"I don't know what he's up to, of course," replied Hi Lang. "I do know that he is the same fellow who left the range after we folks were shot at there, for the hoof-prints of his pony are the same. He is watching us, and we'll hear from him later," he declared impressively.

THE CROSS ON THE DESERT

"You should have let me take a shot at him when I had the chance," grumbled Hippy.

"Time enough to shoot when we are shot at," rebuked Grace. "We are not starting trouble, but when it comes we know how to meet it. Do we not, Mr. Lang?"

Hi Lang nodded enthusiastically.

Grace had been practicing persistently with her Mexican lasso, and was now beginning to learn to rope a pony. That is, she had succeeded, when riding alongside a trotting pony who objected to being caught, in casting the lasso over its head, but so far as catching the hind foot of a moving bronco with her loop, that was far beyond her. Grace doubted if she ever would gain sufficient skill to do that.

Elfreda, too, was an apt pupil and not far behind her companion in casting the rope. She was glorying in the life of the west, which was becoming more and more alluring to her as the days passed.

"Two days more and we'll be in the foothills of the Specters. Maybe you will be able to rope a wildcat there," said the guide, smiling at the two girls.

"Four-or two-legged?" inquired Hippy.
