same as above.
3. KNEES EXTENDED WITHOUT STIFFNESS.--Muscles should be contracted
just enough to keep the knees straight. If locked, men tire easily and
faint if at attention a long time.
4. THE TRUNK ERECT UPON THE HIPS, the spine extended throughout its
entire length; the buttocks well forward.
The position of the trunk, spine and buttocks is most essential. In
extending the spine the men must feel that the trunk is being
_stretched up_ from the waist until the back is as straight as it can
be made.
In stretching the spine the _chest_ should be _arched_ and raised,
_without_, however, _raising the shoulders or interfering with natural
respiration_.
5. SHOULDERS FALLING NATURALLY and moved back until they are square.
Being square, means having the shoulder ridge and the point of the
shoulder at right angles to a general anterior-posterior plane running
through the body. They should never be forced back of this plane, but
out rather in line with it.
6. ARMS HANGING NATURALLY, thumbs against the seams of the trousers,
fingers extended, and back of hand turned out.
The arms must not be forcibly extended nor held rigidly; if they are,
a compensating faulty curve will occur in the lumbar region.
7. HEAD ERECT, CHIN RAISED until neck is vertical, eyes fixed upon
some object at their own height.
Every tendency to draw the chin in must be counteracted.
8. When this position is correctly assumed, the men will be taught to
_incline the body forward_ until the weight rests chiefly upon the
balls of the feet, heels resting lightly upon the ground.
When properly assumed, a vertical line drawn from the top of the head
should pass in front of the ear, shoulder and thighs, and find its
base at the balls of the feet.
Every tendency toward rigidity _must be avoided_; all muscles are
contracted only enough to maintain this position, which is one of
co-ordination, of _physical and mental alertness_, that makes for
mobility, activity and grace. A man who faints standing at attention
has not taken the proper position.

Rests.

POSITION OF REST AND AT EASE.--When men are standing _at rest_ or _at
ease_ they must be cautioned to avoid assuming any position that will
nullify the object of the position of Attention. Standing on one leg,
folding arms, allowing shoulders or head to droop forward, must be
discountenanced persistently until the men form the habit of resting
with feet separated but on
