PROOF of Foreign Brass-Artillery. 1st, The Prussians. Their battering-train and garrison artillery are proved with a quantity of powder equal to ½ the weight of the shot, and fired 75 rounds as fast as in real service; that is, 2 or 3 rounds in a minute. Their light field-train, from a 12-pounder upwards, are proved with a quantity of powder = 1.3d of the weight of the shot, and fired 150 rounds, at 3 or 4 rounds in a minute. From a 12-pounder downwards, are proved with a quantity of powder = 1.5th of the shot's weight, and fired 300 rounds, at 5 or 6 rounds each minute, properly spunged and loaded. Their mortars are proved with the chambers full of powder, and the shells loaded. Three rounds are fired as quick as possible.
2d, The Dutch prove all their artillery by firing each
each piece 5 times; the two first rounds with a quantity of powder = 2-3ds of the weight of the shot; and the three last rounds with a quantity of powder = the weight of the shot.
3d. The French the same as the Dutch.
