each understands and correctly transmits such order in detail
to his successor.

119. There should be at least one noncommissioned officer constantly
on the alert at the guardhouse, usually the corporal whose relief
is on post. This noncommissioned officer takes post near the
entrance of the guardhouse, and does not fall in with the guard
when it is formed. He will have his rifle constantly with him.

120. Whenever it becomes necessary for the corporal to leave
his post near the entrance of the guardhouse, he will notify
the sergeant of the guard, who will at once take his place, or
designate another noncommissioned officer to do so.

121. He will see that no person enters the guardhouse or guard
tent, or crosses the posts of the sentinels there posted without
proper authority.

122. Should any sentinel call for the corporal of the guard,
the corporal will, in every case, at once and quickly proceed to
such sentinel. He will notify the sergeant of the guard before

the necessity for his relief ceases.

posted at the guardhouse.

and post it at the proper hour.

128. Should the guard be turned out, each corporal will call his
own relief, and cause its members to fall in promptly.

129. Tents or bunks in the same vicinity will be designated for the
reliefs so that all the members of each relief may, if necessary,
