"If those are not smoke signals," said Frank, "I'm a chump! In that case, it's likely I'll have Indians to deal with if I keep on. Perhaps I'd better turn back."

For something told him that he was the object of those signals, and this was an Indian method of communication. He sat still for some time, watching the smoke fade in the upper air, which it did slowly. At last, however, it was gone, and the clear atmosphere held no black signal of danger.

Frank's curiosity was aroused. He longed to know the meaning of those signals. Having looked to his weapons, he rode on slowly, keenly on the alert.

Coming through a narrow gorge into a valley that looked barren enough, he suddenly snatched forth a revolver and cried:

"Halt, there! Stop, or——Why, it's a woman!"

For he had seen a figure hastily seeking concealment amid some boulders. At sound of his voice the figure straightened up and turned toward him.

Then he was more amazed than ever, for he saw a dark-faced Mexican girl, wearing a short skirt and having about her neck a scarlet handkerchief. Her[Pg 104] head was bare, and her dark hair fell over her shoulders. She looked like a frightened fawn.

No wonder he was astonished to behold such a vision in that desolate part of the mountains. She seemed trembling, yet eager, and she started to advance toward him.

"Oh, señor!" she said, in a voice that was full of soft music, "eet mus' be you are good man! Eet mus' be you are not bad an' weeked. You would not hurt Gonchita?"

"Not on your life!" exclaimed Merry, at once putting up his revolver.
