Note 162c — Chapter V · OF THE TWO MOUNTAINS FROM WHICH THE NOBLE RIVERS WHICH DIVIDE WALES SPRING

Our author is again incorrect in stating that the river Maw forms, by its course, the two tracts of sands called Traeth Mawr and Traeth Bychan. This river, from which Barmouth derives the name of Abermaw, and to which Giraldus, in the fifth chapter of the second book of his Itinerary, has given the epithet of bifurcus, runs far to the southward of either of the Traeths. The Traeth Mawr, or large sands, are formed by the impetuous torrents which descend from Snowdon by Beddgelert, and pass under the Devil’s Bridge at Pont Aberglasllyn, so called from the river Glasllyn; and the Traeth Bychan, or little sands, are formed by numerous streams which unite themselves in the vale of Festiniog, and become an æstuary near the village of Maentwrog.
