The Tendukaira mines are situated in a more westwardly position of the same valley, as those of Jabalpur, and are about one mile and a half distant from the village Tendukaira; they are near a low range of hills composed of *stratified quartz rock* which evidently contains felspar, and this rock is the gangue (No.1) of the ore; at times it assumes the character of *hornstone*, and when contiguous to the ore, it is penetrated by numerous slender veins, which although filled with the oxide of iron are very different from ordinary dendritic appearances, as they are always in shoots, intersecting each other, and never arborescent, and it seems quite impossible that they could have been produced by infiltration.
