Incineration is impossible for lack of fuel, and because it would give the range to artillery. The method adopted has been to collect excreta in small buckets, empty gasoline tins and similar receptacles. These are tightly covered and carried to the rear by the troops when relieved, and clean cans are brought forward and put in place by the new troops. The cans containing the excreta are preferably burned in an incinerator at the rear when fuel is available, but when this cannot be done the cans are buried in deep pits and well covered. Lime or iron sulphate or crude oil may be used to cover the excreta. Iron sulphate is a good deodorant. As the dugout is lighted only by a candle or lantern, flies are not attracted in great numbers, but the latrine box should be made fly-tight.
