essary to give a rate of 2,
2-1/2, 2-3/4 and 3 miles per hour, is quickly and easily obtained by
multiplying 35 (1/5) by these numbers.]

In hot, sultry weather, with the men carrying the full pack, the rate
of march would naturally be considerably less than on a cool day, with
the command not carrying the pack. It is most important that these and
other considerations affecting the rate of march be constantly borne
in mind by the officer in command of the column, who should indicate
to the commander of the leading company the number of steps to be
taken per minute. In indicating the number of steps to be taken per
minute, it should be considered whether the men at the head of the
leading company are the average, above the average, or below the
average in height. A short man, for example, would probably have to
take 100 steps a minute to keep up with a tall man walking at the rate
of 90 steps per minute.

=1221. Marching capacity.= The average marching capacity of Infantry
is about 15 miles a day, but in extensive operations, involving large
bodies of troops, the average is about 12 miles a day. Small commands
of seasoned Infantry marching on good roads in cool weather can
average about 20 miles a day.

=1222. Halts.= A halt of 15 minutes should be made after the first
half or three quarters of an hour of marching to enable the men to
attend to the calls of nature and adjust their clothing. Judgment must
be exercised in selecting the place for this halt; it should not be
made in a village or other place where its object would be defeated.

After the first halt a halt of 10 minutes is made in each hour, that
is, the troops march 50 minutes and then halt 10. Of course, the
number and length of halts should be varied according to the weather,
condition of the roads and the equipment carried by the men. In the
tropics the best results are often obtained by marching 45 minutes and
halting 15.

When the day's march will run well into the afternoon, a halt of about
one hour should be made at noon and the men allowed to eat.

Places for long halts should be selected with care; woods, water and
shade are desirable features. Arms are stacked and equipments removed.

Halts should not be made in or near towns or villages unless to
procure water or supplies, and when so made, the men remain in column,
details being sent for whatever is necessary.

In hot weather, especially in the tropics, it may be advisable in the
case of
