INSURANCE. 



To secure insurance at the lowest possible rate a mutual 

 benefit association has been formed of employees of the Forest 

 Service, the Geological Survey, and the Reclamation Service. 

 This is solely to give employees health, accident, and life insur- 

 ance at cost, and to prevent unnecessary burdens falling upon 

 the associates of sick or disabled men. Information concern- 

 ing membership in this association can be obtained from the 

 supervisor. 



SPECIAL STUDIES UPON NATIONAL FORESTS. 



It is the active policy of the Forest Service to man- 

 age the National Forests upon a sound technical, as 

 well as business, basis. Improvement in the standard 

 of the technical management alone can secure steady 

 and constant increase in returns without depleting the 

 Forests. To this end careful investigation is essential. 

 This includes special study of the habits and require- 

 ments of trees as a basis for the regulation of cutting 

 of every kind. Special attention will be given to find- 

 ing new uses for species at present valueless or little 

 used, as well as for the trees already classed as com- 

 mercial. Studies will be made of damage by fire and 

 the best means of preventing it, and, in cooperation 

 with the Bureau of Entomology and the Bureau of 

 Plant Industry, of the prevention and control of insect 

 ravages and tree diseases. In these and in many other 

 ways the basis of knowledge necessary for the best 

 forest work will be laid. 



To sum up, the National Forestjv]in3e^sti]died with 

 reference to their best use__foy; even T pnnpn^p These 

 studies will not be limited to the present applications
