give promise of developing a speed of from 23 to 25 knots."

In the Russian boat recently built at Glasgow, progress in this direction
is also seen in the 148 ft. length, 17 ft. beam, the maneuvering powers and
safety element of the twin screws. But while the boat is fitted for the 19
ft. torpedo, a weapon of increased range and heavier explosive charge, it
suffers from the impossibility of broadside fire and the disadvantages that
Gallwey has named: "The great length of this torpedo, however, makes it a
very unhandy weapon for a boat, besides which its extra weight limits the
number which can be carried."

While perhaps Messrs. Thomson have been the first to show the performance
of a twin screw torpedo boat in England, the one completed in June last by
Yarrow for the Japanese government recalls the intelligence that Japan has
exercised in the selection of types.

Commencing as far back as nine years ago, the Japanese were probably the
first to introduce sea-going boats, and they have been the first power to
initiate the armor type, one of which was shipped last summer to be put
together in Japan. As before stated, it was built by Messrs. Yarrow and
Co., was 166 ft. long, 19 ft. beam, with twin screws, 1 in. steel armor,
double engines, with bow and broadside torpedo guns, the latter so arranged
as to greatly increase their efficiency.

While the advances are not restricted to the English builders, a glance at
the points to which Thornycroft and Yarrow have brought their improvements
up to the present time will indicate that their achievements are not only
equal to but greater than those of any other builders.

The former has boats under construction 148 ft. long, 15 ft. beam, to make
420 revolutions with 130 lb. of steam, the guaranteed speed being 23 knots
on a continuous run of two hours' duration, with a load of 15 tons. They
will have triple-expansion or compound direct-acting surface-condensing
engines and twin screws, Thornycroft's patent tubular boilers, double
rudders, electric search lights, three masts and sails.

While the armaments of the various boats differ, Thornycroft is prepared to
fit the launching tubes with either air or powder impulse, to mount the
tubes forward or on deck, and also the fittings for machine and rapid
firing guns.

Yarrow and Co. have contracted for boats varying in length from 117 ft. to
166 ft., with fittings and armament as may be required. They have obtained
excellent resu
