Whilst Grenville collected the powder, Kenyon promptly set out in pursuit of the slaver, but could find no trace of his whereabouts. The fellow’s claws were, however, cut for the nonce, as there was blood upon the rock where he had been standing, and his rifle was still lying there, the hammer having been cut clean away by Grenville’s bullet. So that wounded, unarmed, and unsupported, it was a shrewd count that they would easily get him when daylight came, and get him they must, for he clearly was a dangerous, as well as a very slippery, villain.

Our friends soon succeeded in blowing up the rock, and preparing a new outlet for the water, and this was not accomplished any too soon, as by the time they had collected the arms, which were everywhere strewed about the confined field of battle, the water was already lapping gently against the upper edges of the steep ascent, and in another ten minutes it was racing down the track, and shooting clear over the beetling wall of rock, thus returning to its own natural bed in the shape of a magnificent waterfall, whose enormous volume, as it fell, waked a mighty echo, which would henceforward cause a perpetual and thundering murmur amongst the rocky glens of the mountains, as if nature were herself complaining of this irremediable mischief, wrought by the puny hand of careless and unthinking man.

Hardly had Grenville and Kenyon regained the mountain side, than the report of firearms was heard away across the veldt, and the quick flashes of Leigh’s repeating-rifle could be distinctly seen. In a few short minutes all was again as quiet as death, and the twain looked anxiously at one another, yearning to know with whom the victory rested, when all at once, through the still night air, and right across the rolling veldt was wafted the wild war-cry of the children of the Undi, proclaiming the successful accomplishment of another act of retribution, and the absolutely triumphant success of Amaxosa’s daring scheme for the destruction of the foe—a success which was marred only by the single detail of the temporary escape from their vengeance, of the Slaver-Chief himself.

Grenville and Kenyon next lighted a large fire to apprise the detachment out upon the veldt, of the exact position of the party upon the mountain side; and this having been done, Kenyon, who never travelled without a complete surgeon’s “kit,” proceeded to attend to the injuries of the wounded men, and soon had the poor fellows as comfortable as circumstances permitted.

Shortly after this, the Zulu, Umbulanzi, in charge of the “water department,” and to whom belonged no small share of the credit of this successful affair, made his appearance, accompanied by all but two of the Zanzibaris, who, under his direction, had acted in the capacity of sappers.

It seemed that Amaxosa had fortunately foreseen the possibility of this detachment hitting upon a bed of rock, and thus having their work stopped, and the whole scheme completely ruined, and he had, therefore, supplied his confrère with a 56 pound keg of powder out of Leigh’s ample stores, and finding that a great slab of broken ironstone rock was spoiling his little game, this Zulu had coolly slapped the whole keg under the edge of this obstruction, and blown the entire affair sky-high, and along with it two of the Zanzibaris, whose unfortunate curiosity had prevailed over their accustomed discretion.

“Haow Inkoos,” he said, speaking rapidly to Grenville in the Zulu tongue, “it was indeed a very great sight, and never will Umbulanzi see the like again. The rock shot up to the heavens on high, and with it went the low black fellows. The great stone came down again, my father; but, though I waited long for the low fellows, they came not, and as the cowards must have run away for good, Umbulanzi did not stay.”

The moon was waning fast, but the stars still held the curtains of night over the wide-stretched whispering veldt, when the victorious party of Amaxosa, accompanied by the slave-gang, was heard approaching from the north, and upon their arrival it was found that the little band had not suffered further in any way, having satisfactorily “rushed” the remaining slavers, and disposed of them every one.

The anger of Leigh and Amaxosa, however, knew no bounds when the cunning escape of the arch-enemy was made known to them, and both bitterly repented that they had not made sure of the fox by knocking him on the head, and registered a solemn vow to commit no further mistakes of the kind, should Zero fall into their hands again. Clearly, however, nothing could be done until dawn of day, and it was decided, therefore, to let the rescued slaves sleep in their irons, and to wait for daylight, in order that their captors might gain some little insight into the character of their new charges. So, having set a watch of Zanzibaris, overlooked by Grenville himself, the tired army laid itself down, and was soon fast asleep, whilst the rescued slaves, who had been told the good news that they would be liberated in the morning, chattered to one another throughout the livelong night, like a troop of monkeys in the forest. With the first gleam of daylight, Leigh and Amaxosa were afoot, and without even staying to dispatch a mouthful of food, threw themselves upon the bloodstained trail of the Slaver-Chief, and were almost instantly lost to sight amongst the dense fog-banks which overhung the surrounding veldt in every direction.
