CLIMATE OF THE VALLEY OF THE MOHAWK. 
25 
winds from different points of compass on the temperature, I venture to transcribe the 
results of some observations made by myself at Ogdensburgh, in the year 1838. I consider 
that locality a pretty fair one for the experiment. 
In the following table, the second column shows the number of days, hours and minutes 
that the wind blew from each point of compass during the year ; and the third, the average 
rise or fall in the thermometer per hour during each wind, expressed in decimals of a 
degree. The sign + denotes a rise, and the sign — a fall.

Now if the effect of the different winds is the same in the valley of the Mohawk as at 
Ogdensburgh, and if we regard the west winds at Utica and Whitesboro as coming from 
the northwest, the following statement of the number of observations at which the winds 
blew from the several points of compass at each place for the past seventeen years, so far 
as reported, shows that they must reduce the temperature.
