Prof. Snow’s reply: 
“ The rapidity of dissemination of the infection in a field 
depends on the weather and the stages of growth of the bugs, i 
These are very uncertain factors, and for this reason we can- ( 
not determine exactly, or strike an average of the rapidity of 
the dissemination. We would expect marked results in ten 
days after the infection was placed in a field. The chinch bug 
is such an uncertain insect, and is so affected by weather that 
we have been unable to determine definitely in regard to 
many of its habits. We know that the chinch bug will i 
migrate for long distances in one season apparently, and then 
again, we have learned that the chinch bug will not move 
from a given neighborhood for two or three years. We know 
of no instance where the chinch bug has caused sickness in 
cattle, nor have we ever heard of rumors to that effect.” 
Prof. Paul Schweitzer, in an article published in the Rural 
World , makes the following statement: 
“You can distribute these infected bugs from your own 
cages to your neighbors, and they in turn to others, so that 
in a short time a large area of country may be benefited.” 
The circumstances which appeared very remarkable to 1 
me, and strongly favor the theory that this horse disease is a 
result of the distribution of diseased chinch bugs is shown by 
the fact that the counties in which the greatest number of f 
distributions were made are the ones which have suffered the 
most severely with this horse disease. While these distribu- * 
tions, the list of which I present, was made this year, it shows 
that in the previous years distributions were made in the '< 
same counties, and that these were the counties most affected 
with the chinch bug pest. Randolph County had twenty- 
three distributions of infected bugs ; Clinton County, seven- i 
teen; Bond County, sixteen; Marion County, sixteen ; Ma- ’< 
coupin County, twelve. These five counties report the 
greatest number of fatalities among their horses. A few 
reports of a similar disease were sent in from Washington 
County, which had twelve distributions of diseased bugs ; Jef¬ 
ferson County had fourteen distributions; Effingham County, 
eleven ; Madison County, eleven; Shelby County, thirteen ;
