“A vallum, or terrace, separates this wall from another of considerable strength and thickness, being thirteen feet across at the top. The circular area inclosed by this wall is two hundred and fifty-four feet in diameter. A third wall, of no great substance or height, like the others, appears to have made a circuit within this space, and reduced the diameter to one hundred and ninety feet. But what is most curious in this Castle, is the appearance of a certain wavy outline, slightly raised above the natural soil, but overgrown with turf. The singular form of these foundations, if they are supposed to be the inclosures noticed by Borlase, and their exact regularity, which I took some pains to ascertain, is perhaps deserving the attention of some more experienced antiquary. “The area within is very uneven, and has, nearly in the centre, a small round inclosure, twenty-two feet in diameter, without an entrance. It is exactly similar in its construction to the remains in Caër-Brane and Bartìnè Castles. There is a well also within the circuit of the walls, and we were told it was never known to be without water. The diameter of the whole work, from ditch to ditch, north and south, is four hundred and thirty-six feet.” Rosevithney was for ages a gentleman’s residence. The family of Larmer possessed it during a considerable time, till it passed by an heiress to a branch of the Davieses. The freehold has recently been sold three or four times. Trowell, an adjoining farm, which belonged to the Godolphins, is remarkable for the extremely productive copper-mine, called Whele Fortune, which first launched Mr. Lemon on his splendid voyage through life. The name of another farm in Ludgean, which cannot be accidental, requires notice. On this farm was a well, now destroyed by mines, having, in all probability, some slight quality of a chalybeate. The water acquired an established reputation for the relief of weak sight, and hundreds repaired there every year to bathe their eyes. The farm is named Collurian, and has been so time out of mind. Varfull has been held as a leasehold for lives, or under copy of court roll, for more than a century, by the family of Davy, and actually belonged to Sir Humphry Davy, whose name has reflected so much honour, not on Cornwall alone, but on the whole nation to which he belonged.
