"Well, you see, I don't know how I happened to do it. They forced me to write that letter against my will, two of them standing over me with drawn daggers while I was writing, and prodding me a bit whenever I refused to put down the words Pacheco ordered written."

"Then Pacheco speaks English?"

"As well as I do."

"What does he look like?"

"I don't know."

"How is that?"

"He kept his face concealed with his serape quite up to his eyes."

"Thar's a mystery about Pacheco," broke in Bushnell. "No one seems ter know jest what ther varmint looks like."

"Go on, professor," urged Frank; "tell us just how you escaped."

"I tell you I do not know myself. All I know is that they tied me to a horse, and brought me across a plain of burning sand, where I nearly perished for want of water, and was nearly sawed in two by the backbone of the horse I rode. I believed it was a case of gone goose with me. At last they camped in a wild spot, and I was so badly used up that I could scarcely eat or do anything but lay around and groan. They seemed to think there was no need of watching me very closely, and I noticed that I was alone sometimes. Then, feeling utterly reckless, I began to watch for a chance to sneak away. I didn't care if I were shot, or if I escaped and perished from hunger and thirst. I was bound to make the attempt. Last night I made it. A saddleless horse strayed along where I was, and I made a jump for the animal. Before they knew what I was doing, I was on the beast's back and yelling into its ears like a maniac. The horse scooted out of the camp, and I clung on. The bandits pursued me, and everything else is a haze till I heard Frank calling for me to jump off. I recognized his voice and fell off the horse, although I had not the least idea in the world where I was."
