A hook is fixed on each part of the whip, near the block, so that the parts being bowsed on alternately, a full box is brought up on one hook and an empty one lowered by the other, at the same time.
FLASH-PANS.

DARK LANTERNS.
220. To be made of copper, tinned inside, with two handles at the side, that the shade may be turned without taking hold of the top. The whole height, 12 inches; diameter, 4 inches.
BOAT GRAPNELS.
221. Are made of round iron, quite light, for throwing into the rigging or chains of the enemy, for the purpose of holding on when boarding; their prongs are barbed.
Six feet of small chain are to be attached to the ring, and connected with six fathoms of one and three quarter rope.
TARGETS.
222. In the construction of targets for practice at sea, the chief object will be to give buoyancy and stability to the screen, with sufficient development of its surface. To these ends, whiskey or beef barrels, supporting boards of sufficient length, will afford staging for the masts, yards, and screen; the heel of the mast passing through the stage, and having ballast attached to it. The stage should be so fitted as to be readily put together when wanted, and taken apart for stowage.
