On Tuesday, the 4th inst. the members of the Brecon Cymreigyddon, together with several friends of the Society, assembled at the White Lion, to celebrate their fifth anniversary, and had the gratification of seeing the accomplishment of one object which had originated among themselves, and which had for some time occupied their attention, as their President, the Rev. Thomas PRICE, did, on that day, present to the Society a complete copy of the translation of the New Testament into the Breton language, which had just been printed in France under directions of the Bible Society. In the course of the evening the several prizes of the Society were adjudged - that for the best Welsh verses upon the Battle of Navarin, was awarded to GLANMEHASCYN, the veteran bard, who, from having been himself once engaged in similar scenes, was well calculated to describe the dreadful conflict. - The reward for the best Welsh speech, on the benefits which have accrued to Great Britain during the illustrious reign of the House of Brunswick, was given to Mr. David GEORGE. The meeting was addressed in the Ancient British by the Secretary, Mr. Thomas JONES, and several others, and during the evening Mr. JONES, the Society's Harper, together with one of his pupils, played several national airs upon the triple harp. The Agricultural Meeting for the three Commots, Carmarthenshire, was held on the 11th instant, at the town of Kidwelly. The ploughing match took place in a field, on the farm of Middlescomb, near that town. There were 26 ploughs produced. The first prize was awarded to John WILLIAMS, of Pistill, Llandeveylog; the second to John DAVIES, Gellygatrog, Llangendeirne; the third to David DAVIES, Middlescomb; the fourth to William FRANCIS, of Blaeurbydw, Llandeveylog; and fifth to J. JONES, of Coed, Llaudeveylog. The ploughing was excellent, and the exhibitions very good. About forty gentlemen sat down to a sumptuous dinner at the Pelican Inn, R.J. NEVILLE, Esq. in the chair.
