302 THE RAINFALL OF CORNWALL. 



rise to considerable elevations. The twin hills of Eoughter and 

 Brown Willy, the former 1296 the latter 1368 feet high lie on 

 the north western boundary near Camelford, whilst the eastern 

 edge rising boldly from the surrounding Lowlands, is crowned 

 by Trewortha Tor (1050 feet), Sharp Point Tor (1200 feet), and 

 Caradon Hill (1208 feet); and on the south and west the hills 

 bounding the district vary from 700 to 1100 feet in height, being 

 generally at about the same elevation. Between the Camel and 

 the Sea the land in places attains a height of from 300 to 600 

 feet, and on the north the descent is more gradual, the high land 

 approaching closely to the sea coast at Tintagel and Boscastle, 

 the great bulk of this Moorland district consisting of an elevated 

 boss of granite. 



A considerable number of stations are grouped around these 

 moors, Bodmin, Pencarrow, Lanteglos, and Camelford, on the 

 west, Grt. Eoughter Consols on the north, Alternun and St.- Cleer 

 to the east, and Liskeard and Warleggan on the south east border. 

 No station exists in the centre, but the rainfall at Great Eough- 

 ter Consols, 65-66 Ins., may be taken as indicating the Mean 

 Annual Fall. The rainfall varies at the western stations from 

 48 to 50 Ins. but a larger fall is shewn by these stations of 

 Liskeard, St. Cleer, and Alternun. At the former the fall at an 

 elevation of 620 feet, is 50-41 Ins., at St. Cleer, more nearly 

 approaching to the south east of the hill district ; although the 

 height above sea level is diminished to 375 feet, the rainfall 

 ris'es to 52-67 Ins. ; whilst at Altarnun, 50 feet lower, the rain 

 registered 62-12 Ins. per annum. 



The district lying in the east of Cornwall is undulating, but 

 the hiUs generally attain no great elevation, with the exception 

 of Kit Hill on Hingeston Downs, which is 1067 feet above the 

 sea ; here the fall is 63-06 Ins., but the ordinary amount varies 

 from about 40 to 52 Ins. at the various stations ; with the excep- 

 tion of Saltash, which has, according to the observations, the small 

 fall of 34-28 Ins. I am inclined, however, to think that some 

 exceptional cause must have been at work to give this result. 



The belt of land fringing the North Coast has the smallest 



rainfall in the county. At the Land's End 34-13 Ins. The 



station at St. Agnes is high, and on ground to the east of the 



■ Beacon (621 feet), which accounts for the relatively large amount
