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 locahty a pretty fair one for tlie experiment. 



In the following- table, the second column shows the number of days, hours and minutes 

 that tlie wind blew from each point of compass during the year ; and the third, the average 

 rise or fall in tlie 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.
