RHIW, a parish, in the union of PWLLHELI, hundred of CommiTmAEN, Lleyn division of the county of CARNARVON, NORTH WALES, 11 miles (W. a. W.) from Pwllheli; containing 371 inhabitants. This place derives its name, signifying the ascent of a hill, from its situation on the acclivity of Mynydd Rhiw, a lofty eminence that rises above the village to an elevation of one thousand and thirteen feet above the level of the sea. The parish, which extends across the isthmus of Lleyn, is situated on the western shore of the bay called Porthnigel, in the great bay of Cardigan, and comprises about 900 acres of arable and pasture land, whereof about two-thirds are ancient inclosure, and the remainder, which is mountainous, was inclosed by an act for that purpose, in the year 1811. The soil, in the lower grounds, is a stiff clay, and in the higher lands gravelly, producing tolerable crops of barley and oats, and excellent grass; and the inclosed commons afford good pasturage for sheep and young cattle. The surrounding scenery is pleasingly diversified, and is somewhat enlivened by several small rivulets which run through the parish. From the summit of Mynydd Rhiw. the prospect is strikingly beautiful, embracing the whole range of the mountains of Snowdon, and extending over Cardigan bay, St. George's Channel, and a great part of South Wales. Phis Rhiw, for many generations the seat of the family of Lewis, and now the property and residence of Lewis Moor Bennet, Esq., is an ancient and handsome mansion, comprehending within the grounds some picturesque scenery. Manganese, of very superior quality, abounds in the parish: the vein in which it lies, first discovered in 1827, has been worked since that time with very great success, and about fifty persons are now employed in procuring it, the produce being principally sent to the Liverpool market. The rateable annual value of the parish has been returned at £646. The living is a rectory, with the perpetual curacy of Llandudwen annexed, rated in the king's books at £6. 14. 91., and endowed with £200 royal bounty; present net income £97; patron, Bishop of Bangor: there is a glebe-house, with six acres of land, besides eleven acres purchased with the Bounty money. The church, dedicated to St. Aelrhiw, is an ancient and spacious cruciform structure, in the early style of English architecture, and is in good repair; i the length of the body Of the edifice is 63 feet, the breadth 21 feet, and the .transept measures 22 by 18. There is a place of worship for Independents, with a burial-ground attached. A school for the instruction of poor children was formerly held every fourth year in this parish, in rotation with that of BrS7ncroes (in which the tenement is situated that forms the endowment), and those of Aberdaron and Llanvaelrh,s; but it is now made permanent, and converted into a National school at 1311-ncroes, containing about 30 children, and supported partly by the endowment and partly by payments from the parents. There are also three Sunday schools, gratuitously conducted: one consists of about 30 males and females, who attend the Established Church; and in the other two, which appertain to dissenters, are about 60. Some land in the parish, now producing £4 per annum, was bequeathed for keeping i the church in repair.
