"I'm going down after that!" he said in a moment.

"Yes, you are!" whispered Tommy.

"I got to have it!" insisted Will.

"I don't think he cut the rungs between this level and the next one,"
George interposed. "It may be safe to use the lower ladders."

"I can soon find out!" Will declared.

The cutting had been done between the second level and the top. The ladders below seemed perfectly safe. After testing them thoroughly, Will trusted himself on one of the rungs and let himself down slowly, bearing as much weight as was possible on the standards.

He was at the bottom in a moment, and in another moment stood by the side of his chums with the saw in his hand.

"I don't think that's so very much!" Tommy exclaimed.

"Right here, then," Will explained, "is where you get your little Sherlock Holmes lesson! This is a new saw, as you all see. It probably never was used before. Now the man who did the cutting bought this at some nearby store. Don't you see what it means?"
