which the Japanese walnut was used was made a 
few seasons later. The results, as regards the pro- 
duction of nuts, have been sufficiently detailed. 
Up to the present no variety of commercial value 
as a nut bearer has been produced, although the 
indirect influence of the hybrids on the Persian 
walnut industry, through their use as stocks, has 
been quite notable. 
THE BUTTERNUTS 
There is a very near relative of the black wal- 
nut, known as the butternut, that was formerly 
well-known in most forest regions of the eastern 
United States. 
The two trees are of closely similar appearance, 
and the nuts have the same characteristic thick 
and corrugated shell. The butternut, however, is 
oval in shape, whereas the walnut is nearly round. 
The meat of the butternut is also somewhat richer 
in quality, and it is generally regarded as superior 
in flavor. The meat itself, indeed, is by many peo- 
ple regarded as superior to that of any other nut. 
The difficulty is that the shell, like that of the black 
walnut, is very thick, making it difficult to extract 
the meat without breaking it. 
The butternut thrives generally where the black 
walnut does. It makes a more spreading tree, but 
the wood is softer and far inferior for cabinet 
purposes.
