The discovery which followed was the result of accident, and brought him on the very threshold of success, yet did not entirely conquer his difficulties. He was an ardent lover of the beautiful, and it was a constant effort with him to render his productions as attractive to the eye as possible. Upon one occasion, while bronzing a piece of rubber cloth, he applied aqua fortis to it for the purpose of removing the bronze from a certain part. It took away the bronze as he had designed, but it also discolored the cloth to such a degree that he supposed it ruined, and threw it away. A day or two later, he chanced to remember that he had not examined very closely into the effect of the aqua fortis upon the rubber, and thereupon instituted a search for it. He was fortunate enough to find it, and was overjoyed to discover that the rubber had undergone a remarkable change, and that the effect of the acid was to harden it to such an extent that it would now stand a degree of heat which would have melted it before. When the reader remembers that aqua fortis is a compound two-fifths of which is sulphuric acid, he will understand that Mr. Goodyear had almost mastered the secret of vulcanizing rubber. He does not appear, however, to have known the true nature of aqua fortis, and called his process the "curing" of India-rubber by the use of that acid.
The "cured" India-rubber was subjected to many tests, and passed through them successfully, thus demonstrating its adaptability to many important uses. Mr. Goodyear readily obtained a patent for his process, and a partner with a large capital was found ready to aid him. He hired the old India-rubber works on Staten Island, and opened a salesroom in Broadway. He was thrown back for six weeks at this important time by an accident, which happened to him while experimenting with his fabrics, and which came near causing his death. Just as he was recovering and preparing to commence the manufacture of his goods on a large scale, the terrible commercial crisis of 1836 swept over the country, and, by destroying his partner's fortune at one blow, reduced Goodyear to absolute beggary. His family had joined him in New York, and he was entirely without the means of supporting them. As the only resource at hand, he decided to pawn an article of value, one of the few which he possessed, in order to raise money enough to procure one day's supply of provisions. At the very door of the pawnbroker's shop he met one of his creditors, who kindly asked if he could be of any further assistance to him. Weak with hunger, and overcome by the generosity of his friend, the poor man burst into tears, and replied that, as his family was on the point of starvation, a loan of fifteen dollars would greatly oblige him. The money was given him on the spot, and the necessity for visiting the pawnbroker averted for several days longer. Still he was a frequent visitor to that individual during the year; and thus, one by one, the relics of his better days disappeared. Another friend loaned him one hundred dollars, which enabled him to remove his family to Staten Island, in the neighborhood of the abandoned rubber works, which the owners gave him permission to use as far as he could. He contrived in this way to manufacture enough of his "cured" cloth, which sold readily, to enable him to keep his family from starvation. He made repeated efforts to induce capitalists to come to the factory and see his samples and the process by which they were made, but no one would venture near him. There had been money enough lost in such experiments, they said, and they were determined to risk no more.
Indeed, in all the broad land there was but one man who had the slightest hope of accomplishing any thing with India-rubber, and that one was Charles Goodyear. His friends regarded him as a monomaniac. He not only manufactured his cloth, but even dressed in clothes made of it, wearing it for the purpose of testing its durability, as well as of advertising it. He was certainly an odd figure, and in his appearance justified the remark of one of his friends, who, upon being asked how Mr. Goodyear could be recognized, replied: "If you see a man with an India-rubber coat on, India-rubber shoes, an India-rubber cap, and in his pocket an India-rubber purse, with not a cent in it, that is Goodyear."
In September, 1836, a new gleam of hope lit up his pathway. A friend having loaned him a small sum of money, he went to Roxbury, taking with him some of his best specimens. Although the Roxbury Company had gone down with such a fearful crash, Mr. Chaffee, the inventor of the process in this country, was still firm in his faith that India-rubber would at some future time justify the expectations of its earliest friends. He welcomed Mr. Goodyear cordially, and allowed him to use the abandoned works of the company for his experiments. The result was that Goodyear succeeded in making slides and cloths of India-rubber of a quality so much better than any that had yet been seen in America, that the hopes of the friends of India-rubber were raised to a high point. Offers to purchase rights for certain portions of the country came in rapidly, and by the sale of them Goodyear realized between four and five thousand dollars. He was now able to bring his family to Roxbury, and for the time fortune seemed to smile upon him.
His success was but temporary, however. He obtained an order from the General Government for one hundred and fifty India-rubber mail-bags, which he succeeded in producing, and as they came out smooth, highly polished, hard, well shaped, and entirely impervious to moisture, he was delighted, and summoned his friends to inspect and admire them. All who saw them pronounced them a perfect success; but, alas! in a single month they began to soften and ferment, and finally became useless. Poor Goodyear's hopes were dashed to the ground. It was found that the aqua fortis merely "cured" the surface of the material, and that only very thin cloth made in this way was durable. His other goods began to prove worthless, and his promising business came to a sudden and disastrous end. All his possessions were seized and sold for debt, and once more he was reduced to poverty. His position was even worse than before, for his family had increased in size, and his aged father also had become dependent upon him for support.
Friends, relatives, and even his wife, all demanded that he should abandon his empty dreams, and turn his attention to something that would yield a support to his family. Four years of constant failure, added to the unfortunate experience of those who had preceded him, ought to convince him, they said, that he was hoping against hope. Hitherto his conduct, they said, had been absurd, though they admitted that he was to some extent excused for it by his partial success; but to persist in it would now be criminal. The inventor was driven to despair, and being a man of tender feelings and ardently devoted to his family, might have yielded to them had he not felt that lie was nearer than ever to the discovery of the secret that had eluded him so long.
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, 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 on 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 sulphur, the principal difference between them being that Hayward's goods were dried by the sun, and Goodyear's with nitric acid. Hay ward set so small a value upon his discovery that he had 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; but to the Great Eye that reads all hearts, how different did this man appear! It saw the anguish that wrung the heart of Charles Goodyear, and knew the more than heroic firmness with which, in the midst of his poverty and suffering, he agonized for the great discovery. 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 was striving for the good of his fellow-men, and ambitious of becoming a benefactor of the race. He felt that he had a mission to fulfill, and no one else could perform it.
