The non-commissioned officer and one member of the guard will go for meals at the proper hour; upon their return the other members will be directed to go by the non-commissioned officer. (With park and stable guard the guard will be so sent to meals as to leave at the guard-house one non-commissioned officer and one private, exclusive of sentinels on post.) Smoking in stables or their immediate vicinity is prohibited. No fire or light other than the stable lanterns will be permitted in the stables. Stable-guard duty in the field will be performed upon the same principles, with the modifications rendered necessary by the changed conditions. =Duties of the Battery Officer of the Day.=--He has supervision of the guard, attends all stable duties and such drills and battery roll-calls as may be designated as requiring his presence. He should inspect the guard and sentinels during the day and night as often as he may deem necessary. After the new battery officer has visited the guard at guard-mounting and seen that the orders have been correctly turned over, he will report to the battery commander for instructions. =Commander of the Guard.=--The senior non-commissioned officer of the guard is commander of the guard. The commander of the guard is responsible for the instruction and discipline of the guard. He will see that all its members are correctly instructed in their orders and duties, and that they understand and properly perform them. He receives and obeys the orders of the battery commander and the battery officer of the day, and reports to the last named without delay all orders relating to the guard not given or transmitted by him. He transmits to his successor all material instructions and information relating to his duties. He is responsible for the general safety of the camp as soon as the old guard marches from the guard-house. In case of any emergency occurring while both guards are at the guard-house, the senior commander of the two guards will be responsible that proper action is taken. A commander of a guard leaving his post for any purpose will mention his destination and the probable duration of his absence to the next in command. Should it become necessary during the absence of the commander of the guard for the next in command to leave the guard, he will designate a member of the guard to take charge and assume the responsibility during his absence. The member so designated will be obeyed and respected accordingly, and will be held responsible for the proper performance of his duties. All prisoners will be thoroughly searched before being allowed to enter the guard-house. The prisoners will be marched under proper guard to the mess-hall for their meals; they must be sent to their meals at times when the other men of the battery are not present, and will be allowed the same time as other members of the guard.
