The column swung out into the great dry Karoo prairie. It was a comfortless trek. Earth and sky seemed to have forgotten the rain of preceding days; or it may have been that the storms which had distressed us had been purely local, for we had struck a great waterless plain which showed not the slightest sign of moisture. The shuffling mules and lumbering waggons churned up a pungent dust; a great spiral pillar of brown cloud mushroomed out above the column; no breath of air gave relief from the vertical rigour of the sun; the great snake-like column sweated and panted across the open, reporting its presence to every keen-sighted Dutchman within a radius of fifteen miles. We have seen the beauties of the Karoo; but we cannot blind ourselves to its defects, for they are the more numerous. At its best it is a great stagnant desert, studded here and there with some redeeming oases. Its verdure smacks of the wilderness. Stunted brown and grey, the heather from which these rolling steppes take their name is stranger to the more clement tinge of green, which is the sign of a soil less sapless. Yet a peculiar fascination militates against a general condemnation of the pitiless Karoo. One cannot altogether banish from one's mind the memories of a summer night upon those wastes.
