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?
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.
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.
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.
