Three years later, however, I met with an adventure which removed the last vestige of doubt from my mind. In the autumn of 1880, with five other Rangers, under command of a lieutenant, I was stationed at Eagle Pass, on the Rio Grande. About the middle of November I was sent to San Antonio with important despatches for the colonel commanding. I was selected for the trip because I had the fleetest horse of any man in the force, a big black thoroughbred, for which I had paid three hundred dollars when he was only two years old, and at a time, too, when horseflesh was cheap. For three years I had ridden this horse daily on all our scouting expeditions. He had borne me safely through many dangers, and I loved him almost as if he had been a human being. I left San Antonio on my return one morning at eleven o'clock and rode seventy miles by nine o'clock that night, arriving at the Nueces River and Turkey Creek bottoms. The weather became threatening in the afternoon, and at night dense clouds obscured the light from the stars, and as there was no moon it became so appallingly black when we entered the thick timber of the "bottoms" that I could not see an inch before my eyes, and even my horse could not find his way around the trees, bushes, and fallen timber. There was no rain, no lightning, no thunder, and no wind--simply a thick pall of clouds which seemed to rest upon the tops of the trees--while a curious soft murmuring sound seemed to come from the bottom lands. I would have stopped immediately upon reaching the timber, but I had heard that afternoon that Indians had been seen along the river within the past twenty-four hours, and I had noticed the trail of what I believed to be Indian ponies crossing my road about six o'clock. So somehow or other I felt my way through the pitch-darkness till we were perhaps three hundred yards from the edge of the Nueces bottom. Then, dismounting, I took off my saddle and, letting down my lariat, looped the end around my left wrist so that my horse could graze, and yet waken me if he got too far away. Lying down under a large live-oak with my head on the saddle, I soon went to sleep with the subdued murmuring sound still echoing in my ears. I intended to rest a few hours, until the clouds lifted, and then continue my journey to a settlement twenty miles farther on. The tree under which I lay was a very large one, and I found next morning that the top limbs were dead, the tree having been struck by lightning some years before.
