It must be borne in mind that not a single diseased insect was 
artificially introduced into this field at any time during the season, 
and that no traces of the fungus were found by Mr. Johnson at 
# the time of his former visit, September 4. It seems quite possi¬ 
ble, therefore, that the spores of this fungus were quite as abun¬ 
dant in F as in B, and that the parasite developed spontaneously 
in both fields when conditions fostered the growth of the germ. 
All other corn fields within a radius of three quarters of a mile 
were examined, but nothing was seen indicating the presence of the 
fungus. All the corn seen was badly damaged, and chinch-bugs 
were still very numerous. 
Mr. Johnson examined the fields in this neighborhood again 
September 28. The afternoon was very warm and calm, and the 
air was full of chinch-bugs flying in all directions. Mr. Wells 
said that they had been flying in great hordes the preceding day. 
The fungus was no more abundant in the corn stubble (B) in the 
open field than at the time of his former visit, but the attack 
had increased in the shocks. Fifty-one chinch-bugs dead with 
muscardine were taken from a surface area of one square foot 
under a shock near the center of the field where the bugs were 
still concentrated. Only a few were seen in the stubble. Grass 
along the lane and in the orchard between B and C was alive 
with bugs, but no dead were seen among them. The four-acre 
meadow between B and F was damaged to a slight degree, and 
all the meadows and pasture lands in the immediate vicinity of 
corn were more or less injured. 
Several fungus-covered bugs were found half a mile east of the 
Wells farm, along a dead furrow, in a field of corn where the 
ground was quite damp and the corn considerably lodged. No 
Sporotrichum had been found in this field September 18. Evi¬ 
dence of the chinch-bug muscardine was also quite common in 
low, damp places in an adjacent field of corn. Five or six whit¬ 
ened bodies could commonly be seen under every fallen stalk. 
About the same condition existed in corn one third of a mile 
south of the latter field. Tne fungus was quite common in a 
five acre corn field west and north of C, on the opposite side of 
the road, belonging to Mr. Thomas Aringt *n. It was easy to find 
a dozen or more dead bugs covered with Sporotrichum under al¬ 
most any piece of fallen herbage, or under pumpkin yfues, 
which were common throughout the field. About two and a half 
acres of the corn had been completely destroyed by chinch-bugs 
coming from wheat on the south side, leaving only an occasional 
stalk standing here and there. An hemipterous insect ( Nobis 
fusca) imbedded in this fungus, was found on the ground under 
a cluster of grass by the roadside opposite the northwest corner 
of C. 
The disease was also found in a twelve-acre field belonging to 
Mr. A. C. Rogers, one half mile west of the Wells farm. About 
half the corn in the field had been cut, the greater part of the 
remainder being flat on the ground. The stalks were dwarfed, 
the leaves dry and brown, and the ears were little more than soft
