was comparatively smooth, and the Bronx continued on her course. At the
last bi-hourly heaving of the log, she was making sixteen knots an hour.
The captain went into the engine room, where he found Mr. Gawl, one of
the chief's two assistants, on duty. This officer informed him that no
effort had been made to increase the speed of the steamer, and that she
was under no strain whatever. The engine had been thoroughly overhauled,
as well as every other part of the vessel, and every improvement that
talent and experience suggested had been made. It now appeared that the
engine had been greatly benefited by whatever changes had been made.
These improvements had been explained to the commander by Mr. Sampson

for he preferred to let the speed of the vessel speak for itself; and
this was what it appeared to be doing at the present time.

Christy walked the deck for some time, observing everything that
presented itself, and taking especial notice of the working of the
vessel. Though he made no claims to any superior skill, he was really an
expert, and the many days and months he had passed in the companionship
of Paul Vapoor in studying the movements of engines and hulls had made

as the present speed of the Bronx indicated. He had ambition enough to
hope that he should be able to distinguish himself in this brief period,
