The Hanover observations embrace but nineteen months, be- 
ing all which are in my possession. In this register the column 
headed ‘cloudiness’ is sometimes entered ‘fog.’ In taking the 
average I have called such an entry 10, which probably is some- 
times too great. 'This is the reason why the cloudiness at sun- 
‘tise in the warm months appears so high. Such entries, how- 
ever, are not made for either of the other hours. The two sets 
of observations being made at different hours, are not very well 
suited for comparison. Those, however, at 14 and 3 P. M. may 
be regarded as made about simultaneously. The cloudiness then 
at Hudson is somewhat more than half greater than at Hanover. 
Nearly the same ratio exists throughout the-entire year, but is 
somewhat greater in winter; when it is nearly as two to one. 
This is a very striking result, and exhibitsan important. feature 
of this climate. The Lake country in this respect resembles the 
western coast of Europe, and probably for a like reason. 
The following table exhibits the average number of daya i 
each month in which the sky was perfectly clear at the hours 
named. When the clouds cover less than one twentieth of the 
we heavens, the cloudiness is called 0.
