118 REPORT OF THE BOTANIST OF THE 
EKaperiment No. 5.-— Date of inoculation, June 18, 1901. Ten 
new canes of Lucretia dewberry were inoculated with a fourteen- 
day-old culture descended from the culture used in Hxperiment 
No. 3. Six to eight inches below the tip the canes were slightly 
abraded, a drop of water placed on the wound, then the fungus 
applied and the cane wound with grafting wax in the customary 
manner. There were ten checks. 
On September 12, 1901, there were no signs that inoculation 
had had any effect. Final observations were made on May 8, 
1902, at which time all ten checks and nine of the inoculated 
canes were found to have been winter killed, with no sign of 
Coniothyrium about them. However, the tenth inoculated cane, 
although alive both above and below the wax, was partially dead 
at the point of inoculation and covered with Coniothyriwm 
pycnidia underneath the wax. It appeared as if infection may 
have occurred on this cane. 
Experiment No. 6.— Date of inoculation, June 14, 1901. Ten 
new canes of red raspberry (variety, Coutant No. 1) were inocu- 
lated 6 to 8 inches below the tip with the same culture used in 
Experiment No. 5. The fungus was producing spores abund- 
antly. The method of inoculation was by abrasion of the bark, 
application of a drop of water and a bit of fungus and the whole 
covered with grafting wax. The canes were 26 to 30 inches 
high. There were ten checks. 
On September 2, 1901, all of the inoculated canes (except one 
broken by the wind July 10) and all of the checks were alive and 
apparently little worse for inoculation. There was only a little 
discoloration of the bark around the wax but the canes were 
somewhat enlarged and cankers were forming. 
On May 7, 1902, only three of the inoculated canes were alive 
above the wax and these were badly cankered. Four had 
broken off at the point of inoculation and the tops had disap- 
peared. One other cane was all dead above the wax, with 
Coniothyrium pycnidia, and one had been broken, accidentiaily, 
eight inches below the wax. The tenth cane had been broken 
by wind the previous July. At this date nine of the checks 
were alive and apparently normal except fer being somewhat
