over the matter,
told him the check must be endorsed, and sent with him a young man to
identify him. The ceremony of identification performed with the paying
teller, who was quite merry over the incident, Edison was given the
amount in bundles of small bills "until there certainly seemed to be one
cubic foot." Unaware that he was the victim of a practical joke, Edison
proceeded gravely to stow away the money in his overcoat pockets and all
his other pockets. He then went to Newark and sat up all night with
the money for fear it might be stolen. Once more he sought help next
morning, when the General laughed heartily, and, telling the clerk that
the joke must not be carried any further, enabled him to deposit the
currency in the bank and open an account.

Thus in an inconceivably brief time had Edison passed from poverty to
independence; made a deep impression as to his originality and ability
on important people, and brought out valuable inventions; lifting
himself at one bound out of the ruck of mediocrity, and away from the
deadening drudgery of the key. Best of all he was enterprising, one of
the leaders and pioneers for whom the world is always looking; and, to
use his own criticism of himself, he had "too sanguine a temperament
to keep money in solitary confinement." With quiet self-possession he
seized his opportunity, began to buy machinery, rented a shop and got
work for it. Moving quickly into a larger shop, Nos. 10 and 12 Ward
Street, Newark, New Jersey, he secured large orders from General
Lefferts to build stock tickers, and employed fifty men. As business
increased he put on a night force, and was his own foreman on both
shifts. Half an hour of sleep three or four times in the twenty-four
hours was all he needed in those days, when one invention succeeded
another with dazzling rapidity, and when he worked with the fierce,
eruptive energy of a great volcano, throwing out new ideas incessantly
with spectacular effect on the arts to which they related. It has always
been a theory with Edison that we sleep altogether too much; but on
the other hand he never, until long past fifty, knew or practiced the
slightest moderation in work or in the use of strong coffee and black
cigars. He has, moreover, while of tender and kindly disposition, never
hesitated to use men up as freely as a Napoleon or Grant; seeing only
the goal of a complete invention or perfected device, to attain which
all else must become subsidiary
