It is in the royal "forests" of Exmoor and Dartmoor that nearly all the chief rivers of Devon take their rise. Of these moorland tracts, the one extending into the extreme north of the county from Somersetshire, the other forming, so to speak, its backbone, Dartmoor is considerably the larger; and in High Willhayse and in the better known Yes Tor, its highest points, it touches an altitude of just over 2,000 feet, overtopping Dunkery Beacon, the monarch of Exmoor, by some 370 feet. Between the two moors there is a general resemblance, less, however, of contour than of tone, for while Exmoor swells into great billowy tops, the Dartmoor plateau breaks up into rugged "tors"--crags of granite that have shaken off their scanty raiment and now rise bare and gaunt above the general level. Both, as many a huntsman knows to his cost, are beset with treacherous bogs, out of which trickle streams innumerable, some, like the Wear Water, the chief headstream of the East Lyn, soon to lose their identity, others to bear to the end of their course names which the English emigrant has delighted to reproduce in the distant lands that he has colonised. Not strange is it that with loneliness such as theirs, Exmoor and Dartmoor alike should be the haunt of the mischief-loving pixies, who carry off children and lead benighted wayfarers into quagmires; of the spectral wish-hounds, whose cry is fearsome as the wailing voice which John Ridd heard "at grey of night"; and of the rest of the uncanny brood who once had all the West Country for their domain. Exmoor, too, is almost the last sanctuary, south of the Tweed, of the wild red-deer; and hither in due season come true sportsmen from far and near to have their pulses stirred by such glorious runs as Kingsley has described.
