f a mile. The safety-valve should, at the same time, be
eased off to 35 lbs.

If the train is brought into the Station by a tow-rope, great care must
be taken to stretch the rope gradually by a gentle advance of the Engine,
which must be stopped at a signal from the tow-rope man.

It would be prudent to conduct the examination described at the
commencement, directly the Engine arrives at the Station, in order to
leave time for any repair which may be required.

When an Engine is running the last trip for the day, no fuel need be put
on for the last 10, 15, or 20 miles, according as the duty is heavy or
light; indeed, the fire may be nearly run out by the time the Engine
stops, if the gradients, &c., are favourable. For a considerable
distance before stopping both pumps should be at work, so that the water
in the boiler may be at or above the top cock when the Engine stops, and
the safety-valve should be eased off to 25 lbs. per square inch.

On stopping over the pit, the fire is drawn by opening the fire-door,
introducing the arrow-headed poker through the fire-bars, and pulling up
two or three of them from the bottom of the furnace, by which room will
be allowed for the rest to be separated, and the fire fall through into
the ash-pan, from which it is raked out by the Stoker. The practice of
blowing off all the water from a boiler by the pressure of the steam
should never be allowed, without an express order from the Superintendent
of Locomotives, when the boiler is unusually full of mud; as, if
frequently practised, it will seriously injure the fire-box and tubes.

THE MANAGEMENT OF A LOCOMOTIVE ENGINE IN CASES OF ACCIDENT.

An Engine is liable to several accidents while running, and it is
important that the Engine-man should know how to act promptly under the
circumstances. In the following list several cases are enumerated, with
the particular steps to be taken in each.

1. _The bursting of a tube_.--The Engine-man should stop the Engine, and
drive a plug into each end of the tube. It frequently happens that the
water and steam blow out with so much force, that it is impossible even
to discover the defective tube: by running the Engine for a short
distance with both pumps acting, the pressure of the steam will perhaps
be sufficiently reduced to enable the Engine-man to work with safety; but
if the escape of water and steam is still too great to do so, he must run
his Engine and train, if possible,
