Never in salvoes; but in a regular manner, well sustained, and with distinct intervals between every round, commencing slowly, and increasing in rapidity as the range diminishes.
28. Is the fire of batteries more efficacious when dispersed than when concentrated?
The effects of the fire will be in proportion to the number of guns brought together, and therefore, in order to strike a decisive blow, this should at once be done.
29. What projectiles are used with field guns?
Solid shot, spherical case, and canister.
30. At what distance from the enemy should the several kinds of projectiles be employed with field battery pieces?
Solid shot from 350 yards and upwards; spherical case from 600 up to 1000 yards, although it may be used within the first range; and canister within 350 yards, or up to 400 against extended formations.
31. What number of rounds can be fired from a field gun in one minute?
Two solid shot or spherical case, or three of canister.
