CHAPTER XIX. THE TERROR OF THE PRAIRIE.

There was no need of Lightning Jo telling what it was that so startled him, for following the direction of his own gaze, every eye saw it on the instant.

On the upper margin of the precipitous chasm or canon, through which they were making their way, at a point about a hundred feet above and directly over them, was the apparition which had so startled Captain Shields when in Dead Man’s Gulch. The mustang was standing as motionless as then, and the same quadrupedal nondescript was perched upon his back, its black head turned a little to one side, while it was evidently gazing down upon them with a fixed, intense stare.

“The devil will be to pay now,” growled Jo, just loud enough to be heard in the roaring wind; “but it’s too late to put back, and we’ll press ahead.”

And resolutely compressing his lips, he drove his mustang to the head of the cavalcade and forced him into a gallop along the canon, the others, of course, following his example.

Neither Egbert nor Lizzie had made the least reference to this apparition, while in converse with the scout, for the reason that each knew he bore the reputation of being a practical man, and would only laugh and tell them that it was a “spook,” that their fright and sufferings caused to appear to their own minds—an explanation which both were inclined to accept up to this point.

But Jo had scarcely started ahead, when several large drops of rain pattering here and there in the gorge, warned them that the threatened deluge was at hand. The winding of the canon, at the point over which they were now hurrying, was such that there was comparatively little about them, although it moaned and sobbed over their heads like the desolate wailing of lost spirits.

“Hurry up, Jo!” yelled Gibbons, from directly in the rear of the lovers, “or we shall be drenched!”

No need of shouting to the scout, who at that moment made a dash a little to one side, and then wheeling his steed squarely about, halted and motioned to the others to join him on the instant.
