The Teign, another of the streams that rise in the Cranmere bog, is famous both for the beauty of the scenery along its winding shores and for the many prehistoric antiquities--stone circles and alignments, menhirs and tumuli--which stand near them. Its two main branches, the North and the South Teign, meet about a mile to the west of Chagford. To the east of that moorland village the river flows through beautifully wooded valleys, and is joined on its right bank, below Chudleigh, by another Dartmoor tributary, the Bovey, on which stand Bovey Tracy, famous for its beds of lignite and clay and for its potteries, and North Bovey, near which are the remains of the very remarkable Bronze Age village of Grimspound. Below Newton Abbot the Teign becomes a broad estuary, on or near whose shores are five of the townships that are named after the river, the most important of which is the little port and well-known watering-place of Teignmouth. The river mouth is almost blocked by a low promontory, which, although now built over, was once a mere sand-bank or dune, from which latter word, no doubt, it takes its name of the Den. [Illustration: The Axe at Axminster Bridge] Other south-coast rivers are the Axe--one of whose two main branches rises in Somerset and the other in Dorset--which gives its name to Axminster and Axmouth; the Otter, which rises in the Blackdown Hills, and flowing past Honiton, Ottery St Mary, and Otterton, reaches the sea at Budleigh Salterton; the Aune or Avon, especially famous for its salmon, the Erme, and the slopes Yealm, small but beautiful streams rising on the southern slopes of Dartmoor, widening into estuaries as they near the English Channel, and giving names to Aveton, Ermington, and Yealmpton, respectively. The Plym, after which are named Plympton, Plymouth, and Plymstock, is another Dartmoor river, flowing through some very beautiful country, especially in the neighbourhood of Bickleigh, and at length forming a broad and important estuary known first as the Laira, and lower down as the Catwater or Cattewater, which joins Plymouth Sound.
