"That man who came to your rescue, who called himself the Hermit of the Grand Canyon, who sought to shun you after his service to you, is either Wallace Weston, or knows something of him, and it is his trail we must pick up on his return to his retreat, and follow to the end, before I am satisfied," Doctor Dick had said to Buffalo Bill. And so it was that the two had met at the deserted camp to pick up the trail of the hermit and follow it to the end, bring what it might to Doctor Dick. The trail was taken up and followed to the brink of the grandest view in all nature's marvels, the Grand Canyon of the Colorado. To a less experienced scout than Buffalo Bill, there would have appeared to be no trail down into the depths of that mighty chasm, and it would have been thought that the one whom they trailed had retraced his steps from there. But the scout was not one to be thrown off the trail by any obstacle that perseverance, pluck, and hard work could overcome, and so he set about finding a way down into the canyon, though there was no trace of a traveled path left on the solid rocks upon which he stood. Doctor Dick's determined assertion that he did not believe his old enemy, Wallace Weston, to be dead, really impressed the scout in spite of the fact that he had guided Lieutenant Tompkins and his troopers in the pursuit of the fugitive soldier, had found the body torn by wolves, dressed in uniform, and with his own saddle and bridle, taken when he had dashed away upon his horse, lying by his side. Still, in the face of all these seeming proofs, the fugitive sergeant might yet be alive and he would do all he could to solve the mystery as to whether he was or not. The scout had been anxious to go alone with the gambler-doctor in the search, for he did have the hope that, if really found, Wallace Weston might be reconciled with Doctor Dick, while, if taken by troopers, he would be returned to the fort and executed, as he was under death-sentence. Buffalo Bill never forgot a service rendered him, and he did not wish to see the sergeant put to death, when he was already believed to be dead, and the secret might be kept. After a long search Buffalo Bill found the perilous path down which the one he followed had gone with his packhorses. He revealed the fact to Doctor Dick, and the two, after a long consultation, decided to take the risk and make the descent into the grand valley. For men with less nerve than these two possessed it would have been impossible; and, as it was, there were times when the winding trail and dangers put their pluck to the test. At last the valley was reached, and, greatly relieved, the two went into camp before prosecuting their search further. The hermit had admitted to Buffalo Bill that he had a comrade dwelling with him in his retreat, wherever the retreat was.
