The usual route, and the one which we intended to pursue, laying by St. Asaph and Chester, we determined first to explore some of the beauties of the vale of Conway; and with this object in view, took the road leading to Llanwrst: it possesses the charming varieties of wood, water, and a richly cultivated country, backed by mountain scenery. We soon reached Caer Rhun, the site of the ancient Conovium of the Romans, where the tenth legion were stationed. The late Rev. Hugh Davies Griffith, vicar of the parish, and a gentleman well known for his antiquarian researches, traced out here the remains of a Roman pottery: many utensils of various sorts had previously been found, mostly imperfect, some well designed and very curious. Amongst other things found here, was a small brazen circular shield, of curious workmanship, embossed, a little more than a foot in diameter, and with a projecting pike of wrought iron, of about four inches and a half, placed in the centre; it had circles of brass studs, and appeared to have been lined with leather and stuffed with hair. Numerous Roman coins were likewise found, and near this is a hill, called Myndd Caer Leon, or the _Hill of the Legion_. Mr. Williams says, “This legion was denominated Antoniana Augusta. The XXth, stationed at Chester (Caer Lleon Gawr, or Caer Lleion ar Ddyfrdwy), was distinguished by the name of Vicessima Victrix: and the Second Legion, stationed at Caer Leon, in Monmouthshire, or Caer Lleon ar Wysc, was known by the title of Augusta Britannica. There was, no doubt, a Roman road from hence to Segontium, on the west, and to Varium or Bodvarri and Caerwys on the east, and another probably through Dolyddelen, to Sarn Helen and Tommen y Mur, in Merionethshire; Pen y street, Dolgelly, Castell y Beri, near Tal y Llynn, to Penal, near Machynlleth, where there was a Roman encampment, and where very considerable remains were discovered.” The next object worthy of attention is Rhaiadr Mawr, or the Great Waterfall, about seven miles from Conway; Mr. Bingley’s account of which is so correct and spirited, that I shall give it verbatim:—
