The whip was extended in front of her, now, and she was moving it gently from side to side. The snake had caught sight of it, and was following it with its eyes, swaying in unison with the whip’s motion.

Never staying the steady movement of her arm, Helen crept forward, whispering reassurance to the dog, until at last, still waving the whip, she dropped to one knee and slipped her fingers under his collar. He stopped his growling and nestled to her with a little whimper. When she commanded him to charge he dropped to his belly and lay perfectly still, his eyes fixed upon the snake.

“If you can manage to turn the thing’s head a bit, little girl;—” it was the man who spoke, in a low, level voice—“so he can’t notice what I’m doing, I’ll fix him.”

With a little nod, Helen stood up and began moving sidewise, still swinging the whip. Thoroughly hypnotized, the snake swayed with its movement, those beady little eyes never leaving it. The rattler did not see the stealthy glide of the man’s hand, or the gleaming steel that was presently leveled at that flat, venomous head. An instant after there was a sharp report, and the snake was whipping the desert in its death struggle as Helen again caught the terrier by the collar. The man essayed to rise, and sank back with a sharp exclamation of pain.

“I guess I’ve hurt my foot,” he said, answering Helen’s look of inquiry.

“I—my horse took to pitching, and slung me here,” he went on, sitting up. “I can’t think what got the fellow, or me either,” he added, with a look of chagrin. “I never thought I needed a bucking-strap; but it seems as if I did.”

He spoke lightly, partly to hearten the girl, who was white and shaken, after her horrid experience, and partly to draw her attention from the victim of his shot, now stretched on the desert.

Another effort and he got to his feet; but the first attempt to step brought him to one knee, frowning with pain.

“And I don’t suppose there’s a stick in sight, that would give me any support,” he said, looking about.

“I’m afraid not,” Helen answered, following his glance; and then she remembered.
