RAINFALL IN HERTFORDSHIRE IN 1902 . 
235 
At Berkhamsted on the 6th Mr. Mawley recorded a fall of rain 
for six minutes at the rate of nearly two inches an hour. 
September. —Very dry, the rainfall being little more than half 
the average, and with a very small number of wet days, nearly 
all in the first half of the month. On the 10th the fall was 
considerable at 4 stations. On the 11th it was considerable at 
9 stations, very considerable at 2, great at Grilston Park (1*14 in.), 
very great at The Eirs, Hitchin (1*33 in.), and Hertford Sewage 
Works (1*48 in.), heavy at The Chilterns, Hitchin (1*73 in.), very 
heavy at The Maples, Hitchin (1*83 in.), and excessive at High 
Down, Hitchin (2*21 ins.). The 2nd was the wettest day at 
4 stations, the 10th at 7, the 11th at 35, the 16th at one station, 
and the 2nd and 11th were the wettest at one. 
October.— Another very dry month for the time of the year, 
the rainfall being again only a little more than half the average, 
but there was about the average number of wet days. The only 
considerable fall of rain was on the 17th, at 7 stations, all in the 
Colne district. The 9th was the wettest day at 5 stations, the 
17th at 41, the 9th and 17th were the wettest at one station, and 
the 28th and 29th at one. 
November. —A dry month, but with rain on nearly the average 
number of days. There was no considerable fall. The 6th was 
the wettest day at 3 stations, the 24th at 5, the 28th at 12, the 
29th at 24, the 30th at 3, and the 6th and 29th were the wettest 
days at one station. 
December. —Another dry month, again with rain on but little 
less than the average number of days, and with no considerable fall. 
The 1st was the wettest day at 8 stations, the 14th at 2, the 15th 
at one station, the 16th at 3 stations, the 17th at 27, the 28th 
at 3, the 1st and 15th were the wettest at one station, the 1st and 
17th at 2 stations, and the 1st, 17th, and 28th at one station, the 
only instance in the year of the heaviest fall of rain in a month 
being equal on three days. Snow fell on several days in the early 
part of the month, and again on the 30th, but only to a very 
small amount. 
Comparison with the Rainfall of the Adjoining Counties .—The 
result of a comparison with the rainfall of the adjoining counties 
again shows an excess for Hertfordshire. The mean rainfall in 
the year at the same stations, with one or two exceptions, as in the 
previous year (one to every 40 square miles in each county), was 
as follows :—Cambridgeshire (21 stations), 18*61 ins. ; Bedfordshire 
(12 stations), 18*47 ins.; Buckinghamshire (18 stations), 20*17 ins. ; 
Middlesex (7 stations), 21*39 ins.; and Essex (33 stations), 19*29ins.: 
the average for the whole of the 91 stations being 19*36 ins. This 
shows an excess for Hertfordshire of about three-quarters of an 
inch, or nearly 4 per cent., which is much less than it was in 
either of the three previous years.
