There is not, however, a striking resemblance in the geological structure of the opposite shores of Cape Breton and Nova Scotia; but this is no uncommon circumstance in nature; and we often, in America, meet with a chain of granite predominating on one side of a river, and a calcarious region prevailing on the other. The geology and mineralogy of Cape Breton, can only be said to be known in outline. From all that I have observed, however, and from all the information I have been able to obtain, I may remark, that almost all the rocks named in the discordant nomenclature of Werner, are found in this island. Among the primitive rocks, granite prevails in the peninsular country south-east of the Bras d'Or; and it probably forms the nucleus of the Highlands between this inlet and the Gulf of St Lawrence. Sienite, trap, mica, clayslate, and occasionally quartz, also appear on the Gulf coast. Primitive trap, sienite, mica-slate, and clayslate, show themselves, together with transition limestone, greywacke, gypsum, and coal, generally in all parts of the island. The class of floetz rocks appears, however, to be the most numerous; and coal exists in such abundance, that persons unacquainted with geology have stated seriously to me that they considered this mineral formed the base of the whole island. Coal, in a field, or fields, of vast extent, abounds in the southeastern division of the island, surrounded by carboniferous limestone, new red sandstone, &c. The quality of this coal is excellently adapted for common fire-places. The extent or quality of the coal fields north of the Bras d'Or, have not been ascertained. Gypsum occurs in great plenty along the shores of the Bras d'Or, at the Gut of Canseau, on the Gulf...
