possible to do it without damaging the kernel so 
much as to prevent its germination. The nuts are 
sweet, but have a peculiar flavor, which is relished by 
some and very disagreeable to others. Varieties 
sometimes occur of superior flavor, which would 
seem to indicate that the fruit is capable of improve- 
ment. 
3. Juglans regia—English Walnut. 
Leaflets, five to nine, oval, glabrous, obseurely- 
serrate; fruit, oval, upon a short peduncle. 
The English Walnut is a large tree, and is much 
cultivated in Europe, both for its fruitand its timber. 
Its fruit is largely imported, and sold in all parts of 
the country. Asa timber tree, it is inferior to the 
Black Walnut—as an ornamental tree, to both that 
and the Butternut; yetit merits cultivation for the 
sake of its fruit, wherever the climate is not too severe. 
The tree is not hardy in Northern INinois, and it is 
doubtful if it would succeed in the central parts of 
the State. Probably it might do well in the latitude 
of St. Louis. There are trees near the city of New 
York which bear fruit, but in the interior the blos- 
soms are often destroyed by spring frosts, in latitudes 
where the tree withstands the winters. ‘The best 
varieties are propagated by grafting. Like the Black 
Walnut, its neighborhood is said to be injurious to 
other trees, and the exhalations from it are so power- 
ful as to affect disagreeably those who sleep in its 
shade.
