The mean temperature is over half a degree below that of 1849. The cause of this ine- 

 quality is found in the low grade of the spring and autumnal months ; the mean of the 

 spring being nearly five degrees less than that of 1849, while autumn is about one degreo 

 less. The summer was warmer by nearly one degree and a half. The greatest heat was 

 in July; the mean o*f the month being 76.14 degrees, while July, 1849, was 72.20 degrees. 



In 1849, the Peach was in flower on the 7th of April; Imperial Gage and Morillo Cherry 

 on the llth ; Pear, on the 12th ; and the Apple on the 27th. In 1850, the order was thus : 

 Peach, April 22d ; Gage and Cherry, the 23d ; Pear, the 27th ; and Apple, the 2d of May. 



The amount of rain and melted snow is 9. IS inches more than in 1849, when it was 43.18 

 inches, and is above the average for this climate, eight or nine inches. Crops of all kinds 

 were abundant in Southern Ohio, fruits as well as grain.
