, are of course added to the apparatus, but are not
indicated in the drawing. The arrangement appears to us to possess
considerable merit, and we shall refer to it again on another occasion,
after experiments have been made to test its efficiency.--_Engineering_.

THE GARDNER MACHINE GUN.
[Illustration: FIG. 1.--SINGLE BARREL GARDNER MACHINE GUN.]
The mechanism by which the various functions of loading, firing, and
extracting are performed is contained in a rectangular gun metal case,
varying in dimensions with the number of barrels in the arm. In the
single barrel gun the size of this case is 14 inches in length, 51/2
inches in depth, and 21/2 inches in width. The top of the box is hinged,
so that easy access can be had to the mechanism, which consists of a
lock, the cartridge carrier, and the devices for actuating them. In the
multiple barrel guns, the frames which, with the transverse bar at the
end, hold the barrels in place, form the sides of the mechanism chamber,
in the front end of which the barrels are screwed.
