The dentist was bending over a bench on which was a little copper in which he was vulcanizing some rubber, when he heard a voice calling, in a quick and imperative manner, these words: "Run to the window, quick! Run to the window, quick!"

We may judge, however, of the rapidity with which the business grew, by the fact that, six years after the completion of his vulcanizing process, the holders of rights to manufacture shoes by that process deemed it worth while to employ Daniel Webster to plead their cause, and to stimulate his mind by a fee of twenty-five thousand dollars.

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.

Out of the first piece of cloth which he succeeded in vulcanizing he had a coat made for himself, which was not an ornamental garment in its best estate; but, to prove to the unbelievers that it would stand fire, he brought it so often in contact with hot stoves, that at last it presented an exceedingly dingy appearance.

We need not revive those disputes which embittered his life and wasted his substance and his time. The Honorable Joseph Holt, the Commissioner who granted an extension to the vulcanizing patent in 1858, has sufficiently characterized them in one of the most eloquent papers ever issued from the Patent Office:

Macintosh of Glasgow, and Thomas Hancock of Newington, England, about 1820. From the dissolved caoutchouc, a coating was obtained making garments water-proof. In 1839 Charles Goodyear, an American, discovered the process of vulcanizing india-rubber, that is, producing in it a chemical change whereby its valuable qualities are greatly enhanced.

An attempt was made last winter to procure an act of Congress extending the vulcanizing patent for a further period of seven years, for the benefit of the creditors and the family of the inventor. The petition seemed reasonable.

On this process, which is by no means simple, the great rubber business of the world has been established. Practically everything made of rubber, or of which rubber is a part, has to go through the vulcanizing process, whether it is a pair of Keds, a tire, a fruit jar ring, or a doormat.

Then the seven wires stranded together in each end were unwound, carefully cleaned and scraped, that they might solder readily, after which they were again twisted together with pliers, and the joint completed. When this was done the rubber tape was wound round and round the copper wires, after which the whole was put into a vulcanizing bath of hot paraffine.

Probably he slept but little and was up early. At any rate he found the rubber unaffected by the cold. Then he knew that he had made a real discovery and he named the process "vulcanizing" after Vulcan, the Roman god of fire. "Vulcanizing" means mixing pure rubber with certain chemicals and then applying heat.
