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.

rifle or pistol, or dismounted sentinels armed with a pistol, after
challenging. (See Par. 1742.) (174)

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.

=1738.= The salute is rendered at 6 paces; if the person to be saluted
