RAINFALL OF GUERNSEY. 



Counting the three wettest stations, viz. : St. Martin's- 

 road, The Grange and Rohais, as 100, then the south of the 

 island had a rainfall of 97% ; the west, 86% ; the north, 79% ; 

 the south-west from 86% to 90%. L'Ancresse had 198 wet 

 days only ; Mont Saint still fewer with 194, but all the other 

 stations were in excess of 200 and the average of all stations 

 was 220. 



As was to be expected the droughts are but two in 

 number instead of, as last year, four. 



The partial droughts are also two, last year yielding 

 three. Heavy falls have been numerous, the wettest stations 

 yielding seven falls of one inch and over, but L'Ancresse had 

 one fall only of over 1 inch. 



The island as a whole received 43" which is 10" more 

 than the established average. 



Mr. Catford has been taking the rainfall at the Platte 

 Fougere lighthouse and has obtained a total of 17 ,// 76 or 48% 

 of the fall at Fort Doyle. This also represented only 36% 

 of the fall at St. Martin's. It is thus shown that the rainfall 

 induced by the rise of the land is exhausted by the time the 

 rain bearing air reaches the N.E. point of land.
