Advent contains the small villages of Treclogoe or Trelogoe, Pencarow, and Tresinny. Most of the estates in this parish are parcel of the duchy of Cornwall, being held as free and customary lands of the manor of Helston in Trigg. The manor of Trelagoe, Treclegoe, or Trenelgoe, after having been for some descents in the family of Phillipps, was bequeathed by the late Rev. William Phillipps, Rector of Lanteglos and Advent, to his nephew John Phillipps Carpenter, of Tavistock, Esq. whose son is the present proprietor. THE EDITOR. Advent contains 2,844 statute acres.

GEOLOGY, BY DR. BOASE. The eastern part of this parish consists of granite, forming a portion of an extensive group of this rock, in which are situated Roughtor and Brown Willy, the highest hills in Cornwall. This granite is of the ordinary kind, large grained, and often porphyritic. It contains beds of fine-grained rocks, in some of which crystalline felspar, quartz, and mica, constitute the entire mass; but in others these minerals are embedded in a basis of compact, or rather of granular felspar, which is itself apparently a compound of felspar and quartz. The junction of the granite with slate is concealed by a large track of marsh and bog; adjoining to which is a dreary waste of common, resting on an irregular bed of quartzose gravel, derived from the granite hills, and evidently of diluvial origin. This eastern part is sterile, merely affording a scanty subsistence to cattle during the summer. The remainder of the parish is composed of felspar and hornblend rocks, traversed here and there by courses of granitic elvan, a rock in every respect similar to that occurring in the granite. One of these courses may be seen by the road side near the rivulet of Pencarrow. Here the country is wooded and cultivated, exhibiting some picturesque scenes of hill and dale; so characteristic of the hornblend rock near granite.
