he front of the thighs is
directly over the point of the toes; the hips are square and the waist
is extended by the erection of the entire spine, but never to such a
degree that mobility of the waist is lost.

In extending the spine, the chest is naturally arched and the abdomen
is drawn in, but never to the extent where it interferes with
respiration.

In extending the spinal column, the shoulders must not be raised, but
held loosely in normal position and forced back until the points of
the shoulders are at right angles with an anterior-posterior plane
running through the shoulders.

The chin should be square; i. e., horizontal and forced back enough to
bring the neck in a vertical plane; the eyes fixed to the front and
the object on which they are fixed must be at their own height
whenever the nature of the terrain permits it.

When properly assumed, a vertical line drawn from the top of the head
should pass in front of the ear, just in front of the shoulder and of
the thigh, and find its base at the balls of the feet.

All muscles should be contracted only enough to maintain this
position, which at all times should be a lithesome one, that can be
maintained for a long period without fatigue--one that makes for
activity and that is based upon a correct anatomical and physiological
basis.

Instructors will correct the position of attention of every man
individually and they will ascertain, when the position has been
properly assumed, whether the men are "on their toes," i. e., carrying
the weight on the balls of the feet, whether they are able to respire
properly, and whether they find a strain across the small of the back,
which should be as flat as possible. This should be repeated until the
men are able to assume the position correctly without restraint or
rigidity.

At the command =rest= or =at ease= the men, while carrying out the
provisions of the drill regulations, should be cautioned to avoid
assuming any position that has a tendency to nullify the object of the
position of attention; standing on leg for instance; allowing the
shoulders to slope forward; drooping the head; folding arms across
chest, etc. The weight should always be distributed equally upon both
legs; the head, trunk, and shoulders remain erect and the arms held in
a position that does not restrict the chest or derange the shoulders.
The positions illustrated here have been found most efficacious. Figs.
