PRACTICAL FOKESTRY. 



that do succeed here, I can see no good reason why this nut 

 should not be raised in abimdance in most of our Northern 

 States. Recently a dwarf French variety, called the "Prepar- 

 turiens," has been introduced and largely projiagated by our 

 nurserymen, as it is said to come into bearing when quite 

 young. There is a very large number of varieties cultivated 

 iu the French and other European nurseries, the nuts varying 

 greatly in size and form, as shown in the accompanying illus- 

 trations, which I have selected merely to give the reader an 

 idea of the extremes of variations to be found among the nuts. 

 The Small-fruited Walnut (t/?fgrZajiS regia microcarpa), shown 

 in fig. 38, is only about one-half inch in diameter, but the ker- 

 nel is sweet, and of a most delicate flavor and texture. This 

 is probably the smallest variety known, wliile the Gibbou's 



41. — CUT-LEAVED WALNUT. 



Walnut {J. regia Gibhosa), fig. 39, is quite the opposite or the 

 largest, and while it has a rather thick shell, the kernel is of 

 excellent quality and easily extracted. The Barthere Walnut 

 {J. regia Barthereana), fig. 40, is remarkable for its extreme 

 length. Its shell is quite thin, and the flavor of the kernel is 

 excellent. Between these extremes of variation there are 

 scores of others that are quite distinct, and may be found de- 

 scribed in the catalogues of European nurserymen. There is a 

 also a marked difference iu the habit of growth of the differ- 

 ent varieties, some being very tall trees, and others dwarfish. 

 There are also broad-leaved and narrow-leaved varieties, and 

 among the latter the pretty Cut-leaved Walnut {J. r. laciniata), 

 fig. 41.
