Siege and Sea-coast Ammunition

—On account of the great weight of siege and sea-coast ammunition, the cartridge-bag and projectile are carried separately. The cartridge-bags for large charges of powder are made of two pieces of woolen stuff, or of a paper tube with a woolen cloth bottom. The former are preferred for rapid firing. For sea-coast howitzers the bag should fill the chamber; if the piece be fired with a reduced charge, a cartridge-block should be inserted into the bag to give it proper size. For mortars the bag is only used to carry the powder, and when the piece is loaded, the powder is poured into the chamber; bags of any suitable size will answer for this service. For hot-shot cartridges bags are made double, by putting one bag within another. Care should be taken to see that the bags are free from holes. For ricochet firing, or other occasions when very small charges are required, a cartridge-bag of inferior caliber may be used. In the siege and sea-coast services, solid shot are transported and loaded loosely, but hollow projectiles are strapped to sabots, to prevent the fuze from coming in contact with the powder of the charge. The sabots are made from thick plank, and the straps are fastened as in the field service.
