leaves throw out a powerful aromatic smell, es- 

 pecially when bruised and in hot weather. 



The bark is of grey colour and smooth in 

 the young tree and branches, but as the tree 

 gets older, it becomes rugged. The walnut is 

 propagated by its nuts. 



Previous to the importation of mahogany, the 

 wood was much valued for furniture. With age 

 it is a beautifully grained dark brown, shaded 

 with black. Easily worked and not liable to split, 

 it takes a fine polish, and has the advantage of 

 being light ; the more ornamental pieces of its 

 wood lie generally near the roots. 



The American species, J. nigra, is imported 

 for its wood, and is much larger than J. regia. 

 The hickories, which are closely related to the 

 walnut, are not much cultivated in this country. 

 The climate is not suitable to them ; still, in 

 favourable spots, they are occasionally met with. 

 There are two fine specimens, quite fifty feet high, 

 growing in the grounds at Ham.
