The buffer-liquid,on recoil, has to pass through holes in the piston. The access of thebuffer-liquid to these holes is controlled by a disk valve rotated byrifled grooves in the cylinder. By connecting the piston-rod to thecarriage so as to rotate the piston when the gun is elevated, thearea of the holes exposed by the disk valve can be decreased at highelevations so as to shorten the recoil. This is known as the Vavasseur

This is known as the Vavasseur-Ehrhardt control valve. Messrs Cockerill use a channel throughwhich the liquid is forced on recoil, which is partly closed by a stop-cock connected to the left trunnion when the howitzer is running-up springs require to be strong in order to lift theweight of the howitzer at 45° elevation In most equipments twincolumns of springs are used. The Ehrhardl Field Howitzer, fig. 67 (Plate IV.), may be takenas a type of the light field howitzer with controlled recoil, as opposed. Fig. 66.—Wagon Body, Rumanian (Krupp) Quick-firing Field Gun to the Krupp pattern with rear trunnions and constant long howitzer is represented immediately after firing, before it hasrun up. The recoil is automatically shortened so that when fired atthis high elevation the buffer, which is seen under the breech, doesnot strike the ground. The sights are on the bar which passes throughthe shield. The calibre is 47 in.: the howitzer fires a 46 tb shellwith 985 , and weighs 25 cwt. in action with shield. The Mountain Gun.—A mountain gun has the same tacticalduties to fulfil as a field gun. It is merely a field gun sufficientlymobile for mountain transport. Its weight and dimensions arerestricted by the following considerations: (l) The whole equip-ment has to be carried on pack animals. (2) The average load fora battery mule is about 280 lb, including 65 lb of sa
