"Rhoda!" cried Nan, "you can't see that through those glasses."

"No; I cannot distinguish the horsemen. But I can see the little flashes moving across the saddle of the Gap and down into the valley on this side. And I know they are Mexicans because those flashes are the sun's rays shining on the silver trimming on their sombreros. Yes, they are Mexicans."

"Glory be!" exclaimed Bess. "Can you be sure of all that?"

"More. Poor Mexicans—the peons who come up here to find work—do not wear such sombreros. Nor do many Mexicans waste their money in such fashions nowadays. But there is a class that dress just that fancily."

"Who are they?"

"Men that the ranchers here will not want to see. I know that daddy will ride over to the rodeo behind us, or I would turn about now and run to tell him. There! they are gone. There must have been a dozen of them."

"But who are they?" demanded Nan, anxiously.

"Of course, I am not positive. But I think," said Rhoda, closing the glasses and putting them in the case again, "that they are a band of wanderers. Perhaps a raiding party led by one of the so-called 'liberators' of Mexico. You know, there are more 'liberators' in Mexico than you can shake a stick at," and the girl of Rose Ranch laughed.

"You mean bandits!" cried Nan.

"Well, that is a harsh word. They are political leaders for the most part. Sometimes they become important leaders. But when they come over on this side of the Border they need just as close watching as a pack of wolves."
