Karl, who was hand and glove with these men, whom he had often himself led on commando, had no great difficulty in persuading some of them to accompany him on a fresh expedition of plunder. He held out high inducement in the shape of gold, which, it was known, the Englishmen were in search of; and the plan of inflicting revenge and humiliation on men of that accursed nation had, in addition, no small weight with the British-hating filibusters. Eight stalwart Boers, then, with two wagons and a number of well-armed native servants, signified their intention of aiding Karl Engelbrecht in his new campaign, and sharing the rich booty which they counted on lifting from the Englishmen. Halting for a few days to rest and recruit their trek oxen and horses, the party returned upon Engelbrecht's wagon spoor, and presently found themselves at the place where the Englishmen had last been sighted.

It was not difficult to hit off the wagon spoor of the gold-seekers' party; and now, eager to come to grips with their opponents, of whom they counted on making an easy prey, the Boers presently came in sight of the mountains wherein the Englishmen were so busily engaged in gathering the fortune that lay awaiting them.

Halting at this point, Engelbrecht with one of his Boer allies had ridden into the valley and convinced himself that here, at last, he had run the hated Englishmen to ground. Somewhere in these rude hills his foes were at work. It would be his business to trace them to their gold deposits, to locate accurately their camp, and then, descending upon them some morning at early dawn, attack them in such overwhelming force as to effectually beat down all opposition. Revenge--a bloody revenge, Karl meant it to be--was within his grasp; and gold--plenty of it, captured from his enemies--would, he firmly believed, make a man of him for the remainder of his life.

Already Karl saw himself back in the good Transvaal country, the owner of some of the richest farms in Marico, with a great, a palatial, farmstead of his own, surrounded by vast flocks and herds, and a wielder of much power in the national Volksraad. Why, indeed--his broad chest dilated as he thought of it--should he not aspire to like power and prominence with Paul Kruger himself! Paul was growing old; in a few years his course would be run, and some strong man would be needed to take his place. Thus dreamed Karl Engelbrecht, as he rode back to his wagon that day after spooring his adversaries to their mountain retreat, where, as he rightly calculated, they had been now some weeks at work in their hunt for gold.

Karl, after consultation with Antonio Minho, had soon laid his plans. That afternoon he dispatched his most trusted spy--a Hottentot man, Quasip by name--to spend a couple of days in exploring the interior of the mountain and spying out the land. Quasip was to keep off the wagon track, to creep about quietly, and to find out exactly what the Englishmen were doing and where their camp lay.

Quasip returned at the end of two days and nights, having perfectly accomplished his mission. He had located the English camp, observed its situation and defensive advantages, peered over into the Gold Kloof, noted the rope-ladder, and also the pile which the Englishmen had accumulated, without attracting the notice or suspicion of those within the camp. The Hottentot had entered the valley and made himself acquainted with the Gold Kloof before Mr. Blakeney's boy Seleti had discovered the approach of the Boers; and he had been able to accomplish his mission and make his report to his master without detection--a clear gain for Karl Engelbrecht and his party.

But Poeskop meanwhile, on his part, had been by no means idle. He had located the freebooters' camp, and ascertained the strength of the Boers and their men. Returning from his expedition, and wandering, as he always did, hither and thither in search of any spoor or sign that might tell of danger, he had encountered a footprint that was unknown to him: a spy had entered the valley since the two horsemen reported by Seleti had ridden in. Poeskop spoored the Hottentot's tracks to the vicinity of his master's camp, and satisfied himself that his rival--for he saw at once that he had a rival, and a very clever one--had made himself acquainted with all their doings. He had, in fact, convinced himself that now indeed danger threatened speedily. Returning to camp, he made his report on the very afternoon on which Quasip the Hottentot had told his own master of his discoveries. Both spies had accomplished their tasks to admiration: neither had encountered the other. Yet Poeskop had scored, inasmuch as he knew what the Boer spy knew; while the Hottentot and his master were ignorant, thus far, that they themselves had been spied upon.

Poeskop entered the camp, and at once unburdened himself of his information. Mr. Blakeney was scarcely surprised. He was anticipating attack, and had long since taken means to repel it. But it was a serious matter to know that eight fresh Boers--men who could shoot, and were thoroughly used to veldt fighting--were now with Karl Engelbrecht. These, with Karl himself and Minho, would raise the white attacking force to ten men. Add to this some six or seven natives, who could shoot more or less well, and it was clear that the little garrison above the Gold Kloof would have to confront almost overwhelming odds.

Still their situation was a very strong one. Any assault made upon them must be delivered from the front. Already, behind the thick and impenetrable fence of thorns, they had raised stone breastworks, through or over which they could shoot while they themselves were almost perfectly concealed. Their water supply was just behind them; and for food, if the siege should last more than a day or two, which was very improbable, they must sacrifice one of their spare oxen. As for arms, they possessed enough to furnish six of their whole party with two rifles apiece; two others would each have a rifle. There remained one over, which would bring up their total weapons of defence to fifteen. To these might be added four shot-guns, which, loaded with buckshot and used at close quarters, would be of sensible assistance.

Poeskop, after a night's rest, was again dispatched on a journey of investigation. The little Bushman was now thoroughly in his element. He craved excitement, of which hunting and warfare represented to him the highest forms; and he craved, and saw with prophetic eyes, revenge--a final revenge--upon Karl Engelbrecht. He returned the same night with serious news. The Boers had quitted their camp that afternoon, and, leaving a sufficient guard to look after the wagons, had ridden into the mountain. With them were six native servants, carrying rifles. They were now resting in some thick bush at the commencement of the first valley, about six miles away.
