(2) THE TWO-ARM SEMAPHORE CODE.

(See illustrations in chapter XII.)

SECTION 4.  SCHOOL OF THE SOLDIER.

48.  The instructor explains briefly each movement, first executing it himself if practicable.  He requires the recruits to take the proper positions unassisted and does not touch them for the purpose of correcting them, except when they are unable to correct themselves.  He avoids keeping them too long at the same movement, although each should be understood before passing to another.  He exacts by degrees the desired precision and uniformity.

49.  In order that all may advance as rapidly as their abilities permit, the recruits are grouped according to proficiency as instruction progresses.  Those who lack aptitude and quickness are separated from the others and placed under experienced drill masters.

INSTRUCTION WITHOUT ARMS.

50.  For preliminary instruction a number of recruits, usually not exceeding three or four, are formed as a squad in single rank.
