At last they reached the bottom, forded the swirling stream, and began clambering up a trail as steep as the first on the other side. Soon the river was lost to view again, for once more the trail had been cut through a seemingly impenetrable chaparral of buckthorn, manzanita and scrub oak. Around and about tributary cañons they wound their way, and at last reached the end of the steep climb. For a quarter of a mile now the trail followed the backbone of a ridge, then entered a cañon that eventually spread out into a pine-bordered plateau on the mountainside. Just ahead lay Poison Oak Ranch. Beyond, the deep, dark forest extended in miles numbered by hundreds to the snow-mantled peaks of the Sierra Nevada range. While it was possible to reach Poison Oak Ranch from this side of the river, the journey on Shank's mare would have taken on something of the nature of an exploring expedition into unmapped lands. Occasionally hunters wandered to or past the ranch on this side; but for the most part any one who fancied that he had business at Poison Oak Ranch came over the narrow trail that connected the spot with outside civilization. Few entertained such a fancy, however, for Poison Oak Ranch, secluded, hidden from sight, tucked away in the Hills of Nowhere, and difficult of access, was owned and controlled by a clannish family that had little in common with the world. There was a large log house that Adam Selden's father had built in the days of '49, in which the Old Man Selden of today had first opened his eyes on life. There were several lesser cabins in the mountainside cup, two of which were occupied by Hurlock Selden and Winthrop Selden and their families. The remaining two boys, Moffat and Bolar, lived in the big house with Jessamy, her mother, and the wicked Old Man of the Hills.
