"Who are they?"

"A couple of outlaws who turned things upside down in these hills some years ago. But I got them both. They are serving terms up at Concord now. Find anything?"

"No, sir."

The circles were steadily narrowing, though the man and the girl were working slowly and deliberately, really covering the ground by inches, so thorough was their search for clues of the supposed night visitors. No spot of the size of a hand escaped the keen scrutiny of one or the other of them. They could not have answered had they been asked what particular thing they had hoped to find, but in some vague way each felt that a clue to the mystery would be turned up as a result of their search. If a person had stolen into camp under cover of the night, wounding and stampeding the horses, it was probable that footprints or other evidences of his presence had been left behind, a tell-tale clue to the recent visitor. As yet, not a single trace had been found by the searchers. They continued with their work until they finally brought up facing each other in front of the trees to which the broken ends of the halters were still tied.

"I reckon we're beaten."

"Yes. We haven't found a clue of any consequence. Perhaps we have imagined too much, but I do not think so."

"Give me a torch; it's my turn now. Let's see what Crazy Jane can find," said Jane McCarthy. "My grandfather was the champion shamrock hunter of the Emerald Isle, and my Dad says I'm a pocket edition of my grandfather. Just watch me while I show you a few things."
