EASTERN BLACK WALNUT. Juglans nigra. 
The eastern black walnut grows into a massive tree; it is long lived. 
While it is not one of the best ornamentals, it is a good ornamental, 
especially those varieties which retain their leaves late in autumn. 
The black walnut makes a good street or roadside tree, a good shade 
tree about the homestead, a good shade tree for livestock, etc. 
It produces a large amount of edible material of high quality, probably 
as much or more than any other specie of nut tree which can be grown 
in the northern half of the country. Vhe nutritious kernels of the black 
walnut are not only very good raw but they also retain their flavor well 
in cooking. 
The black walnut is one of the most nearly trouble free of any trees, 
not only nut trees but any of the shade or forest trees. It is troubled very 
little by fungous or other diseases and very little by insects. The only 
two insects of much consequence, here in the Northeast, are the husk 
maggot and the walnut caterpillar. The husk maggot is more bothersome 
than injurious to the tree or nut, it tends to cause stain which may pene- 
trate the shell and darken the kernel. The walnut caterpillar is easy to 
control. With young trees the clusters of caterpillars may be removed 
by picking off the few leaves on which they have congregated or when 
they have clustered on the trunk of the tree they may be scraped off 
into a receptacle and destroyed. With larger trees, they are easily killed 
by a stomach poison such as arsenate of lead, D. D. T., Clorodane, Para- 
thion, etc. Of course any poison will work better if applied when the 
caterpillars are small. 
Black walnut grafted trees, if well grown in good soil and not too 
severely pruned, will usually begin to bear the fourth or fifth year after 
transplanting. 
We carry most of the leading varieties. For those not shown on the

with this catalogue.
