and hardened and thrown into parallel irregular folds, and that these rocks were afterwards worn down by the action of water, at a time when the land was still beneath the ocean, with the result that many basin-shaped depressions are preserved and exposed, each of which holds a certain amount of water. Just as we never dream of putting down a well in this country without knowing the positions of the water-bearing strata, so it is hopeless to bore profitably for water in the Colony till the districts are defined over which the water-bearing basins are spread. Nothing arrests the escape of water in its course through the rocks more efficiently than intrusive sheets of igneous rock which rise to the surface, but until the distribution of these dykes is systematically recorded it will not be possible to open out all the water which is preserved underground. There is no doubt that by utilising geological facts of this nature, a better water supply may be obtained, which will enable more land to be brought under cultivation, and larger crops to be raised. I may say that the Colonial Government is fully aware of the importance of following out such lines of work, and steps are being taken to give effect to such exploration. Vegetation, however, by its radiating power, must always be one of the chief aids to improved water supply. In the matter of mineral wealth, Cape Colony is not so rich as some adjacent lands. It contains coal, but the individual beds of coal are thin, and owing to this thinness the coal necessarily alternates with shale, which is more conspicuous than in the coal fields of Britain. I remember that Professor Sedgwick, my old master in geology, told me that in his youth seams of coal only some four to six inches thick were worked on the sides of hills in Yorkshire, and that the coal was carried on horseback over the country to supply the wants of the mountain population. Cape Colony is in a far better state than that. In the Eastern Province the beds of coal are frequently a foot or two or more in thickness. They crop out on the surface with a slight dip near to the railway, and although only worked at present in a few pits (as at Cyphergat, Fairview, Molteno--I did not visit the Indwe)--the coal-bearing rocks certainly extend over a much
