All persons arrested by corporals of the
guard or by sentinels will at once be conducted to the commander
of the guard by the corporal.

SECTION 7. MUSICIANS OF THE GUARD.

138. The musicians of the guard will sound calls as prescribed
by the commanding officer.

139. Should the guard be turned out for national or regimental
colors or standards, uncased, the field music of the guard will,
when the guard present arms, sound, "To the color" or "To the
standard"; or, if for any person entitled thereto, the march,
flourishes, or ruffles, prescribed in paragraphs 375, 376, and
377, A. R.

SECTION 8. ORDERLIES AND COLOR SENTINELS.

140. When so directed by the commanding officer, the officer
who inspects the guard at guard mounting will select from the
members of the new guard an orderly for the commanding officer
and such number of other orderlies and color sentinels as may
be required.

141. For these positions the soldiers will be chosen who are
most correct in the performance of duty and in military bearing,
neatest in person and clothing, and whose arms and accouterments
are in the best condition. Clothing, arms, and equipments must
conform to regulations. If there is any doubt as to the relative
qualifications of two or more soldiers, the inspecting officer
will cause them to fall out at the guardhouse and to form in
line in single rank. He will then, by testing them in drill
regulations, select the most proficient. The commander of the
guard will be notified of the selection.

142. When directed by the commander of the guard to fall out
and report an orderly will give his name, company, and regiment
to the sergeant of the guard, and, leaving his rifle in the arm
rack in his company quarters, will proceed at once to the officer
to whom he is assigned, reporting: "Sir, Private ----, Company
----, reports all orderly."

143. If the orderly selected be a cavalryman, he will leave his
rifle in the arm rack of his troop quarters, and report with
his belt on, but without side arms unless specially otherwise
ordered.

144. Orderlies, while on duty as such, are subject only to the
orders of the commanding officer and of the officers to whom
they are ordered to report.

145. When an orderly is ordered to carry a message, he will be
careful to deliver it exactly as it was given to him.

146. His tour of duty ends when he is relieved by the orderly
selected from the guard relieving his own.

147. Orderlies
