(b) When shelters are made the required space from the ground level downward will be cut out and a roof supported on reliable posts will be made.
9. SANITATION.—(a) The importance of strict attention to sanitation should be impressed on all ranks.
(b) Empty tins or other refuse will be collected in receptacles kept for the purpose in the trenches and buried in a refuse pit.
(c) Latrines will be constructed in trenches leading from communication trenches. Where the bucket system is employed, chloride of lime or creosol will be freely used. The soil will be removed at night and buried in a deep pit well away from the trenches; these pits will be filled in when nearly full and labeled.
(d) The commanding officer is responsible for sanitation in his unit and the medical officer will advise him in sanitary matters, making daily inspections of latrines, refuse pits, and water arrangements. Under the medical officer latrines and refuse pits will be attended to by the regimental sanitary men and water duties by the R. A. M. C. details attached.
10. TIME-TABLES AND ORGANIZATION OF WORK.—(a) A time-table will be drawn up by each company commander. In this time-table he will allot hours of work, rest, and meals.
(b) Working parties will be properly organized. Definite tasks will be allotted. Each commander of a working party should know what work is expected from his party before the hour appointed to commence, so that no time is wasted in getting to work.
(c) Unless it can not be avoided, men should never be taken for sentry duty without having had a reasonable period of rest, and when this becomes necessary a report should be made to the C. O.
11. LOG BOOKS AND TRENCH STORE BOOKS.—(a) Each company commander will keep a log book in which will be entered up daily the work done. This log book will be handed over from one commander to another on relief.
(b) A trench store book will also be kept in which will be entered up all trench stores issued to the company. On relief, the incoming company commander will give a receipt to the outgoing commander for all trench stores taken over.
