"Don't knock any stones on us!" came back from Stanley. He and Spud had braced themselves on the sides of the old well, with the water up to their waists.

"We'll be as careful as we can," answered Songbird.

"Look out for dirt in your eyes," added Tom. All the fun had died out of him and his face was full of concern.

Slowly and cautiously the three boys lowered the sapling into the old well hole. In doing this they had to stand close to the edge, and once they sent down a shower of loose dirt that caused a wild cry of alarm from below.

"Go slow!" cried Spud, presently. "I've got it," he added, a second later. "Let her come," and then the sapling was lowered until the roots rested on the bottom of the hole. The top was now several feet below the top of the old well.

"The old chain—just the thing!" cried Sam, and took it up.

"You had better come up close together," suggested Songbird, peering down at those below. "Then, if the well caves in, you'll be up that far anyway."

This was thought good advice and Stanley and Spud determined to act on it. Stanley came first with Spud at his heels. The many small branches of the sapling afforded good holds, and as each of the youths was something of an athlete, both of them came up with comparative ease.

"Can't get any higher," remarked Stanley, when within two feet of the top of the sapling. "It's almost ready to break now."

"Catch hold of the chain!" cried Sam. "I'll hold it. Tom and Songbird, you hold me, so I don't fall in."
