2 COUNTY RAINFALL. 
The fluctuations of rainfall in Derbyshire from year to year 
may be seen from Table I., which shews the figures for ten con- 
secutive years at several stations, representing the various degrees 
of raininess in the County.

The average of successive periods of ten years is subject to 
much smaller variations than the rainfall of individual years, 
aud the average for any thirty consecutive years is very nearly 
constant, and may be looked on as a true average for most 
purposes. Table II. gives a comparison of ten year and thirty 
year averages for three representative stations.

From a consideration of all the available figures for long- 
period averages, we are able to arrive at the general distribution 
of rainfall. It must be remembered, however, that figures are 
not available for considerable areas in the north of the county, 
and consequently we cannot say with certainty where the wettest 
point is situated, although we have no doubt that it is not very 
far from the highest ground. We can, however, say definitely 
that the southern and eastern extremities of the county (south of
