India-rubber had been known for more than a hundred years when Charles Goodyear undertook to make of it thousands of articles useful in common life. So long ago as 1735 a party of French astronomers discovered in Peru a curious tree that yielded the natives a peculiar gum or sap which they collected in clay vessels. This sap became hard when exposed to the sun, and was used by the natives, who made different articles of every-day use from it by dipping a clay mould again and again into the liquid. When the article was completed the clay mould was broken to pieces and shaken out. In this manner they made a kind of rough shoe and an equally rough bottle. In some parts of South America the natives presented their guests with these bottles, which served as syringes for squirting water. Articles thus made were liable to become stiff and unmanageable in cold weather and soft and sticky in warm. Upon getting back to France the travellers directed the attention of scientists to this remarkable gum, which was afterward found in various parts of South America, and the chief supplies of which still come from Brazil. About the beginning of the present century this substance, known variously as cachuchu, caoutchouc, gum-elastic, and india-rubber, was first commercially introduced into Europe. It was regarded merely as a curiosity, chiefly useful for erasing pencil-marks. Ships from South America took it over as ballast. About the year 1820 it began to be used in France in the manufacture of suspenders and garters, india-rubber threads being mixed with the material used in weaving those articles. Some years later Mackintosh, an English manufacturer, used it in his famous water-proof coats, which were made by spreading a layer of the gum between two pieces of cloth.
About the same time a pair of india-rubber shoes were exhibited in Boston, where they were regarded as a curiosity; they were covered with gilt-foil to hide their natural ugliness. In 1823 a Boston merchant, engaged in the South American trade, imported five hundred pairs of these shoes, made by the natives of Para, and found no difficulty in selling them. In fact, this became a large business, although these shoes were terribly rough and clumsy and were not to be depended upon; in cold weather they became so hard that they could be used only after being thawed by the fire, and in summer they could be preserved only by keeping them on ice. If during the thawing process they were placed too near the fire, they would melt into a shapeless mass; and yet they cost from three to five dollars a pair.
In 1830 E.M. Chaffee, of Boston, the foreman of a patent leather factory in that city, attempted to replace patent leather by a compound of india-rubber. He dissolved a pound of the gum in spirits of turpentine, added to the mixture enough lamp-black to produce a bright black color, and invented a machine for spreading this compound over cloth. When dried in the sun it produced a hard, smooth surface, flexible enough to be twisted into any shape without cracking. With the aid of a few capitalists, Chaffee organized, in 1833, a company called the Roxbury India-rubber Company, and manufactured an india-rubber cloth from which wagon-covers, piano-covers, caps, coats, shoes, and other articles were made. The product of the factory sold well, and the success of the Roxbury Company led to the establishment of a number of similar factories elsewhere. Apparently all who were engaged in the production of rubber goods were on the highway to wealth.
