No. 7: To talk to no one except in line of duty. (171)
[1733]. When calling for any purpose, challenging, or holding communication with any person, a dismounted sentinel, armed with a rifle or saber, will take the position of "port" arms or saber. At night a dismounted sentinel, armed with a pistol, takes the position of raise pistol in challenging or holding communication. A mounted sentinel does not ordinarily draw his weapon in the daytime when challenging or holding conversation; but if drawn, he holds it at advance rifle, raise pistol, or port saber, according as he is armed with a rifle, pistol, or saber. At night, in challenging and holding conversation, his weapon is drawn and held as just prescribed, depending on whether he is armed with a rifle, pistol, or saber.
No. 8: In case of fire or disorder to give the alarm. (172)
[1734]. In case of fire, a sentinel will call, "Fire No. (—)," adding the number of his post; if possible, he will extinguish the fire himself. In case of disorder, he will call: "The Guard, No. (—)," adding the number of his post. If the danger be great, he will, in either case, discharge his piece before calling.
No. 11: To salute all officers and all colors and standards not cased. (173)
[1735]. When not engaged in the performance of a specific duty, the proper execution of which would prevent it, a member of the guard will salute all officers who pass him. This rule applies at all hours of the day or night, except in the case of mounted sentinels armed with a rifle or pistol, or dismounted sentinels armed with a pistol, after challenging. (See [Par. 1742].) (174)
[1736]. Sentinels will salute as follows: A dismounted sentinel armed with a rifle or saber, salutes by presenting arms; if otherwise armed, he salutes with the right hand.
A mounted sentinel, if armed with a saber and the saber be drawn, salutes by presenting saber; otherwise he salutes in all cases with the right hand. (175)
[1737]. To salute, a dismounted sentinel, with piece at a right shoulder or saber at a carry, halts and faces toward the person to be saluted when the latter arrives within thirty paces.
The limit within which individuals and insignia of rank can be readily recognized is assumed to be about 30 paces, and, therefore, at this distance cognizance is taken of the person or party to be saluted. (176)
