44a EXPERIMENT STATION. [Jan. 



ANALYTICAL AND DIAGNOSTIC SERVICE. 



From the founding of the Experiment Station, work of this 

 character has formed a large part of the service rendered to the 

 people of the State. The work as now organized is carried on 

 in the following departments: — 



1. Department of Plant and iVnimal Chemistry, which has charge of the 



chemical anahlical work. 



2. Department of Botany, which performs certain analytical work with 



reference, to seeds, and likewise a large amount of diagnostic work 

 with reference to plant diseases. 



3. Department of Entomology, which is subject to numerous calls on 



the diagnosis of insect troubles. 



4. Department of Veterinary Science, which performs similar service 



with reference to animal diseases, and particularly poultry diseases. 



A part of this work has definite investigational value. It is 

 through the information gained in the diagnostic work that the 

 Departments of Botany, Entomology and Veterinary Science 

 are able to keep in touch with conditions all over the State. 

 It must be remembered that the Experiment Station is expected 

 to give State-wide service, but despite this it has no field 

 organization. On the other hand, certain phases of the work 

 are to a certain degree of commercial or personal service 

 nature. This work is being discouraged. Since, however, cost- 

 free service of this kind has been offered by the station for the 

 past forty years, it is not possible to do away with this in any 

 short period of time. The correspondence connected with the 

 carrying on of this service is heavy, and is of a definite ex- 

 tension nature. It is probable that some of this work should 

 be organized under the Extension Service rather than under 

 the Experiment Station.
