Their prosperity was only fictitious, however, and a day of fearful disaster was pending over them. The bulk of the goods produced in 1833 and 1834 had been manufactured in the cold weather, and the greater part of them had succumbed to the heat of the ensuing summer. The shoes had melted to a soft mass, and the caps, wagon-covers, and coats had become sticky and useless in summer, and rigid in the cold of winter. In some cases the articles had borne the test of one year's use, but the second summer had ruined them. To make the matter worse, they emitted an odor so offensive that it was necessary to bury them in the ground to get rid of the smell. Twenty thousand dollars' worth were thrown back on the hands of the Roxbury Company alone, and the directors were appalled by the ruin which threatened them. It was useless for them to go on manufacturing goods which might prove worthless at any moment; and, as their capital was already taxed to its utmost, it was plain that unless a better process should be speedily discovered, they must become involved in irretrievable disaster. Their efforts were unavailing, however. No better process was found, and the disgust of the public with their goods was soon general and unmitigable. India-rubber stock fell rapidly, and by the end of the year 1836 there was not a solvent company in the Union. The loss of the stockholders was complete, and amounted in the aggregate to two millions of dollars. People came to detest the very name of India-rubber, since it reminded them only of blighted hopes and heavy losses. Before the final disaster, however, it chanced that a bankrupt merchant of Philadelphia, being one day in New York on business, was led by curiosity to visit the salesroom of the agency of the Roxbury Company in that city. His visit resulted in the purchase of a life-preserver, which he took home with him for the purpose of examining it. Subjecting it to a careful investigation, he discovered a defect in the valve used for inflating it, and promptly devised a simpler and better apparatus.
