pntting out considerable wheat : and I was at that time considerably troubled aboat 

 the bugs in my corn, thinking that if I put out any wheat at all it would be destroyed 

 by bugs: but, thanks to you, my wheat is now safe from bugs, at least those that 

 were on my place before sowing my wheat. I only wish I had written to you sooner 

 than this. 



I will send by express one bottle of bugs that I gathered after they commenced 

 to die.

The following report from R. L. Stangaard is inserted as being of a 

 more scientifically circumstantial character than most of the other re- 

 ports : 



Florence, Kansas, August 22, 1890. 

 Prof. F. H. Snow. 



Lawrence, Kansas: 



Dear Sir : In reply to your favor of July 27, last month, would say that infected 

 bugs were applied after they were kept with live ones about 42 hours. They were 

 applied as follows : 



Most of the bugs mixed were dead when taken out of the box. They were applied 

 in seven different hills, being put into every ninth hill. I marked every hill with a 

 number so as to be better able to watch the progress. 



Examined after 46 hours aijplication with the following results : No. 1, mostly dead; 

 No. 2, bugs mostly alive, seemingly very restless; No. 3, bugs seem to be sick; No. 

 4, bugs mostly dead (on hills around the bugs seem restlessj ; No. 5, not exam- 

 ined (on hills around it the bugs seem to be affected, sick). Examination 8 days 

 after application with the following results, to wit : No. 3, bugs seemingly in a dying 

 condition. On the hills around it the bugs seem to be well, with exception of one 

 hill, where they seem to be dying and some dead. No. 4, not a live bug in the hill. 

 No. 5, apparently dying, also dying in the hills around this. No. 6, bugs dying in hill. 

 No. 7, apparently not dying. 



On August 16, 12 days after application, I found the bugs to be dying and dead all 

 through the field (12 acresj. 



On August 20, I again found the bugs to be dying rapidly. A field, being 40 rods 

 distant, had sure marks of bugs in a dying condition. What I mean by bugs being 

 in a dying condition is this: They lay on their backs, almost motionless, and others 

 lay in same position, moving limbs violently. 



This remedy was applied on A. G. Rosiere's farm, on Bruno Creek. Marion County, 

 Kansas, being 9 miles east and 3 miles south of Marion. 



Thanking you for your favors, I remain, yours, truly, 



R. L. Stangaard. 



October 16, many of the bugs were dead ; the others apparently 

 lively. The dead bugs were found to contain hyphal bodies similar to 

 those with which they were infected. A live chinch bug from the same 

 jar was crushed and found to contain round hyphal bodies ; but these 

 refused to germinate. 



November 5, not all of the bugs are yet dead. The few remaining are 

 apparently lively. 



The following is a summary of the results of the field experiments in 

 the season of 1890 : 



Number of boxes of diseased bugs sent out, thirty-eight. Seven of 

 these lots were either not received or received and not used. Reports
