 CLIMATE 65 harvest is of different fibre morally and physically from the inhabitant of northern climes who wins a scanty subsistence from the land at the expense of unremitting toil. These are extremes ; but even within the limits of a county, perhaps, similar if smaller differences may be noted, and the man of the plain or the valley is often distinct in type from his fellow of the hills. Very minute records of the climate of our island are kept at numerous stations throughout the country, relating to the temperature, rainfall, force and direction of the wind, hours of sunshine, cloud conditions, and so forth, and are duly collected, tabulated, and averaged by the Meteorological Society. From these we are able to compare and contrast the climatic conditions in various parts. Cornwall, being so surrounded by the sea, and so peculiarly under the influence of the Gulf Stream, may be looked upon as possessing a local "insular" climate in a marked degree. The south-west wind almost invariably brings rain and warmth together, for the high cold granitic moorlands are naturally calculated to arrest these warm airs and chill them, causing thereby a downfall of the suspended water. But Cornwall does not enjoy the amount of sun heat to ripen fruit that is obtained on the east coast of England, and it is exposed to furious gales from the west. "The gale from the west," says Polwhele, "is here no gentle zephyr; instead of wafting perfume on its wings, it often brings devastation." On the north coast every tree that is exposed to it is dwarfed and bowed like a curling wave, and the foliage in spring is G. c. 5
