A gutter should be formed in the trench,usually at the back, and the bottom of the trench sloped to it. Any water collecting in it should, where possible, be led offto lower ground, otherwise into soak pits, which may be about2 feet or 3 feet in diameter and 3 feet deep. Communication Trenches. 78. If time admits covered communications should be Communi-arranfTed behind the firine line. These, while concealing the cationmovements of the defenders, will also permit of the firing line being withdrawn altogether while the artillery bombardment isgoing on.

They may require parapets on both sides, and wher
