F.1MTOK CoNSKKVATloN : 



I am writing to congratulate you on 

 the splendid magaxine you arc now pub- 

 lishing in the interests of our natural 

 resource^. Particularly am I interested 

 in all articles that touch on waterways 

 and forests. As you may know, the 

 Women's National Rivers and Harbors 

 ( ongrcss \vas organized in Shreveport, 

 La., on June 29 last, to promote as one 

 problem the development of all prac- 

 ticable waterways and the extension 

 and conservation of forests. This Con- 

 gress aims to cover the nation with a 

 net work of information that will in 

 time bring men and women to a full 

 realization of our country's possibilities
