 about 6 feet from the ground, upon the north side of a house^ 

 and protected from the direct rays of the sun. Hours of obser- 

 vation 7 A. M, and 3 and 9 P. M. The above abstract con-

from the three observations 



the mean of each month ; the high- 



est and lowest temperature of each month ; the greatest daily 

 range of each month^ and the day on which it happened ; and 

 the quantity of rain and snow in each month. 



Mean temperature for the year 44 JJ5,

Quantity of water 25.98 inches. 



Winds :Nr. W. 279 times ; S. 95 ; S. E. 74 j and S. W. 71 ;
