=4. "STAND TO."=--"Stand to" will take place 1 hour before daylight and 1 hour before dusk. At this parade every available man will be present. Rifles, ammunition, equipment, clothing, etc., will be inspected. Rapid loading will be practiced. The firing position of every man will be tested, to see whether he can hit the bottom edge of our wire. Gas helmets and respirators will be inspected in accordance with the orders in force. Orders will be issued and steps taken to see that the men understand them. After "stand to" in the morning and before "stand to" in the evening rifles will be thoroughly cleaned and oiled. =5. CARE OF BOMBS AND GRENADES.=--(_a_) Only a small percentage of bombs will be kept in the front trenches. These will be kept in a well-protected and dry bomb receptacle. (_b_) Bomb stores will be built in the end of communication trenches in the support line. (_c_) Detonators and fuzes, except in the front lines, will normally be kept in tins and not in the bomb. (_d_) The battalion grenadier officer will make frequent inspection of all bombs and grenades. (_e_) The alarm posts for grenadiers will be close to where the bomb stores are placed. (_f_) No one, other than a grenadier, will interfere with the bombs and grenades. (_g_) Ammunition boxes in the trenches will be examined frequently to see if the lids work easily. =6. MACHINE GUNS.=--(_a_) The concealment and protection of machine-gun emplacements is important--for this reason, except in case of emergency, machine guns will not be fired from their regular emplacements. (_b_) Unless emplacements are well concealed, guns will not be mounted except between evening and morning "stand to." (_c_) Two men per detachment will always be on duty with the gun. (_d_) Before dusk, while there is still sufficient light, each gun will be laid on some particular spot either in or behind the enemy's front line. (_e_) Range cards will be prepared and kept with each gun. (_f_) _Machine guns in the front line should be reduced to a minimum sufficient to cover the front._ =7. FIRING AT AEROPLANES.=--Firing at aeroplanes will not be permitted except by order of an officer. =8. UNDERCUTTING TRENCH SIDES.=--(_a_) The undercutting of trench sides to make shelters is forbidden. (_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.
