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. See Principles of Geology, by Charles Lyell. This parish measures 5,041 statute acres.

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. THE EDITOR. The greater part of the valleys in Cornwall having been long since streamed, exhibit little else than heaps of unsightly rubbish; instead of displaying, as in other districts, the most pleasing features of a country. The late Mr. Humphrey Mackworth Praed has, however, proved in the case of a valley at Lelant, that such deformities may be removed, and the meadows restored to their natural beauty, accompanied even by pecuniary advantage to the proprietor. But such improvements are greatly obstructed by an anomalous property called the right of bounds. MABE. HALS.
