But he speedily recovered himself, and was sharp enough to comprehend that the animals must have been abstracted very recently, and were within the possibility of recovery. With a muttering exclamation of impatience, he dashed headlong through the bushes into the open space beyond, and stared around. Being at the base of the mountains, he was also on the edge of a broad valley, and the bright moonlight gave him quite an extended view over the broken, rocky country.

It required but one sharp glance of the African to discover, about a quarter of a mile distant, the three horses and one mule, making their way among the boulders and patches of broken land, with all the deliberation with which they would have answered the call to work. Jim paused long enough to see that no one was driving them, when, uttering the exclamation which has been given at the close of the last chapter, he started on a full run after them.

With his usual thoughtlessness, he had come out without his gun, and he was now running at his utmost speed, entirely regardless of his personal danger from the hubbub he was creating, and from withdrawing so far from his base of operations. There was something so singular in the spectacle of these four animals leisurely trotting off over the country, that he ought to have hesitated and attempted to explain the matter before venturing after them in this open, boisterous manner.

It was observable, too, that, immediately after Jim gave the terrific outcry referred to, the slow trot of the animals increased to quite a brisk gait, a thing so unusual on the part of the mule, as to cause no little wonder upon the part of the pursuer.

“Beats all natur’!” he exclaimed, as he struck his foot against a stone, and was almost thrown forward upon his hands and knees. “Fust time I ebber seed dat ole mule raise a trot; split two, free rocks ober his head, smashed all de limbs off a big tree ober his back, but no use, couldn’t get him off a walk, an’ dere he goes now swingin’ ’long like a feller on stilts. Beats all natur’!”

It was indeed so curious, that he paused to take a look at them. Just at that moment they were ascending a small swell; and, as they came in relief against the blue sky beyond, they were as plainly visible as at noon day. It was clear that none of them had a rider upon his back, nor was any one following, except him who was trying so valiantly to recapture them. What then was the explanation of this singular movement?

Jim, who had suddenly resumed his running, as suddenly paused, for he had discovered something.

“Wal, dere! if dat don’t beat eberything! dar’s an Ingin right in among dem hosses, or else dat switch-tailed mare has got six legs—one or t’oder!”

It would have required a good pair of eyes to notice this curious fact, had not the mare referred to at that moment fallen somewhat in the rear, when the singular addition to her means of locomotion made the usually large eyes of the African considerably larger.

The fact was apparent that a red man was among the quadrupeds, and inciting them to their rapid gait by some outlandish means which seems to come natural to the aborigines, and which, up to this time, had escaped the attention of the pursuer.
