56. The first three rows on the south, east, and west sides were 
treated as above. Examined by Mr. Wells June ‘25. No indica¬ 
tions that the disease was spreading. 
A third distribution was made June 30. About one quart of 
chinch bugs, dead and alive, from same source as the others, were 
scattered, as above, in the second, third, and fifth rows on the 
west and north sides. Mr. Wells examined field July 5, but found 
no bugs dead with the fungus, save a few scattered fragments of 
the original material. Mr. Marten examined it (B), as well as 
neighboring fields (D and F), July 11. No traces of the disease 
■were found at this time on this farm, except a few weathered 
specimens in wheat (A), as noted in experiment 55. All the corn 
on this farm was dwarfed and ragged. The bugs were everywhere 
abundant, covering the stalks in many places throughout the fields. 
The fourth, and last, distribution was made August 1., Three 
fourths of a quart of chinch-bugs, dead and alive, from No. 56, 
were distributed, as above, along the west side in the third, fifth, 
and seventh rows, and in three alternate rows through the center 
of the field. Mr. Wells examined the field August 5, and reported 
that he could find no signs of the fungus other than a few traces 
of the original material. 
From the above it will be seen that nearly four quarts of 
chinch-bugs, thoroughly exposed to the disease, were scattered in 
corn (B), two distributions each being made on the south, east, 
and west sides, one on the north, and one through the center of 
the field, as represented by the heavy dotted lines on the plate. 
Nevertheless this fungus practically disappeared from this farm 
during July and August, and did not appear again until about the 
middle of September. The chinch-bugs, however, continually in¬ 
creased in numbers, and caused far greater loss to corn than the 
drouth in this vicinity. September 4 Mr. Johnson found a few 
traces of the original material along the south and east sides of 
the field (B). No fungus found in corn marked D, although live 
bugs were very abundant throughout the field. Nothing indicat¬ 
ing the presence of the white fungus was seen in corn marked F, 
or in any other field on this farm, except the one (B) just men¬ 
tioned. A few bugs were found in all the meadows and pastures 
adjoining corn, but all traces of the local fungus-outbreak which 
had appeared in June had now utterly disappeared. 
Nothing further of importance was noted from this neighbor¬ 
hood until September 18, at which time the following interesting 
information was received from Mr. Wells: “I have been cut¬ 
ting corn and find diseased bugs scattered over the ground, espe¬ 
cially under stalks lying on the ground. I have seen 30 or 40 
under a single ear. I have worked with this disease with your 
assistants, and know what I am talking about. There are still 
hordes of live bugs in the field.” 
The field referred to proved to be that marked B, and was care¬ 
fully examined by Mr. Johnson September 19. The corn had been 
cut and shocked, the work having been finished the previous day. 
The ground was rather damp, but not muddy except in the south-
