"There trail," he announced, pointing a long, bronzed finger at the
edge of the water.

Tad stooped over, examining the shore critically.

"The Shawnee is right," he said, turning to the Professor.

"How do you know? What have you found?"

"There. You can see for yourself. It is distinctly marked--"

"What's marked?" demanded Stacy, pressing forward.

"You can see where the keel of a canoe has rested in the dirt there.
The trail is ever so faint, but it is unmistakably there. See how it
broadens out as it extends backward until it reaches the gravel in the
stream."

"Moccasin tracks," grunted the guide.

"Where?" asked Walter, apprehensively.

"There," answered the Indian, pointing up the bank whence they had
just come.

The boys looked at each other in wondering silence.

"What do you think is the meaning of the visit, Eagle-eye?" asked the
Professor.
