COMMON WALNUT. 149 



Jug. r. maxima, with fruit double the size of that of the 

 species. The nuts ought to be eaten in a fresh state, as 

 the kernels shrink up to half their size, when dried. The 

 leaves of this kind are very large, and the tree is highly 

 ornamental, but its timber is inferior to that of the Common 

 Walnut. 



Jug. r. serotina. Where frosts continue late in spring 

 this is a valuable kind, as it does not come into leaf before 

 the end of June, and yet the fruit ripens nearly as early 

 as that of the other varieties. 



Jug. r. tenera, Thin-shelled Walnut. The nuts of this 

 variety have a very thin, tender shell, are fine flavoured, 

 keep longer, and produce more oil than any other kind ; 

 but the trees are generally less prolific. The names of 

 several other less approved varieties may be obtained from 

 the Bon Jardinier and the fruit catalogue of the Horti- 

 cultural Society. 



None of the American Walnuts, or hickory trees, have 

 been long enough introduced, or planted to such an extent 

 in England, as to entitle them to a place in the present 

 work. Most of them produce valuable timber, particularly 

 the Juglans nigra, American Walnut, a considerable quan- 

 tity of which is now imported into Britain.
