Our quarters were surrounded by a small yard and a fence; the latter was dilapidated, and the gate swung on one hinge. We were seven miles from anywhere, and surrounded by a desolate country. I did not experience the feeling of terror that I had had at Camp Apache, for instance, nor the grewsome fear of the Ehrenberg grave-yard, nor the appalling fright I had known in crossing the Mogollon range or in driving through Sanford's Pass. But still there was a haunting feeling of insecurity which hung around me especially at night. I was awfully afraid of snakes, and no sooner had we lain ourselves down on our cots to sleep, than I would hear a rustling among the dry leaves that had blown in under our beds. Then all would be still again; then a crackling and a rustling--in a flash I would be sitting up in bed. "Jack, do you hear that?" Of course I did not dare to move or jump out of bed, so I would sit, rigid, scared. "Jack! what is it?" "Nonsense, Mattie, go to sleep; it's the toads jumping about in the leaves." But my sleep was fitful and disturbed, and I never knew what a good night's rest was. One night I was awakened by a tremendous snort right over my face. I opened my eyes and looked into the wild eyes of a big black bull. I think I must have screamed, for the bull ran clattering off the piazza and out through the gate. By this time Jack was up, and Harry and Katherine, who slept on the front piazza, came running out, and I said: "Well, this is the limit of all things, and if that gate isn't mended to-morrow, I will know the reason why." Now I heard a vague rumor that there was a creature of this sort in or near the post, and that he had a habit of wandering around at night, but as I had never seen him, it had made no great impression on my mind. Jack had a great laugh at me, but I did not think then, nor do I now, that it was anything to be laughed at. We had heard much of the old Mission of San Xavier del Bac, away the other side of Tucson. Mrs. Kautz decided to go over there and go into camp and paint a picture of San Xavier. It was about sixteen miles from Fort Lowell. So all the camp paraphernalia was gotten ready and several of the officers joined the party, and we all went over to San Xavier and camped for a few days under the shadow of those beautiful old walls. This Mission is almost unknown to the American traveler. Exquisite in color, form and architecture, it stands there a silent reminder of the Past.
