RAINFALL OF GUERNSEY. 



In studying the second table and comparing last year's 

 results with those of 1 903 it must be noticed that the reference 

 numbers are changed. This has been rendered necessary by 

 plan adopted of, first, showing the stations in order of elevation, 

 and second, of grouping the stations in order of their position 

 in the island. It has been found that, as a rule, both elevation 

 and position are factors which have a large influence on the 

 rainfall, hence it is convenient to thus group the stations. 



To avoid unnecessary work in the compiling and printing 

 the tables the reference numbers and the grouping are used 

 instead of the names of the stations in all the tables. 



The fall for 1904 has exceeded the average by 1*10 inch. 

 This excess has been insufficient to alter the 62 years' average 

 which remains at 36*62 inches, as it was for the previous year. 



There have been differences in the month's totals, but 

 they are equally divided into six wet and six dry months. 

 The wet months were January, February, May, July, 

 October and December. The greatest departure from the 

 average was in February, that month being 2*33 inches in 

 excess of its average. October was, as usual, the wettest 

 month, having given a total of 5*94 inches. The next wettest 

 was January, with 5*19 inches. February follows with 4*97 

 inches, the remainder give no totals reaching 3 inches. The 

 driest month was April, with 1*35 inches, closely followed by 

 March and May.
