To vulcanize India-rubber is about as difficult as to make perfect bread; but the art of bread-making was the growth of ages, and Charles Goodyear was only ten years and a half in perfecting his process. Thousands of ingenious men and women, aided by many happy accidents, must have contributed to the successive invention of bread; but he was only one man, poor and sick.
The safety-lamp had been given to the miner, the caisson to the bridge-builder, the anti-friction metal to the mechanic for bearings. It was already known how to vulcanize rubber, and how to galvanize iron. The application of machinery in the harvest-field had begun with the embryonic reaper, while both the bicycle and the automobile were heralded in primitive prototypes.
"Aw, yes," he said; "pickin' up a record or two, with my 'mobe; y' ought to see it; it's a beauty, gasolene, you know. Awful nuisance, punctures, though. Cost me thirteen dollars to repair one; vulcanize the tire, y'see. Tires weigh thirty pounds each; awful lot, ain't it? Stripped one right off, though, trying to turn in the mud; fastened on with half-inch spikes, too.
It cost him thousands of failures to learn that a little acid in his sulphur caused the blistering; that his compound must be heated almost immediately after being mixed, or it would never vulcanize; that a portion of white lead in the compound greatly facilitated the operation and improved the result; and when he had learned these facts, it still required costly and laborious experiments to devise the best methods of compounding his ingredients, the best proportions, the best mode of heating, the proper duration of the heating, and the various useful effects that could be produced by varying the proportions and the degree of heat.
The conditions upon which success depended were numerous, and the failure of one spoiled all....
