Devonshire is in parts extremely fertile, especially towards the south, and it has been called (in common, it is true, with other counties) the Garden of England. Two very large and specially productive areas are the Vale of Exeter, and the South Hams,--the latter a name somewhat indefinitely applied to the district south of Dartmoor and occupying a large part of the region between the Teign and the Plym, with Kingsbridge as its chief centre. The great fertility of this famous district is due partly to the nature of the soil, partly to the mildness of the climate and the shelter afforded by the heights of Dartmoor, and partly to its nearness to the sea. [Illustration: On Lundy] A very remarkable and interesting feature of Devonshire is Lundy--an island three miles long by one mile broad, lying out in the Bristol Channel, opposite Barnstaple Bay, and twelve miles north-north-west of Hartland Point. Its name, it is believed, is derived from two Norse words meaning Puffin Isle. Composed entirely of granite, except for its southern extremity, which is millstone grit, its lofty cliffs are very wild and rugged and picturesque, and for two miles along its eastern side there is a remarkable series of chasms, from three to twenty feet wide and some of them of great depth, known to the islanders as the Earthquakes. The shingle beach at the south-eastern corner, in the shelter of Rat Island, is the only landing-place, but many vessels find good anchorage on the eastern side, well protected from westerly winds. Many ships, however, have been wrecked among the terrible rocks round its base, including the battleship _Montagu_, lost in 1906, and, according to tradition, one of the galleons of the Spanish Armada. There is a lighthouse at each end of the island, and the southern one is the most powerful in Devonshire. Perhaps the greatest charm of Lundy lies, as will be shown in some detail in a later chapter, in its natural history, especially in the vast numbers of birds which visit it in the breeding season. Among very rare stragglers that have been shot here is the Iceland falcon, a species of which very few examples have been recorded for this country. A few plants and insects are peculiar to the spot. There are now few trees, except those planted not long ago near the owner's house in a cleft at the south-eastern end, but some shrubs, such as fuchsias, hydrangeas, and rhododendrons grow to a great size, and the mesembryanthemums are particularly vigorous and beautiful. Granite for the Thames Embankment was obtained here, but the quarries have long been closed, and farming is the chief industry of the few inhabitants.
