THE WALNUTS 



The walnuts (genus Juglans) form a noble family of ten 

 species, in which there are no "black sheep" and this is remark- 

 able in any family. Each species yields valuable wood, and 

 sweet, edible nuts. Each one deserves planting as an ornamental 

 and shade tree. 



Our American forests show four species two spread over the 

 eastern half of the continent, one grows in the Southwest, and 

 one in California. To these have been added valuable exotic 

 species. The English or Persian walnut (Juglans regia) is grown 

 in the Southern States and in California; and two Japanese 

 species, /. Sicboldiana and /. cordijormis, both of the butternut 

 type but vastly superior to it, thrive in the regions where the 

 English walnut is not hardy. There is also a Manchurian species 

 in cultivation here. One or more walnuts belong in the West 

 Indies and South America.
