenty…one years was used almost universally both in the United States and Great Britain。 But this; like all the other useful inventions; was in time enlarged and greatly improved; and hundreds of other inventions have been made in the shoe industry。 There are machines to split leather; to make the thickness absolutely uniform; to sew the uppers; to insert eyelets; to cut out heel tops; and many more。 In fact; division of labor has been carried farther in the making of shoes than in most industries; for there are said to be about three hundred separate operations in making a pair of shoes。

From small beginnings great industries have grown。 It is a far cry from the slow; clumsy machine of Elias Howe; less than three…quarters of a century ago; to the great factories of today; filled with special models; run at terrific speed by electric current; and performing tasks which would seem to require more than human intelligence and skill。



CHAPTER V。 THE AGRICULTURAL REVOLUTION

The Census of 1920 shows that hardly thirty per cent of the people are today engaged in agriculture; the basic industry of the United States; as compared with perhaps ninety per cent when the nation began。 Yet American farmers; though constantly diminishing in proportion to the whole population; have always been; and still are; able to feed themselves and all their fellow Americans and a large part of the outside world as well。 They bring forth also not merely foodstuffs; but vast quantities of raw material for manufacture; such as cotton; wool; and hides。 This immense productivity is due to the use of farm machinery on a scale seen nowhere else in the world。 There is still; and always will be; a good deal of hard labor on the farm。 But invention has reduced the labor and has made possible the carrying on of this vast industry by a relatively small number of hands。

The farmers of Washington's day had no better tools than had the farmers of Julius Caesar's day; in fact; the Roman ploughs were probably superior to those in general use in America eighteen centuries later。 〃The machinery of production;〃 says Henry Adams; 〃showed no radical difference from that familiar in ages long past。 The Saxon farmer of the eighth century enjoyed most of the comforts known to Saxon farmers of the eighteenth。〃* One type of plough in the United States was little more than a crooked stick with an iron point attached; sometimes with rawhide; which simply scratched the ground。 Ploughs of this sort were in use in Illinois as late as 1812。 There were a few ploughs designed to turn a furrow; often simply heavy chunks of tough wood; rudely hewn into shape; with a wrought…iron point clumsily attached。 The moldboard was rough and the curves of no two were alike。 Country blacksmiths made ploughs only on order and few had patterns。 Such ploughs could turn a furrow in soft ground if the oxen were strong enoughbut the friction was so great that three men and four or six oxen were required to turn a furrow where the sod was tough。

Thomas Jefferson had worked out very elaborately the proper curves of the moldboard; and several models had been constructed for him。 He was; however; interested in too many things ever to follow any one to the end; and his work seems to have had little publicity。 The first real inventor of a practicable plough was Charles Newbold; of Burlington County; New Jersey; to whom a patent for a cast…iron plough was issued in June; 1797。 But the farmers would have none of it。 They said it 〃poisoned the soil〃 and fostered the growth of weeds。 One David Peacock received a patent in 1807; and two others later。 Newbold sued Peacock for infringement and recovered damages。 Pieces of Newbold's original plough are in the museum of the New York Agricultural Society at Albany。

Another inventor of ploughs was Jethro Wood; a blacksmith of Scipio; New York; who received two patents; one in 1814 and the other in 1819。 His plough was of cast iron; but in three parts; so that a broken part might be renewed without purchasing an entire plough。 This principle of standardization marked a great advance。 The farmers by this time were forgetting their former prejudices; and many ploughs were sold。 Though Wood's original patent was extended; infringements were frequent; and he is said to have spent his entire property in prosecuting them。

In clay soils these ploughs did not work well; as the more tenacious soil stuck to the iron moldboard instead of curling gracefully away。 In 1833; John Lane; a Chicago blacksmith; faced a wooden moldboard with an old steel saw。 It worked like magic; and other blacksmiths followed suit to such an extent that the demand for old saws became brisk。 Then came John Deere; a native of Vermont; who settled first in Grand Detour; and then in Moline; Illinois。 Deere made wooden ploughs faced with steel; like other blacksmiths; but was not satisfied with them and studied and experimented to find the best curves and angles for a plough to be used in the soils around him。 His ploughs were much in demand; and his need for steel led him to have larger and larger quantities produced for him; and the establishment which still bears his name grew to large proportions。

Another skilled blacksmith; William Parlin; at Canton; Illinois; began making ploughs about 1842; which he loaded upon a wagon and peddled through the country。 Later his establishment grew large。 Another John Lane; a son of
