Their wild cries echoed in the canyon for a short time, and then all was still once more. The sound which had frightened them was not repeated, but it had been sufficient as it was to start me speculating on the possible horror which lurked in the shadows at my back. Fear is a relative term and so I can only measure my feelings at that time by what I had experienced in previous positions of danger and by those that I have passed through since; but I can say without shame that if the sensations I endured during the next few minutes were fear, then may God help the coward, for cowardice is of a surety its own punishment.

There also came to my nostrils a faintly pungent odor, and I could only assume that I had been overcome by some poisonous gas, but why I should retain my mental faculties and yet be unable to move I could not fathom. I lay facing the opening of the cave and where I could see the short stretch of trail which lay between the cave and the turn of the cliff around which the trail led. The noise of the approaching horses had ceased, and I judged the Indians were creeping stealthily upon me along the little ledge which led to my living tomb.

Their eyes were set at the extreme sides of their heads a trifle above the center and protruded in such a manner that they could be directed either forward or back and also independently of each other, thus permitting this queer animal to look in any direction, or in two directions at once, without the necessity of turning the head. The ears, which were slightly above the eyes and closer together, were small, cup-shaped antennae, protruding not more than an inch on these young specimens. Their noses were but longitudinal slits in the center of their faces, midway between their mouths and ears.
