Japanese Walnuts. 



The Japanese Walnut is known to occur in Canada in three dif- 

 ferent forms — Juglans cordif ormis ; Juglans Sieboldiana ; Juglans 

 mandschurica. 



Juglans Cordif ormis. 



This species is cultivated extensively in Japan and is the most 

 valuable one for Ontario. The tree is very beautiful, comes into 

 bearing early, bears heavily, grows rapidly and is reported to live 

 to a great age. It is believed to be as hardy as the black walnut and 

 ought to do well wherever the native walnut grows satisfactorily. In 

 the best types the nuts are distinctly heart-shaped, have a thin shell, 

 crack easily and contain a large kernel of good quality which can 

 often be removed almost entire from the shell with a light tap from 

 a hammer. 



There are two fine heartnut trees growing near Aldershot which 

 is near Hamilton on the road to Toronto. These trees are eight years 

 of age and are about twenty-eight feet tall with a trunk diameter of 

 eight to nine inches. In the seventh year one tree produced about a 

 bushel of fine nuts with thin shells. 



Juglans Sieboldiana. 



This type was first introduced into the United States about 1860 

 by a Mr. Towerhouse in Shasta County, California. Since then it 

 has been widely distributed arid is now found in many parts of the 

 United States and Canada. It is much the same in appearance as the 

 one first described and grows just as rapidly and bears just as early 

 but does not produce so valuable a nut. The nut has a smooth shell 

 of medium thickness with a kernel of good quality. It does not 

 usually crack easily and the kernel cannot be taken out entire, there- 

 fore, is not so desirable as the cordiformis type. In rapidity of 

 growth the Japanese walnut is only excelled by the willows and pop- 

 lars. In the vicinity of Grimsby there is a tree eight years of age 

 which is about twenty-five feet high and has trunk diameter of 

 seven inches at the base. It began to bear nuts in the third year and 

 in the sixth year produced one bushel. 



Juglans Mandschurica. 



The general growth characteristics of this species are somewhat 

 similar to the other two types but the nut, however, is quite different, 

 being somewhat like a butternut. Because of this it is sometime? 

 called the Japanese butternut. It is the least desirable of the Japan- 

 ese group and should not be planted except where the cordiformis 

 type will not grow. 



Chinese Walnuts (Juglans regia sinensis). 



The Chinese walnut is being grown experimentally in the north- 

 ern part of the United States and has been tried at only one place
