1915.] 



RAINFALL OF GUERNSEY.

a period. These six years give a mean of 42 inches, or an 

 excess of 5*2 inches over the average. The wet years pro- 

 ducing this result are 1910 = 46*2 in., 1911 = 371 in., 1912 

 = 46-5 in., 1914 = 42*7 in., and 1915 = 43'4 in. 



Table II. — The distribution of the rainfall over the 

 island shows that the difference between the East and the 

 West coasts of the island has been greater than the average 

 by 2 inches, the West coast being only 85°/ of the rainfall of 

 St. Martin's Road. The falling off of rainfall from the Town 

 to the West, South-west, South and North is fully sustained 

 by the work of the year. Mr. Rowswell's station at Les 

 Blanches, although less than a mile distant from the St. 

 Martin's Road Station, has collected only 96°/ Q of St. Martin's 

 Road fall. It is also interesting to note the falling off on the 

 road to the West coast through the Grange and the Rohais. 

 Dr. Carey's station in the Grange collected practically 43 

 inches, while Mr. Guilbert's station in the Rohais collected 

 42 inches. The Rev. Stevens Guille collected just under 39 

 inches, while Mr. H. Jones at Cobo is credited with 37 inches, 

 and Mont Saint 35 inches.
