"Can't you trail them?" asked Stacy.
The Shawnee shook his head.
"Why not?"
"No leave trail. Smart man."
"Yes, there is no doubt of that," agreed the Professor. "Have you any idea who did this thing, Eagle-eye?"
The Shawnee shrugged his shoulders as indicating that he did not know.
"Probably it was the same fellow whom you found fooling about the camp the other night," suggested Walter.
"Just what I was thinking," added Ned.
"Yes, no doubt he is the man. But what we are going to do, I don't know. It occurs to me that I might send some one on to Mr. Munson, superintendent of the Red Star Mine, to whom I have a letter, asking him to send us on a couple of extra ponies."
"Does he know who we are?" asked Walter Perkins.
