The Locomotive

Watt’s invention. But the first practical steam
carriage was constructed by W. J. Cugnot, a French-
man, in 1769, for the purpose of transporting artil-
lery. (Fig. 141, Plate 25.)
The cylinders of this engine were 13 inches in
diameter, and the wheels were turned by a ratchet
and pawl. Watt himself had ideas on the subject, and
with the aid of Murdoch he made a model in 1784.
But the demand for engines for driving mills and
factories was so great that he had no time to devote
to the subject. Indeed, he appears to have lost
interest in it.
It was Richard Trevithick, a Cornishman, who
made the most persistent efforts and came nearest
to success. In 1804 he built a locomotive to run
on the Penydarren tramway in South Wales, and
four years later he constructed a circular railway
in London and ran an engine upon it at 12 to
15 miles an hour. For the first time it became
generally understood that an engine would draw a
load on smooth rails, and that so long as the line was
fairly level, no toothed wheels and rack were re-
quired. Trevithick in England and Evans in America
were the first men to use high-pressure steam. And
Trevithick is really the inventor of the locomotive.
The real father of the railway, however, was
George Stephenson, who, like nearly all the inventors
of the eighteenth and early nineteenth centuries,
started life without any advantages of education or
worldly wealth. Born on June 9th, 1781, at Wylam,
near Newcastle-on-Tyne, where his father was engine-
