a dozen bugs from No. 54, this series. The box was kept on the 
damp floor of a cider house. Bugs enveloped in the white fungus 
were removed every fourth or fifth day, and live insects and fresh 
food were added as required. This box was kept in active use until 
about September 1. It was examined by Mr. Johnson September 27, 
at which time, although the insects were all dead and the food 
was dried up, it was still in good condition, and about a hundred 
chinch-bugs thickly imbedded in the muscardine fungus, were taken 
out and given to Mr. Filson for future use. Several hundred fungus- 
covered bugs from this box were distributed in corn along the 
north and south sides of a field on Mr. Filson’s farm about July 
1, and about ten other distributions were made at regular inter¬ 
vals after a rain or on damp mornings, with bugs from the same 
source. Chinch-bugs entered this corn from an adjoining wheat 
field, literally covering the stalks in many places. This field was 
examined about every third day, but no trace whatever of the 
white fungus was detected. As a consequence, this experiment 
was abandoned, and other measures were taken by the owner to 
arrest the ravages of the chinch-bug (see No 89). Mr. Johnson 
examined this field September 27 and again October 6, but did 
not find a single infected insect. The corn had been cut at the 
time first mentioned, but the bugs were still quite abundant in the 
shocks, and foxtail and other grasses along the fences and in low 
damp spots throughout the field were thickly covered by them. 
Several fungus-covered bugs were found by Mr. Johnson Sep¬ 
tember 27 in grass along the roadside more than a mile from 
Mr. Filson s farm, and again on the Filson farm also during the 
latter part of November. December 10 Mr. Filson writes“I 
could see no effect of the disease on my farm until after the 
recent rain. At the present time I find chinch-bugs covered with 
fungus in all the shocks in corn adjoining timber.”
