sent them to England in 1794-5 by Mr. Joseph Stacy Sampson, of Boston, with the hope that some British engineer would approve and conjointly with him take out patents for the inventions.  Mr. Sampson died in England, but not until after he had extensively exhibited Mr. Evans’ plans, apparently, however, without success.  After Mr. Sampson’s death Trevithick and Vivian took out a patent for a high pressure steam engine.  This could happen and yet the invention be original with them.

But they introduced into Cornwall a form of boiler hitherto unknown in Great Britain, namely, the cylindrical flue boiler, which Oliver Evans had invented and used in America years before the names of Trevithick and Vivian were associated with the steam engine.  Hence, they were charged over fifty years ago with having stolen the invention of Mr. Evans, and the charge has never been refuted.  Hence when British writers ignore the just claims of Oliver Evans and assert for Trevithick and Vivian the authorship of the high pressure steam engine and the locomotive, they thereby substantially acknowledge the American origin of both inventions.  They are not only of American origin, but their author, although born in 1755, was nevertheless an American of the second generation, seeing that he was descended from the Rev. Dr. Evans Evans, who in the earlier days of the colony of Pennsylvania came out to take charge of the affairs of the Episcopal Church in Pennsylvania.

The writer has thus shown that with the patent granted by the State of Maryland to Oliver Evans in 1787 were associated—­first, the double acting high pressure steam engine, which to-day is the standard steam engine of the world; second, the locomotive, that is in worldwide use; third, the steam railway system, which pervades the world; fourth, the high pressure steamboat, which term embraces all the great ocean steamships that are actuated by the compound steam engine, as well as all the steamships on the Mississippi and its branches.

The time and opportunity has now arrived to assert before all the world the American origin of these universally beneficent inventions.  Such a demonstration should be made, if only for the instruction of the rising generation.  Not a school book has fallen into the hands of the writer that correctly sets forth the origin of the subject matter of this paper.  He apprehends that it is the same with the books used in colleges and universities, for otherwise how could that parody on the history of the locomotive, called “The Life of George Stephenson, Railway Engineer,” by Samuel Smiles, have met such unbounded success?  To the amazement of the writer, a learned professor in one of the most important institutions of learning in the country did, in a lecture, quote Smiles as authority on a point bearing on the history of the locomotive!  It is true that he made amends by adding, when his lecture was published, a counter statement; but that such a man should have seriously
