The split trail permits a 45 traverse and a range elevation of 400. To combat aeroplanes the gun can be elevated still further (70). The independent line of sight is used. Elevation corresponding to the angle of site is given to the rocker either by the panoramic sight or by an angle of site index. Elevation corresponding to the range isgiven to the gun and cradle directly by bringing the range of the range scale opposite the index. In direct laying, gunner lays for direction and site, and No. 1 for range only. In indirect laying, gunner lays for direction only and No. 1 lays for site and range. The panoramic sight need be corrected for difference of level of wheels for the first shot only. To insure stability when on uneven ground, _ the flasks are connected to the axle and pintle by means of a universal joint permitting one flask to be raised 18 above the other. There is no sight shank to move. The breech is opened automatically and the empty cartridge case ejected on counter recoil. A spring then trips the block and closes the breech when the projectile is inserted. Recent Improvements in our Service Artillery Material. By Maj. E. P. O'Hearn, O.D. Field Artillery Jour.

The howitzer has a variable recoil; total traverse is 45, the same as the 3-in. gun, M-13. Eight batteries of 3.8-in. howitzers ...
