about seven tons. The engines, which have 25 horse power and are of
the double cylinder pattern, are below the floor and connected
directly to the wheels. The wheels are four in number and 31 in. in
diameter. The internal appearance and general arrangement of
machinery, etc., is about that of the ordinary steam dummy. It will
run in either direction, and the exhaust steam is run through a series
of mufflers which suppress the sound, condense the steam and return
the water to the boiler, which occupies the center of the car. The
motor was built in Ghent, Belgium, and cost about $5,000, custom house
duties amounting to about $2,000 more.--_The Railway Review_.

TWENTY-FOUR KNOT STEAMERS.

Probably the most important form of steam machinery is the marine
engine, not only because of the conditions under which it works, but
because of the great power it is called upon to exert. Naturally its
most interesting application is to Atlantic steaming. The success of
the four great liners, Teutonic, Majestic, City of Paris and City of
New York, has stimulated demand, and the Cunard Company has resolved
to add to its fleet, and place two ships on the Atlantic which will
outstrip the racers we have named.

The visitor to the late Naval Exhibition interested in shipping will
have remarked at each of the several exhibits of the great firms a
model of a projected steamer, intended to reduce the present record of
the six days' voyage across the Atlantic--the _ne plus ultra_ at this
time of steam navigation. To secure this present result a continuous
steaming for the six days at 20 knot speed is requisite, not to
mention an extra day or two at each end of the voyage. The City of
Paris and the City of New York, Furst Bismarck, Teutonic and Majestic
are capable of this, with the Umbria and Etruria close behind at 18 to
19 knots. Only ten years ago the average passage, reckoned in the same
way as from land to land--or Queenstown to Sandy Hook--was seven days
with a speed of 17 knots, the performance of such vessels as the
Arizona and Alaska. Twenty years ago the length of the voyage was
estimated as seven and a half to eight days at a speed of 16 knots,
the performance of such vessels as the Germanic and Britannic of the
White Star fleet of 5,000 tons and 5,000 horse power. Thirty years ago
