Then they all cheered. The crew on board the wreck were steadily drawing the rope through the water. Charlie looked intently with both eyes, and he wished that his ears also could be eyes for a little while.

“Come here!” shouted John to Charlie, and he led the boy around to a coil of rope, one end of which was attached to the line going through the water.

“See there, Bub! There is a block, what they call a single pulley-block, and this stouter rope is doubled through it. It will soon go to the wreck.”

Another explanation was then bawled at Charlie, who now wished his eyes were ears, so anxious was he to hear.

“Look at that block, and then there is what they call a tally-board, and it has some printed directions on it, telling the men on the wreck just what to do. Only watch!” he shouted.

The stouter rope had now started on its journey through the waters, and was taken on board the wreck.

“There,” said John, “you noticed the rope was doubled through that block?”

Charlie nodded assent.

“That gives us what we call an endless line—line. O, those noisy waves! The line runs through the block, I told you, which must have got to the wreck by this time. Here, you see, one end is made fast. At the wreck the tally-board told them just where to hitch it. Now watch! They are hitching on to the line a bigger one yet, and that will be hauled out to the schooner, and fastened above the other line. A second tally-board tells them what to do.”

Here John stopped to lay in a fresh stock of breath. Charlie saw that two of the men on shore had been rigging tackles to long supports planted firmly in the sand.
