“A white man?”

“Yah, sieur, it is so. It smell white man.”

The three looked at each other with uplifted eyebrows, while Klaas turned the necklet over in his hand.

“That settles it,” said Hume. “Let us search for the stranger. But, as he may be on the look-out, I will make a circuit to the top of the krantz, while you go towards the base, and leave the bag on some rock that can be seen from above.”

This was done. Webster placed the bag on a rock well out in the river, and then retired towards the camp, while Hume watched behind an aloe. For an hour he waited without seeing aught, then descended to the bottom, and himself examined the cave, without, however, finding any fresh evidence. He then returned to the camp.

“It is no use,” he said; “we should be wasting valuable time in searching for this mysterious being. If he had some design in taking that map we should be serving his purpose by lingering here. Inspan, Klaas.”

The oxen were yoked, and the waggon moved on slowly, Hume going ahead to mark out the road, and Webster, taking the “trek-tow,” or looped rheim to guide the leaders.

Before dusk they outspanned on a grassy knoll, and set to work at once with axes to build a fence round. The oxen were driven to the water, allowed to graze a short time, then driven into the enclosure and tied up. Fuel was stacked up in preparation for fires, supper was made and eaten, and then they sat talking about the man of the krantz until the clamorous howling of jackals warned them to be on watch. Miss Anstrade retired to the waggon, the sail was drawn down and two huge fires lit, one on either side of the oxen. Hume crept under, the waggon, and was soon in a deep sleep, while Webster and Klaas, on either side the waggon, kept watch.
