She stretched out her hand, slowly, slowly towards that head. And Black Bart shrank and quivered, and his lips writhed back from the long, deadly teeth, and his snarl grew to a harsher, hoarser threat; still he did not remove his head, and he allowed the hand to touch him between the eyes and stroke the fur back to between the ears. Only one other hand had ever touched that formidable head in such a manner! The teeth no longer showed; the keen, suspicious eyes grew dim with pleasure; the snarl sank to murmur and then died out. "Bart!" commanded the girl, sharply. The head jerked up, but the questing eyes did not look at her. He glanced over his shoulder to find the danger that had made her voice so hard. And she yearned to take the fierce head in her arms; there were tears she could have wept over it. He was snarling again, prepared already to battle, and for her sake. "Bart!" she repeated, more gently. "Lie down!" He turned his head slowly back to her and looked with the unspeakable wistfulness of the dumb brutes into her eyes. But there was only one voice in which Bart could speak, and that was the harsh, rattling snarl which would have made a mountain-lion check itself mid-leap and slink back to its lair. In such a voice he answered Kate, and then sank down, gradually. And he lay still. So simply, and yet so mysteriously, she was admitted to the partnership. But though one member of that swift, grim trio had accepted her, did it mean that the other two would take her in? A weight sank on her feet and when she looked down she saw that Black Bart had lowered his head upon them, and so he lay there with his eyes closed, dreaming in the sun. CHAPTER XXVIII THE TRAIL Bandages and antiseptics and constant care, by themselves could not have healed Black Bart so swiftly, but nature took a strong hand. The wound closed with miraculous speed. Three days after he had laid his head on the feet of Kate Cumberland, the wolf-dog was hobbling about on three legs and tugging now and again at the restraining chain; and the day after that the bandages were taken off and Whistling Dan decided that Bart might run loose. It was a brief ceremony, but a vital one. Doctor Byrne went out with Barry to watch the loosing of the dog; from the window of Joe Cumberland's room he and Kate observed what passed. There was little hesitancy in Black Bart. He merely paused to sniff the foot of Randall Byrne, snarl, and then trotted with a limp towards the corrals.
