40 SHADE TREES FOR NORTH CAROLINA. 



Walnuts (Juglans). — In addition to the native black walnut, which 

 is a very desirable roadside tree, there are several foreign walmits which 

 yield nuts of a better quality. 



Black Walnut (Juglans nigra) can be planted along the roads in any 

 portion of the State. It is advisable to plant the trees in the places where 

 they are to remain, since it does not bear removing at all well on account 

 of its deeply seated tap root. Very large and thin-shelled nuts should be 

 selected, as the nut of the black walnut is capable of considerable im- 

 provement. Walnut trees should be spaced 45 feet. 



English Walnut is not hardy further west than Salisbury. In the 

 eastern part of this State, it makes a medium sized tree and should be very 

 generally planted, even if only seedlings are raised. These latter are in- 

 ferior in the quality of their nuts to grafted stock secured from nursery- 

 men. 



Two hardy Japanese walnuts are being offered by southern nurserymen 

 which are superior in the quality of their nuts to our native species, al- 

 though much inferior to the English walnut. One of these is the Juglans 

 cordiformis, whose nut bears much resemblance to the butternut. It is 

 thin shelled and the kernel can be removed entire. It makes a large tree, 

 forming a tap root and is hardy in the eastern two-thirds of this State. 

 The other, Juglans sieboldia-na, which is a native of the mountains of 

 Japan, and which will probably be hardy in the mountains of this State, 

 is a smaller tree with a root system of many deep-seated roots and fibrous 

 rootlets. The nuts, which are borne at an early age in large clusters, are 

 of superior quality, about the size of those of the black walnut but with 

 much thinner shells. The nuts of both species can be secured at reason- 

 able prices. For trees suitable for very dry or wet places see p. 72. 



AEBOR DAY. 



It is not inappropriate to refer to the observance of Arbor Day by 

 schools and its true field of usefulness in this State. 



While the same sentiment which is attached to the observance of Arbor 

 Day in the scantily forested western states cannot be applied in a well 

 wooded State like North Carolina, yet the observance here of such a day 

 has its significance. Arbor Day in North Carolina could be set aside for 

 the school children to learn of the great natural gift which we have in the 

 forests, and the relation of the forest to the well-being and wealth of our 

 people.
