tucky, Ohio, Indiana, Illinois, Michigan, Wisconsin, Missouri, Iowa, 

 Nebraska, and Colorado, and as having been reported also from Ger- 

 many, Russia, and the Transvaal. He states that "nothing is known 

 of its occurrence south of Virginia." On account of the low thermal 

 death point of the organism and the lack of reports or specimens of 

 the disease from the States south of Virginia he was rather of the 

 opinion that it would not be found to occur in the far South, except 

 in the more mountainous parts.

In 1914, F. M. Rolfs * reported this disease as causing serious losses 

 to cucumbers in the vicinity of Charleston and Beaufort, S. C. With 

 this exception no published reports of its occurrence south of Vir- 

 ginia and east of the Mississippi River had been found, and letters to 

 experiment station pathologists from North Carolina to Louisiana had 

 given no other definite information. 



Accordingly, during June and July, 1916, a scouting trip was made 

 by the senior writer through North Carolina and South Carolina,
