Tennessee, Kentucky, and the south- 

 ern part of Ohio, where the climate 

 is mild, and the soil fertile in an extreme 

 degree. This fertility seems to serve 

 as a substitute for that degree of moist- 

 ure which, in the Atlantic 

 states, seems indispensable to 

 the ash. Where this tree 

 abounds, its wood is used 

 for the flooring and covering 

 of houses; though for shingles 

 it is inferior to that of the 

 tulip tree. Plants of this sort 

 are in the Horticultural So- 

 ciety's Garden, and in Messrs. 

 Loddiges's arboretum ; but 

 they are of no great height. 

 They are readily distinguished 

 from all the other varieties 

 of American ash, as far as 

 we have been able to observe 

 these in the neighbourhood of London, 

 by the bark of the trunk, which cracks 

 and separates at the edges into thin 

 plates, much in the same way as that 



of the white American oak (Quercus alba). The price of plants is 2s. each, 



and of seeds 4s. per quart.

Description, fyc. The green ash is easily recognised by 



the brilliant colour of its young shoots ; and by its leaves 



being nearly of the same colour on both surfaces. From 



this uniformity, which is rarely observed in the foliage of 



trees, Dr. Muhlenburg applied the specific name concolor ; 



and Michaux gave this tree the popular name of the green 



ash. The leaves vary in length from Gin. to 15 in. with 



from 2 to 4 pairs of leaflets, and an odd one, according 



to the vigour of the tree, and to the coolness of the soil in 



which it grows. The leaflets are petiolated, and distinctly 



denticulated. The seeds are small ; and the tree does not 



attain a great size. The green ash is more common in 



Pennsylvania, Maryland, and Virginia, than in any other part 



of the United States ; but it is much less common than the white ash and black
