NANTLLE, a village in Carnarvonshire; on a lake and a railway of its own name, at the head of the river Llyfni, in a romantic and magnificent glen, under thewestern offshoots of Snowdon, 9 miles S S W of Carnarvon. It is the centre of a great quarrying and miningregion; and it has a station on the railway, and a post-office under Carnarvon. The scenery around it is considerablydefaced by heaps of rubbish, and by smoke from slateworks, and from workmen's cottages; yet is always imposing, and, at the gathering of a storm, is profoundly impressive. The railway station used to serve for a greatextent of country to the S; but has been mainly superseded by the new lines from Carnarvon to Portmadoc, and from Portmadoc to Dinas and to Pwllheli.
