EXPERIMENT STATION REPORTS 117 



RErORT OF THE BACTERIOLOGIST AND HYGIENIST. 



Director C. D. Smith: 



Dear Sir — At the close of last year, I published in three bulletins 

 all the experimental data which had accumulated to that date, pre- 

 paratory to undertaking the investigation of a special milk problem. 

 I have been exclusively concerned with this during the past year. 

 It is not thought advisable to make public any of the evidence obtained 

 because of its incompleted condition and also because of the possibility 

 of misconstruction. Therefore I have no bulletin or report to issue 

 other than this respecting my investigations. 



Mr. S. F. Edwards has been engaged on some work which will be of 

 interest when completed. This work he has been doing in conjunction 

 with his other duties. 



Besides the investigations which are in progress, many specimens 

 have been received for determination and analysis. In this work much 

 time has been consumed, but we trust profitably for those interested. 

 Mr. Edwards has frequently and effectively assisted in these analyses. 



Very respectfully submitted, 



CHARLES E. MARSHALL.

REPORT OF THE CONSULTING ENTOMOLOGIST. 



Prof. C. D. Hmith, Director: 



Dear Sir — Following is a brief account of the work done by the 

 Entomological Department of the Experiment station, during the year 

 ending June 30, 1001. 



During the year part of one bulloliii (No. 180) was issued by this 

 office. The correspondence has steadily increased, until, at the present 

 time, it demands considerable time. A number of trips have been 

 maae to investigate questions bearing on the work of injurious insects. 

 A trip was made to Pontiac, and one to Highland, for the ])urpose of 

 demonstrating methods of fighting grasshoppers. At Highland, very 

 thorough search was made for the eggs of grasshoppers, with the in- 

 tention of finding out just where they were deposited; it was intended 

 to recommend fall ])lowing in such i>laces, but as vcm-v few eggs were 

 really found, that i)lan had to be abandoned. Two trips were made to 

 test the efficiency of a new remedy for the peach-borer and allied pests, 

 one to Esther and one to South Haven.
