"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.
