That night Engelbrecht and his Hottentot slept among some bush on the mountain side, within three hundred yards of the English camp. They had well calculated the movements of the gold-seekers and their native servants guarding the camp, and had determined to hazard the descent by the rope-ladder at about two hours after sunrise next morning. By that time, they reckoned, the party down the kloof would have quitted their resting-place and gone off for the head of the valley, where their operations now lay. Three of the servants in the camp would probably be away--so Quasip, from his previous spying operations, reckoned it out--with the oxen and horses, grazing far down the hill. Jan Kokerboom would most likely be alone at the wagon. If they could avoid his scrutiny, as they hoped to be able to do, they could descend the ladder and conceal themselves without difficulty in the kloof below. In the afternoon, as the diggers returned to their sleeping-place, they could be easily ambuscaded. Some dangers there might be--dangers which had been pointed out to his master by Quasip; but in the mind of the Boer, thirsting as he was for revenge at any price, these were as naught compared with the chances of success. At dawn the pair of ruffians descended very softly from their place of concealment, and letting themselves down the steep declivity with the greatest care and caution, by means of bushes and stunted olive-wood trees, which lent them invaluable aid, safely accomplished their purpose. Now, seeking the centre of a clump of high bush close to the cliff edge, they lay within a hundred and fifty yards of the ladder, and about two hundred yards from the camp, from which they were still completely screened. Two hours went by. Surely by this time the coast must be nearly clear, and their attempt might be made? With extreme caution Engelbrecht raised himself from his hiding-place, and, peering through the bushes, looked down into the kloof. Far away, up near the head of the valley, he could discern two or three men, their figures dwarfed by the distance, at work. That was right enough. Now for the attempt on the ladder.
