results show the usual predominance of winds from south-west, particu- 
larly in the winter months. East winds are very infrequent, averaging 
only 2:5 percent. North and north-east winds show a marked maximum 
frequency in the spring and early summer.

The station at Belvoir Castle is not well exposed for observations of 
wind force. From observations of the highest wind each day at 
Lutterworth, Mr. Binns concludes that January is the windiest month and 
September the quietest. 
SUNSHINE. 
In Table VI the first column of figures shows the mean daily duration 
of daylight in each calendar month. The second column shows the 
mean daily duration of sunshine, adjusted to the standard period 1881— 
1915, as registered by the Campbell-Stokes sunshine recorder at Belvoir 
Castle. ‘The third column shows the mean recorded sunshine expressed 
as a percentage of the possible duration—that is to say, as a percentage of 
the value given in the first column. 
May is the sunniest month, with an average daily duration of 6-55 hours, 
42 per cent. of the possible amount, a value which compares favourably 
with the records at other inland stations. ‘The winter sunshine at Belvoir 
Castle is relatively abundant, being exceeded only at stations on the
