This extensive parish resembles that of Camborne in its geological structure. Its southern portion rests on granite, which at Carnarthen abounds in shorl; and at Carnkie it contains a bed of porphyry, with crystals of felspar and of shorl; and at the same place another bed, the basis of which more resembles compact shorl rock than it does compact felspar. Near Portreath, and from thence to Perth Towan, the slate appears to differ from that of Camborne; and at Perth Towan it contains short irregular veins of calcareous spar, as at Porthalla in St. Kevern, and at other places on the borders of the calcareous series. ST. JOHN’S. HALS. Is situate in the hundred of East, and hath upon the north Anthony, east Maker, west Sheviock, south the British channel. The modern name John is derived from the tutelar guardian and patron of the Church, St. John the Evangelist. In the Domesday tax this parish was rated under the district or manor of Makertone. In the Inquisition into the value of Cornish benefices, made by the Bishops of Lincoln and Winchester 1294, Ecclesia Sancti Johannis, in decanatu de Eastwellshire, is valued xl_s._ viii_d._ In Wolsey’s Inquisition 12_l._ 4_s._ 4_d._; the patronage in ――――, the incumbent Tarr. The parish is rated to the 4_s._ per pound Land Tax 1696, 72_l._ 0_s._ 8_d._ TONKIN. The manor of Insworth, A Peninsula on whose neck, says Mr. Carew, standeth an ancient house of the Champernons; and descended by his daughters and heirs to Fortescue, Monck, and Trevilian, three gentlemen of Devon. The site is naturally both pleasant and profitable; to which the owner, by his ingenious experiments, daily addeth an artificial surplusage. Mr. Tonkin then adds, this estate (as I am better informed) being in the parish of Maker, I shall there treat more fully of it. Sir Richard Champernon, of Madberie in Devon, Knt. had by Catherine his wife, daughter of Ralph Daubeney, Knt. two sons, Richard and John. He died in 1418, and gave this place to the said John, who lived here, and left only one son, a Richard Champernon, who by his wife, the daughter and heir of Sir John Hamley, Knt. left three daughters, one of whom married Humphrey Monck, of Potheridge in Devon, Esq. The said Sir John Champernon was Sheriff of Cornwall 24 Henry VI. 1445, as his son Richard in the first year of Edward IV. 1461. THE EDITOR. Mr. Hals has not gone into any particulars respecting this parish; but he has occupied several pages with the real and with the legendary histories of the Evangelist, to whom the Church is dedicated; these are omitted as unsuited to a local history.
