The northern part of this parish rests on the porphyritic series, but no where reaches the granite hills: its rocks are very felspathic and metalliferous. The southern part comes into the calcareous series, and its rocks are like those of Creed, Cuby, and Cornelly; the most interesting of these rocks may be seen on the hill to the westward of Grampound. They appear to afford a most decided example of greywacke, exhibiting large grains, and even nodules of quartz on their fractured surfaces; this however can only be seen on surfaces that have been for some time exposed to the weather; for no such appearance can be observed when the fractures are recent and perfect. These rocks are probably masses of compact felspar, in the bases of which silica so predominated at the time of their formation, as to have given rise to large concretions of quartz. * * * * * Since Doctor Boase made the geological examination of Cornwall, an abridgment of which he has had the kindness and the liberality to communicate for this work, the road leading westward from Grampound, has been turned to the north, and thus obviated a steep and even dangerous hill, and in consequence the sections referred to can no longer be seen on the highway.

In anno 1291, 20 Edward I. (Tax. Benef.) this church was valued at one hundred shillings, being then appropriated to the Abbey of Tavistock. This is a vicarage, valued in the King’s Book, £15. 11_s._ 0_d._; the patronage in the Bishop of Exeter; the incumbent Mr. Daniel Bawdry, rector also of Worlegan. THE EDITOR. Mr. Lysons says that the ancient name of this parish was Cruetheke; it is commonly pronounced Quithik. The greater part of this parish belongs to Mr. Coryton of Pentillie. Mr. Lysons gives a detail of the manors, but it is quite uninteresting. One called the manor of Trehunsey, probably gives a name to the principal village, Trehunest. The church has on the outside an appearance of very great antiquity verging on decay. Within, it contains several remnants of ancient times, and monuments with inscriptions to the memory of former parishioners. The great tithes were appropriated to a chantry at Haccomb, in the Deanery of Kenn, in Devonshire. Tanner says, in the church of St. Blase here was a college or large chantry of five priests, under the government of an archpresbyter in the reign of King Edward the Third. Dugdale’s Monasticon, new edition, has the following history of this place.
