EXPERIMENTS IN 1895. 
I.—GENERAL SUMMARY OF THE YEAR’S WORK. 
1.—THE CHINCH-BUG AND THE WEATHER. 
The winter and spring months of 1894 and 1895 were un- 
usually dry, and furnished excellent conditions for the hiberna- 
tion of chinch-bugs, and in consequence they have been present 
‘in Kansas in large numbers during the past two years. The 
two successive favorable periods of hibernation resulted in a 
much larger number of bugs in 1895 than in 1894. We infer 
that the periodic appearance and disappearance of chinch-bugs 
_ in a locality is largely due to favorable or unfavorable con- 
ditions for hibernation in that locality. A wet fall, winter 
and early spring are pretty certain to result disastrously to the 
bugs. If there be a succession of such periods the chinch-bugs 
practically disappear. ‘There are always some survivors, how- 
ever, and a brief succession of dry hibernation periods results 
in their rapid increase. It is probable that the disappearance 
of bugs during wet hibernation periods is due to the ravages of 
_ diseases, but of this we have as yet no certain proof. 
2.—SPOROTRICHUM AND THE WEATHER. 
The dependence of Sporotrichum upon the weather has been 
more evident this year than ever before. We have had a sea- 
son of extremes, a very unusual dry spell with clear skies dur- 
ing the three spring months, followed by heavy and frequent 
rains and cloudy skies for the three summer months. A some- 
what detailed statement of the weather conditions will be of 
service here, and since the character of 1894 probably had some 
influence on the number of bugs in 1895, the statement will 
include 1894. 
During the 12 months preceding January, 1895, the rainfall 
was 6.06 inches below the average of the preceding 26 years. 
From January 1, 1895, to June 1, the rainfall was 5.11 inches 
below the average of the same period in the preceding 27 years,
