We perceive that the cloudiness of Hudson is much greater 
than that of Hanover or Cambridge, at every season of the year. 
It is greater than that of Greenwich in winter, and is but slightly 
inferior for the remainder of the year. 
From Dec. 14, 1839, to Jan. 15, 1840, a period of 33 days, 
the sky was not free from clouds in a single instance at a regular 
hour of observation. From Aug. 10, 1844, to Sept. 14, a period 
of 36 days, the same was true; and from July 27 to Sept. 14, a 
period of 50 days, the sky was cloudless but once at a regular 
hour of observation. From Nov. 23, 1841, to Dec. 31, a period of 
39 days, the sky was never cloudless ; and from Oct. 29 to Dec. 
31,a period of 64 days, the sky was cloudless but once ata 
regular hour of observation, and during this period, the obscura- 
tion was generally total. It will be remembered that the sky 
is called cloudless, when the clouds cover less than one tenth 
of the visible heavens. Of all the places with which I am ac- 
quainted, Hudson is during the winter months the most cloudy. 
RAIN.
