WALNUT BLIGHT IBT THE EASTEBN UNITED 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.
