PLANT BACTERIA, VOL. 2. PLATE 14. 
Wilt of Cucurbits. 
Cucumber-plants inoculated with B. tracheiphilus in summer of 1903 (hothouse, U. S. Department of Agriculture, 
by James Birch Rorer). 
Infections were by means of needle-pricks, using pure cultures. In each case needle-pricks were confined to a single leaf-blade. This blade 
, first wilted and then gradually all the other leaves. Inoculations were made on July 23 and photograph about 18 days later. Much 
reduced.
