The boys were Chetwood and Paul Winthrop, two brothers, tall, well-built, and handsome. The face of each was browned by exposure, and showed the perfect health that only a life in the open can give.
Chet and Paul lived with their elder brother Allen at a typical ranch home in Idaho, on one of the numerous branches of the winding Salmon River. The home was a rude but comfortable affair, with several outbuildings close at hand, the whole surrounded by a rude but substantial stockade, a relic of the time when troubles with the Indians were numerous.
It was a warm, sunshiny day in August, and the two boys had been down to the river fishing at a favorite deep hole near the roots of a clump of cottonwood trees. Each had a nice mess of fish strung on a brush branch, showing that their quest of game had not been a vain one.
For three years the three Winthrop boys had lived alone at the ranch home. Their former history was a peculiar one, the particulars of which will be given later. Just now we will follow Chet and Paul to the barn, the door to which stood half open.
"Gone!"
