No. 1: =To take charge of this post and all Government property in view.= =157.= All persons, of whatever rank in the service, are required to observe respect toward sentinels and members of the guard when such are in the performance of their duties. =158.= A sentinel will at once report to the corporal of the guard every unusual or suspicious occurrence noted. =159.= He will arrest suspicious persons prowling about the post or camp at any time, all parties to a disorder occurring on or near his post, and all, except authorized persons, who attempt to enter the camp at night, and will turn over to the corporal of the guard all persons arrested. =160.= The number, limits, and extent of his post will invariably constitute part of the special orders of a sentinel on post. The limits of his post should be so defined as to include every place to which he is required to go in the performance of his duties. No. 2: =To walk my post in a military manner, keeping always on the alert and observing everything that takes place within sight or hearing.= =161.= A sentinel is not required to halt and change the position of his rifle on arriving at the end of his post, nor to execute =to the rear, march=, precisely as prescribed in the drill regulations, but faces about while walking in the manner most convenient to him and at any part of his post as may be best suited to the proper performance of his duties. He carries his rifle on either shoulder, and in wet or severe weather, when not in a sentry box, may carry it at a secure. =162.= Sentinels when in sentry boxes stand at ease. Sentry boxes will be used in wet weather only, or at other times when specially authorized by the commanding officer. =163.= In very hot weather, sentinels may be authorized to stand at ease on their posts, provided they can effectively discharge their duties in this position; but they will take advantage of this privilege only on the express authority of the officer of the day or the commander of the guard. 164. A mounted sentinel may dismount occasionally and lead the horse, but will not relax his vigilance. No. 3: =To report all violations of orders I am instructed to enforce.=
