While opposed by such a powerful array of English scientific wisdom,
the inventor had the satisfaction of submitting his plan to a citizen
of the New World, Mr. Francis B. Ogden,--for many years Consul of the
United States at Liverpool,--who was able to understand its philosophy
and appreciate its importance. Though not an engineer by profession,
Mr. Ogden was distinguished for his eminent attainments in mechanical
science, and is entitled to the honor of having first applied the
important principle of the expansive power of steam, and of having
originated the idea of employing right-angular cranks in marine
engines. His practical experience and long study of the subject--for he
was the first to stem the waters of the Ohio and Mississippi, and the
first to navigate the ocean by the power of steam alone--enabled him at
once to perceive the truth of the inventor's demonstrations. And not
only did he admit their truth, but he also joined Ericsson in
constructing the experimental boat to which we have alluded, and
which the inventor launched into the Thames with the name of the
"Francis B. Ogden," as a token of respect to his Transatlantic friend.

Other circumstances soon occurred which consoled the inventor for his
disappointment in the rejection of the propeller by the British
Admiralty. The subject had been brought to the notice of an officer of
the United States navy. Captain Robert F. Stockton, who was at that
time on a visit to London, and who was induced to accompany him in one
of his experimental excursions on the Thames. Captain Stockton is
entitled to the credit of being the first naval officer who heard,
understood, and dared to act upon the suggestions of Ericsson, as to
the application of the propeller to ships of war. At the first glance,
he saw the important bearings of the invention; and his acute judgment
enabled him at once to predict that it was destined to work a
