TWENTY-FIFTH ANNUAL REPORT 57 



Another project is on foot to raise the level of Yellowstone 

 Lake, which will flood the upper reaches of the Yellowstone 

 River. Similar attacks are being made on Roosevelt Park in the 

 West. These attacks on National Parks are based upon the un- 

 fortunate precedent established by the Government in sacrificing 

 the Hetch-Hetchy Valley to commercial exploitation for the bene- 

 fit of San Francisco, 



The forces of conservation are thoroughly aroused to the 

 danger, but funds will be required to meet these continuous 

 assaults and the New York Zoological Society should assist in 

 every way possible. One of the Managers of our Society, Dr. 

 George Bird Grinnell, is actively engaged in this work. 



BRONX PARKWAY COMMISSION. 



Work on the Bronx Parkway has made great headway dur- 

 ing the year. The section immediately north of Bronx Park has 

 been transformed from a collection of rock piles and tenements 

 into what will be one of the most beautiful parks in the city. 



Members of the Society are urged to view the very interest- 

 ing operation of the dredges and steam shovels before old con- 

 ditions are obliterated beyond recognition.
