Cylindrical tin cases with iron heads, of calibre suitable for different pieces of ordnance, filled with cast-iron balls arranged in tiers; they are fired at ranges not exceeding 400 yards, but their most destructive effects are from 100 to 200 yards.
6. What are grape shot?
A certain number of iron balls, usually nine, put together by means of two cast-iron plates, two rings, and one pin and nut. Each plate has on the inside three beds for the shot, of a depth equal to half the thickness of the plate, and of the form of a spherical segment, the curvature of which is the same as that of the shot. An iron pin riveted to the bottom iron plate, passes through the centre and also through the top plate, where the whole is secured by a nut and screw.
Note.—The use of these shot for field pieces has been discontinued, canister answering the purpose of these shot.
7. How were the balls fixed in the old pattern?
They were placed in tiers around an iron pin attached to an iron tompion at the bottom, and put into a canvas bag, and then quilted around with a strong cord.
8. What is a grenade?
A shell thrown from the hand, or in baskets from the stone-mortar, and ignited as other shells by means of a fuze.
9. How many kinds of grenades are made use of?
Hand-grenades and rampart-grenades; six-pounder spherical case may be used for the former, and shells of any calibre for the latter.
