RAINFALL IN HERTFORDSHIRE IN 1890 . 
185 
January,— Rather wet, but on no day was there a considerable 
fall of rain at any station. There were only two or three days 
together without rain except at a very few stations, and at most 
stations rain fell every day for the last 11 days. No snow is recorded 
to have fallen. 
February.' —Yery dry: at most stations there were two or three 
periods of about a week without rain. On 14th the fall was con¬ 
siderable at four stations, and on 15th at one. A little snow fell in 
the middle and near the end of the month. 
March.— Rather wet, but with several intervals of a few days 
without rain. On 19th the fall was great at Welwyn (1*05 in.), 
very considerable at sixteen stations, and considerable at seven. This 
was chiefly due to snow, small amounts of which also fell during 
the first few days, and a little on the 20th, the last fall of the 
winter. 
April.— Rather dry, with no considerable fall of rain on any day. 
Periods with rain for several days in succession alternated with 
similar periods without rain; thus at six stations there were three 
such wet periods and four dry ones, of nearly equal length. 
May. —Rather dry, and very similar in character to April as to 
periods of rainfall. On 9th the fall was considerable at ten stations, 
and on 10th at three. Scarcely any rain fell after 19th, the aver¬ 
age for the last 12 days being only 0 106 in., or at the rate of 
0*009 in. per day, being about one-seventh the mean daily fall for 
the year. 
June. —Rather wet; with very few days in succession without 
rain. On 4th the fall was very considerable at one station ; on 10th 
considerable at one; on 12th very considerable at one and considerable 
at five; on 18th considerable at one, and on 20th at one ; and on 
30th very considerable at two and considerable at six. 
July.— Excessively wet, as in the preceding year, and as then 
the excess was entirely due to a fall caused by a thunderstorm 
about the middle of the month, the rain in each case falling in two 
successive days, and being much the heaviest in the first of the two. 
On 4th the fall was very considerable at two stations and consider¬ 
able at six. On 17th, the day of the thunderstorm, the fall was (at 
least) great at all stations. For this day I give all the records I 
have obtained, i.e. including a few at stations for which I have not 
received returns of the rainfall during the year. The fall was 
excessive at Moor Park (4*19 ins,), "Welwyn Rectory (2-70 ins.), 
Danesbury, Welwyn (2*64 ins.), Brocket Hall (2*55 ins.), Rotham- 
sted (5 inch gauge 2*52 ins., 8 inch gauge 2*50 ins.), Therfield 
(2-48 ins.), Hailey bury, Hertford (2*48 ins.), Bushey Heath (2*15 
ins.), New Barnet (2*10 ins.), Gorhambury, St. Albans (2*08 ins. 
+ ?, gauge overflowed), Bancroft, Hitchin (2*02 ins.), High Down, 
Hitchin (2*00 ins.), and The Grange, St. Albans (2*00 ins.) ; very 
heavy at Royston (1*99 in.), Datchworth (1*91 in.), The Firs, 
Hitchin (1*88 in.), The Maples, Hitchin (1*87), Watford House 
(1*83 in.), Southgate (1*82 in.), Oaklands, Watford (1*81 in.), and 
Weston Manor, Stevenage (1*75 in.); heavy at Great Gaddesden
