office for execution by the lessoz^_ Supervisors 

 must, never occupy an office that is furnished rent free by a 

 company or individual. 



FOREST LIBRARY. 



To aid in the work of Forest officers, supervisors' offices are 

 being provided with small libraries of books on forestry and 

 allied subjects. In addition, all available Government publica- 

 tions of interest will be sent to any member of the Forest 

 Service free of charge, on application to the Forester. 



In order that rangers may be made more familiar with the 

 books- in the field libraries, each supervisor is instructed to 

 send in succession all the books in his library to each ranger, 

 for his inspection or perusal. 



Before starting a book on its rounds, the names of all the 

 rangers who are to use it should be entered on the charge card 

 found in the pocket on the inside of the back cover. The book 

 su^uld then be sent to the ranger whose name comes first on 

 tlie card, to be returned to the supervisor's office when he is 

 through with it. The card should be kept on file by the super- 

 visor, in order that he may know where the book is. As soon 

 as the book is returned by the first borrower, it should be 

 sent to the man whose name conies next on the list. The book 

 should be kept in circulation in this way until every ranger 

 has had a chance to see it. 



EXPENDITURES AND SUPPLIES. 



All payments for expenses incurred in the administration of 

 the National Forests must be in accordance with the acts of 

 Congress making appropriations for the purpose, the_Fiscal 

 Regulations of the Department of Agriculture, and the instruc- 

 tions in the Green Boo of the^ Forest Service. Detailed in- 

 structions for the custody and use of supplies are contained 

 in the Green Book, a copy of which should be in the hands of 

 every Forest officer.
