The latest plan to improve the draft of
the furnaces of ocean steamers is to in
crease the height of the smoke pipes.
The new steamer Scot, of the Cape Mail
Line, is provided with smoke pipes 100
feet high above the CRATES, being the
loftiest pipes ever put into steamer. A

Is thus obtained, all the steam needed is
easily secured, and the use of fans is dis
pensed with. Her speed is nineteen
knots.
Bombay has the greatest piece of solid
masonry construction that the world has
seen in modern times. For years past
the water supply of Bombay depended
upon works known to be defective, in.
volving the possibility of a water famine.
A consultation of eminent engineers was
held, under the direction of the Govern.
ment, with the result that a large dam
was determined on to inclose the water
shed of the valley which drains into the
sea south of Bombay.
At Sophia experiments have been made
in the last four weeks to ascertain the ac-
curacy of the rapid-fring cannon recently
received from the Gruson Works in
Magdeburg. At distance of 5000 feet
target representing two field cannon
and ten men was almost completely de-
molished by twenty-five shots. A line
of thirty wooden soldiers, lying six feet
apart, so that only the heads were in
sight of the marksmcn, received twenty
six loads of chain shot and nine of shrap-
nell. Twenty of the chain shot and forty
one pieces of shrapnell struck fourteen
