NATURALIST'S GUIDE TO THE AMERICAS 



ments are needed to supplement public 

 support. The greatest progress is made 

 where public and private aid is com- 

 bined with high and practical idealism. 

 A movement should be started for en- 

 dowments for educational and scientific 

 work in both National and State Parks. 



14. Park endowments are perhaps 

 one of the best means of developing a 

 technical staff for our parks. The 

 preservation of wild life requires such 

 supervision by specialists. 



15. The wild life problem suffers 

 from the major defects of our democratic 

 system of control, and its welfare de- 

 pends fundamentally upon improve- 

 ments in this.
