A list of trench stores, ammunition, etc., will also be drawn up ready for handing over. All stores should be carefully stacked in a convenient place. Ammunition, Very lights, sandbags, etc., sufficient for at least 24 hours consumption, should invariably be handed over to the relieving unit.
(k) The following constitute trench stores and will be handed over on relief:
| S. A. A. | Rifle racks. | ||
| Shovels. | Rifle grenade firing stands. | ||
| Picks. | Hand grenades. | ||

Battalion entrenching tools will not be taken to the trenches. Should the existing tools in the trenches be considered insufficient, application should be made to brigade headquarters for a further supply.
2. SENTRIES.—As a general rule, the following numbers of sentries will be posted:
By day.—One sentry for every 3 bays, exclusive of bombers, snipers, and machine gunners.
By night, in a fog or snowstorm.—One double sentry for each bay, exclusive of bombers and machine gunners.
Sentries will invariably be posted and relieved by a N. C. O. under the orders of the platoon commander.
It must be recognized that no fixed rules can be laid down as regards the number of sentries that are necessary and battalion commanders will use their discretion in the matter. The number required will depend on the proximity of the enemy, the tactical situation, and, above all, on the state of our own wire entanglements.
3. OFFICER AND N. C. Os. OF THE "WATCH."—In every company in the firing line the company commander will arrange for his officers to take it in turns to be on "watch" throughout the twenty-four hours.
