Observations on the year 1827. 

 The past year has been unusually salubrious and fruitful ; 

 the inhabitants remarkably free from diseases, more so than in 

 any year since the first settlement of the country; no vior 

 lent storms or tornadoes, excepting the heavy gale of wind 

 in the afternoon of the 12th April, which continued for six 

 hours, from the west, but without rain ; it swept across the 

 country, from the shores of the upper Mississippi to Vermont, 

 blowing down much timber, and unroofing some buildings. 

 Fruit and crops of grain and grass, have been very abun- 

 dant ; and the air so pure that in warm weather fresh meat 

 kept free of taint, one or two days longer than usual. Early 

 fruits were a week later than in 1826, owing to the diminish- 

 ed temperature in May and June of 1 827, being less by ten 

 degrees than in 1826. The temperature for the year is one 

 degree greater than in 1826 — amount of rain nearly the 

 same. The latter part of September and first of October, 

 Aurora Borealis seen for the first time for many years.
