Thenceforward Eddo, Pani, and Hana hid their judgments from Rachel, and would not suffer such suppliants to approach the camp. Also when they seized a number of men because these had conspired together to rebel against the Ghost-people, and brought them on towards their own country for a certain purpose, they forced them to act as bearers like the others, so that Rachel might not guess their doom. For now, with all their power, they also were afraid of this white Inkosazana, as Dingaan had been afraid. So they travelled up this endless slope of fertile land, leaving all the kraals of the giant Umkulus behind them, and one morning at the dawn camped upon the edge of a terrible desert; a place of dry sands and sun-blasted rocks, that looked like the bottom of a drained ocean, where nothing lived save the fire lizards and certain venomous snakes that buried themselves in the sand, all except their heads, and only crawled out at night. After the people of the Umkulus this horrible waste was the great defence of the Ghost-kings, whose country it ringed about, since none could pass it without guides and water. Indeed, Noie had been forced to stay here for days with her escort, until the Mother of the Trees, learning of her coming in some strange fashion, had sent priests and guards to bring her to her land. But the Zulus who were with her they did not bring, except one witch-doctor to bear witness to her words. These they left among the Umkulus till she should return, nor were those Zulus sorry who had already heard enough of the magic of the Ghost-kings, and feared to come face to face with them. But it is true that they also feared the Umkulus, whom, because of their great size and the fierceness of their air, the Zulus took to be evil spirits, though if this were so, they could not understand why they should obey a handful of grey dwarfs who lived far from them beyond the desert. Still these Umkulus did them no harm, for on her return Noie found them all safe and well. That afternoon Rachel and the dwarfs plunged into the dreadful wilderness, heading straight for the ball of the sinking sun. Here, although she wished to do so, she was not allowed to walk, for fear lest the serpents should bite her, said Eddo, but must journey in the litter with Noie. So they entered it, and were borne forward at a great pace, the bearers travelling at a run, and being often changed. Also many other bearers came with them, and on the shoulders of each of them was strapped a hide bag of water. Of this they soon discovered the reason, for the sand of that wilderness was white with salt; the air also seemed to be full of salt, so that the thirst of those who travelled there was sharp and constant, and if it could not be satisfied they died.
