A TREATISE ON NUT CULTURE. 



WALNUTS (Juglans.) 



Of the Walnuts of commercial value in the United States there are the 

 Black Walnut (Juglans Nigra} t and the Butternut (Juglans Cinerea } , which are 

 natives of this country. 



The Persian Walnut (Juglans Regia], and the Japanese Walnuts. 



Native The Black 



Walnuts. walnut 



and But- 

 ternut have not been grown in or- 

 chard form to any extent, though 

 they have been planted extensively 

 for timber purposes. 



Tree, when standing alone, with 

 room to develop, makes a large, 

 spreading, handsome tree, with BUTTERNUT, 



odd, pinnate leaves ; leaflets from fifteen to twenty-one, mainly oblong and 

 pointed ; male and female flowers on the same tree ; fruit, round or oblong ; 

 husk, thin, drying up with opening the husk ; shell, rough and thick ; kernel, 

 fleshy, rich and oily. They are found pretty generally throughout the United 

 States, except the Gulf and Southern Atlantic Coast, preferring low, moist, 

 rich, loamy ground. 



Propagation There have been but few attempts to propagate any 

 distinct varieties of Black Walnut or Butternut by 

 budding or grafting, as there appears 

 to be less variation from seed than 

 with other nuts and fruits, and but 

 few varieties of superior qualities 

 have been discovered. 



They are used to some extent on 

 which to graft the Persian Walnut, 

 and the mode generally adopted is 

 the cleft-graft, with fair success. 



Gilbert. From H. K. Gilbert, 

 Columbus, N. J. Tree young, good 

 grower; very productive; nut very 

 large, round; shell thin; kernel full, 

 plump and good quality.
