W.) from Llauvair; containing 517 bibs" bitants. This parish, which is situated nearly in the centre of the county, comprises about five thousand acres of arable and pasture land, for the most part in a good state of cultivation; the rateable annual value being returned at £2042. The surface is boldly undulated, and the soil is various; peat, which forms the principal fuel, is procured in abundance. The manufacture of flannel is carried on to a small extent, affording employment to a portion of the inhabitants. The living is a discharged rectory, rated in the king's books at fa 8. 4.; present net income, £176, with a glebe-house; patron, Bishop of St. Asaph. The churib, dedicated to St. Gwyddelan, is an ancient edifice, appropriately fitted up for the performance of divine service. There is a place of worship for Calvinistic Methodists; and one of Mrs. Bevan's circulating charity schools, attended by about 60 children, is held in the church. Rowland Evans bequeathed £15, the interest to be appropriated to the teaching of children; and Richard Pryce left £12, and the Rev. Mr. Jones £15, for the support of a charity school, the whole of which, amounting to £42, was lent to a person who failed; but the parish continues the payment of the interest to a master, fbr which four children are instructed. There are also two Sunday schools, conducted gratuitously, in one of which are 55 males and females, who attend the Established Church; the other, consisting of 260, appertains to Calvinistic Methodists. Various small charitable donations have been made for the benefit of the poor, producing altogether £1 per annum, which is distributed on Easter Monday. The Roman road from Caer-Sws to Chester is sup. posed to have passed through the western part of the parish, entering through the pass of Bwlch Cae Haidd, and proceeding to the Vale of Mochnant, where Sir R. Colt Hoare has placed the Mediolanwm ' of Richard's Itinerary. There are also some remains of ancient British fortifications, one called Pen-yGeer, surrounded with an intrenchment, and another on the other side of the Roman road, designated Lluest Cerig, or Carneddau; they appear to have been chosen as commanding the passes of Bwlch Haidd and Cevn C6ch, both of which are within view.
