Its most striking feature is the large number of cartridges that the magazine. Fig. 12.—Schmidt magazine riHe. contains, viz., 12. Accommodation is found for this large number, without the use of an un-wieldy magazine by making them lie alternately right and left. In other words, the widthof the magazine is about l| time the diameter of a cartridge, and consequently it will admita very considerable number without being of any great depth. The magazine is filled frompackets of cartridges, each containing six ; it therefore requires the contents of two packetsto replenish it when empty. It can, however, be supplied with cartridges one at a time, likethe Lee-Speed. By means of a cut-off the magazine can be put out of action, and thepiece used as a single-loader. Under these conditions the reserve remains untouched untilthe supreme moment of the attack, when a rapid stream of bullets can be poured out. Shouldthe contents of the magazine not be sufficient, a fresh supply can be inserted in 8 sec. Themotion for operating the breech-action is entirely rectilinear, as
