"Ha, boy, are you alone?" demanded the man, who was none other than Captain Arguez.
"I am," answered Ralph.
"And what brought you here?"
"I was out looking for a lost mustang, and missed my way."
"Ha, that is what the other boy told me!" muttered Captain Arguez, half savagely.
"The other boy? Then you have seen my brother?"
"Yes."
"Where is he now?"
"I cannot tell you. He ran away, taking one of my soldier's mustangs."
"But I don't understand," stammered Ralph. "Are you a Mexican army officer?"
"I am."
"And Dan was with you?"
"I think he fell in with us by accident, and he got away just as we were having a brush with some of your accursed Americans." The Mexican captain looked around suspiciously. "You are quite sure you are alone?"
"Yes, señor."
"You have two ponies."
"One belongs to my brother. He got on the white mustang,—the one that ran away,—and that is the last I saw of him. You have no idea where he is now?"
