“We must not forget,” replied Louise, “that of all our numerous states California has the most romantic history. It wasn’t so long ago that the Spanish don flourished in this section and even yet it is more Spanish than American except in the big cities.”

“As for smuggling,” added Runyon, “that is going on to-day—as merrily as in the days of the famous Leighton, if on a smaller scale. I’ve some choice cigars over at my ranch that have never paid duty, and I’ve an order with the smuggler for more. So, after all, there’s nothing very astonishing in Mildred Leighton’s story.”

“The wall we have practical evidence of,” said Uncle John. “I suppose it will hold its secret rooms for many years to come, for these adobe dwellings are practically fire-proof and are built to defy time.”

“But about Mildred’s fortune,” cried Patsy. “Don’t you suppose it is hidden, after all, some place in the wall?”

“From what I have heard of Cristoval,” said Arthur in a reflective tone, “he was not considered a dishonest man, but rather miserly and grasping.”

“My father,” explained Mildred, “trusted him fully until we went away and could get no answer to his letters. The old Spaniard was very fond of me, also, and he would hold me in his arms and say that one day I would be a rich lady, for my father and he were both making my fortune. I was very young, as you know, but I never forgot that statement.”

“Suppose,” suggested the major, “we make another and more thorough search of those secret rooms.”

“We will do that,” replied Arthur promptly. “It is too late to undertake the task to-night, but we will begin it right after breakfast to-morrow morning. Inez, I wish you would slip down to the quarters and ask Miguel to come and help us. Tell him to be here at nine o’clock.”

The girl nodded, gave the baby to Mildred and stole quietly out of the court.
