Trevedick, also Trevithick, words of one signification, id est, rustic or farmers’ town, is the dwelling of Nicholas Polamonter, Gent. (so called from Polla-monter in Newland.) TONKIN has not, again, any thing of the least importance different from Mr. Hals. THE EDITOR. Rialton is the object of highest importance in this parish. Its antiquities are not much known; but when Mr. Sidney Godolphin was created Earl of Godolphin, his son, who had married Henrietta Churchill, eldest daughter of the Duke of Marlborough, assumed the appellation of Lord Rialton, and Lady Rialton was one of the ladies of the bedchamber to Queen Anne. A small print is given of the south entrance gate still remaining, in C. S. Gilbert’s History of Cornwall, vol. ii. p. 673. The property belonged to the late Mr. Thomas Rawlings of Padstow, having probably been acquired when lands were sold by the duchy to redeem the land-tax, but it was alienated on his decease. New Quay, mentioned by Mr. Hals as a pretty safe road and anchorage for vessels, and also as a convenient place for establishing a fishery, is become a successful station for sea nets. In Lord Dunstanville’s edition of Carew, p. 357, it is stated, “The place was called New Quay, because in former times the neighbours attempted to supply the defects of nature by art, in making there a quay for the road of shipping, which conceit they still retain, although want of means in themselves or in the plan have left the effect in nubibus. The quay has now been many years constructed, but I apprehend it is not capable of receiving any other than small vessels.” This parish measures 4759 statute acres.

The parish feast, like that of St. Columb Major, is on the Sunday nearest to the 17th of November. GEOLOGY, BY DR. BOASE. On the eastern side adjoining to the Downs, the rocks are quartzose, but the greater part of this parish is composed of slates belonging to the calcareous series, which extend to the sea shore. At Tremper Bridge, and in the islands lying at the entrances of St. Columb Porth, beds of black limestone occur, associated with talc, schist, and blue slates. The most interesting feature, however, of this parish is the testaceous sandstone at New Quay, and on the shores of Fistral Bay. The land adjacent to the sea at those places is covered with sand, which above high-water mark is lapidified, as is also a bed of pebbles on which the sand sometimes rests. For the particulars of this phenomenon the first and the fourth volumes of the Cornwall Geological Transactions may be consulted. CONSTANTINE. HALS.
