cupy more than half the length of
the vessel, leaving only space enough for the accommodation of the officers
and crew at the ends. The armament consists of five Hotchkiss revolving
guns on each side, and a 4 in. gun at each end, the latter being so
arranged that each one can sweep half the horizon.
The keel was laid in August, 1885, and the ship was launched July 29,
1886, on which occasion it was christened Greif. On the trial trip it was
found that the slender shape of the vessel adapted it for the development
of a very high rate of speed under favorable conditions, when it can make
at least 22 knots an hour, so that the speed of 19 knots an hour guaranteed
by the builders can certainly be reached, even when traveling at a
disadvantage. In spite of its great length, the Greif can be easily
maneuvered. When moving forward at full speed, it can be made to describe a
circle by proper manipulation of the rudder, and by turning one screw
forward and the other backward, the ship can be turned in a channel of its
own length.
[Illustration: THE NEW GERMAN WAR STEAMER GREIF.]
A large and rapid cruiser, also for the German navy, is being built by the
corporation "Germania". This vessel is of about the same length as the
Greif, has more than double its displacement, and will make 18 knots an
hour, an unusual rate of speed for a vessel of its class. It will be
launched by the last of the summer or early in the fall.

TWIN SCREW TORPEDO BOAT.
We give several illustrations of a sea going twin screw torpedo boat lately
built for the Italian government by Messrs. Yarrow & Co., of Poplar. The
vessel in question is 140 ft. long by 14 ft. wide, and her displacement
approaches close on 100 tons. The engines are of the compound surface
condensing type ordinarily fitted by this firm in their torpedo boats,
excepting where triple compounds are fitted. The general arrangement is
shown by the sectional plan. As will be noticed, there are two boilers, one
before and the other aft of the engines, and either boiler is arranged to
supply either or both the engines. Yarrow's patent water tight ash pans are
fitted to each boiler, to prevent the fire being extinguished by a sudden
influx of water into the stokehold. There is an independent centrifugal
pumping engine arranged to take its suction from any compartment of the
boat. There are also steam ejectors and hand pumps to each compartmen
