Fifth Annual Report. Ay 
the moisture in the bottom, but not in small corn; not enough 
to be practical. What might be done in wetter weather, I am 
not able to say. The water-colored greenish fungus mentioned 
in report of 17th is more numerous to-day, and more vigorous, 
not, however, in very great quantity. 
From this time on my observations were not confined to this 
field. About the Ist of July a little rain fell, and reports came 
in that the bugs were dying in the corn-fields very rapidly. On 
the 4th of July a heavy rain fell, and wet weather followed. 
From the 1st to the 15th the bugs were killed by the fungus on 
nearly every field where they were so far as I could learn. [I 
concluded that there was another cause at work to render the 
fungus more effective than that of rainy weather, from the fact 
that from the Ist to the 4th there was but little more moisture 
than during the days immediately preceding, and not so much 
as during the early part of June. Yet reports came in that the 
bugs were dying rapidly in the corn-fields before the rains of 
the 4th and the days following. 
VITI.— CONSIDERATION REGARDING STATUS OF SPORO- 
TRICHUM. 
We have said that the conditions upon which the spread of 
Sporotrichum among chinch-bugs depends are complex and not 
entirely understood. We will here offer certain considerations 
regarding the status of Sporotrichum which may be suggestive 
to those interested in the work of the Station of the difficulty 
of reaching positive conclusions without data ranging over a 
long series of years and embracing a wide range of meteoro- 
logical conditions. 
A.—That Sporotrichum generally throughout the state survived 
the winter of 1894-95 is indicated by the following: 
1. It was found in 1895, early in the spring and at different 
times during the year, in many fields where no Sporotrichum 
had been artificially introduced in 1895. It was present in a 
great majority of fields examined where bugs were abundant, 
and was found in different parts of the state. 
2. Chinch-bugs sent to this Station from many different lo-
