dere, it was observed that nearly every plane-tree was so badly 

 affected as to suggest that a hard frost had visited the region. 

 This contagious fungous disease is so prevalent as to discourage 

 the use of this tree for any sort of planting, and, while it might 

 be held in check by spraying, the trouble of spraying is too great 

 to warrant the use of fungicides. 



The second forest tree disease, much complained of, is a stem 

 blight of the Chestnut, due to Diaporthe parasitica, recently 

 studied by Professor W. A. Murrill, who affirms that it enters 

 the stem, often through wounds, and spreading beneath the outer 

 bark may girdle the tree. The infested parts bear many pimples 

 where the spores are produced in large numbers. As the fungus 

 works so out of reach of remedies it is recommended to remove 

 all badly-infested trees and refrain from planting young chest- 

 nuts in localities where the disease is troublesome. 



General Notes. 



Among orchard troubles the pear twig blight, peach curl and 

 apple fruit rot have been somewhat in evidence. In the fruit 

 garden complaints have been made of the rust of the blackberry^ 

 anthracnose of raspberry, blight of strawberry and, among truck 

 crops, the potatoes (both white and sweet) have had their rots 

 and blights. Tomatoi growers in parts of the State have suffered 

 from a leaf disease, and the cranberry growers, while still having 

 •their crop shortened by "scald" and "rot," are learning to spray 

 against them with good results.
