“It wasn’t our yelling,” said Uncle John, as delighted as even the father could be; “it was the yelling of whoever is inside, there, that frightened the baby. Thank goodness the dear child could sleep during all these weary hours, when we have been wearing our hearts out with anxiety.”

“We have yet cause for anxiety,” declared Patsy, “for little Jane is not rescued yet, by any means, and presently the poor thing will become very hungry and suffer for lack of food. We now know where baby is, but we can’t get at her; nor can Mildred or Inez find a way to get her out, or they would have done so long ago.”

“Very true,” agreed Helen Hahn, gravely. “Unless we can soon find a way to get to them, all three will starve.”

“Why, we will pull down the wall!” cried Arthur.

“Dynamite it!” piped Bul Run.

“Be sensible!” counseled Uncle John sternly. “We are wasting precious time. Miguel,” turning to the ranchero, “get some of your men, with picks and crowbars, and fetch them here quickly.”

The Mexican, who seemed bewildered by the discovery of the missing ones, although he had himself been the first to suspect where they were, started at once to obey this order. When he had gone, Patsy said:

“Of course there is some easy way to get inside the wall, and to get out again. Are we so stupid that none of us can penetrate the secret of the cunning Spaniard who built this place?”

The challenge merely led them to regard one another with perplexed looks.

“The fact that they’re alive, after all these hours,” said young Hahn, “is proof that they are supplied with air, and plenty of it. Then there is an opening, somewhere or other.”
