"'I understand what you want, Colonel; seek no further, for I am the man you stand in need of. Tomorrow at sunrise I will start: and within two months I pledge myself to give you the most explicit information, and tell you what you may have to fear, and what truth there is in all that is being said around you.'"

"The Colonel thanked me warmly, and the next morning I set out on my tour of investigation, as we had arranged."

"Well," the Captain exclaimed, who had followed this long story with ever increasing interest; "and what information have you picked up?"

"This information," the hunter answered, "is of a nature far more serious than even public report had said. The situation is most critical, and not a moment must be lost in preparing for defence. I was going to San Estevan, where Colonel Don Gregorio must be awaiting my return with the utmost impatience, when I thought of seeing whether the Post of San Miguel, which had been so long unoccupied, had received a garrison. That is how chance, my dear Captain, made us meet here when I thought I should see you at the Presidio."

The Captain shook his head thoughtfully. "A month ago," he said, "Don Gregorio ordered me to come here and hold my ground, though he did not inform me of the motives that compelled him so suddenly to place San Miguel in a state of defence."

"Well; now you know the reasons."

"Yes; and I thank you for having told me. But, between ourselves, are matters so serious as you lead me to suppose?"

"A hundred times more so. I have traversed the desert in all directions; I have been present at the meetings of the chiefs—in a word, I know the most private details of the expedition that is preparing."

"¡Viva Dios! I will not let myself be surprised—be at your ease about that; but you were right in advising me to ask for help, as my garrison is too weak to resist a well-arranged assault. This morning's attack has made me reflect; so I will immediately—"

"Do not take the trouble," the hunter interrupted him; "I will act as your express."
