52 PROBLEMS IN WILD LIFE CONSERVATION 



Consequently, one can only reach the conclusion that there 

 must continue to be a division of responsibility between the 

 Federal and state governments. However, when one goes 

 a step further, and attempts to define the sphere of each, he 

 is faced with an extremely difficult matter. Even the 

 familiar administrative canon dividing regulatory and pro- 

 motional functions cannot be strictly followed as a line of 

 demarcation between the Federal government and the states 

 in conservation activities. The work of the Federal gov- 

 ernment should be chiefly promotional, but it must enter the 

 field of regulation to protect the states against shipment of 

 game in interstate commerce contrary to state law. It must 

 also enter the regulatory field to fix minimum standards in 

 relation to migratory game and especially game birds. 



On the other hand, though the state must bear the chief 

 burden of the regulatory work, it should supplement the 

 promotional work of the Federal government by building 

 fish hatcheries, establishing game preserves, and educating 

 public opinion to the value of wild life. In all these enter- 

 prises the Federal government should continue, as it does at 

 the present time, to supply stimulation and advice.
