REPORT OF BACTERIOLOGIST. 



Dean V.. S. Shaw: 



Dear Sir — Projects under investigation in this laboratory have not 

 changed materially during the past year. The personnel of the lab- 

 oratory staff, however, has undergone change and its incompleteness has 

 been reflected in the lack of progress in one of our projects a condition 

 which bids fair to be remedied in the immediate future. We are carry- 

 ing on research under five projects supported by the Adams fund as fol- 

 lows : 



la. The effect of diseases in the cow on the milk. 



lb. The keeping qualities of butter. 



2c. Soil solution and its role in the life of soil microbes. 



3a. Swine epidemics. 



3b. Bovine infectious abortion. 



It is proper to state that in addition to the strictly original investiga- 

 tions of a more purely scientific nature in connection with the problems 

 outlined above there are given consideration under the respective head- 

 ings various subsidiary and related phases of a more immediately prac- 

 tical or applicable nature. These side lights on the main Adams fund 

 projects are supported by the Hatch and State funds allotted to this 

 department as is also certain unrelated experimental work as outlined 

 below : 



1. Animal diseases. 



a. Chicken diseases, with special reference to white diarrhea 



and roup. 



b. Occasional diseases that come to our notice. 



2. Nodule-forming bacteria. 



3. Various fermentations. 



a. Vinegar. 



b. Pickles. 



c. Milk. 



d. Stock foods, grains, silage, etc. 



4. Dairy sanitation. 



5. Rural water supplies. 



Tbe investigations supported by Hatch and State funds are con- 

 ducted by the men having charge of the various Adams fund projects, 

 except that ]\nss L. Z. Northruj), Assistant Bacteriologist, and Mr. W. 

 L. Kulp, Instructor in Bacteriology have frequently responded to calls 

 for assistance in ccjnneefion with the unrelated examinations that are 

 demanded of us. 



Mr. L. H. Cooledge has continued in charge of Adams projects la and 

 all related problems and investigations. I cannot speak too highly of 

 his ability and versatility, of his industry and reliability. I have to ad-
