2) Direcror’s Report of THE 
canes in autumn and which were formerly mistaken for the early 
stage of cane blight certainly have no connection with the disease, 
but, instead, they seem to be due to a comparatively harmless 
fungus, Sphaerella rubina. 
Spraying experiments with cane blight are in progress. Thus 
far it has not been ascertained what can be accomplished by 
Spraying the new canes, but the experiments show that it is 
useless to spray the fruiting canes with bordeaux mixture. 
In a plantation of Cuthbert damaged about 25 per ct. by cane 
blight, rows sprayed three times in the spring gave an average 
vield of 18514 pints while the average yield of unsprayed rows 
was 20314 pints. . 
The new apple rot.— In the autumn of 1902 there was a remark- 
able epidemic of apple rot in New York State caused by a com- 
mon fungus, Cephalothecium roseuwm, which has been known to 
scientists for over sixty years and during all that time supposed 
to be harmless. Inoculation experiments show that the fungus 
is unable to penetrate the uninjured skin of apples, but that when 
the skin is once broken by other agencies it is capable of causing 
rot. in the present case it took advantage of breaks in the skin 
made by scab. 
Since only secabby apples were attacked by the rot the trouble 
might have been prevented by thorough spraying to prevent 
scab. .in cold storage the fungus, although not killed, does no 
damage. Unsuccessful attempts have been made to prevent the 
decay of slightly affected apples by dipping them in solutions 
of copper sulphate and formalin of various strengths. Briefly 
stated, the proper treatment for this new apple rot is, to spray 
thoroughly and place in cold storage as soon as gathered. 
DEPARTMENT OF ENTOMOLOGY. 
The investigations upon the origin and early stages of sexual 
and parthenogenetic eggs of aphids are being continued. A series 
of observations upon the fly-resisting qualities of about 30 
varieties of wheat planned for the past season were carried out 
only in part owing to the scarcity of the Hessian fly.
