This parish is situated on rocks of the calcareous series, which are for the most part like those of Laneast; but where Trewen joins Alternun, bounded only by the small river Inney, some strata occur which deserve more particular notice. It has already been stated, that on the opposite side of this stream, a potstone or ollareous serpentine occurs; on the Trewen side a talcose schist first appears, which is followed by a calcareous schist, with its surface talcose and glossy, resembling the slate at Cotele on the Tamar. This slate gradually passes into a compact limestone, which is light-coloured and talcose, especially in such parts as come in contact with masses of hornstone diffused through the mass. This limestone is quarried and burnt on the spot, but after the selection of such portions as abound with calcareous spar.
TRURO.
HALS.
Truro is situate in the hundred of Powder, and hath upon the north Kenwen, east Clement’s, south an arm of Falmouth Harbour, where twice a day, upon spring tides, the sea makes its navigable flux and reflux to the walls, keys, and streets thereof.
In the Domesday Book 1087, this place was taxed under the appellations of Trewret and Treured, which shews that it then consisted of two privileged manors or jurisdictions, viz. the borough of Trewret and the manor of Treured,
