On examining table B, which consists of 44 stations from 
amongst the 48 whose averages were given for the 10 years 
1891-1900 in the Report for 1900, and comparing these aver- 
ages with the rainfall of 1902, we shall at once be struck with 
the fact, in looking at the year’s column, that the rainfall 
has been deficient, for out of all these stations only one shows 
an excess—viz. Hsher—and this excess, anyone can see, has 
arisen from the great thunderstorm on September 10th. If now 
we take the several months we shall at once see the cause of the 
numerous complaints which have been made as to the want of 
water. The months of January, February, April, July, October, 
November, and December were all very dry. March we might 
call an average month, the small deficit in some places being 
balanced by the small excess in other places. September also 
was a dry month in the places which were not affected by the 
thunderstorm on the 10th. This leaves only the three months of 
May, June, and August as the months of an excess of rain, and 
these are the months when most persons take their holidays. It 
will be noticed how wet these months were, and I may remark that, 
though July appears dry, yet the last half of that month was wet 
with a large number of rainy days. If we now look at table C, 
we at once notice that May, June, August, and October had a 
considerable number of rainy days in excess of the average. 
These facts will at once account for the impression that the 
year was a wet one. It is, again, a curious fact that the driest 
place in the district appears to be Sevenoaks, which is closely 
followed by Abinger Hall. 
Through the courtesy of a member of the Society, Mr. Baldwin 
Latham, who has a self-recording rain gauge, I have been fur- 
nished with the following figures for 1902. The actual number 
of hours during which rain fell during the year was 529°35, 
which gave a rate of fall of 0°39 in. per hour, and the actual 
number of days of twenty-four hours each as 22°056. 
The Committee would like to point out that the number of 
days on which the fall of rain was one inch and above was not 
large, being only five, and that the amounts, with the exception 
of the fall on September 10th, which has already been dealt 
a
