were various levers, to use in blowing the ship’s siren, and for other purposes as well, though, of course, Henry did not yet know what they were for, any more than he understood that the Franklin metal life-belts, or buoys, that hung at either end of the bridge could be dropped overboard by a single motion of the hand, and that when they struck the water the queer-looking tubes projecting from them would shoot out lights that would burn for a long period, showing persons struggling in the sea which way to swim for safety.
At present Henry was wholly engrossed in the action that was taking place before him. The ship was moving gently through the water. The anchor had been partly heaved up by the little hoisting engine on the forward deck, but in heaving it, the chain had become twisted around one of the movable flukes, so that the stem of the anchor could not be properly heaved in through the hawse hole. A warrant officer in uniform, and a small group of sailors, leaned over the bow rail, trying to release the fouled anchor. A slender rope ladder had been lowered over the side, and on this a sailor was creeping down to the anchor that hung partly in the water, with a small rope in his hand. The rope he cautiously slipped around a fluke, so that the anchor could be tilted up.
