(in 1822) ; making a difference of almost 15 inches — the one 

 being a year of unusual wet — the other of distressing drought. 



The most rain which has fallen in one day, for the last 

 ten years, was 4 inches. 



The quantity of snow during the last five years, was as

The water which fell in the form of snow, is included in 

 the table of rain. The quantity of snow, for the last ten 

 years, was 194 inches, or about 16 feet — averaging nearly 

 20 inches a year. The deepest snow in that time, was 18 

 inches; which fell on the 7th January, 1821. The usual 

 depths have been from 2 to 4, or 5 inches. It is quite cer- 

 tain, I think, that the quantity of snow, in this region, is 

 much diminished within half a century — and, indeed, within 

 the last thirty years. The same remark may be made re- 

 specting its duration, after it has fallen ; both which circum- 

 stances are probably owing, in a great measure, to the clear- 

 ing of forests, and the extended cultivation of the country. 



The number of days of falling weather, (including rain 

 and snow,) is exhibited in the following table : —
