MANUAL FOR NONCOMMISSIONED OFFICERS. 257 



16. There will be an officer of the day with each guard, unless 

 in the opinion of the commanding officer the guard is so small 

 that his services are not needed. In this case an officer will 

 be detailed to supervise the command and instruction of the 

 guard .for such period as the commanding officer maj^ direct. 



17. When more than one guard is required for a command, 

 a field officer of the day will l)e detailed, who will receive his 

 orders from the brigade or division commander, as the latter 

 may direct. When necessary captains may be placed on the 

 roster for field officer of the day. 



18. The detail of officers of the guard will be limited to the 

 necessities of the service and efticient instruction ; inexperi- 

 enced officers may be detailed as supernumerary officers of the 

 guard for purposes of instruction. 



19. Officers serving on staff departments are, in the discre- 

 tion of the commanding offi-cer, exempt from guard duty. 



20. Guard details will, if practicable, be posted or ])ui3lished 

 the day preceding the beginning, of the tour and oflicers noti- 

 fied personally by a written order at the same time. 



21. The strength of guards and the number of consecutive 

 days for which an organization furnishes the guard will be so 

 regulated as to insure privates of the main guard an interval 

 of not less than five days between tours. 



When this is not otherwise practicable, extra and' special 

 duty men will be detailed for night guard duty, still perform- 

 ing their daily duties. When so detailed a roster will be kept 

 by the adjutant showing the duty performed by them. 



22. The members of main guards and stable and park guards 

 will habitually be relieved every 24 hours. The length of 

 the tour of enlisted men detailed as special guards, other than 

 stable or park guards, will be so regulated as to permit of 

 these men being held accountable for a strict performance of 

 their duty. 



23. Should the officer of the day be notified that men are re- 

 quired to fill vacancies in the guard, he will cause them to be 

 supplied from the organization to which the guard l)oIongs. 

 If none are available in that organization, the adjutant will 

 be notified and will cause them to be supplied from the organ- 

 ization that is' next for guard. (Par. 63.)
