"Be silent, for Heaven's sake," exclaimed De Walden, who had hitherto repressed his emotion, but could now bear no more. "Blessed be His holy name, who has delivered His servant from torments, which are unendurable even in thought. Let us speak no further of them. How far, and in what direction, do you propose that we should proceed to-night?" "We fly towards Basuto country. Basutos and Bechuanas not friends, or Chuma send message for White Prophet to be given back to him." "The Basutos! Very good. I can speak their language, and they will very likely shelter us until we are rested sufficiently to travel to Cape Town. But the Basuto country lies at some distance, does it not?" "Yes, several days' journey. But when we have passed Koodoo's kloof, all safe." "Koodoo's kloof? What, on the Vaal river? The river is not passable there." "Ah, you not know. We pass all safe, so they not catch us." The missionary said no more. Kobo evidently knew what he was about, and there was very little chance of their escaping from their pursuers except through his help. By his skilful management they had probably secured several hours' start, but that was all. The Bechuanas would be sure to be on their track on the following day, and their swiftness of foot was proverbial even among the Kaffir tribes. He resolved to attend implicitly to Kobo's instructions, and a few words from him prevailed on the lads to do the same. They hurried on till the forenoon of the next day, and then rested only a few hours during the meridian heat, resuming their journey with a speed which taxed the boys' powers to the utmost, and against which they would have rebelled, if they had not been plainly told by their guide that their lives depended on the speed with which that and the following day's travel could be accomplished. Kobo allowed another halt shortly before midnight, and the lads were further refreshed by a bathe in a deep cavity in the rock where the rain water had collected, before setting out on the following morning. The character of the country they were traversing now became more pleasing, and seemed to promise abundant shade and plenty as they advanced. The landscape was varied by groves of palms and sycamores; and not unfrequently date trees and figs offered to the travellers their ripe and tempting fruit. The dark-foliaged moshoma was relieved by the yellow of the mimosa, and the lilac of the plumbago. Herds of antelopes, and occasionally graceful koodoos and elands, bounded by them, and little rivulets, evidently on their way to mingle with some large river, covered the ground with a carpet of verdure. "Vaal river near now," remarked Kobo, when they paused a little before moonrise on the evening of the second day. "White boys travel fast-- travel like men. Bechuanas not catch them."
