ft.); the tipping boxes have therefore a breadth of only 2 ft., and
contain 7¼ cubic feet. The boxes are perfectly balanced, and are most
easily emptied. The wagons run on two lines, the one being for the
loaded trains, and the other for the empty trains.

The engineers and inspectors, in the discharge of their duties, make use
of the Liliputian carriages. The feet of the travelers go between the
wheels, and are nearly on a level with the rails; nevertheless, they are
tolerably comfortable. They are certainly the smallest carriages for
passengers that have ever been built; and the builder even prophesies
that these will be the first to enter into England through the Channel
Tunnel.

One of the most important uses to which a narrow gauge line can be put
is that of a military railway. The Dutch, Russian, and French
Governments have tried it for the transporting of provisions, of war
material, and of the wounded in their recent campaigns. In Sumatra, in
Turkestan, and in Tunis these military railroads have excited much
interest, and have so fully established their value that this paper may
confine itself to a short description.

The campaign of the Russians against the Turcomans presented two great
difficulties; these were the questions of crossing districts in which
water was extremely scarce or failed entirely, and of victualing the
expeditionary forces. This latter object was completely effected by
means of 67 miles of railway, 20 in. gauge, 14 lb. steel rails, with 500
carriages for food, water, and passengers. The rails were laid simply on
the sand, so that small locomotives could not be used, and were obliged
to be replaced by Kirghiz horses, which drew with ease from 1,800 lb. to
2,200 lb. weight for 25 miles per day.
