The river was clear of ice on the 10th day of April, and closed on 

 the 9th of December, being the day on which the anchor ice referred 

 to was formed, the temperature changing at the same time from 

 thirty-three to thirty-two degrees. 



I have observed that in extreme cold weather, the vapor from the 

 falls has a very sensible effect upon the temperature of the atmos- 

 phere, the mercury commonly standing four or five degrees higher 

 within a few rods of the river, than it does at the distance of one 

 fourth of a mile. John M. Batchelder.
