2. The mechanism of the deployments, the advance by rushes even after the line is mixed, control of fire, and all these directed by signals only; verbal commands should not be used. 3. Estimating distance must be taught. 4. Pointing and aiming drill and gallery practice, so that the man will always bring his piece up properly, look through the sights and pull the trigger only after careful aim, must be practiced until the necessary habit is formed. 5. There must be frequent close order drill. Knowledge of this is necessary for the orderly movement of troops and it is our greatest aid to discipline. But to be an aid to discipline it must be exact, otherwise it has a reverse effect. It is just as easy to do it correctly as to do it approximately if you only teach it so at the beginning and then give the subject attention ever afterward and do not allow the drill to become sloppy. 6. The use of the bayonet must be taught and practiced. 7. The men must be taught simple intrenching and the various uses of sand bags. 8. First aid and personal hygiene. 9. Patrolling; especially the combat patrols and those with advance and rear guards and outposts. As many as possible should know how to read a map. 10. The company musicians and two or three privates should know the flag signalling. But the captain may say: all these are practicable with the regulars who have all the time needed and daylight in which to work and ground to work on; but how are we to do these in an armory at night? [Sidenote: Required equipment] Every armory should have a place fixed for gallery practice if it is only a backing for the target against the wall in one of the corners. And no company should be without a sand table; a relief map is also very desirable. With this equipment let us see what we can do. The ordinary drills of course are on the armory door. [Sidenote: Estimating distances] The principles of estimating distance should be taught the company and the men urged to practice it for themselves. Groups are formed and go anywhere it is convenient for this purpose. Occasionally, if found practicable, the company goes out. Officers and non-commissioned officers in this same way should learn to use the range finder. [Sidenote: Patrolling] Patrolling can be well taught on the sand table or relief map. Pile up your sand, forming any desired terrain; with yellow strings mark the roads and with blue ones the streams, little bridges, etc., can be made with a jackknife, houses represented by blocks, forests with little pieces of evergreen—you have your outdoors. A scale must be provided and one end of the table marked as north.
