Meteorological Table^ ^c. — Remarks, 2S9 



REMARKS. 



Fj'om the foregoing table, it appears, that the mean tem- 

 perature of the last twelve months was 44.2, which was 

 about 1° colder than the twelve months preceding. The 

 temperature of the summer months was - - 67.8 



winter do. - - - 19.9 



Difference, - - - 47.9 



That August was 2° warmer than the other summer months, 

 and February about 2° colder than the other winter months. 

 That March was 3° colder than December, and June warm- 

 er than July. The highest temperature was 90°, and was 

 the same on the 27th day of June, and on the 26th day of 

 August. The lowest temperature was on the 1 Ith of Janu- 

 ary, and was 22° below zero. But it fell below zero eigh- 

 teen nights within the months of January and February. 

 We had lightning and thunder on forty five days ; Aurora 

 Borealis was seen on ten evenings only. 



The quantity of water which fell in rain, hail and snow, 

 was 73.3 inches, which is believed to be beyond a parallel 

 in the recollection of any man living. The whole quantity 

 of snow was 100 inches, which is only 3 inches more than 

 fell in the winter of 1826 — 7. 



On the 2d, 3d and 4th days of Sept, there fell 9.7 inches 

 of rain, which produced a most destructive freshet, through- 

 out Vermont and New Hampshire, the ravages of which will 

 probably be visible for half a century. 



For many years, since I have resided in Vermont, I have 

 been of opinion, that much more water falls annually in rain, 

 hail and snow, upon the Green Mountains, than in most oth- 

 er parts of the United States; and from three years' accu- 

 rate observation, I am confirmed in the belief. In the win- 

 ter months it is a common occurrence that there are storms 

 upon the mountains, when ten or fifteen inches of snow fall, 

 and at the same time, only a few miles distant, at the foot of 

 the mountains, on the west side, they have very little or no 

 storm of any kind. So in the summer, the clouds are often 

 seen to accumulate over the mountains, and there exhaust 

 themselves, in violent showers, and their extension is limited 

 to a few miles. 



It appears by Dr. Hildreth's observations, made at Mari- 

 etta, Ohio, for three years past, (published in the Journal of
