"Strange cries?" echoed the trapper. "What were they like?"

"Oh, awful—I can't describe 'em."

"Wust you ever listened to," observed Tim Sladder. "We heard 'em at our camp, too."

"An' it didn't sound like no animal, or humans, either," added Musgrove.

"Ah, ha! This is interesting."

Yardsley seemed to reflect.

"We heard the beast twice," said Hackett.

"Well, now," continued Yardsley, "kinder think I did hear something like that. Strange critter it must have been—jest wait a second."

He opened a door and walked into an adjoining room. Then the boys heard a peculiar click.

Just as the trapper emerged, with a broad smile on his face, a terrible series of wild, weird screeches, exactly like those they had heard before, filled the cabin.
