EXPERIMENT STATION REPORTS. 161 



of the state in eompauy with Ur. A. D. Hopkius, chief of the division 

 of forest insects of the bureau of entomology. On the trip many points 

 in the life history, previously in doubt, were settled besides bringing 

 to light much loss of timber from other insect attacks. 



Two projects borne by the Adams fund of the station are now under 

 way, viz. : A study of insect diseases, or more exactly, a study of fungi 

 Avhich causes diseases among insects, preferably epidemic diseases. 

 The immediate reason for this was an attempt to control forest pests 

 by such diseases since sprays are not practical under forest conditions. 

 A number of such fungi obtained from the dead bodies of insect victims 

 have been studied and their life-history followed from germination to 

 fructification and two, found on tamarack saw-flies, one in America 

 and one in England, have been grown in quantity in order to make 

 an attempt to scatter the disease widely this summer through the 

 infested region. 



Another project soon to be under way is a careful study of the man- 

 ner in which insecticides kill insects. This will require very careful 

 investigation extending over a period of years and to carry on this 

 work, Dr. G. E. Shaffer of Cornell University has been engaged. 



The Insectary, a greenhouse which was so kindly added to our equip- 

 ment last fall, has proven perfectly satisfactory in every respect. A 

 number of species of insects have already been bred and during the 

 present season the number will be limited only by the time at our 

 disposal. 



Mr. Z. P. Metcalf has been a very able assistant during the past 

 year. He came in September and left about the middle of June, hav- 

 ing secured a much better paid position in another state. Mr. Yothers, 

 of Idaho Agricultural College, has been engaged to fill the place. 



Kespectfully submitted,

REPORT OF THE VETERINARIAN. 



Professor R. S. Shaw, Campus, M. A. C. : 



Dear Sir: — I have the honor to report as follows: As consulting 

 veterinarian of the Experiment Station, I have made one trip to West- 

 wood during the period in which Mr. Potts was in charge of the feed- 

 ing experiments at that place. I have conducted fifteen postmortems 

 upon animals submitted to the Experiment Station or to me as veteri- 

 narian, for analysis, and have examined twenty -two samples of tissue, 

 forage, stock foods, etc., likewise submitted for information. 



The correspondence of my portion of the station work has been fairly 

 heavy, at times extremely so, and I hope that it may be more satisfac- 

 torily handled and recorded by stenographic assistance during the en- 

 suing year. 



I am unable to report the jn-esence of any grave outbreaks of disease
