"He does suspect, at least, how that avalanche started; but he refuses to give me his confidence."

"But Harry hadn't admitted it before. I put it to him straight if he and Joe left that canoe and came over here during the night."

"Well?"

"Swore he didn't leave the canoe," said Pence, anxiety betrayed in his voice. "Harry's more than ordinarily truthful—so I've always found him. Don't you suppose that the bowlder might have been washed out by the rain, after all?"

"The rain wouldn't have washed the lever out of the woods and down the hill into the field behind the place where the bowlder lay."

"Hardly!" agreed Pence, startled by this reasoning.

"Kirby says he didn't leave the canoe all night?"
