THE GEOLOGY, BY DR. BOASE. The geology of this parish is precisely similar to that of the adjacent parish of St. Clether. The northern part is situated on that range of downs which extends from Launceston to the British Channel. These downs consist principally of varieties of dunstone, which are sometimes felspathic; but in general they are very siliceous, and even quartzoze. They are interesting in an economical point of view, as containing extensive deposits of the ores of manganese. A mine of this substance has been long worked at Letcot in Laneast. The ores occur in a lode or cross course of capel, running north-east and south-west; the lode is about twelve fathoms in width, and is composed of siliceous materials, or rather varieties of compact felspar, in which silex greatly predominates. The ore is arranged throughout the substances of the lode in veins and branches. In the latter form it was originally discovered, not many feet below the surface, and in such abundance that it was obtained at a very trifling cost, for the hardness and tenacity of the capel permitted the ore to be followed in all its ramifications without needing support: and the result of these operations has been to produce a large chasm, with curiously irregular and indented sides. LANHIDROCK. HALS. The manuscript relating to this parish is lost. TONKIN. Lanhidrock is in the hundred of Pider; hath to the west Lanivet; to the north Bodmin; to the east Fowey river, between it and St. Winnow; to the south, Lanlivery. This parish takes its name from St. Hidrock, and is the church of St. Hidrock. This probably may be the manor that in Domesday is called the Lanredock; and if so, it is one of the manors given by William the Conqueror to Robert Earl of Morton, with the Earldom of Cornwall. In the year sixteen hundred and ―――― John Lord Robarts, being disgusted on some occasion or other with the town of Truro, left his barony-house there, and new built a large one in this place, quadrangularwise, to which he added afterwards a noble gate-house, and enclosed a very handsome park, well-wooded, and watered by the river Fowey.
