THE KAINFALL OF GUEKNSEY FOR THE 

 YEAR 1907. 



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



The rainfall for tlie year 1907 at Brooklyn is 34*00 inches, 

 and as the average of the last 65 years is 36*50, there is a 

 deficit of 2*50 inches. Table I. will be found to give the 

 rainfall at " Brooklyn," St. Martin's Road, from which we find 

 that 1907 is the third year in succession in which the total has 

 fallen below the average. 1903 and '1904 were above the 

 average, but these were innnediately preceded b}^ two years of 

 low rainfall, thus during the last seven years, not to go further 

 back; there have been five dry and two wet years. The 

 average in 1902 was 36*52 ; this rose during the wet years to 

 36*62, but the last three years has again brought it down to 

 36-50. 



As regards the distribution of rain during the year, 

 April, May and October were wet and contributed together 

 14*57 inches out of the 34. April gave 9*3° ., of the year's fall 

 instead of 6*3°/^ its average contribution. May gave 10*3"^ 

 instead of 6*8°/^, and October gave 23*37o instead of 13*3°/^, 

 that is together just under 43°/^ instead of 26°^. One month 

 was very dry, March, which contributed 0*75in. or 2*2", ^ of the 

 year's fall instead of 6*7° q. September was l*66in. under its 

 average total, that is less than half. The other dry month 

 differing largely from its average was January with l*67in. 

 deficit. 



The wet days were also abnormal, for althongh the ([uan- 

 tity of rain in the year was less than the a\ erage, there Avere 

 twelve more wet days, resulting, no doubt, from the average 

 dady falls being lighter than usual. 



As regards the distribution of rainfall over the island, I 

 feel that we are gradually advancing to a certain knowledge, 

 and I bring before you a few facts gleaned from Table III. 

 First, there is a decided improvement in the distribution of 

 the gauges. Before this year the furthest gauge to the S.AV.
