WALNUT BLIGHT TS THE EASTERN UJTITED STATES. 7 
ence in infection periods may alter results, but from the best infor- 
mation at present available it appears that the solution of the problem 
of the control of this disease rests in the development of immune or 
highly resistant varieties. Nurserymen and growers should be on the 
watch for such sorts as combine a high resistance to this disease with 
the other qualities necessary in a good commercial nut, and whenever 
such varieties are found they should be propagated. 
The wide planting of small lots of trees will furnish in the course 
of a few years valuable suggestions as to the requirements and range 
of the Persian walnut in the Eastern States, and should not be dis- 
couraged on account of blight. Although it is not possible at this 
time to say that this nut has large commercial possibilities in the 
section east of the Rocky Mountains, it is equally impossible to state 
the contrary as the fact. It is well established, however, that there 
are now hundreds of seedling trees in New York, Pennsylvania, New 
Jersey, Delaware, and Maryland bearing nuts of more or less merit 
despite the presence of this disease, and apparently there is no reason 
why every farm and country home in this district should not have a 
small planting of these productive as well as highly ornamental trees*
