cally disappeared in the fields of Mr. Briggs, Mr. Hoath, and Mr. Wiley, 

 where the disease had already had time to do its work, in the field of Mr. 

 Morris the bugs were still in force. I found on the farm of Mr. Strickler, 

 where the infection had been in his corn field for five days, that the bugs were 

 dying rapidly. I could find large numbers of Sporotrichum-covered bugs 

 under the clods and fallen corn stalks. That part of Mr. Strickler's field 

 where the disease was at work was only separated from the farm of Mr. Morris 

 by a road and small uncultivated field. 



To sum up: In no field did I find all the bugs exterminated by the dis- 

 ease. In all of the fields where the infection had been working for two weeks, 

 the bugs had so greatly decreased in number as to be hardly worthy of note. 

 In one field where the infection had been only a few hours the bugs were still 

 in force. In another field where the the infection had been scattered five 

 days previously the bugs were rapidly dying, and the dead bugs were covered 

 with a vigorous growth of Sporotnchum. 



Respectfully submitted, W. C. Stevens.
