Frank held the match. They had to be careful, for the place was as dry as tinder and any negligence might have made the whole place a mass of flame from which there would have been no escape. In the glow, then, Joe searched frantically, casting the old pails and the old bits of board and lumber aside with reckless abandon.

One entire side of the tower top was searched without result. Then, on the far side, they spied a number of boards piled up in a peculiar manner. They did not look as though they had been flung there carelessly or accidentally, but rather as though they had been placed to hide something.

Like a terrier after a bone, Joe made for it. Frantically, he tore away the boards.

There, in a neat little hiding place formed by the wood, lay a bag. It was an ordinary gunny sack, but when Joe dragged it forth he knew at once that their search had ended.

“We’ve found it!” he exulted.
