As it was, they encountered no waterfall, only rapids; which, by a dextrous use of the poles, with one or other of the Macobas all the time at the steering oar, they succeeded in safely running. It was often a close shave though, with wreckage imminent more than once. Once, indeed, the raft grounded upon a subaqueous reef, and threatened going to pieces. But what with the buoyant koker-booms, the reliable lashings of Baavian-touw, and the skill of the Lake Figam boatmen, it was got off again without serious damage.

Rejoiced were all when at length assured that the last of the turbulent rushes had been run, and they were once more in a tranquil current, with the assurance of its extending to a far distance beyond them. They had this confidence from the changed character of the stream, and the scenery on its banks. It now coursed through flat, alluvial land, on both sides wooded to the water’s edge; the trees of great height, and broad leaved, with that lush luxuriance of underwood only found in tropical forests.

Thenceforward it was all plain sailing, and easy; though the steerers had a hard enough task, and required to be continuously at it. For the stream was now winding, often nigh back upon itself like the letter S, and at times near to being as the figure 8. Here, again, it was too deep for polling, but neither were the oars resorted to. Without them the raft made way averaging a league to the hour, and with this all were contented. The Boers of South Africa, as their ancestors by the Zuyder Zee, take things easily. Besides, the rainy season would not set in for another month, and in less than half that time, barring accidents, they should reach the reported Portuguese settlement by the river’s mouth. Thence, getting out to sea, they would escape the fever danger.

Thus reliant, they allowed the raft to glide on, giving it no aid of oars, save the steering one, at which the two Macobas took turn and turn about, having all the work to do. The rest of the people did little or nothing, though the young Boers were busy enough. But with sport, not work; their activity consisting in a display of shooting skill. Large birds were all the time hovering overhead, or flying past—cranes, pelicans, flamingoes, vultures, and eagles—and to bring one of these down with a bullet was the feat on which bets were made.

Many so fell, and doubtless more would have fallen; but before they had been long thus engaged, an order was issued for them to desist. It came from Jan Van Dorn, who had just conceived a grand economic scheme, suggested by something he saw in the river. This was a hippopotamus, or rather several; for since leaving the foot of the rapids, numbers of these amphibia had been observed, some waddling about upon the banks, others swimming to and fro in the water, the cows with calves on their backs; still others at rest on the surface as if asleep, with white birds—a species of sea-gull—perched upon their shoulders. Even those moving about had each its quota of such perchers, now and then affording an amusing spectacle, as the unwieldy quadrupeds sank under water, forcing the birds to take wing with an odd air of bewilderment. Not so different was the behaviour of the quadrupeds themselves, as they saw the raft bear down upon them, and go drifting by—a sight altogether new to them. They may have seen canoes, water-horses, and other contrivances of river navigation in use among the natives, but never a craft like that—never one of such monstrous dimensions. And a monster it must have appeared to them, as at intervals it belched forth flame and smoke, accompanied by the loud reports of the roers.

With heads raised on high, the hippopotami responded to all this in loud snorts, groans, and bellowing, more in astonishment than alarm. There was also a tone of defiance in it which gratified the ear of the old jäger, making known to him that he was in a river where these animals had rarely, if ever, been hunted. This meant money, should the opportunity be taken advantage of, and he was not the man to let such a chance slip. Hence his having ordered the young Boers to cease firing at the birds, the zeekoes (Note 1) offering a mark better worth powder and ball. So, from that moment, not one was passed within shot-range but had a bullet lodged in its body, and a second if the first failed to kill it; sometimes a whole volley, when needed to make death sure. Rarely was there a call for such wholesale expenditure of ammunition. Most of them had slain zeekoes before, and knew the exact spot to aim at; that most vulnerable being midway between eye and ear. With marksmen skilled as they, misses were rare; and the crack of a gun might be taken as sounding the death-knell of a hippopotamus.

While engaged in this practice, they became witnesses of an odd spectacle afforded by an old bull, which had been fired at and hit just behind the ear, too far back to give him his death wound. It seemed but to drive him crazy; as he commenced spinning round and round on the water, as a sheep in a pasture field, attacked by the “turn giddies.” But he was not permitted to make many gyrations, ere a volley from the raft brought his spin to an abrupt termination, along with his life.

Thus, day after day, was slaughter made among the zeekoes, as the rafters went on down the river. Not wanton slaughter; but in pursuance of that scheme of economy the head baas had got into his head, now known, and approved of by his associates. How could they help approval, as they looked on a pile of hippopotamus teeth that lay on the raft’s deck, every hour growing bigger, each fresh pair added being as so much money put into their pockets?

All this was satisfactory enough, but nothing to what awaited them farther down. As they drew near the coast, they came upon an islet lying centrally in mid-stream, at a place where the river was more than a mile in width. They sighted it just before sunset; and, knowing the night would be moonless and pitch dark, it was determined to bring-to at the islet, and remain by it till morning. So the raft’s head was set for it, without much change of course, as they had been already bearing nearly straight down upon it. When near, they saw it was selvedged with tall reeds, of the kind called palmit, which, standing in the water, formed a belt all round it, interrupted only at the upper end, where an open list led into the firm dry land. It was a sort of natural canal, no doubt due to the water being there too deep for the palmits to get root. It was just wide enough to admit the raft; and without further ado this was run into it, and “docked.”
