“It’s one of the men who were with us on last night’s expedition,” explained Don Rafael as the man approached near enough to be recognized. “I wonder what he wants.”

They were not kept long in suspense, for the messenger, seeing that they were waiting, hastened his footsteps and soon reached them.

“What is it, hombre?” asked Don Rafael.

“A serious mistake was made last night.”

“How so?”

“A lot of rifles and a machine gun were left on the American side of the river.”

“What!” exclaimed Don Rafael “A machine gun?”

“Si, Señor!”

“What’s to be done?”

“That’s what Don Pablo wants to know. He told me to say that he has discovered that the guns are right where they were left and so far have not been seen. One of the men has been posted on this side of the river to watch that no one molests them. Don Pablo thinks if they are not discovered during the day, we can easily bring them over right after dark, so that they can come up here with the others!”
