"Crazy!" cried Archie.

"Right!" said Billy.

"We've got it!" Archie exulted. "'Doctor, come quick. Pop's gone crazy. I'm afeared.' That's the message. What shall we do?"

"We can't do anything now."

"How's the ice on the Arm, Billy?"

"Movin' out. A man couldn't cross now. I barely made it."

"Will the Arm be free in the morning?"

"No; it will not. The Arm will be fit for neither foot nor punt in the morning. T' get t' Poor Luck Barrens a man would have t' skirt the Arm t' Rattle Water an' cross the stream."

"We'll have to do something, Billy. We can't leave that poor girl alone with a madman."
