J. HOPKINSON—THE RAINFALL IN 1900 . 
unusually large. The only considerable fall of rain was on the 1st 
at one station (Bone Hill, St. Albans). The 1st was the wettest 
day at 4 stations, the 6th at 8, the 15th at one station, the 16th 
at 4 stations, the 24th at 18, the 28th at 5, the 1st and 24th were 
the wettest at two, and the 24th and 28th at two. 
December.— Yery wet, with rain on a large number of days. 
On the 5th the fall was considerable at 5 stations, on the 8th it was 
very considerable at one station (Apsley Mills), and on the 30th it 
was considerable at 2 stations, very considerable at 28, and great at 
Moor Park (1*00 in.) and Pendley Manor (1*01 in.). The 30th was 
the wettest day at all stations. 
Comparison with the Rainfall of the Adjoining Counties. —If the 
rainfall of Hertfordshire in 1900 be compared with that of the 
adjoining counties the result for the year will be found to be very 
similar to that for the previous year, our county having an excess 
last year of 14T percent, and in 1899 of 11 -2 per cent. Por the 
months the average at 20 stations in the adjoining counties shows 
a fall of rain about equal to that of Herts in March, May, July, 
and September (alternate months), but considerably less than that 
of Herts in all the other months of the year. The stations from 
which this result is deduced are—for Cambridgeshire, Wisbech, 
Thorney (Wryde), Ely, Cambridge (Trinity College), and Carlton 
Hall near Linton; for Bedfordshire, Aspley Guise; for Buckingham¬ 
shire, Buckingham (Adstock), Winslow, and Slough (Upton); for 
Middlesex, Harefield, and in London, Regent’s Park, Camden 
Square, and Old Street; and for Essex, Newport, Halstead, 
Braintree, and Chelmsford (Spergula and High Street). The 
mean monthly rainfall at these stations was—Jan., 2*94 ins. ; 
Eeb., 3*69 ins. ; March, 0*75in. ; April, 0*80 in. ; May, L16in.; 
June, 2*39ins.; July, L29in.; August, 2-80ins.; Sept., 0-61 in.; 
Oct., 1-85 in.; Nov., 1*90 in. ; Dec., 2-55 ins. ; and for the year, 
22*73 inches. 
In order to check this result so far as concerns the rainfall in 
the year, the mean fall at a much larger number of stations (one 
to every 40 square miles in each county) has been computed, 
representative stations as widely distributed as possible being 
selected. The result is as follows :—Cambridgeshire (21 stations), 
22*04 ins.; Bedfordshire (12 stations), 24*13 ins.; Buckinghamshire 
(18 stations), 25*02 ins. ; Middlesex (7 stations), 22 87 ins. ; and 
Essex (33 stations), 20*94 ins.; the mean for the whole of the 
91 stations being 22*60 ins. This value is very near to that given 
for the 20 stations for which the mean monthly fall of rain has 
been computed, and gives an excess for Hertfordshire of about 
31 inches. This is chiefly owing to the small rainfall in the large 
area occupied by the counties of Cambridge and Essex.
