36 THE WHITE-FUNGUS DISEASE IN KANSAS. 
places. Both living and dead seemed to be rather more numerous in 
the noninfected plot, but the results were indecisive. | 
Fungus was sprinkled on the bean plot in the Kellenberger oats 
field May 7, May 14, May 26, and June 4. Bugs did not become 
plentiful in this field and very few young ones appeared. There 
were a few more, both living and diseased, in and about the infected 
plot than elsewhere. .But wherever there were living bugs, diseased 
ones could be found by a little searching. 
In the Evans field the bean plots were located just north of a 
hedge and about 40 rods apart. The east plot was infected on the 
above-mentioned dates. Bugs continued very numerous all spring 
in this field. Hordes of young ones appeared about the middle of 
May and their influence, added to that of an early spring drought, 
killed much of the wheat before it was ripe. Fungus developed all 
over the field so freely that by the middle of June from 50 to 100 
dead and whitened bugs could frequently be found around the bases 
and on the roots of a single hill. While the fungus appeared in all 
parts of the field it was in general more abundant at the west end, 
so it chanced that the uninfected bean plot showed decidedly more 
fungus than the infected one. 
The “ east” straw plot was infected on the same dates as the bean 
plot and the “ west” plot was left as a check. On neither one were 
the bugs as numerous as along the side of the field on which the 
beans were planted, but both living and dead bugs were to be seen in 
about equal numbers in the infected plot and the check plot. 
The piles of straw and those of weeds were likewise infected, but 
without any appreciable increase in the death rate of the bugs. 
Although the beans had made a very good shade before harvest 
time, the bugs showed no marked tendency to seek the shade. They 
are more active on sunny days than in cool, cloudy weather, and 
when crawling from hill to hill they appear to seek sunshine rather 
than shade. 
After the wheat had ripened the bugs crawled up the bean bushes 
in considerable numbers, and many dead fungus-covered bugs could 
be seen adhering to the leaves of the plants and to the young beans. 
Famine had evidently aided the plague in this case. But here again 
there was no difference in favor of infected portions. 
To determine the efficiency of the distribution of dead bugs in 
fields I selected an oats field on the Evans farm, one-fourth of a 
mile from the experimental wheat field. A strip of about 3 by 10 
yards was sprinkled on May 25, May 28, and June 4 with diseased 
bugs grown in culture boxes. Developments on this portion were in 
no way different from those on the remainder of the field. 
On April 20 a pint fruit jar was scalded and half filled with bugs 
and soil from the Evans wheat field. Sporotrichum developed in
