It was almost nightfall when the snow stopped coming down, and then it was too dark to attempt the journey to Bear Pond.
"We'll have to make another night of it here," said John Barrow. "Then, if it's clear, we can start for the pond early in the morning."
"Hark!" cried Tom, rousing up. "Did you hear that?"
"Hear what?" came from the others.
"I thought I heard somebody calling."
All listened. For a few seconds silence reigned, then came an uncertain sound from a considerable distance.
"There it is!"
"That's somebody calling, sure," said the guide. "Must be down along the river. I'll go out an' look."
"Can I go along?" asked Dick. "You may want help—if somebody is in trouble."
"All right. Bring your gun with you."
