problems, snolu for instance, as the proportion of the Avhole grain fed 

 to animals of the cattle kind that may pass throngh Ihe system unmas- 

 ticated and therefore nndigested, of the feeding of cull Ix^ans to pigs or 

 of dried beet pnlp to fattening steers. This work and the subsequent 

 bulletins eminate directly from the appropriation made by the legis- 

 lature of 1905. I am glad to recognize the generosity of the state in 

 this respect, being assured that under the wise and conservative man- 

 agement of Prof. Shaw the funds are to be so spent as to produce the 

 greatest possible good to the greatest possible numlier of Michigan 

 farmers. 



There was a very visible increment to the funds of the experiment 

 station arising froin the passage of the Adams bill. During the year 

 ending June 30, 1007, there came to the station from this source |7,000, 

 which was spent upon the following five projects. 



1. A study of the bacteriological factors influencing the keeping qual- 

 ities of milk and butter. 



2. A study of hog epidemics in Michigan. 



These two projects were carried forward by the Bacteriological De- 

 partment. 



3. A study of the action of bacteria in rendering available the in- 

 soluble elements of the soil. 



This project was carried forward by the Departments of Bacteriology 

 and Chemistry, working jointly. 



4. A study of the utilization of untreated rock phosphate. 



This project was carried forward by the Chemical Division of the 

 Experiment Station. 



n. A study of the Grand Traverse disease of cattle. 



This project was carried forward by the veterinarian and the director 

 of the Exi^eriment Station. 



By the terms of the Adams bill the expenditure of this fund is lim- 

 ited to the prosecution of investigations and research aimed to the 

 broadening of human knowledge on matters of pure science. At the 

 same time the attempt was made in the selection of the topics named, 

 to make the results of the investigations as immediately helpful as 

 possible. No reports are forthcoming as yet or will be forthcoming in 

 the immediate future in bulletin form from the ex])enditure of this 

 fund. From the very nature of the work no definite results can ha 

 expected for some years to come. 



It is pleasant to report, however, that in the matter of (he Grand 

 Traverse disease of cattle, definite and conspicuous progress has been 

 made. Mr. A. R. Potts, lor many years an employee of the station in 

 the farm department, was sent to West Olive, where the disease was 

 ]>revalent. An examination of the stomachs of the animals altlicted 

 with the disease showed the third stomach to be in every case impacted. 

 The adoption of a course of treatment aimed to relieve this condition 

 resulted in the recovery of nearly every animal treated. The investiga- 

 tion as to the cause of the disease is still in progress. 



There is attached to this report, and made part of it, the reports 

 of the heads of the different divisions of the station work. These re- 

 ports are full and hardly need comment from the director. I am glad 

 to report that harmony has prevailed in the councils of the station, 

 and that the investigations are progressing without waste of energy
