GALL TO HUMAN CANCER* 
Tue disease on which I shall speak to- 
day is known in this country as crown-gall, 
because it has been observed most fre- 
quently on the crowns of trees and shrubs, 
but it is not peculiar to thissituation. It oc- 
curs also on roots and shoots. This disease 
has been known to cultivators and to plant 
pathologists for many years and has caused 
more or less injury to a variety of plants 
both in this country and in Europe. Of 
plants subject to serious injury may be 
mentioned: Roses, almonds, peaches, rasp- 
berries, grapes. Sometimes the plants are 
only dwarfed or crippled, at other times 
killed. Recovery, especially in certain 
species, is frequent. In Italy the attacked 
grape vines are said to live about four 
years. 
It has been ascribed to a variety of 
causes, @. g., frosts, wounds made in culti- 
vating, insect injuries, fungous injuries, 
physiological disturbances, ete. The actual 
cause was not known until discovered by 
the writer and his associates. Team work 
on this disease has been carried on in the 
U. S. Department of Agriculture for the 
last eight years, 7. ¢., since February, 1904. 
The first successful pure culture inocula- 
tions were obtained in 1906. The organism 
was described and named by us in 1907.”
