Platoon commanders will go over every part of the trench several times daily with the squad leaders of the various sections and decide upon the repairs and improvements to be made. A complete and thorough police will be made prior to being relieved. All refuse will be removed. Fired cartridges will be disposed of, as they might get imbedded in the trench floor and hinder subsequent digging. Each squad leader will be held strictly responsible for the state of police of the section of trench occupied by his squad. LATRINES Latrines are located at convenient points in the trenches. For the men on duty in the first line they are generally dug to the flank of a connecting trench and connected therewith by a passageway. Their location is plainly marked. The rules of sanitation are even more strictly observed in trenches than they are in soldier camps. The trenches and passageways must not under any circumstances be defiled. Latrines should be kept clean and sanitary. They will be carefully protected from flies. The free use of chloride of lime daily is an absolute necessity. MAPS A complete detailed plan of our own trenches and as much as is known of those of the enemy opposite should be made, and be available for study and to refer to in making reports. Every bay of the trench should be numbered, every traverse lettered. All junction points of fire and communicating trenches, all dugouts, all posts, mortar positions, machine-guns positions, observation posts, and any points that it may be necessary to refer to in reports should be designated by numbers. FROST BITE; CHILLED FEET The causes are: 1. Prolonged standing in cold water or liquid mud. 2. Tight boots and leggings, that interfere with the blood circulation. PREVENTION 1. Before going into the trenches wash the feet and legs and dry them thoroughly. The British Army has an issue of an anti-freeze mixture which will probably be issued to our troops also. The feet and legs should be rubbed with it. Put on perfectly dry socks. An extra pair of dry socks should be carried. 2. During the period of service in the trenches the feet should be treated in this manner from time to time. 3. When the feet are cold, hot water will not be used for washing nor will they be held close to a fire. 4. Rubber boots must be worn only in the trenches. On no account must they be worn while on reserve. TRENCH SOLDIERS' CREED To be of the greatest effectiveness in the trench every soldier, personally and collectively, must be able to adopt the following creed and live up to it:
