The very latest is a machine called the supplement press, capable of
printing complete a paper of from eight to twelve pages, depending on
the demand of the day, so that the papers slide out of the machine with
the supplements gummed in and the paper folded ready for delivery. Of
late years many other remarkably ingenious presses of other makers have
come into the market, but still the genius of R. M. Hoe has left an
indelible mark in the development of the printing-press. He died June
6th, 1886.

CHARLES GOODYEAR.

About the year 1800 was born in New Haven, Connecticut, Charles
Goodyear. He received only a public school education, and when
twenty-one years of age joined his father in the hardware trade in the
city of Philadelphia; but in the financial troubles of 1830, the firm
went under, and the next three years was spent in looking for a
life-work.

Passing a store in the city of New York, his eye was attracted by the
words "INDIA RUBBER FOR SALE." Having heard much of this new article of
late, he purchased a life-preserver which he carried home and so
materially improved, in conception, that he was induced to return to the
store for the purpose of explaining his ideas. At the store he was now
told of the great discouragements with which the rubber trade was
contending, the merchants giving this as a reason for not taking to his
improvement. The rubber, as then made, would become as hard as flint
during cold weather, and if exposed to heat would melt and decay.

Returning to Philadelphia, Goodyear commenced experiments, trying to
discover the secret of how to remedy this trouble. He was very poor, and
to support his family he 'cobbled' for his neighbors. He tried every
experiment within his grasp of intellect, but met only with failure. His
friends, who had helped him, left him one by one; his failures
continued, but he would not give up. The last piece of furniture was
sold, and his family moved into the country, taking up cheap lodgings.
Finally he found a druggist who agreed to furnish him what he needed
from his store to use in his investigations and purchasing small
quantities of rubber at a time he continued his experiments. At length,
after three years he discovered that the adhesiveness of the rubber
could be obviated by dipping it in a preparation of nitric acid. But
this only affected the exterior, and he was once m
