Along the northern seaboard of Devon there runs a series of magnificent cliffs, in parts heavily wooded, whose dark walls, sloping steeply to the shore and with projecting bases suggestive of the ram of a battleship, are relieved at many points by deep, rocky clefts, known variously as combes or mouths; each with its stream, each green with ferns and oak-coppice and thickets of thorn and hazel, and each with its butterfly-haunted clumps of tall hemp-agrimony. [Illustration: The Castle Rock, Lynton] Down such a hollow, the deep and finely-wooded valley of Glenthorne, runs the border-line that divides Somerset from Devon. Rather more than three miles west of it there stands out into the Bristol Channel the dark mass of Countisbury Foreland, the most northerly point in the county, and one of the highest along its coast, 1100 feet above sea-level. Four miles beyond the Foreland, at the mouth of a deep and well-wooded valley, down which runs the beautiful trout-stream from which it takes its name, is Lynmouth, famous for its scenery, of which two striking features are the Watersmeet on the river, and the Valley of Rocks on the coast. A port and fishing-village up to the close of the eighteenth century, its small tidal harbour is visited now only by a few small coasting vessels. About four miles west of Lynmouth is Heddon's Mouth, a little bay at the foot of towering cliffs, with another trout-stream flowing down to the sea through one of the loveliest combes in North Devon. Five miles of cliff stretch from Heddon's Mouth to Combe Martin Bay, a little inlet lying in the shelter of two conspicuous heights, the Great Hangman and the Little Hangman--names associated with no tragic story, but derived, like many others round our coasts, from the Celtic _maen_, a stone--and with its village, once famous for its rich silver-mines, running a mile inland. Two miles of rock-bound and dangerous coast, swept, especially off Rillage Point, by a strong tide-race, extend from Combe Martin Bay to the ancient port of Ilfracombe, whose mild yet bracing climate and beautiful surroundings have made it the most popular seaside resort in North Devon. Its little land-locked harbour is almost surrounded by lofty hills and rugged cliffs, whose beauty is greatly heightened by the varied colouring of the rock and by the vivid green of the abundant vegetation.
