Summary of Two-Day Test Work, December, 1922, through November, 1928. 



Number of Cows tested. 



13a 



Number of Herds visited. 



The total number of tests made during the year ending December 1, 1923, decreased by 1,172, compared 

 with the previous year. 



There were twenty men employed for the seven-day Holstein work, 38 farms visited, and 125 reports 

 turned in. 



DIAGNOSTIC AND ANALYTICAL SERVICE. 



In addition to the service already reported the Station performs a large 

 amount of diagnostic and analytical work. The department of Veterinary Science 

 examines samples of diseased poultry sent in for examination, makes diagnosis 

 and reports back to the sender. The department of Botany makes similar exam- 

 inations of diseased plants submitted, and the department of Entomology diag- 

 noses insect injury from such samples of either plant or insect as may be sent in. 

 This work is all of it most important. It is not duplicated by any other agency in 

 the State, and requires a very high degree of skill in its performance. It must 

 be admitted, however, that it is a hea\'3^ drain on research funds, and that the 

 same work must be repeated annually for different individuals or communities 

 over a period of many seasons. For this reason the work would be more efficient 

 if it could be organized under the Extension Ser\ace. 



In the department of Plant and Animal Chemistry, many analyses are made of 

 milks, creams, feedstuffs and other products submitted for examination. This 

 work differs from the foregoing in that more is for the benefit of the individual and 

 less for that of the State or a group of citizens within the State. For this reason a 

 fee is charged for certain parts of this work. The same department has given most 

 valuable service in co-operating with other Station departments through making 

 analyses of soils, fertilizers, feeds, plants, insecticides and fungicides and other 

 materials on which information was needed. The co-operative spirit in which this 

 work has been done is most gratifying.
