which is capable of driving the vessel
over Is knots per hour. As Messrs.
Raeburn & Verel are, with their super
intendent, strong believers in plenty
of boiler power, two exceptionally large,
single-ended boilers, Il feet in diameter
by II feet long, fitted with Howden 5
system of forced draught, supply steam
at $50 lbs. working pressure. The enor-
nous fan for supplying air to the fur
naces, with its two engines running at
$50 revolutions per minute, is a sight
in itself, and placed as it is in the
engineroom, it fulfls a dual parpose,

cold current rushing down the four
25-inch ventilators' fitted in the engine
room.
In the stokehold. one looks in vain
for any sign of furnace fires, for the
ashpits being closed, none can be seen,
while the presence of two 3O-inch ven
tilators makes the whole boilerroom
cool and comfortable. The dreaded.
harassing labor of hosting ashes. which
causes much perturbation of spirit and
profane, if ornamental, language, does
not exist in this ship, for here again
consideration for the men has stepped
in and provided a substitute for human
muscle, by fitting one of Railton,
Campbell & Co.'S patent silent ash
hoists, which lifts the ashes and dis
charges them through a chute in the
ships side below the loadwater line,
without making her appear to have
just passed through a shower of Vesu-
Wan lava. To obviate the use of salt
water feed, an evaporator OF % tons

with Weir s feed pumps and feed heater, |

ers. a desire to have a sufiiciency Of |
ballast is one Of the weak points of |
the owners of the Scottish Monarch, |
and when we mention that this steam
er carries 2l25 tons of water ballast,
anS that she draws 10 feet with all
her tanks and bunker spaces full, it
will be seen that they have given
practical expression to their ideas. To
this ballast rapidly, duplex
pumps, capable of throwing out 200
tons per hour, have been fitted.
FOR HANDLING CARGO.
One of the most important of all
on a cargo steamer is Of
necessity the appliances for dealing
with cargoes, and in this, as in others.
/ very successful effort has been made
% fit only the very latest and best
ype for its purpose. a large donkey
1oiler of the marine type, IL 6~%l1',
placed in the boilerroom, supplies steam
It 100 lbs. pressure to the windlass,
vinches, and all auxiliary machinery.
Two of Clarke Chapman & Co. 5 7"Sl2"
vinches with Is" main drums and 20"
drums are placed at each
over which are double der
icks, each capable of taking a safe
working load of tons, with wire
unners. All gins and heel blocks are
TIED with Reds patent self-lubricat-
ny sheaves, each 10" in diameter.
All the winches and the windlass ex

finch condensers, placed in the engine
Dom. Indeed, with view to economy,
Il the auxiliary machinery and steam
eaters are made to exhaust into the
