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.
