The tract is an extensive one, probably upwards of 50,000 square miles lie within its limits. It is bounded on the north by the Gariep or Orange River--but as that flows and eddies at the bottom of a tremendous gorge which is cut off from the plains by a lofty, stark range of mountains,--coal-black in colour for their greater extent and glowing hot throughout the long, cloudless day, the traveller seldom sees it. The western boundary is the Atlantic Ocean; the eastern an imaginary line drawn approximately south from the Great Aughrabies Falls to the Kat Kop Range. If we bisect this line with another drawn due east from the coast to the Lange Berg, we shall get a sufficiently recognisable boundary on the south. From the tract so defined must be deducted the small area surrounding the Copper Mines, and a narrow strip of mountain land running parallel with, and about sixty miles from the coast. This strip is sparsely inhabited by European farmers. The occasional traversing of this vast tract lay within the scope of my official duties. My invariable travelling companion was Field Cornet Andries Esterhuizen (of whom more anon) and a small retinue of police, drivers, and after-riders. We never escaped hardship; the sun scorched fiercely and the sand over which we tramped was often hot enough to cook an egg in. Water, excepting the supply we carried with us, was as a rule unobtainable; consequently we had to eschew washing completely. We often had to travel by night so as to spare the oxen, and as the water-casks usually almost filled the wagon, we then had to tramp, vainly longing for sleep, through long, weary hours, from sunset to sunrise. And after the sun had arisen the heat, as a rule, made sleep impossible. It was to the more inaccessible--and therefore comparatively inviolate-- expanses of this wilderness that I was always tempted to penetrate. Therein were to be found a scanty flora and a fauna--each unusual and distinctive,--composed of hardy organisms, which an apprenticeship from days unthinkably ancient had habituated to their most difficult conditions of existence. If, somewhere near the margin of the great central plain, we happened to cross the track of a vagrant thunderstorm, we would see myriads of delicately-petalled blossoms miraculously surviving, like the Faithful Rulers of Babylon in the Fiery Furnace. On the flank of some flaming sand-dune we would find the tulip-like blooms of the Gethyllis flourishing in leafless splendour. Their corollas were of crystalline white splashed with vivid crimson; deep in each goblet lay the clustered anthers,--a convoluted mass of glowing gold. Is this flower a grail, bearing beauty too ineffable to die, through an arid aeon from one cycle of fertility to another?
