“I stood upon the fore-chest of my wagon for nearly two hours, lost in wonder at the novel and beautiful scene which was passing before me; and had some difficulty in convincing myself that it was a reality which I beheld, and not the wild and exaggerated picture of a hunter’s dream. During this time their vast legions continued streaming through the neck in the hills, in one unbroken, compact phalanx.” It has sometimes happened that a flock of sheep has strayed into the line of march. In such cases the flock has been overlapped, enveloped in the springbok army, and forced to join in the march. A most astonishing example of the united power of the springbok was witnessed by a well known hunter. Just as the lemming hosts are attended by the birds and beasts of prey of their own country, so it is with the springbok. These parasites do not attack the main body, but watch for the stragglers and pounce upon them. During the passage of one of these springbok armies a lion was seen in the midst of the antelopes, forced to take unwilling part in the march. He had evidently miscalculated his leap and sprung too far, alighting upon the main body. Those upon whom he alighted must have recoiled sufficiently to allow him to reach the ground, and then the pressure from both flanks and the rear prevented him from escaping from his strange captivity. As only the front ranks of these armies can put their heads to the ground, we very naturally wonder how those in the middle and rear can feed. The mode which is adopted is equally simple and efficacious. When the herd arrives at pasturage, those animals which occupy the front feed greedily until they can eat no more. Then, being ruminants, they need rest in order to enable them to chew the cud. So they fall out of the ranks and quietly chew the cud until the column has almost passed them, when they fall in at the rear, and gradually work their way to the front again. As to water, they do not require it, many of these South African antelopes possessing the singular property of being able to exist for months together without drinking. Dr. Livingstone has offered a very remarkable theory on this subject, but the limited space will not permit me to cite it. Let us again visit in imagination a different part of the world, and suppose ourselves to be on the prairies of North America. There we find another ruminant, the bison, wrongly called the buffalo. This creature migrates with tolerable regularity, and not many years ago, when the red men possessed the vast expanses of North America, the native tribes were dependent upon the bison for their very existence. The bison was to the red Indian what the seal tribe is to the Esquimaux.
