Repairs or alterations of the parapet should be reported at once by the section commander to the platoon commander, who will report it to superior authority.  Repairing of trenches, fatigue, etc., will be carried on either by day or night according to company arrangement.  Certain hours will be allotted for these tasks and no man is to be employed upon any kind of work out of these hours.  No man should leave his post in the trenches at any time without the permission of the non-commissioned officer in charge of that post.  At night there should be at least one sentry post to each ten yards of parapet.  At night, double sentries should be posted if possible, and no sentry should be kept on duty for longer than an hour at a time.  The arrangement should be such that when one sentry is doing his last half hour, his comrade will be doing his first half hour.

Sentries at night should always have their rifles resting on the parapet, ready to fire at a moment’s notice.  As few sentries as possible should be posted by day, so as to give as much rest as possible to the remainder of the men.

By day any existing loop-holes may be used by a sentry for observation purposes, but this must be strictly prohibited at night, when the sentry must look over the parapet.  If a sentry is continually fired at, the section commander will post him in another position, but not too far from his original position.  There is no excuse for a man going to sleep on sentry duty; if he is sick he should report the fact to the non-commissioned officer, who will report to superior authority.

An armed party of the enemy approaching the trench under a flag of truce should be halted at a distance, ordered to lay down their arms, and the matter at once reported to the company commander.  If the party fails to halt when ordered to do so, or does not convey a flag of truce, they should be fired upon.  An unarmed party should be halted in the same way.  It is not necessary to challenge at night; open fire at once.  This is modified only by special instructions.

Men especially picked for listening patrols and sharp-shooters will be given special privileges.  All loud talking must be checked at night by officers and non-commissioned officers.  All working parties must wear their equipment and carry their rifles.  All picks and shovels will be returned after use to the company store room.  Ration parties and parties carrying materials for repairs, etc., need not wear their equipment or carry rifles; they should be accompanied by a fully armed non-commissioned officer as an escort.  Not more than 20 men are to be away from the company at one time; one non-commissioned officer and four men per platoon.

Rifles must be kept clean and in good condition while in the trenches.  They will be cleaned every morning during an hour appointed by the company commander for the purpose.  Platoon commanders will be responsible that section commanders superintend this work.  All rifles except those used by sentries are to be kept in racks during the day.
