The prize for which he had labored so long and so heroically was secured at last, and in 1844, ten years after the commencement of his experiments, he was able to produce perfectly vulcanized India-rubber with expedition and economy, and, above all, with certainty. He had won a success which added a new material to art and commerce, and one which could be applied in a thousand different ways, and all of them useful to man. But great as his success was, he was not satisfied with it. To the end of his life his constant effort was to improve his invention, and apply it to new uses. He had an unlimited faith in its adaptability, believing that there was scarcely any article of general use that could not be made of it. Upon one occasion he read in a newspaper that twenty persons perished every hour by drowning. The statement impressed him deeply, and his wife noticed that for several nights he scarcely slept at all. "Try to compose yourself, and sleep," she said to him.

And at this time it was his constant endeavor to invent some article of India-rubber which could be easily carried by travelers, and which would render it impossible for them to sink in water.
Having brought his process to a successful completion in this country, and obtained patents for it, he went to Europe to secure similar protections in
