Fred Greenwood was not there, nor did the cavern show signs of having been visited by person or animal.
But hold! When Hank threw down the last expiring match, he caught a glimpse of something white on the flinty floor.

He had not thought of looking for anything, and it was the accidental following of the match with his gaze that revealed the object.

Instantly another match was sending out its feeble rays, and he stooped down and picked up that which had arrested his attention.
It was a piece of paper, apparently the blank leaf of a letter.

There was no writing or mark on it to indicate its ownership, but had it been the visiting-card of Fred Greenwood, Hank Hazletine could not have been more positive that it belonged to the young man.
It was impossible that Motoza should carry writing-paper with him.

The cowman never did so, consequently he could not have dropped it on his late visit.
