GEOLOGY, BY DOCTOR BOASE.
A continuation of the granite of Blisland and St. Breward forms the north-eastern corner of this parish. A belt then succeeds, which appears to be of the same kind as the micaceous slate of St. Breward already described; it may be traced along the side of the Leskeard road in a disintegrated state. On leaving this road and proceeding towards the church, the rock becomes more argillaceous, as round Bodmin, and the land improves in quality. The western and southern parts of the parish consist of barren downs, reposing on rocks which abound in quartz.
St. Cleer is situate in the hundred of West, and hath upon the north, Altarnun; south, Liskeard; east, St. Tew; west, St. Neot. The modern name of this parish was not extant at the time of the Norman Conquest, but probably then passed in the Domesday tax under the titles of Trelven, Niveton, or Trethac. At the time of the Pope's inquisition into the value of Cornish benefices, in order to his Annats, 1294, Ecclesia de Sancto Claro, in Decanatu de Westwellshire, was charged ten marks; Vicar ejusdem 40s. In Wolsey's Inquisition, 1521, and Valor Beneficiorum, 19l. 16s. 8d. and the parish rated to the 4s. per pound Land Tax, l696, 241l. 17s.
The name of this parish is taken from the church, and the church's name from the titular guardianess thereof, to whom the same is dedicated, viz. St. Clare
