The Colonel recognized the imperative necessity for yet one more effort, and whilst his companions, with almost superhuman energy, repulsed the natives, he re-entered the donjon. This donjon was formed of an intricate framework of dry wood, which would readily ignite by the application of a flame. The Colonel set it alight with the powder from the priming of his gun, and, rushing out, rejoined his companions. In a few moments, rolling their mitrailleuse before them, the Europeans, under a shower of arrows and various missiles, were descending the mountain, and, in their turn, driving back the natives with a deadly fire, reached the steamboat. The engineer, according to orders, had kept up the steam. The mooring was loosened, the screw set in motion, and the "Queen and Czar" advanced rapidly over the dark waters. They were shortly far enough out to see the summit of the mountain. The donjon was blazing like a beacon, and its light would be easily discerned from the peak of Volquiria. A resounding cheer of triumph from English and Russians greeted the bonfire they had left behind. Emery and Zorn would have no cause for complaint; they had exhibited the twinkling of a star, and had been answered by the glowing of a sun. CHAPTER XXII. HIDE AND SEEK. When daylight re-appeared, the vessel was nearing the northern shore of the lake. There was no trace of natives, consequently the Colonel and his companions, who had been ready armed, laid aside their guns as the "Queen and Czar" drew up in a little bay hollowed in the rocks. The bushman, Sir John, and one of the sailors set out at once to reconnoitre the neighbourhood. They could perceive no sign of Makololos, and fortunately they found game in abundance. Troops of antelopes grazed in the long grass and in the shelter of the thickets, and a number of aquatic birds frequented the shores of the lake. The hunters returned with ample provision, and the whole party could enjoy the savoury venison, a supply of which was now unlikely to fail them again.
