Be turns of Kainfall in

By R. STEVENSON HENSHAW, C.E. 



17 ROM the 70 returns which have been received 

 this year I have selected 24 for the purpose 



of the averages and calculations contained in 

 Tables 3 and 5, as against 20 such returns last 

 year. The stations from which these returns 

 have been sent are spread fairly equally over 

 the whole county. 

 The average rainfall calculated from these 24 stations is 

 44' 624 inches, with an average number of wet days of 199' 7, 

 whilst the average rainfall calculated from all the 70 stations 

 is, I find, 44-418 inches. 



1912, therefore, as far as Dorset is concerned, was wetter 

 than any year since 1872, the ratio, as will be seen from 

 Table 5, to the 57 years' average, 1856 to 1912, being 132, 

 against 126' 5 for 1903, the next wettest year. 



However, taking England and Wales, or the British Isles 

 as a whole, Dr. Hugh R. Mill has kindly informed me that 

 1903 was wetter than 1912 as 128 is to 121 for the former, 

 and 128 to 115 for the latter, the relative values being 

 expressed as a percentage of the average general rainfall. 



It will also be seen from Table 5 that three years out of the 

 last four have been considerably wetter than the average, 

 and consequently, therefore, the average for the county has 

 been raised.
