RAINFALL IN HEETFOIID SHIRE IN 1880. 



225 



Bisfrihufion of liainfall ihroHghout the Conntij. — Tabic III. gives 

 the menu monthly ami annual fall iu each of tho.se four main river- 

 basius in which we have observers, showing the relation these 

 vahies boar to the moan of 1870-79. Iti each of these main districts 

 the fall was ahove the mean, the difference being greatest iu the 

 Colne district, and least in the Lea district. AVe may perhaps, iu 

 a great measure, attribute this relative difference to the large 

 amount of rain gauged at Moor Park on the one hand, and the 

 comparatively small amount gauged at Datchworth on the other ; 

 this latter being the only instance in which the fall was below the 

 mean of its district for the year. 



The four main river-districts being divided into eleven minor 

 districts, I here give the mean fall in each of these districts. 



We thus as usual can trace the greatest fall to the S.W. borders of 

 the county and the smallest fall to the I^.E. borders. 



We have next to consider the greatest falls of rain in 24 hours. 

 And first of all we may take the absolute maximum fall in each 



month wdth the station recording it.
