Interest of Women in Conservation 



THE following communication from 

 Mrs. Frances Shuttleworth, cor- 

 responding secretary of the Wom- 

 en's National Rivers and Harbors Con- 

 gress, is another indication of the in- 

 tense interest that is taken by women 

 generally, and clubwomen in particular, 

 in the conservation movement : 



]{ditor Coxservation : 



I am writing to congratulate you on 

 the splendid magazine you are now pub- 

 lishing in the interests of our natural 

 resources. Particularly am I interested 

 in all articles that touch on waterways 

 and forests. As you may know, the 

 \\"omen's National Rivers and Harbors 

 Congress was 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
