The joyful exclamation he uttered awoke the sleepers, who immediately sprang to their feet; and all three stood gazing at the welcome sight.

As they continued to gaze, their joy gradually gave place to feelings of surprise. Was it their wagon, after all?

It certainly looked like theirs; but it was a full half-mile off, and at such a distance one wagon would look just like another. But what led them to doubt its being theirs? It was the appearance of the place in which they saw it. Surely it was not the same place in which they had outspanned!

Theirs had been left in an oblong valley between two gentle ridges—in such a valley was this one standing. Near a pool formed by a spring—here, too, was the same, for they could perceive the water shining. But in all other respects the situation was different. The surface of the valley in which their wagon had been left was covered, both sides and bottom, with a verdant carpet of grass; whereas the one now before their eyes was brown and bare! Not a blade of grass was to be seen—the trees seeming to be the only things that had any verdure. Even the low bushes appeared to be destitute of leaves! The scene had no resemblance whatever to that where they had outspanned. It must be the camp of some other travellers, thought they.

They had fully arrived at this conclusion, when Swartboy, whose eyes had been rolling about everywhere, now rested upon the ground at his feet. After a moment's observation—which the increasing light now enabled him to make—he turned suddenly to the others, and directed their attention to the surface of the plain. This they saw was covered with tracks, as if a thousand hoofs had passed over it. In fact, it presented the appearance of a vast sheep-pen; so vast, that as far as their sight extended, they beheld the same tracked and trampled appearance!

What could this mean? Hendrik did not know. Von Bloom was in doubt. Swartboy could tell at the first glance. It was no new sight to him.

“All right, baas,” he said, looking up in his master's face. “Da's da ole wagon!—da same spring an vley—da same place—dar hab been um trek-boken!”

“A trek-boken!” cried Von Bloom and Hendrik, in a breath.

“Ya, baas—a mighty big one too; das da spoor of dem antelope—See!”

Von Bloom now comprehended all. The bareness of the country, the absence of the leaves on the lower bushes, the millions of small hoof-tracks, all were now explained. A migration of the springbok antelope, a “trek-boken,” had swept over the spot. That it was that had caused such a mighty change. The wagon they saw was theirs, after all.
