She heard a faint rustling of the sand beside her and could hardly keep from turning her head again. But she succeeded. Waves of coldness broke on her mind; her whole body would have shuddered had not fear chilled her into motionlessness. All reason told her that it was madness to sit there with the stealthy horror sliding closer; even now it might be too late. If she rose the shaggy form might spring from the ground at her. Perhaps the wolf had treasured up the pain from the day before and now—

A black form did, indeed, rise from the ground, but slowly. And standing on three legs, Bart stood a moment and stared in the face of the girl. The fear rushed out of her heart; and her face flushed hotly with relief. There was no enmity in the steady stare of the wolf-dog. She could feel that even though she did not look. Something that Whistling Dan had said long before came to her: "Even a hoss and a dog, Kate, can get terrible lonesome."

Black Bart moved until he faced her directly. His ears were pricking in eagerness; she heard a snarl, but so low and muffled that there was hardly a threat in it; could it be a plea for attention? She would not look down to the sharp eyes, until a weight fell on her knees—it was the long, scarred head of the wolf! The joy that swelled in her was so great that it pained her like a grief.

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.
