Just before the failure of his mail-bags had brought ruin upon him, he had taken into his employ a man named Nathaniel Hayward, who had been the foreman of the old Roxbury works, and who was still in charge of them when Goodyear came to Roxbury, and was making a few rubber articles on his own account. He hardened his compound by mixing a little powdered sulphur with the gum, or by sprinkling sulphur over the rubber cloth and drying it in the sun. He declared that the process had been revealed to him in a dream, but could give no further account of it. Goodyear was astonished to find that the sulphur cured the india-rubber as thoroughly as the aqua fortis, the principal objection being that the sulphurous odor of the goods was frightful in hot weather. Hayward's process was really the same as that employed by Goodyear, the "curing" of the india-rubber being due in each case to the agency of the sulphur, the principal difference between them being that Hayward's goods were dried by the sun and Goodyear's with nitric acid. Hayward set so small a value upon his discovery that he readily sold it to his new employer. Goodyear felt that he had now all but conquered his difficulties. It was plain that sulphur was the great controller of india-rubber, for he had proved that when applied to thin cloth it would render it available for most purposes. The problem that now remained was how to mix sulphur and the gum in a mass, so that every part of the rubber should be subjected to the agency of the sulphur. He experimented for weeks and months with the most intense eagerness, but the mystery completely baffled him. His friends urged him to go to work to do something for his family, but he could not turn back. The goal was almost in sight, and he felt that he would be false to his mission were he to abandon his labors now. To the world he seemed a crack-brained dreamer, and some there were who, seeing the distress of his family, did not hesitate to apply still harsher names to him. Had it been merely wealth that he was working for, doubtless he would have turned back and sought some other means of obtaining it; but he sought more. He felt that he had a mission to fulfil, and that no one else could perform it.
