The high pressure steam engine in its stationary form is almost
ubiquitous in America. In all great iron and steel works, in all
factories, in all plants for lighting cities with electricity, in
brief, wherever in the United States great power in compact form is
wanted, there will be found the high pressure steam engine furnishing
all the power that is required, and more, too, if more is demanded,
because it appears to be equal to every human requisition. But go
beyond America. Go to Great Britain, and the American steam
engine--although it is not termed American in Great Britain--will be
found fast superseding the English engine--in other words, James
Watt's condensing engine. It is the same the world over. On all the
earth there is not a steam locomotive that could turn a wheel but for
the fact that, in common with every locomotive from the earliest
introduction of that invention, it is simply the American steam engine
put on wheels, and it was first put on wheels by its American
inventor, Oliver Evans, being the same Oliver Evans to whom the State
of Maryland granted the before mentioned patent of 1787.

He is the same Oliver Evans whom Elijah Galloway, the British writer
on the steam engine, compared with James Watt as to the authorship of
the locomotive, or rather "steam carriage," as the locomotive was in
those days termed. After showing the unfitness of Mr. Watt's low
pressure steam engine for locomotive purposes, Mr. Galloway, more than
fifty years ago, wrote: "We have made these remarks in this place in
order to set at rest the title of Mr. Watt to the invention of steam
carriages. And, taking for our rule that the party who first attempted
them in practice by mechanical arrangements of his own is entitled to
the reputation of being their inventor, Mr. Oliver Evans, of America,
appears to us to be the person to whom that honor is due." He is the
