The church is situated on very lofty ground, amidst granite rocks, so universally scattered over the surface, that many houses are built in such a manner as to make one or more of these rocks available in the walls. Yet the soil is good; and Mr. Grylls, the present vicar, has proved that taste and perseverance may create an elegant assemblage of whatever is useful or ornamental in a situation apparently the most unpromising. The tower as well as the church far exceed the average in size and beauty. The tower has a singular addition of a small room at the top; and in this room various records relating to the Stannaries and to the Duchy of Cornwall are said to have been preserved, while the armies on both sides, in the civil war, were ravaging the country, and destroying the towns.
Mr. Tonkin has remarked on the romantic and beautiful vale which descends from Luxilian Church by Prideaux to St. Blazey Bridge, and in explaining the phenomena of lofty and precipitous inland cliffs, he has anticipated the most recent theories of modern geology.

GEOLOGY, BY DR. BOASE.
This parish stretches north and south across the large patch of granite, which is situated between Bodmin and St. Austell, and also extends over the slate at its northern and southern extremities. The extent of surface covered by the northern slate is more than a square mile; but the southern slate forms only a small triangle north and north-east of St. Blazey Bridge. The northern half of this parish corresponds with the parish of St. Dennis in the nature of its rocks; the southern half with St. Austell and St. Blazey. The most interesting feature of this parish, in a geological point of view, consists of its numerous and extensive stream-works. This part of Cornwall, including the adjoining parishes, has long been celebrated for the fine quality of its stream-tin, which is, as to the greater part, either crystalline, or of the kind denominated wood-tin, on account of its fibrous texture. The gravel containing this stream-tin rests on the rock, or on its untransported debris; above this occurs a regular stratum of decayed trees and plants; in the deepest stream-works these are covered by another bed of gravel containing tin, having also a superincumbent layer of decayed trees and plants: but this second stratum of tin, always less in quantity than the first, is seldom of sufficient value to pay for the labour of separation. Over all occurs a layer of uncertain thickness, composed of the debris of adjacent rocks, and sustaining on its surface a coating of recent vegetable, and forming marshy, arable, or meadow land, according to the accidental situation of the spot.
