LLANVAIR-CLYDOGAU (LLAN-FAIRY-CLYWEDOGAU), a parish, in the union of LAMPETER, upper division of the hundred of MOYTHEN, county of CARDIGAN, SOUTH WALES, 4 miles (N. E. by E.) from Lampeter; containing 471 inhabitants. This parish is bounded on the south by Cellan and Lampeter, on the north-east by Llandewy-Brevi, and on the west by Llangyby; and is pleasantly situated in the upper part of the Vale of Teivy, that river flowing through the parish, and being here crossed by a bridge of two arches, opposite to the church; it is also intersected for three miles by the turnpike-road leading from Lampeter to Tregaron; and the parish contains two hamlets, one on each side of the Teivy. The surrounding scenery is characterised generally by those features which prevail in this part of the principality, and the views from the higher grounds embrace extensive prospects over a richly-diversified tract of country. The soil, though various, is in general 'fertile, particularly on the lower lands, and the substratum abounds with mineral wealth: oats and barley are the chief agricultural produce; and the prevailing kinds of timber are oak and ash. A valuable mine of lead-ore, containing a considerable proportion of silver, and in which also are found quartz, spar, and a small quantity of copper-ore, has been worked for the last thirty years with considerable success, though in dry seasons during that period the works have been frequently suspended from want of water sufficient to give motion to the machinery employed: the works are at present carried on at a depth of 120 two hundred and fifty feet below the surface, and offer sufficient encouragement for the continuance of the operations: the average produce of the mine, which is the property of Lord Carrington, the chief landed proprietor, is twenty-five tons of ore per annum, each ton of which contains upon an average from seventy-five to eighty ounces of pure silver. The living is a perpetual curacy, endowed with £800 royal bounty; net income, £65; alternate patrons, Lord Carrington and Captain George Laurence Vaughan, the impropriators; whose tithes have been commuted for a rent-charge of £180. The church, dedicated to St. Mary, is a small and very ancient structure, not possessing any architectural details of importance. There is a place of worship for Wesleyan Methodists; and there are three Sunday schools, two of which afford gratuitous instruction to 100 males and females, and in the third, which for a part of the year is also a day school, about 30 children are taught at the expense of their parents. Contiguous to the lead-mines was an ancient family mansion of the Lloyds, one of whom represented the county in parliament in the reign of Charles I., but vacated his seat upon the condemnation of the unfortunate Strafford: a contemporary historian describes Mr. Lloyd as a 64 gentleman and a scholar, noblyjust in his deportment, and naturally fit to manage the affairs of his country." This mansion latterly belonged to the family of Jobnes of Havod, and was the residence of the father of the late lord-lieutenant of the county till his marriage, after which time it was suffered to fall into a state of decay. It was a building of very great antiquity: the walls were in some parts five yards in thickness, and in several parts of the building there was the date 1080: it is now a ruin, having fallen down within the last few years. On the hills in some parts of the parish are the remains of ancient earthworks, but not of sufficient interest to require minute description.
