In the very damp regions small drains (rigoles) and cesspools have to be dug to carry off the water, and the trenches themselves must be provided with open “boardwalk” flooring. When not pressed by time and scarcity of material, especially in winter, all possible means should be adopted to prevent the men from standing too long in water. Dampness, more than cold, is responsible for frostbitten limbs.

In the parapets of trenches that are expected to last some time, loopholes are made by inserting pieces of sheet-steel with openings to allow the passage of a gun barrel. Each opening closes with a small door which remains shut except when the loophole is in use ([Fig. 4]).
