"He was a prisoner of Madero, but he has escaped, and is now lying wounded at a spot I will guide you to."

"Himmel! Yack Merrill a prisoner, alretty!" gasped Herr Geisler.

"Not only Master Merrill, but two boy friends of his, an old gentleman, whom I should imagine was their instructor, and a cowboy."

"Yes, it must be them!" exclaimed Mr. Merrill. "But how, in the name of all that's wonderful, did they come across the border? I thought they were at the Haunted Mesa, in New Mexico."

"It is too long a story to relate to you now, señors," rejoined Bob Harding, "I may tell you, though, that they are safe at the hacienda of a friend. But your boy is seriously wounded, and must see you at once."

"Good Heavens, Geisler! This is terrible news, Mr.—Mr.——"

"Mr. Allen, of New York," put in Harding glibly.

"Terrible news that Mr. Allen of New York brings us. You were with them, Mr. Allen?"

"I was, sir. In my capacity as war correspondent for the Planet, I was with Madero's column. But, in the moment of defeat at the hands of the regulars, the miserable greasers turned on me as a gringo. I was compelled to flee for my life. First, however, I cut the bonds of our young friends and their comrades, and under cover of night we escaped."

Bob Harding was certainly warming to his subject as he went along. Mr. Merrill regarded him with gratitude.
