Mill: Twenty-nine Years’ Rainfall at Wetwang. 253 
Perhaps the most striking feature of this table is that 
September, the driest month, is sandwiched between the two 
wettest months of the year; the high value in August is 
probably due to the frequency of thunderstorms. 
In the main table, the amount of rain in those months 
during which 4°00 inches or more fell, is given in heavy type, 
and there were twenty-seven such months of heavy. rainfall 
during the twenty-nine years. Of this number, October claims 
ten, August coming next with four. During the whole period 
covered by the observations, no such record occurred in Feb- 
ruary, March or November, and only one each in January, 
April, May and September. The wettest month was October 
1885, when 6°75 inches was recorded. 
In eleven months the rainfall did not amount to ‘50 inch, 
there being three instances in June, two in February, and one 
each in March, May, August, September, October and December. 
The driest month in the record was June 1887, with only .o8 
of rain. 
The last two columns of the main table give the greatest 
daily falls in each year, with the date of occurrence. This 
shows that the rainfall exceeded 2.00 inches, on only two days 
in the whole twenty-nine years’ observations. The first 
instance was a fall of 2°10 inches on October 14th, 1892, and 
this single day’s record represented 7°3 per cent of that year’s 
total fall. This day was. one of exceptionally heavy rain 
throughout the whole of Yorkshire, and formed the subject 
of a special discussion in ‘ British Rainfall,’ 1892. The only 
heavier fall in the record was on August 3rd, 1900, when 3.19 
inches or 10°6 per cent. of the whole year’s fall was measured. 
Correspondingly heavy falls occurred in the east and north 
of England on that day, falls greater than any previously 
reported occurring at several stations in Yorkshire. Of the 
twenty-nine maximum daily falls, August, October and Novem- 
ber each claim five, June had four, May three, July and Sep- 
tember two each, February, March and December one each. 
The heaviest daily fall of the year never occurred in either 
January or April. 
The importance of securing the establishment of new records 
of rainfall in the East and North Ridings is very great. While 
the West Riding is better supplied with rainfall stations than 
most parts of England, the other divisions of Yorkshire are 
worse off in this respect than almost any other county. Ob- 
servations such as those carried out by the late Mr. Maule 
Cole are very simple, and of great value both to science and 
in practical matters. Full information as to instruments and 
free instructions can always be obtained from the British
