With a quick jerk Gardley reined in his horse and wheeled about, watching the riders for a moment; and then, setting spurs to his beast, he was off down the trail after them on one of his wild, reckless rides. Down through the mesquite he plunged, through the darkening grove, out, and up to the top of the mesa. He had lost sight of his quarry for the time, but now he could see them again riding more slowly in the valley below, their horses close together, and even as he watched the sky took on its wide night look and the stars blazed forth.

Suddenly Gardley turned sharply from the trail and made a detour through a grove of trees, riding with reckless speed, his head down to escape low branches; and in a minute or two he came with unerring instinct back to the trail some distance ahead of Forsythe and Rosa. Then he wheeled his horse and stopped stock-still, awaiting their coming.

By this time the great full moon was risen and, strangely enough, was at Gardley's back, making a silhouette of man and horse as the two riders came on toward him.

They rode out from the cover of the grove, and there he was across their path. Rosa gave a scream, drawing nearer her companion, and her horse swerved and reared; but Gardley's black stood like an image carved in ebony against the silver of the moon, and Gardley's quiet voice was in strong contrast to the quick, unguarded exclamation of Forsythe, as he sharply drew rein and put his hand hastily to his hip for his weapon.

"I beg your pardon, Mr. Forsythe"--Gardley had an excellent memory for names--"but I thought you might not be aware, being a new-comer in these parts, that the trail you are taking leads to a place where ladies do not like to go."

"Really! You don't say so!" answered the young man, insolently. "It is very kind of you, I'm sure, but you might have saved yourself the trouble. I know perfectly where I am going, and so does the lady, and we choose to go this way. Move out of the way, please. You are detaining us."

But Gardley did not move out of the way. "I am sure the lady does not know where she is going," he said, firmly. "I am sure that she does not know that it is a place of bad reputation, even in this unconventional land. At least, if she knows, I am sure that her father does not know, and I am well acquainted with her father."
