1. The tendency is to make the trench too narrow; hence, guard against this.

2. Be careful not to throw the earth too far or too near.

3. Do not strike your neighbor's tools in working.

4. Do not use the pick unless necessary, because it makes considerable noise.

5. Do not scrape the tools together in order to get off the dirt; use a chip of wood or the toe of the shoe.

6. Make as little noise as possible in digging and handling your tools.

7. If discovered by the enemy's searchlights, do not become excited or confused; simply lie down.

8. If attacked by the enemy, do not get rattled and throw your tools away—put them in some fixed place where they can be found again.

[1100]. Equipment. At first the men should be taken out without arms, but later on they should be trained to work in full equipment. Teach every man what parts of his equipment are likely to make a noise under special circumstances, such as lying down, rising, crossing obstacles, etc., and instruct him how to guard against it. Bayonets should always be fixed, but in order to avoid accidents the scabbard should be left on them.

From the beginning of the training continually impress upon the men that it is absolutely criminal to fire without orders during a night operation and that the bayonet is the only weapon he can use with advantage to himself and safety to his comrades.
