Suddenly her horse stopped. He had come up alongside Bo's horse. Dale had halted ahead, and apparently was listening. Roy and the pack-train were out of sight in the gloom.

"What is it?" whispered Helen.

"Reckon I heard a wolf," replied Dale.

"Was that cry a wolf's?" asked Bo. "I heard. It was wild."

"We're gettin' up close to the foot-hills," said Dale. "Feel how much colder the air is."

"I'm warm now," replied Bo. "I guess being near froze was what ailed me.... Nell, how 're you?"

"I'm warm, too, but--" Helen answered.

"If you had your choice of being here or back home, snug in bed--which would you take?" asked Bo.

"Bo!" exclaimed Helen, aghast.

"Well, I'd choose to be right here on this horse," rejoined Bo.

Dale heard her, for he turned an instant, then slapped his horse and started on.

Helen now rode beside Bo, and for a long time they climbed steadily in silence. Helen knew when that dark hour before dawn had passed, and she welcomed an almost imperceptible lightening in the east. Then the stars paled. Gradually a grayness absorbed all but the larger stars. The great white morning star, wonderful as Helen had never seen it, lost its brilliance and life and seemed to retreat into the dimming blue.
