THE KAINFALL OF GUEENSEY FOE THE 

 YEAE 1915. 



BY MR. A. COLLENETTE, F.C.S. 



The year just finished has been a wet one, having exceeded 

 the average by seven inches nearly. 



The following months were wet : January, February, 

 July and December. December doubled its average total, 

 the three other months showing large excesses. 



The months March, April, May and June together 

 formed a dry group, which was 3 inches in deficit. 



Owing to the excesses of January and February there 

 was an excess from the very first of the year. At first the 

 excess averaged about 2 inches, but December rainfall raised 

 it to 6'6 inches. 



At the end of February the excess was 3^ inches, but 

 March reduced that to 2 inches, and by the end of June the 

 excess was reduced to half-an-inch. July then raised the 

 excess to 3 inches, finally December doubled that figure. 



December contributed one-fifth of the year's total, and 

 only five days were without rain. 



On six days the rainfall reached or exceeded 1 inch some- 

 where in the island, but no single station had more than five 

 days. The heaviest of these falls occurred on the 22nd July, 

 when St. Martin's Eoad measured 1*58 in. 



As regards the distribution of rainfall over the island, 

 St. Martin's Eoad has collected the largest total, 43*4 in., the 

 Grange was next with 42"9 in., the Forest third with 42*5 in., 

 the Eohais had 42 in., Les Blanches 41*8 in. The West 

 Stations were St. George, 38*8., Mont Saint, 35'7, and Cobo, 

 proportionately completed, 37*3 inches. There is thus a differ- 

 ence of more than 6^ inches between the wettest East Station 

 and the driest West Station. 



It is not necessary to lengthen this paper in discussing 

 details, as the tables will supply much on which to comment 

 on the abnormalities of the year. 



One point, however, I wish to point out not without 

 interest is the excessive rainfall of the last six years taken as
