FOREIGN FIELD-ARTILLERY.

GERMANY.

There is practically only one gun, viz., the 3.46-inch. The horse-artillery gun, carriage, and limber, are all lighter than in the field-artillery. Model 1891 weighs 970 lbs. The weights behind the teams are: H. A. gun, 3996 lbs.; F. A. gun, 4276 lbs.; caisson, 5036 lbs. No cannoneers are carried on the carriages in horse-artillery. Muzzle velocity, 1400 ft.-sec.

The Common Shell weighs 15½ lbs. (bursting-charge, 6 oz.), and splinters into about 170 pieces. A proportion of the shells are filled with wet guncotton, having a dry guncotton primer, to be used, as a rule, against men under cover.

The Shrapnel contains 262 bullets with bursting-charge down the centre, weighs 17.7 lbs., and can be burst up to 3500 yards range. The number of rounds carried per gun in a battery is 135. The percussion-shell has been abandoned, and shrapnel, high explosive shell, and canister only are used. The fuze is a combination time, and percussion-fuze.

There are 20 carriages in a battery—6 guns, 9 caissons, 4 store-wagons, 1 forge-wagon. A battery carries 9 shovels and 2 pickaxes.
