“It would be a great place for a hunter or a trapper to spend the winter,” Mayhew commented, “if only he could get used to the awful things there are going on in this beautiful section of country. You see, the snow must soon melt where there is so much heat; and that keeps the grass green for the deer and the buffalo.”
“Hark!” exclaimed Roger, stopping suddenly.
His face lighted up with eagerness, and Dick was filled with curiosity.
“What did you think you heard?” he asked, presently.
“The signal we want to catch more than anything else,” came the confident reply.
“Not the whistle Jasper Williams taught us to practice, Roger, and which he uses when he wants to communicate with friends?”
“That, and nothing else, Dick. I am sure I caught it, coming from somewhere over to the right.”
“Then why not answer it?” Dick told him.
“Do you think it would be wise?” asked the other.
“We want to know if Jasper Williams is near by, and that is the best way to find it out. You can give the whistle, Roger, for I have heard you practice it many times.”
