"Perhaps he's deaf," suggested Whopper.

"More likely he doesn't want to show himself."

"Maybe it's a she, Shep."

"Possibly. If it's a woman she must be a regular witch. Let us call again."

They did so. At first they heard nothing in return. Then came a strange sound from the cabin, and for one brief instant a dark, impish face showed itself at the broken window. Then the face disappeared and a stone came whizzing toward the lads' heads. They ducked just in time, or one or the other might have been seriously hurt.

"Let's get out—-no use of staying here to be a target!" cried Whopper, who was growing nervous. "No telling what that fellow—-or woman—-may do next. Might come for us with a carving knife!" And he hurried away, with the doctor's son beside him. They did not slacken their pace until the dilapidated cabin had disappeared from view.

"Did you see him—-or her?" asked Shep.

"Just about and no more. What a dried-up, hateful face!"

"Just what I thought. I'll wager that that person, whoever he or she is, is as mad as a—-a crazy person can be."

"I believe you, and I don't know as I want to go near that cabin again."
