feet or so by this obstacle.

Supposing that the creature which had passed here had clambered over the
log, Tom's scouting instinct was aroused to examine the rough bark
carefully for any little tuft of hair which the animal might have left.
And not finding any, he was puzzled. For by its tracks the creature must
have been very small, certainly too small to have stepped, and not at
all likely to have jumped over the log. If then it had clambered over
the log it seemed remarkable that it had left no trace, not even a
single hair, upon that rough surface.

Tom knew that this was unusual. He knew that old Uncle Jeb would laugh
at him if he went back and said that some small creature had crawled
over that nutmeg grater and left no sign of its crossing. He knew that
no animal could graze a tree in its flight but old Uncle Jeb would find
there some tell-tale souvenir of its passing.

Tom's interest was keenly aroused now. He was baffled and a little
chagrined. But no supplementary inspection revealed so much as a single
hair.

Thus confounded, he examined the tracks more carefully. He followed them
up to where they emerged from the lower reaches of the mountain. Then he
followed them back, aided where they were dim by the deeper prints of
Hervey's shoes. Skinny sat upon the log waiting for him.

On the side of the log nearest the mountain the tracks turned and went
sideways along the log for perhaps a yard to a point where the log was
low and somewhat broken. Here, evidently, was where the animal had
crossed. It must have been a very small animal, Tom thought, to have
