ted like cavalry
patrols and should be trained in accordance with the Cavalry Drill
Regulations.

For distant patrolling, a mounted patrol under an officer should be
used.

622. For controlling the movements of the patrol, the leader should,
when necessary, make use of the arm signals prescribed in these
regulations.

On account of the short distances separating them, ordinary
communication between members of the patrol is best effected quietly
by word of mouth.

When a member of a patrol is sent to a distant point, communication
may be effected by means of simple, prearranged signals.

When practicable, the patrol leader may communicate with the main body
by means of visual signaling.

PART III.--MARCHES AND CAMPS.

MARCHES.

_TRAINING AND DISCIPLINE._

623. Marching constitutes the principal occupation of troops in
campaign and is one of the heaviest causes of loss. This loss may be
materially reduced by proper training and by the proper conduct of the
march.

624. The training of infantry should consist of systematic physical
exercises to develop the general physique and of actual marching to
accustom men to the fatigue of bearing arms and equipment.

Before mobilization troops should be kept in good physical condition
and so practiced as to teach them thoroughly the principles of
marching. At the first opportunity after mobilization the men should
be hardened to cover long distances without loss.

625. With new or untrained troops, the process of hardening the men to
this work must be gradual. Immediately after being mustered into the
service the physical exercises and marching should be begun.
Ten-minute periods of vigorous setting-up exercises should be given
three times a day to loosen and develop the muscles. One march should
be made each day, with full equipment, beginning with a distance of 2
or 3 miles and increasing the distance daily as the troops become
hardened, until a full day's march under full equipment may be made
without exhaustion.

626. A long march should not be made with untrained troops. If a long
distance must be covered in a few days, the first march should be
short, the length being increased each succeeding day.

627. Special attention should be paid to the fitting of shoes and the
care of feet. Shoes should not be too wide or too short. Sores and
blisters on the feet should be promptly dressed during halts. At the
end of the march feet should be bathed an
