in northern Ohio ; and the Belmont, which has been pro- 

 nounced the most valuable of all apples at Cleveland, is un- 

 worthy of cultivation at Cincinnati. These changes in 

 the latter instances, may perhaps be ascribed to a difference 

 .in soil ; and the application of special manures, as lime 

 potash, &c., on those unfavorable soils, has improved the 

 quality. The periods of ripening, given in the foilowinfr 

 pages, are intended to apply to the northern states. A dif- 

 erence of about two or three weeks exists between fruits 

 cultivated at Boston and Rochester, and in central Ohio and 

 southern Pennsylvania and other differences of latitude 

 nearly m the same ratio.
