Use SHOT at masses of troops, and to batter, from 600 up to 2,000 yards. Use SHELL for firing buildings, at troops posted in woods, in pursuit, and to produce a moral rather than a physical effect: greatest effective range 1,500. Use SPHERICAL CASE SHOT at masses of troops, at not less than 500 yards; generally up to 1,500 yards. CANISTER is not effective at 600 yards; it should not be used beyond 500 yards, and but very seldom and over the most favorable ground at that distance; at short ranges, (less than 200 yards.) in emergency, use double canister, with single charge. Do not employ RICOCHET at less distance than 1,000 to 1,100 yards.

CARE OF AMMUNITION CHEST 1st. Keep everything out that does not belong in them, except a bunch of cord or wire for breakage; beware of loose tacks, nails, bolts, or straps. 2nd Keep friction primers in their papers, tied up. The pouch containing those for instant service must be closed, and so placed as to be secure. Take every precaution do not get loose; a single one may cause an explosion. Use plenty of tow in packing. (This sheet is to be glued on the inside of the Limber Chest Cover.)
