But the spectacle most interesting of all was one afforded by the largest of quadrupeds—the elephant itself; a sight so rare as to well deserve being called wonderful; and so the old jäger, Jan Van Dorn, pronounced it—even he never having witnessed the like before.

During the time they were engaged in raft-building, they had observed elephants on the opposite side of the great river; not a single herd, but straggling bands all moving in the same direction—downward. Day after day they had noticed this stream of the great pachyderms, supposing them to be the same animals that had returned up in the night, and were thus journeying to and fro for food, or water.

Now they had evidence to the contrary, and in less than an hour after embarking. As they passed down, with eyes scanning the plain on both sides of the river, they arrived opposite a wide expanse of wet marsh, or savanna, extending away from the right bank. On this was a herd of elephants, a multitude so vast as to seem all of the elephant kind inhabiting South Africa. The ground was thick covered and black with them for miles upon miles, the whole drove certainly numbering not less than a thousand head! They were up to their bellies browsing on a green sedge—that grew luxuriantly in the wet marshy soil—no doubt the cause of their being so congregated.

To the young Boers it was a sight not less tantalising than strange, and their elders had a difficulty in restraining them. One and all were for bringing the raft in to the bank, landing, and making slaughter among the pachyderms. But the old jäger in command would not listen to this; knowing as he did, that the first shot fired would send the herd helter-skelter, even should they stand to receive a first shot.

Besides, he urged another and more convincing objection. To stalk such game on that ground, bare of trees and other protecting cover, would be attended with the greatest danger. Instead of retreating, just as likely might they charge upon the stalkers, and put them to flight, with scarce a chance of escape.

In fine, the elephants were let alone, though not without sore reluctance on the part of the young hunters. Even the baases disliked it; for it seemed almost as the leaving behind some thousands of pounds of ivory, with as many hundreds of pounds sterling. But it had to be done; the uncertainty, with peril attendant, determining the sacrifice.

And there was still another factor which just then interfered. The raft, hitherto gliding smoothly on at a fair rate of speed, had been found to be gradually slowing, and was now scarce making way at all. The cause was clear enough. Up to this point, or rather down to it, they had been carried along on the current of the inflowing stream, which here came to an end amid the more sluggish waters of the great river.

By Jan Van Dorn this new and unexpected impediment was looked upon with something more than vexation—indeed alarm—the wiser ones sharing it. Before them were long leagues of river navigation; how many they could not tell, or what time it might take to reach the sea. But they knew there was also a rainy season before them, during which the low-lying coast-land becomes a hotbed of malarial fever, almost always fatal to white men. No wonder then at their dreading delay.

It seemed a poor alternative, taking to oars; but they had hopes of again getting into a current farther down, and so took to them. Poling they did not think of now; as, despite the river being at its lowest, it was too deep for that. But there were oars in plenty, with men to man them; so out went they, to be worked with a will.

Notwithstanding, their progress was unsatisfactory, the cumbrous structure refusing to move at a speed of much more than a mile to the hour. And as still further discouragement a long reach of the river—leagues of it—stretched before them, straight as a canal, and to all appearance as stagnant. But this, at first dispiriting, after a little became suggestive. If in directness of course the stream resembled a canal, either of its banks—smooth, firm, and level as they were—might be likened to a tow-path.
