They started the following morning at daybreak, and, at the same time, the Caffres took their departure to their own country. The ground over which the caravan travelled was stony and sandy at intervals, and they had not proceeded far before they again discovered a great variety of game dispersed over the level plain. They did not, however, attempt to pursue them, as they were anxious to go on as far as possible, so as to give the oxen an opportunity of picking up what little food they could during the middle of the day, at which time the Major and Alexander proposed that they should go in pursuit of game. But before they had travelled three hours, they were surprised at a cloud of dust, which obscured the horizon, in the direction they were proceeding.
“What can that be?” said Alexander.
“I think it is springbok,” said Bremen the Hottentot.
“Springbok, why, there must be thousands and thousands of them.”
“I believe that Bremen is right,” said Swinton; “it must be one of the migratory herds of springboks; I have never seen them, but I have often been told of them.”
The body of antelopes now advanced towards them, keeping on a straight path; and to state their numbers would have been impossible: there might have been fifty or a hundred thousand, or more. As far as the eye could see in any direction, it was one moving mass covering the whole plain. As they approached the caravan, those nearest huddled on one side and occasionally bounded away with the remarkable springs made by this animal, and from which it has its name, alighting not upon the earth, but, for want of room, upon the backs of its companions, and then dropping in between the ranks.
A hazy vapour arose from these countless herds as they moved on, and more than once the Hottentots, who were standing on the waggons, which had been stopped as the herd came up to them, pointed out a lion which was journeying with the crowds to feast at his leisure. The animals appeared very tame, and several were killed close to the wheels of the waggons, for the evening’s supper. Notwithstanding that the herd moved at a rapid pace, it was more than two hours before the whole had passed by.
“Well,” observed Alexander, “I can now say that I have seen no want of game in Africa. Where will they go go?”
“They will go directly on to the southward,” replied Swinton; “the migration of these animals is one of the most remarkable proofs of the fecundity of animal life. Like the ants, they devour everything before them; and if we journey in the direction they have come from, we shall find no food for the cattle until after the rains. After the rains fall, these animals will return to their former pastures. It is the want of food which has brought them so far to the southward.”
“Their track is evidently from the north and eastward,” said the Major; “had we not better change our course more to the northward?”
