This fortified ground I examined in August 1792. It is an earthwork denominated Warren, containing six Cornish acres, as the farmer told me, or about seven statute acres. It has a high and broad rampart twelve or fourteen feet high, and a deep ditch fourteen or sixteen feet wide. The whole forms a long square, the greatest length from east to west. It has two gateways on the north, and two on the south, one on the east, and one on the west, each answering to the other, and having a raised avenue across the ditch. I therefore conclude it to be a Roman camp, made at the period when that people subdued Cornwall, and calculated for the reception of a large detachment. The revetments mentioned by Dr. Borlase do not appear, nor the projecting turrets. About a mile to the north of this, beyond a deep gully, may be found what is noticed by Mr. Tonkin as Caer Voza, and noticed by Doctor Borlase in his Natural History, p. 324, as Caerfos or Caerfosou. This is an estate, called so from a field close to the house, which has a strong and lofty rampart upon the north side, and a large deep ditch upon the north of that. These continue all along the northern side of the field, and have a slight return on the east and west towards the south; but then they cease, nor can any traces be found of them afterwards. Perhaps this imperfect work may have been a camp of the Britons opposed to that of the Romans, or one commenced at least for that purpose. Thus far Mr. Whitaker. * * * * * Trehane, with a considerable property around it, were given, as Mr. Tonkin has stated, by the last Mr. Williams of that place, to his eldest daughter Mary, who married the Rev. William Stackhouse, D.D. Rector of St. Erme, the adjoining parish. Doctor Stackhouse was from the county of Durham, a brother of the Rev. Thomas Stackhouse, Vicar of Beenham, Berks, well known by his learned works. A complete body of Divinity――A fair statement of the controversy between Mr. Woolston and his adversaries,――and various others; but above all by an History of the Bible from the beginning of the World to the establishment of Christianity, in two volumes folio, first printed in 1732, a work that has gone through various editions, and may be found in every good library. Doctor Stackhouse left two sons, William and John. His eldest son William, married one of the Miss Rashleighs of Menabilly, and settled at Trehane, where he lived universally esteemed and respected till June 1830, when he departed this life in his 90th year, leaving Trehane to his eldest son, who resides there at present. Mr. John Stackhouse, whose son Edward William Wynne Pendarves represents the county in Parliament, is noticed under Cambourne. TREWITHAN.
