RESEARCH AND INVESTIGATION. 



Department of Agriculture. 



In. addition to the performance of their current duties, the various 

 Divisions of the Department of Agriculture are largely engaged in 

 original research and investigation. The subjects of these may be 

 roughly classified into five groups as follows : — 



(a) Diseases of animals. 



(6) Diseases of plants. 



(c) Insect pests. 



(d) Improvements of crops. 



(e) Utilization of various natural and other resources. 



In addition to the above, a botanical survey of the Union is 

 being carried on under the Chief, Division of Botany, and a con- 

 sultive committee. 



The activities of the various Divisions are as shown hereunder. 



(a) DISEASES OF ANIMALS.
