United States National Forests 81 



forest affects the flow and volume of neighboring 

 rivers. 



Seven states have already taken advantage 

 of the Weeks law and set aside part of their wood- 

 land to be national property and forest forever. 



Some of these forests are in the White Moun- 

 tains, and some are in Virginia, Georgia, and the 

 Carolinas. 



The rivers which they nurture into power give 

 life to the logging industry of the eastern coast 

 states, carry seaward the waste of many factories, 

 and keep the water deep in sea harbors, where 

 ocean-going vessels make their ports and receive 

 or discharge their cargoes. 



If these rivers should dwindle, and their har- 

 bors should " shoal up," serious inconvenience 

 and heavy loss would result in all the Atlantic 

 seaport cities.
