Although the moon was in the sky, only a small part of its light penetrated the cañon. Peering into the darkness, Vose dimly made out the forms of the four animals, who, having ceased their cropping of the grass, had lain down for the remainder of the night. They were so near that they could not be stampeded or stolen without the effort being known to the sentinel.
It would have been the height of rashness to start a camp fire, for all the figures within its circle of illumination must have formed the best of targets for their stealthy foes. As it was, an enemy would have to steal from the gloom and approach near enough to touch them, before striking a blow or firing a shot.
Vose Adams, with his Winchester in his right hand and held close to his side, took his seat on the ground, resting his back against the nearest boulder. As a rule, a sentinel can keep awake for an extended time only by motion and exercise, such as walking to and fro, but the trained hunter often takes the risk and there is little danger of his succumbing, especially after he has just finished a nap, as was the case with the guide.
Thus seated, with the boulder rising several feet above his head, Adams’s only reliance was upon his keenness of hearing and sight.
He had not waited long when he saw proof of what the captain had told him: the animals were restless, or rather one of them was. The quadruped thus affected was Hercules, his own mule, who, although lying down, twice rose to his feet, shifted his position and lay down again. Then he sniffed as if the air contained an odor that was displeasing to him.
“I wouldn’t think much of it, if it was one of the horses,” reflected his master, “but Hercules has brains; 288 he knows more’n all the others together, and yet it may be it ain’t that after all.”
One of the singular facts regarding cattle and other quadrupeds is that they are sometimes troubled with disquieting dreams, the same as ourselves. This trifling cause has resulted many a time in the stampeding of a drove numbering tens of thousands.
“I’ve knowed Hercules to kick and snort in his sleep, and one time he come mighty near breakin’ a leg of mine; howsumever, I don’t think that’s the trouble with him to-night. I ’spect it’s Injins this time!”
When Captain Dawson lay down to sleep and Vose Adams assumed his place as sentinel, the moon was near the zenith, but the contour of the cañon shut out its beams. While Vose was striving to pierce the gloom, over and about the four animals, he noted a flickering tremor against the vast wall which formed the other side of the cañon. A faint, fleecy veil of moonlight having been lifted over the mountain crests, was now flung downward and caught against and suspended upon the projecting rocks and crags. It was but a frosty shimmer, but the veil dangled lower and lower, pendant here and there until the fringe rested on the bottom of the gorge.
