Fic. 29. 
Infected nursery trees removed from the Zodlogical Park to the Garden 
last autumn. The photograph was taken August 27,1906. The dead tree on the 
right was apparently in perfect condition early in the season, but close inspection re- 
vealed a diseased spot near the base of the trunk, which later girdled it and killed 
the entire tree. 
The tree on the left also leafed out vigorously and appeared healthy, but was 
girdled about halfway up the trunk by May 15 from a diseased spot near a wound 
made in pruning. On May 149 fruiting pustules began to appear on the diseased bark 
and the leaves began to die.
