The Age of Invention [32]
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
