RAINFALL OF GUERNSEY. 



315 



(an old station revived), and Mont Saint. No total can be 

 given for these three stations, but the (Table II.) gives the 

 monthly totals of completed months. 



I consider that the results obtained this year are, in the 

 main, consistent with those of former years, but there are 

 differences. As compared with last year the southerly and 

 westerly stations are nearer to the quantities collected in 

 town and those to the north have diminshed. This, of 

 course, is largely due to the direction of the prevailing winds. 

 The variation amounts to 9 inches and the range in wet days 

 is 38. 



The island, as a whole, has had a mean fall of 33^ inches, 

 and the fall at Hautnez fairly represents the mean of all the 

 stations. 



Mr. Rowswell has handed me in returns from Alderney 

 and Sark, as well as those taken with a gauge on the roof of 

 the Library. From these returns it will be seen that the 

 Guille-Alles roof has collected 35*55 inches, about 1^ inches 

 less than at St. Martin's Road. Sark has had 10 inches less 

 and Alderney 7 inches less. The detail of the months' totals 

 are consistent.
