Meteorological Journal at Marietta, Ohio, for 1844. 289 



The mean temperature for the spring months was 55°-91j 

 which is ahiiost ten degrees greater than the spring of 1843, and 

 approaching nearly to the temperature of 1842. The most 

 marked difference was seen in the months of March and April. 

 In the former month the excess was 14°-52, and in the latter 

 nearly ten degrees. In May the variation was three degrees. 

 The early progress of spring produced a corresponding growth in 

 trees and plants, but not at so rapid a rate as in March, 1842, 

 which was ten degrees warmer than the same month in 1844, 

 and twenty four degrees than March in 1843. The mean of the 

 spring of the two former years varied only l°-20 ; that of 1842 be- 

 ing 57°-ll, which is the highest of any one on record for the last 

 twenty years, or probably since Marietta was settled. From my 

 floral calendar it will be seen, that the progress of vegetation in 

 March was not so rapid, but that the deficiency was made up in 

 April, which shows a heat of nearly two and a half degrees greater 

 than that of the corresponding month in 1842. The following 

 list of the periods of blossoming of well known plants and trees, 

 and the ripening of fruits, will be interesting to the botanist and 

 to the lovers of horticulture in the valley of the Ohio, if not in 

 the Atlantic states, when compared with those in the same par- 

 allel of latitude east of the Allegheny ranges.
