Report of the British naval and military operations in Egypt, 1882 . Fig. 165, which receives the axle, istoo light and yields under the shock of the heavyrecoil.

The rear-sight socket, a piece of copper screwedinto the gun, is liable to work loose and affect thepointing, while it is exposed to injury in mount-ing and dismounting. Similarly, the front sight screws into a copper **?E3SK* bouching which frequently moves in its seat. The trunnions being fixed and the breech free to turn about its axis,if sufficiently urged, it is noticed that firing the gun is apt to slackenthe joint, the passage of the shell along the bore tending to unscrewthe breech from the trunnion band. No accident has as yet arisen onthis score, because the guns are carefully watched and the coupling setup afresh whenever necessary. The existence of a leak of gas at thejoint would be shown by its exit through an escape channel drilled inthe center of each 324 The feather marks on the outside of the gun to indicate that the jointis properly made are exact only when the gun leaves the makers practice it is found that each gun requires separate adjustment, sothat it becomes highly necessary for every crew to know its own gun,not only in order to have no leakage of gas, but also to make the allow-ance in sighting occasioned by the rotation of the breech portion awayfrom the normal position in one direction or the other. The vent projects beyond the surface of the gun, as seen in Fig. 153,in order to give the necessary leugth of socket for the friction tube. Great care has been taken that no accident to the vent should arisefrom this peculiarity of construction. It would appear, however, desir-able to devise some other equivalent scheme. The recoil is very heavy, owing to the lightness of the gun and car-riage, but this disadvantage is cascabel hole
