truck, low and to the right, using the same elevation and the
same point of aim, when the piece is canted 90 deg. to the right.

Different degrees of canting the piece can be represented by drawing
an arc of a circle through the two marks with the paster as a center.
The second mark will be at a point on this arc corresponding to the
degree of canting the piece.

It is important to know that this effect of canting increases with the
distance from the target.

Fourth Sighting Exercise

=1363.= This exercise is to show the advantage of blackened sights.

In strong sunlight, make a triangle of sighting, using a rifle having
sights worn bright. Then, being careful not to move the rifle, blacken
the sights and make another triangle.

Use dotted lines for the triangle with bright sights and full lines
for the triangle made with blackened sights.

The position and size of the two triangles will plainly show the
advantage of using blackened sights.

Fifth Sighting Exercise

=1364.= This exercise is to illustrate the importance of knowing the
effects of varying degrees of light.

In strong sunlight make a triangle of sighting. Then, being careful
not to move the piece, make another triangle, the target and the man
sighting having first been shaded.

The relative positions of the triangles will show the importance of
knowing the effects of varying degrees of light.

Position and Aiming Drills

=1365. Object.= The object of the position and aiming drills are:

1. To so educate the muscles of the arm and body that the piece,
during the act of aiming, shall be held without restraint, and during
the operation of firing shall not be deflected from the target by any
convulsive or improper movement of the trigger finger or of the body,
arms, or hands.

2. They also establish between the hand and eye such prompt and
intimate connection as will insure that the finger shall act upon the
trigger, giving the final pressure at the exact moment when the top of
the front sight is seen to be directed upon the mark.

3. If at the moment the piece is discharged, it is properly supported
and correctly aimed, the mark will surely be hit.

Since any fairly intelligent man can be taught to aim correctly and to
hold the sights aligned upon the mark with a fair amount of
steadiness, it follows that bad shooting must necessarily arise from
causes other than bad aiming. The chief of these causes is known to be
the deflection gi
