foil to hide their natural ugliness. In 1823, a merchant, engaged in the South American trade, imported five hundred pairs from the Para district. He had no difficulty in disposing of them; and so great was the favor with which they were received, that in a few years the annual importation of India-rubber shoes amounted to five hundred thousand pairs. It had become a matter of fashion to wear these shoes, and no person's toilet was complete in wet weather unless the feet were incased in them; yet they were terribly rough and clumsy. They had scarcely any shape to them, and were not to be depended on in winter or summer. In the cold season they froze 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; and if, during the thawing process, they were placed too near the fire, there was danger that they would melt into a shapeless and useless mass. They cost from three to five dollars per pair, which was very high for an article so perishable in its nature.
The great popularity of India-rubber induced Mr. E.M. Chaflee, of Boston, the foreman of a patent leather factory in that city, to attempt to apply the new substance to some of the uses to which patent leather was then put. His hope was that, by spreading the liquid gum upon cloth, he could produce an article which, while possessing the durability and flexibility of patent leather, would also be water-proof. His experiments extended over a period of several months, during which time he kept his plan a secret. He dissolved a pound of the gum in three quarts of spirits of turpentine, and added to the mixture enough lamp-black to produce a bright black color, and was so well satisfied with his compound, that he felt sure that the only thing necessary to his entire success was a machine for spreading it properly on the cloth. Like a true son of New England, he soon overcame this difficulty by inventing the desired machine. His compound was spread on the cloth, and dried in the sun, producing a hard, smooth surface, and one sufficiently flexible to be twisted into any shape without cracking. Mr. Chaffee was now sure that he had mastered the difficulty. Taking a few capitalists into his confidence, he succeeded so
