The colony of Natal; an official illustrated handbook and railway guide . from the sea, there lies upon the southern slope of thegranite belt a vast mass of white, highly crystalline marble. Itis for the most part of a pure tint, but sometimes is tinged witha green, pink, or yellowish colour. There is no distinct stratifi-cation, it being separated into large masses by laminae of gneissand granite, which contain a considerable percentage of quartz. It is perfectly clear that the great central axis of granite 50 has been upheaved, subsequent to the deposit of the neigh-bouring beds of rocks, many of which are broken, tilted upby it, and, when in its immediate proximity, changed in theirmineral character. The sandstones of Natal occur mainly in thick lujrizontalbeds, alternating with shale of various descriptions. Theyare to be found up to the highest part of the sub-terrace ofthe Berg, , about 7,000 feet above the sea, and on the coastto the north of the granite belt. The flat-topped mountains andhills, which form such familiar features in the scenery of. KRANTZ KLOOF FORMATIONS. Natal, are composed of vast horizontal layers of this stone,reared up sometimes on sloping buttresses, and looking, asMr. Henry ]5rooks says, like broken slabs of the oldpavement that was shattered by the earthquake throes on theupheaval of the granite. The rivers of the coast, while not infrequcnth flowingthrough the stratified rocks to the granite beneath, often pass 51 between picturesque cliffs of reddish sandstone, some of whichmost probably belong to the Devonian and Silurian systems,and some to the younger age of the new red , again, are associated with alternating layers of grittysandstone, which unquestionably is of the carboniferous of greenstone-trap constantly pierce the sandstoneformations, while faults are frequent. Coal occurs in Natal amongst the carboniferous sandstonesin various places, and, fortunately for the Colon), is abundant. Mr. Etheridg
