The mean temperature for 1848 is 52° -50, which is very near 

 the usual degree of heat for this place, and accords with that 

 of our wells and springs, which are allowed generally to be cor- 

 rect tests of the mean heat of the year. The mean indicated by 

 the thermometer varies a degree or two in different years, owing 

 to very hot summers, or extreme cold winters ; rising as high as 

 54° for some years, and sinking as low as 50° for others, forming 

 quite a variety in a series of years. 



The amount of rain and melted snow was forty-three inches 

 and eighteen hundredths, while in 1847 it was fifty-two inches 

 and thirty hundredths, this being the year of the great flood in the 

 Ohio river, in the month of December. Heavy rains attended the 

 winter solstice this year, as they almost invariably do at this 

 period, every year: wet weather is much more certain at this 

 period than at the equinox. 



The mean temperature for the winter months was 36°-ll, for 

 the spring 52°-59; summer 69°-10, and for the autumnal months 

 49°-70. 



The year which has just closed has been rather remarkable 

 for its equable temperature. The greatest cold was at 3° above 

 zero, on the tenth of January ; and the greatest heat at 89~ 

 on the 27th of June. In July, August and September, it sel- 

 dom rose above 80° in the hottest season of the day, doing so 

 only on eighteen days ; while in the year 1846, it rose above 

 this point on fifty-nine days, standing at 91° and 92° several
