Suppose you are out hunting, and that you see a big buck on a distant
hill. Suppose that it is exactly 600 yards distant from you, that you
are an expert shot, and that you set your sights at 400 yards and fire.
Will you hit the deer or not? You must know how to guess accurately the
distance to a deer, or a man, or anything else, if you propose to have
any reasonable hope of hitting it.
The art of estimat
ng distances with the eye can be improved by
practice. When you are in ranks, observe continually your surroundings.
Call attention to and make estimates of the distances to all the
prominent objects in view. Others near you will become interested, and
the interest will soon spread to the entire company. It will be
necessary for the objects to be pointed out to those interested. This in
itself is a difficult thing to do. To be able quickly to see distant
objects that are being pointed out is a military accomplishment which
all soldiers should possess and which comes only with practice.
