“That’s surely the truth,” laughed Donald, “but somehow or other, we seem to have a faculty of getting mixed up in all sorts of things.”

“That’s because you are always trying to help some one out of trouble,” declared Pedro. “If it had not been for me, you would never have been mixed up in this at all.”

“It does look that way, doesn’t it?” laughed Adrian. “But appearances are sometimes deceitful, eh Don?” and he gave Donald a knowing look.

“They sure are; but let’s be hunting a place where we may be of service.”

“I’ll tell you what,” exclaimed Adrian after they

had stood undecided for several minutes, trying to decide upon a position of vantage, “let’s station ourselves on that little knoll just above the door. Then if any should get by those guarding the river entrance I could pick them up with my rifle; while if any should be able to dash past the captain’s party, you can stop them with your Colt.”

“How about me?” asked Pedro.

“You can either stay with us, or follow Don Antonio.”

“I think I’ll stay with you. As you say, you seem to have a faculty for getting mixed up in things and this is one of the things I want a hand in.”

The boys had hardly reached the place they had selected, when a shot from the river front told that the flanking party had taken its position and a minute later the boys could hear the blows that were being rained upon the door to force it from its place.
