distance between the tents of each row will be 2 or
3 feet; the distance between the tents of one company and those of
another, from 4 to 6 feet.

Fig. 11 is the camp of a squadron of cavalry. A single company encamping
alone, would be arranged in the same way as an entire squadron. The
horses are picketed in two lines parallel to the tents, and at a
distance from them of about 12 feet. The forage is placed between the
tents. A squadron of two companies will occupy a front of about 180
feet. The fires, or company kitchens, should be 50 or 60 feet in rear of
the non-commissioned officers' tents.

Fig 12 is the camp of two batteries of foot artillery, or two companies
of foot engineers.

[The plan of encampment for artillery, as given in the "Instruction of
U.S. Field Artillery, horse and foot," may be employed where a single
battery encamps by itself, or where only the skeleton of companies is
maintained; but it will be found exceedingly inconvenient, where a full
battery, with a large train, encamps on the same line with other troops.
The plan we have given is that which is employed in most European
services.]

Fig. 13.--In this plan for mounted artillery and engineers, the fires
are so arranged as to expose the ammunition as little as possible to the
sparks from the kitchens.
