in a plantation five years old. The owner states that it occurs 
chiefly in old plantations, those two and three years old usually 
being exempt. It is worst on high ground and occurs in wet 
seasons as well as dry ones. The canes commenced to die about 
the time the fruit began to ripen. Often the entire cane was 
affected, but frequently only a part of it. Healthy and diseased 
branches occurred on the same cane. Sometimes a cane would 
be dead upon one side and in a semi-living condition upon the 
other. The pycnidia of the Phoma were to be found on almost 
every affected cane, and where one was killed back only part way 
the pyenidia would be clustered just above the boundary between 
the living and the dead tissue. 
At Voorheesville the disease was noticed attacking also red 
raspberries of the variety Outhbert. Berries, leaves and wood 
suddenly dried up while the fruit was ripening. Usually, but not 
always, the wliole cane was affected. At some point on the cane 
there were numerous pycnidia of the same Phoma found on black 
raspberries. When only a portion of a cane was affected the 
pycnidia were commonly clustered (as on black raspberries) just 
above the boundary between the diseased and healthy bark. On 
the red raspberry the pycnidia appear to the unaided eye some- 
what different from those on the black raspberry. 
A disease having the same symptoms attacks the Marlboro, a 
red variety extensively planted in the Hudson Valley. On this 
variety it is especially destructive and is everywhere known as 
_ “the Marlboro raspberry disease.” A bad case of this was observed 
at Delmar, but the examination was so hasty that little can be said 
concerning it. It is certain, however, that the Phoma was not 
so abundant as in the previously mentioned cases. At this place 
the yellow variety, Golden Queen, was also attacked by it. 
At West Sand Lake it was destructive on the variety Shaffer, 
being worse in the older portions of the plantation. Correspond- 
ents report it from various other localities. It is a widespread and 
destructive disease.
