BACTEEIAL DISEASES OF PLANTS 



FIG. 300. Olive tree from one of the Department of Agriculture pathological 

 hothouses showing result of an inoculation of Bacterium savastanoi (at X). Ter- 

 minal shoot stunted and many secondary infections, due to slight (natural) wounds 

 and the free use of the gardener's hose. The artificial inoculation was made 

 November 1, 1910, and most of the lower tumors developed the following year. 

 Photographed January 31, 1912.
