LLANVIHANGEL-YSCEIVIOG, or LLANVIHANGEL-PENTRE-BERW (LLANFIHANGEL-YSCEIFIOG), a parish, in the union of BANGOR-AND-BEAUMARIS, hundred of MENAI, county of ANGLESEY, NORTH WALES, 8 miles (W. by N.) from Bangor; containing 947 inhabitants. This parish, which is of considerable extent, has been progressively improving since the new line of road from Bangor to Holyhead was brought through it, which has also been productive of much benefit to the surrounding country: the soil is various in different parts of it, and in some places rather large portions of marshy land occur. The village is small, but has a post-office dependent on that of Bangor. Coal of a particular kind, called "mountain coal," of a very soft quality, exists in the parish, and as the stratum of it here found is the only one in the island, the procuring of it is of very great advantage, although the expense of working it is considerable, arising from the marshy nature of the land, and the quantity of water with which the mine is inundated: to overcome these obstacles, a steam engine of great power has been erected, and the colliery is conducted upon an extensive scale, affording employment to about 200 men; six shafts have been recently sunk, and very superior coal is now raised. A railroad was projected from Penrhyn-Mawr coal-works, in the parish, to Red Wharf, in Llanbedr-G5ch, a distance of seven miles, under the provisions of an act of parliament obtained 148 in 1812, by which the proprietors were incorporated under the name of the " Anglesey Railway Company;" but the work was never carried into effect, as the supply of coal then raised was insufficient to make any return for the money to be expended. The living is a perpetual curacy, with that of Llanfinnan annexed, endowed with £10 per annum private benefaction, £800 royal bounty, and £400 parliamentary grant; net income, £97; patron, the Dean of Bangor, to whom the great tithes of the parish are appropriated, as forming part of the endowment of the deanery. The church, dedicated to St. Michael, is a spacious and ancient structure, consisting of a nave, south aisle, and chancel, and having on the north side a small building called Capel Berw, communicating with the church, and evidently of more recent date than the rest of the edifice. At Gaerwen, in the parish, is a large place of worship for Calvinistic Methodists, capable of holding 800 persons, and which, being situated upon elevated ground, forms a conspicuous object to a considerable distance. The Rev. Dr. John Jones, Dean of Bangor, in 1719, bequeathed £100, in trust, to be appropriated to the payment of a master to teach twelve poor children of this parish and that of Llanfinnan to read. A National school was built in 1828, by subscription, and is supported by the interest of the above £100, with a house and garden, granted in perpetuity by Holland Griffith, Esq., and by subscription amounting to £20 per annum; the total number of children is about 80. The Methodists, also, support three Sunday schools, in which are 215 males and 185 females. There are some small charitable donations, the interest arising from which is annually distributed among the poor during the winter: the principal of these are a grant of 24 yards of cloth and 24s. in money to be divided among six of the poorest old men, charged on certain lands in the parish of Llangafo, by — Williams, of Bug-den, more than a century since; a bequest of a rent-charge of6s., by Mrs. Holland, to be given in bread to the poor; and another of £5 by Thomas Williams, with which latter sum and other funds of the parish four small cottages were built, three of which are occupied by widows rent-free, and the other by a family. Two poor men of the parish, also, are entitled to a room, with an annuity of £6 each, in the endowed almshouse at Penmynnedd; and alternately with Llanfinnan, a third poor man participates.
