"That's my name," affirmed the other, as he unwound the towel from about his head, and looked at Bart with a pair of very red eyes. "You look as if you saw a ghost."

"Well, I couldn't be more surprised if I saw a whole regiment of ghosts. Is it really you—alive?"

"To be sure."

"But—but—didn't you go over Black Bluff?"

"Yes."

"Then how do you happen to be here? It can't be you fell all the way down into the water, and then swam out?"

"No."

"Then what did happen? For mercy sake, tell me, and relieve me of this suspense."

"Why, I didn't fall far—not more than ten feet. I struck on a shelf, and lay there stunned."
