My work shows that two treatments with this preparation per week 
almost entirely relieve the cattle from annoyance. I make the applica- 
tion with a knapsack pump fitted with a cyclone nozzle. The work is 
most conveniently done just after milking in the morning. Two men 
treat the cows rapidly, requiring about one minute per cow, and using 
from one to two pints of liquid. The preparation as given above causes 
no particularly unpleasant odor, and thus far the milkers have made no 
complaint whatever concerning its use on the cows.

THE CHINCH BUG DISEASE AND OTHER NOTES. 
By F. H. Snow, Lawrence, Kans. 
In response to your circular letter asking for notes of work done in 
economic entomology during the past year I beg to submit the follow- 
ing brief and incomplete account of the work done in Kansas this 
year under my direction in the matter of the artificial dissemination of 
a contagious disease or diseases among chinch bugs: 
The legislature of the State of Kansas at its last session in the winter 
of 1890-91 made an appropriation of $3,500, available during the years
