Seventeen men are a proper number for working a IX-in. gun under any circumstances. Rammer handles are to be marked for place of charge and of shell. Side and train tackles are also to be marked to the proper overhaul, so as to avoid slack rope. Breast-sweeps are useful at lower sill of port, for training more than a point. X. "SECURE!" 229. The Powder-boy returns the spare powder and the passing-boxes to the magazine. The Shellmen return the shells and empty shell-boxes, if any remain on deck, to the shell-room. The Gun Captain directs the gun to be laid square in the middle of the port. When the guns are to be secured without being housed the Loader and Sponger place the chocking-quoins square up against the rear part of the front trucks and put in the tompion. The Handspikemen, if there is a quoin, free the quoin and lower the breech, the 2d Captain handling the quoin. When the gun is fitted with an elevating screw this operation is performed by the 2d Captain alone, who handles the screw. The Gun Captain, assisted by the 2d Captain, hauls the breeching through the jaws of the cascabel to the left side of the gun, forming with the bight a turn over the breech and cylinder, taking care to keep the breeching well clear of the elevating screw to prevent chafe, and securing the parts on each side with selvagees and heavers; or, if this should interfere with the breech-sight, by crossing the breeching at the side and securing it with selvagee straps and toggles. In this case the breeching should be secured after alternate exercises right and left. The Loader and Sponger haul up and secure the lower half-ports, put in tompion, and secure muzzle-bag. The Gun Captain puts in the vent-plug, lays the hammer of the lock in its place, and the lock-string in a coil around it. The 2d Captain takes the lock-cover from the Train-tackleman and secures it over the lock, and in like manner covers the breech and reinforce sights. The men at the side-tackles unhook the outer blocks from the training-bolts and hand them to the Loader and Sponger, who hook them to the securing-bolts at the sides of the port. The men on both sides haul them taut and stop the parts of the tackles together, with knittles provided by the Quarter Gunner, and then expend the remainder of the falls by passing them around the breech of the gun, through the jaws of the cascabel, and stopping the bights alternately to the eye-bolts on each side of the port until expended; or, at four-truck carriages, take two half hitches over the tail of the brackets, and expend the ends of the falls. The Train-tackle men hook the train-tackle to the side-tackle bolts on each side of the port, the double block on the left side, haul the tackle taut, expend the end round the breech, and stop the parts in with the side-tackles.[8]
