The friend of the inventor was thoroughly disheartened by this failure, and refused to have any thing more to do with Goodyear's schemes; but the latter, though much disappointed, did not despair. He set to work to discover the cause of his failure, and traced it, as he supposed, to the mixing of the gum with the turpentine and lamp-black. Having procured some barrels of the gum in its native liquid state, he spread it on cloth without smoking it or mixing it with any thing else. He succeeded in producing a very handsome white rubber cloth, but it was one that became soft and sticky as quickly as the other had done. It now occurred to him that there must be some mineral substance which, mixed with the gum, would render it durable, and he began to experiment with almost every substance that he could lay his hands on. All these proved total failures, with the exception of magnesia. By mixing half a pound of magnesia with a pound of the gum, he produced a compound much whiter than the pure gum, and one which was at first as firm and flexible as leather. He made book-covers and piano-covers out of it, and for a time it seemed that he had discovered the longed-for secret; but in a month his pretty product was ruined. The heat caused it to soften; then fermentation set in, and, finally, it became as hard and brittle as thin glass. His friends, who had aided him at first, now turned from him coldly, regarding him as a dreamer; and his own stock of money was exhausted. In his extremity he was forced to pawn all his own valuables, and even some of the trinkets of his wife. In spite of this, he felt sure that he was on the road to success, and that he would very soon be enabled to rise above his present difficulties, and win both fame and fortune. He was obliged for the time, however, to remove his family to the country, depositing with his landlord, as security for the payment of the first quarter's rent, some linen which had been spun by his wife, and which he was never able to redeem. Having settled his family in the country, he set out for New York, where he hoped to find some one willing to aid him in extending his researches still further.
