Uncertain.

While riding along about dark we heard a wolf howl behind us. My Lipan guide stopped short and assumed a listening attitude. In a few moments another answered, way to the right. Still the Indian listened so intently that his form seemed perfectly rigid. Then another set up a howl on our left. “Umph, lobo,” said the Lipan, in a tone of relief. I can’t say that I admired the music of the wolf at any time, but it certainly never had a more unmusical sound than on that occasion, and when I saw that even an Indian’s ears were uncertain whether it was a wolf or a Comanche, I felt the cold chills creeping over me.
