second year, about thirty per cent show banded stem fasciation 

 with, however, a wide range of variation. 



In Cichorium Inlybiis the heredity cjf fasciations has been 

 studied in two generations of pedigreed plants. From a cross 

 between two fasciated plants and Fi progeny twelve plants were 

 all fasciated, and of the F2 generation of eighty-six plants all but 

 eight were fasciated in some degree. The fasciation here is of 

 the grooved stem type, and exhibits a great range of variation. 



The concluding number on the program was given by Miss 

 Margaret Slosson, "The Identity of Trichomanes pyxidiferum L." 



Many specimens and photographs were exhibited in illustrating 

 the characteristics of this species.

 hickories and oaks are now threatened by a similar fate but from 

 a very different and preventable cause, viz., the attack of two 

 species of native insects, the habits and seasonal histories of 

 which and methods of control are known. These methods are 

 simple and inexpensive and their efficiency has been demon- 

 strated. A preliminary survey of Long Island has been under- 

 taken by this department to determine the distribution of these 

 insects as serious enemies of the trees and to give free instructions 

 to interested local owners on practical methods of ending the
