RAIXFALL IN HERTFORDSHIRE IN 1882. 253 



greatest deficiency. The full of April 25tli was no doubt in a 

 great measure the causo of April taking rank as the second wettest 

 month in the year. Tlic mean monthly fall for 1882 differed from 

 the mean monthly fall lor 1870-79 by the following amounts: — 



January — 1-21 l^Iny — -46 September — -30 



February — -21 Juue -|- -58 October -f3-32 



March — -22 July — -46 November -f '-^^ 



April 4-l'22 August — "84 December -j" '"^ 



Distribution of Rainfall throxujhout the Coxmty. — In both the main 

 river-basins into which the county is divided the mean fall was 

 above the mean of 1870-79. In the Thames basin it exceeded the 

 mean by 2'71 ins. ; in that of the Ouse by r68. In the four river- 

 districts into which these two main river-basins are again divided 

 the excess was most observable in the Colne district, where it was 

 4*64 ins. above the mean, and least so in the Cam district, where it 

 was only -84 above it. 



In the minor districts into which the above-mentioned four are 

 again sub-divided the mean fall was — 



Lower Lea 26-51 ( Lower Colne 34-10 



Lea. 



Upper Lea 27-94 Colne < Ver 34-53 



Mimram 29-04 ( Gade 34-10 



Beaue 30-70 



Eib 28-76 Ivel Hiz 29-11 



Ash 28-19 Cam Rhea 24-43 



Thus it will be seen the Yer shows this year the greatest mean 

 rainfall ; whilst as usual the Hhee shows the smallest. Generally 

 it is the Lower Colne which shows the greatest excess. 



The absolute maximum fall for each month and the station at 

 which it occurs is as follows : — 



Jan. 8th— Therfield -73 July 12th— Hitchiu -In 



Feb. 14th— Thertield* -69 August 14th— ditto -41
