BOSSINEY-with-TREVENA, a borough and market-town in the parish of TINTAGELL, hundred of LESNEWTH, county of CORNWALL, 18 miles (W. by N.) from Launceston, and 231 (W. by S.) from London. The population is returned with the parish. This borough, comprising two villages, about a quarter of a mile distantfrom each other, is situated on a bleak and rugged part of the northern coast. The market is on Thursday; and the fair, which is held at Trevena, is on the first Monday after October 19th. Bossiney was made a free borough in the reign of Henry III., by Richard, Earl of Cornwall, brother to that monarch, but it never had a royal charter. A mayor, whose office is merely nominal, is chosen annually by a jury of burgesses empannelled by his predecessor, at the court leet held in October, when constables and other inferior officers are also appointed; the burgesses are chosen in a similar manner, as vacancies occur. The freedom of the borough descends to the eldest son of a burgess possessing freehold property within it, and is obtained by presentation of the jury. The elective franchise was conferred in the 7th of Edward VI., since which time the borough has returned two members to parliament: the right of election is vested in the burgesses possessing freehold property within the borough, and residing in the parish, the present number of whom is twenty-five, who are chiefly in the interest of Lord Wharncliffe and Edward Rose Tunno, Esq. The townhall, a small building, is appropriated also to the use of a charity school, which is chiefly supported by the mayor and burgesses, who appoint the master, and allow him a salary of £20 per annum. There are some remains of Bang Arthur's castle, on the top of a stupendous rock, formerly part of. the main land, but now connected with it only by a narrow isthmus j the summit comprises an area of thirty acres of pasture, but the acclivities are so steep, that it is almost inaccessible to the sheep that graze on it.
