While the results of these experiments do not show uniformity, 
in most cases a larger area of the rot developed on the fruits 
inoculated on a scab spot than where inoculation was made 
through healthy epidermis. This is probably because more of 
the epidermis is broken by the growth of the scab and the rot 
fungus has a better chance to spread out than where only a 
puncture the size of a needle is made through sound epidermis. 
In all of the artificial inoculations it was observed that the 
rot extended into the fruit much farther than it did in natural 
infections. 
The identity of the fungus produced in all the artificial inocu- 
lations was determined by a microscopic examination; also by 
tasting the diseased tissue. And in many cases cultures were 
made of some of the affected tissue, removed under sterile con- 
ditions, and the fungus reproduced. In nearly every case these 
cultures were absolutely pure,
