Trenches and ditches.— (i) A trench is an excavation inrear of the covering mass; a ditch is one in front of it. (2) Cover is more rapidly gained by the use of a trench, as itwill be obtained by the excavation plus the height of earth thrownimmediately in front. (3) A ditch might provide the earth for the parapet in worksof a more important nature, and at points which are purely de-. Plate 25. Art. 3.

The profileselected will depend upon the object the work has to fulfill, uponthe projectiles it may have to withstand, and upon the nature ofthe surrounding ground. (2) The profile may be formed also of a trench and a ditch,the men working on each side of the parapet and throwing the earthupon the intermediate space.
