New York AGRICULTURAL EXPERIMENT STATION. LA 
In this experiment the symptoms of the inoculated plants were 
like those of naturally infected plants, but the progress of the 
disease was slow. It may be that Mohler is more resistant than 
some other varieties. 
Eaperiment No. 3.—- Date of inoculation, June 8, 1901. Five 
new canes of red raspberry (variety, Pride of Geneva) were inoc- 
ulated with a month-old culture, the source of which was isolated 
May 1, 1901, from black raspberry. The canes, which were 24 
to 30 inches high, were inoculated 6 to 8 inches below the tip 
by abrading the bark, applying a bit of fungus and winding the 
whole with grafting wax as in Experiment No. 1. Five check 
eanes were abraded and wound with wax in the same manner 
but without application of the fungus. 
On August 28 four of the inoculated canes showed more or 
less discoloration around the wax while the remaining cane 
seemed normal. None of these canes showed any wilted foliage. 
At the same date three of the checks were free from all signs of 
infection, but the other two had pronounced discoloration of the 
bark around the wax as on the inoculated canes. Thinking that 
the checks had become naturally infected by the fungus, which 
was very common among the plants of this variety, the experi- 
ment was abandoned and no further observations were made. 
Consequently, the ultimate results are not known and the experi- 
ment teaches nothing except that variable results from inoculation 
are to be expected. In 1901 new canes of this variety, inoculated 
in the same manner, were dead within two months after inocu- 
lation. (See Experiment No. 1, page 115.) 
EHaperiment No. 4.— Date of inoculation, June 8, 1901. Five 
new canes of blackberry (variety, Taylor) were inoculated in the 
same manner and with the same culture as that used on red rasp- 
berry in Experiment No. 38. The canes were about 30 inches 
high and inoculated 6 to 8 inches below the tip. There were 
five checks. | 
On August 28 there was no discoloration of the bark around 
the wax and no other evidence that the inoculation had had any 
effect whatever.
