GENERAL OBSERVATIONS ON GUN-PITS.

In forming the epaulement, leave a berme of at least a foot; and, when there is time, level and ram the earth, which, in front of the muzzle, should not be more than three and one half feet above the bottom of the pit. If there are side trenches, the earth in front of them should be high enough to afford complete protection to the men occupying them.

Pockets for the reception of the ammunition are very important in saving the ammunition from water which may accumulate, and from the fire of the enemy.

The field of fire should not be less than 90 degrees.

Avoid narrow embrasures as presenting an easy mark, and as likely to draw the fire of the enemy.

Cover should first be provided for the men and horses; then for the material.

If the position is occupied for some time, strengthen the parapet by earth from a ditch in front. Prolong the lateral trenches of the adjacent pits until they meet, forming a continuous parapet; if possible, plank or macadamize the bottom of the pit. Traverses between the guns will be found effective.
