Rain fell on 22 days, to the total depth of 4-36 in. (equivalent to about 20^

27th. 
The prevailing winds were south-westerly. 
The average velocity of the wind was 7 miles an hour. 
There were 98 hours of bright sunshine, equal to 30 per cent, of the greatest

November. — This was an extremely wet and stormy month, there 
being an almost constant succession of gales, some of them of great 
violence, which kept the weather in a very unsettled state. The 
dominant winds were south-westerly, and they brought with them not 
only a heavy rainfall, but also a temperature generally in excess of the 
average, and at times some really warm days. Night-frosts, too, were 
fewer than is usual at this season, and as a result the leaves remained 
in quite a remarkable manner on all deciduous trees till the end of the 
month. In nearly every part of the kingdom the rainfall exceeded 
the normal for the month, but in some districts the excess was large ; 
at the Wisley Gardens it was more than double the average, and the 
excessive wetness greatly hindered all outdoor operations ; indeed, in 
nearly all parts of the country work on the land was greatly retarded, 
and in the Thames valley, where there were heavy floods following 
upon the downpours of the first week of the month, it was to a great 
extent stopped altogether.

December. — At Wisley, and over the whole of the south-eastern 
portion of England, the weather of this month was in one respect very 
exceptional, inasmuch as there was an entire absence of rough weather, 
although December is as a rule the stormiest month of the year. In
