RAIN. 



With the change of temperature, I am of the opinion that less 

 rain falls, and that there are greater extremes of wet and drought, 

 than when the country was first settled, although the observations do 

 not extend over a period sufficiently long to determine the fact. The 

 following table will show the quantity of rain that fell at the several 

 points for three consecutive years :

It will be observed that the greatest extremes occurred at Chicago. 

 The mean rain-fall at Milwaukee for 25 years is 30.20 inches ; at 

 Toledo, for six years, is 38.94 ; at Lansing, for four years, 30.56 ; and 

 at Chicago, for the last three years, is 31.94 inches. The following 

 table will show the quantity of rain that fell, when the winds pre- 

 vailed from the different directions :
