which deadens the return shock. The air recuperator is
independent of the recoil cylinder, and is formed of an
outside cylinder in one piece with the cradle, and one
containing an inside piston, the rod of which is jointed
to the shoulder-piece already referred to. When firing
takes place, the compressée! air which is in the inside
cylinder, and in the space between the two cylinders, is
forced into the latter space ; as soon as recoil is spent a
reaction of the air takes place, and the piston works
forward. The carriage is in two parts, the carriage proper
which gears in a curved rack fixed under the cradle on the
centre line of the carriage.
The wheels and axle are designed for a track of
800 millimétrés (31.496 in.) on the tread ; the wheels are
700 millimétrés (27.559 in.) in diameter, the nave is
of brass, and the rim of bent wood, in three pieces.
The spokes are joined to the rim by means of steel
sockets.
The sighting device contains a scale fitted to the cradle:

steel plates, joined together by top and bottom trail-plates
and by stay-plates. The two parts are quickly joined
together by means of damps and pins. The end of the
trail is fitted with a rigid spade, similar to that of quick-
firing field guns. The nose-plate is arrangée! for booking
on the fore-limber, by means of a pivot-bolt of the usual
shape, or for direct hauling, two rings being also provided
for holding the shaft.
The elevating mechanism is set in motion by a crank
placed on the left side of the carriage ; it works a pinion
is arranged for laying the gun direct from 0 deg. to
60 deg.
For transport on mules, the piece is divided as follows :

hooked on a fore-limber. The latter is on two wheels,
