The Vfeather, as to its character of Clear, Variable, and 

 Cloudy Days is given in Table IV (2), for each month and 

 also the year. 



This Table is introduced that it may be seen which relation 

 the Clear and Cloudy Days bear to the whole number. The 

 Clear Days are 32 per cent; Variable, 46 per cent; and the 

 Cloudy, 22 per cent of the whole number. 



The relation of clear weather to the direction of the wind 

 for the seasons and the year, is given in Table IV. (2.) 



For the year, the mean number of clear days in twenty 

 years are distributed as follows: 



17.5 occurs where the wind is N. N. E. 

 22.9 occurs when the wind is E. S. E. 



32.3 occurs when the wind is S. S. W. and 



26.4 occurs when the wind is W. N.W. 



By comparing this table with that exhibiting the relation 

 of rainy days to the direction of the wind, we shall see that 

 the greatest number of rainy days occur when the wind is S. 

 S.W., while the clear days occur when it is W. N W.
