selvagees

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.
