The construction of the carriage is also similar to that of the Revolving Cannon. A traversing apparatus on the gun enables it to be pointed 111 a horizontal direction as well as in elevation, without moving the trail of the carriage, and the balls can thus be distributed over a sector of a circle within its range during the fire, by adjusting the traverse. The gun has no movement during fire, it being of sufficient weight to resist the recoil of each discharge. This gun has many other valuable advantages, its supenor ballistical features making it a very formidable weapon.

Fo r the Mountain Gatling In Table II. 6""" Gatling, and the number of hits • By the effective power of a n arm is understood the compound quantity which is governed by the number of hits on the targe ts, the time of firing, the dista nce the ta rgets a re placed from th e gun , a nd the dimensions of these targets. , the r,tnge a nd the dimensions of the targets, as these are chosen analogically to the circumstances under which the arms to be tested arc subjected in actual service, we have the mea ns of comparing different kinds of arms under the practical conditions they are employed in.
