“God help him, if he does. I don’t know what sort of medicine Dr. Brady may have there. There’s vaccine for smallpox and drugs of all kinds. I’m sure that some of them are deadly poison. He’s apt to be more than sick if he tries it.”

Presently the trail wound into the hills. It went up and up and up, and then down and then up again. It skirted deep ravines and dangerous precipices. It crossed the wide basin of a lake.
