AGRICULTURAL EXPERIMENT STATION. 91 



Do you think that the Bordeaux mixture would prove effectual, 

 both to cedar and quince? I do not wish to remove my hedge. 



Kespectfully, 



M. B. Whiting. 



We also received through Hon. B. Walker McKeen specimens of 

 this same disease accompanied by the following letter from Mr. 

 Dennett. 



North Berwick, Me., July 15, 1894. 



Blr. Secretary — Inclosed I send for your inspection, a growth I 

 find upon three quince trees, I bought from New York nurseries, 

 and set last spring. One each of three varieties, Fuller, Alaska 

 and Meech Prolific. They have started finely, but upon almost 

 every twig there is a growth of this kind. I do not understand it, 

 for it has never appeared on our Orange and Champions/^that we 

 have had growing for years. Do you think it is anything like the 

 black knot of plum trees that should be destroyed to prevent it from 

 spreading ? The trees have started thriftily, but it looks as though 

 this would work their destruction. Can you please tell me what 

 should or can be done with them ? I dislike to destroy them unless 

 it shall be necessary. 



Very truly yours, 



John A. Dennett. 



In answer to some questions regarding the occurrence of cedar 

 trees near Mr. Dennett's orchard we received the following, which 

 strengthens the belief that the nursery stock was infected. 



North Berwick, Me., February 5, 1895. 

 Prof. F. L. Harvey: 



Dear Sir — In answer to your esteemed note of 29th ult., will 

 say that we have no cedar growth in this vicinity within miles of 

 us, neither do I know of any cedar ornamental growth or hedges 

 about here. The unaffected Orange and Champion were older 

 trees which had been set several seasons, this fungus attacked the 

 new set quince that I had from New York and New Jersey 

 nurseries, (Green's and Lovett's,) hardly a twig of which escaped. 

 I took the precaution to cut off and burn all the fungous growth and 

 if it should appear again this season I will report to you, as it was 

 entirely new to me and of which I am entirely unacquainted. 



Very truly yours, 



John A. Dennett.
