There is a called Gwaredog, a little to the S.E. of the last mentioned bridge, which is celebrated (according to our Welsh Pedigrees) as the birth-place of the renowned Patrick, the Patron Saint of the Irish; has genealogy is thus given, in Bonedd y Saint, published in the Myvyrian Archaiology: Padric Sant ap Alfryd ap Gronwy ap Gwdion ap Dôn o Waredawg yn Arvon. Several other places contend for this honor, such as Abergwaun, or Fishguard, in Pembrokeshire; Ystrad Clwyd, (or Clyde’s Dale) in Scotland, and several places in Ireland. The river _Gorfai_ is the boundary between the two Commots of Uwch and Is-Gorvai, in the Hundred or Cantrev of Arvon. About half a mile beyond Pont Newydd, on the right, is Dinas Dinoethny, the residence of Captain Jones.—This appears to have been one of the principal Roman Encampments in this neighbourhood, and to have had several small out-posts connected with it, which was the case also with Dinas Dinlle, a remarkable _tumulus_, or eminence, on the sea-coast, about two miles further, as well as with Craig y Dinas, on the river Llyfni, and Dinorwig, in the parish of Llanddeiniolen, before mentioned; a list of which, together with the subordinate Posts, connected with them, we shall hereafter insert. About a quarter of a mile beyond Dinas Dinoethwy, on the right, is Llanwnda, a small Church, dedicated to _St. Gwyndaf_. The Rectorial Tithes are annexed to the Headship of Jesus College, Oxford, and the small Vicarage, which is discharged and consolidated with the Chapel of Llan Faglan, dedicated to St. Baglan, situated near Aber menai, is in the Patronage of the Bishop of Bangor. The population of Llanwnda, in 1801, was 826, and of Llan Faglan 102. Near a small bridge, (as before-mentioned) called Glann y Rhyd, the Tourist will follow the left hand road until he arrives within a mile of the village of Llanllyfni, when he will again turn on the left, near a smithy, and proceed towards the Slate Quarries; and he will soon perceive, when he enters this little vale, that the Scenery here, as well as in most parts of North Wales, unfolds its beauty gradually as the traveller advances, until at last it displays itself in all its grandeur and magnificence. This Defile is bounded on the South and East by mountains of considerable height and magnitude, which assume a variety of shapes and characters as we proceed. It was from this narrow vale, which is but little known to strangers, that Wilson took his celebrated view of Snowdon, which has been so much and so deservedly admired; the situation was probably near the Nantlle Lakes, where Edward I. in the summer of 1284, resided for some days; and from thence issued several of his Edicts, some dated July 17, and others the 20th, and one from Carnarvon, as late as the 22nd of October in the same year, which shews what attention he paid to the establishment of governments in his new Dominions. The place which he occupied here during that time, was
