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.
They lost no time, but, catching their horses, bridled them, and rode rapidly down the hill.
Though somewhat relieved at seeing the wagon, Von Bloom was still apprehensive.
As they approached, they perceived the two horses standing beside it, and tied to the wheels, the cow also was there--but neither goats nor sheep were in the neighbourhood.
There was a fire burning in the rear of the hind-wheels, and a dark mass underneath the wagon, but no human form could be observed.
The hearts of the horsemen beat loudly as they advanced.

Their eyes were bent earnestly upon the wagon.

They felt keen anxiety.
They had got within three hundred yards, and still no one stirred--no human form made its appearance.
