_d._ The horses and equipments of the first sergeant and stable sergeant (unless otherwise ordered by the battery commander) may be taken out by themselves, or on their written order, between reveille and retreat. This privilege may be extended to the other sergeants. _e._ The battery team will be allowed to leave the stables in the daytime (between reveille and retreat) when the wagoner reports it to be necessary. In case of fire at the stable the commander of the guard will take the necessary precautions in opening or closing the doors, so as to prevent as far as possible the spreading of the fire and make it possible to remove the horses. He will then, assisted by all the available men, commence to lead out the horses, and, if practicable, secure them at the picket-line or other designated place. The non-commissioned officer will have exclusive control of the lanterns, and will see that they are prepared during the day for lighting at night. The lanterns will not be lighted, filled, or trimmed in the stables, but must be taken to the guard-room, or to such other place as may be designated by the battery commander for the purpose. The non-commissioned officer must answer the sentinels' calls promptly. =Sentinel of Stable-guard.=--The sentinel in the discharge of his duties will be governed by the regulations for sentinels of other guards whenever they are applicable, such as courtesies to officers, walking post in a soldierly manner, challenging, etc.; he will not turn out the guard except when ordered by the proper authority. The sentinel will receive orders from the battery commander, the battery officer of the day, and the non-commissioned officers of the stable-guard only. The sentinel will not permit any horse or equipments to be taken from the stables except in the presence of the non-commissioned officer. Should a horse get loose, the sentinel will catch him and tie him up. If he be unable to catch the horse, the non-commissioned officer will be at once notified. In case a horse be cast, or in any way entangled, he will relieve him if possible; if unable to relieve him, he will call the non-commissioned officer. Sentinels are forbidden to punish or maltreat a horse. When a horse is taken sick, the sentinel will notify the non-commissioned officer, who will in turn call the stable sergeant, and see that the horse is properly attended to. In case of fire the sentinel will give the alarm by stepping outside the stable and firing his pistol (if he be armed) repeatedly, calling out at the same time, "_Fire, stables, battery--!_" As soon as the guard is alarmed he will take the necessary precautions in opening or closing the doors, so as to prevent the spreading of the fire and make it possible to remove the horses; he will drop the chains and bars, and, with the other members of the guard, proceed to lead out the horses, and secure them at the picket-line or such other place as may have been previously designated.
