News and Notes 



It is well known that practically all of the chestnut trees in and 

 about New York City have been killed within the past few years 

 by the chestnut canker, Diaporthe parasitica; but the number of 

 trees destroyed has been only very roughly estimated. Through 

 the efforts, however, of Mr. J. J. Levison, arboriculturist of the 

 parks of Brooklyn, who has made a careful survey of Forest 

 Park, it is now known that 16,695 chestnut trees were killed in the 

 350 acres of woodland in this park alone. Of this number, about 

 9,000 were between eight and twelve inches in diameter, and the 

 remaining 7,000 or more were of larger size.
