tend outboard of the boiler and engine
spaces. There are twenty watertight COM
partments below the protective deck for
ward Of the machinery space and eighteen
similarly situated aft. Tie space between
the protective and berth decks comprises
over seventy-five watertight compartments.
A watertight center line bulkhead extends
the full length OF the machinery space, thus
placing the port and starb0ard engines in
separate compartments.
The fire and drainage system is complete
and steam pumping arrangements are pro-
vided by connection to the main circulating
pump in addition to powerful hand pumps.
OFFICERS QUARTERS.
Quarters for twenty-five officers are pro-
vided. The Admiral'S and Captains cabins
and Stato-T0ons are in the after part of the
superstructure and are conveniently ar
ranged and fitted. The ward-room is on
the after berth deck, the state-rooms are
fitted as usual in the service but the fitting
Of a separate athwartship dining-room will
materially add to the comfort of the ward
room officers.
The accommodations for the crew of AL
men IN the forward part Of the superstruc-
ture and forward beTth-deek are spacious,
and all care has been exercised to provide
comfortable and healthful quarters.
The magazines and shell rooms are loca-
ted to provide for the convenient serving
Of the guns.

lection is afforded to the machinery by the
location OF the bnnkeTS along tile side be-

MACHINERY.
The machinery. as designed by the
Bureau Of Steam Engineering, is intended
TO develop 1850 indicated horsepower
when at its maximum, which will propel
the ship about 20A knots.
The engines are two in number, of the in
yerted vertical direct acting type, triple ex-
pansion, one on each shaft, the ship being
propelled by twin screws.
The diameters OF the cylinders are AZ, SO
and 92 inches by 42-inch stroke. They are
intended to be driven 128 revolutions per
minute. Each cylinder rests upon three
columns, giving easy access to the front of
the moving parts. Piston valves are used,
and all working parts. bed plates and
frames, are of steel. The shafting is of
forged steel, hollow.
THE BOILERS.
The boilers are six in number-two sim
gle-ended and four dOuble-ended - the
larger ones having eight furnaces and the
smaller four. They are 10 feet, 3 inches in
diameter, cylindrical, and are intended to
ii.
No boilers Of this size and pressure have
hitherto been built in the United States.
The steel Of the shells is l 1864 inches
thick.
With the full coal supply, 1900 tons, at
2OA knots speed and under forced draught
the vessel will travel 2l9l.S So knots in nearly
four and a hall days. AT ten-knOt cruis-
Ing speed, unGer natural draught ana full
coal supply, her radius Of action would be
nearly $4,000 knots, with an endurance of
about 80 days.
ARMAMENT.
The main battery consists of two S-inch
breech-l0adng rifles and ten 4-ineh breech-
loading rifles. The 6-ineh rifles are mounted
on the center line in barbette turrets, four
inches thick, and one at the forward and
one at this after end of the superstructure,
and train from directly ahead or asteru to
fifty degrees on each side, aba t or before
the beam, respectively. The ammunition
Is supplied through armOred tubes three
inches thlck, which permit loading in any
position. The 4-inch guns are noun ted on
improved central pivot mounts, and are
protected by fixed segmental shields four
inches thick; four OF these guns forward
have a fire from directly ahead to sixty
three degrees abaft the beam; the four
after guns have similar train before the
beam; the two 4-inch guns amidship have
brUadside train through 146 degrees. The
fire of all the forward aud after guns, re-
spectively, can be concentrated upon an
object the length of the vessel directly
ahead or astern.
SECONDARY BATTERY.
The secondary battery consists OF eight g.
Founders, six 3-pounders aud fourteen ma
chlne-guns, mounted TO be clear of the
smoke and fire OF the main battery and for
efficient action against boat attacks. Wher-
ever practicable protection is afforded the
machlne-guns by plating 2h inches thick.
In each of the lower mllItary-tOps are
mounted 37-millimeter Maxim and l.
pound Hotchkiss.
An allowance Of $50 rounds will be pro-
vided for each of the S-Inch and 4-inch
guns. An average of about 5000 rounds is
allowed for eacn Of the guns in the second
ary battery.
The torpedo outfit consists of six launch
ing tubes for Howell automobile torpedoes
-One fixed at the stem, one at the stern and
two training-tubes on each brOadside.
