18 THE NATIONAL FOREST MANUAL. 



Correspondence. 



(4) Correspondence of a supervisory character related to projects 

 will be filed by project number. Correspondence containing impor- 

 tant data not related to a particular project will be filed under Study 

 numbers. Other correspondence will be filed alphabetically. 



FILING SCHEMES. 



Filing schemes conforming with the foregoing classification and 

 with the general rules prescribed by the Forester will be employed 

 by the executive officer in charge of each unit of the Branch. The 

 files of Industrial Investigations will include correspondence on all 

 matters handled by the assistant forester in charge of the Branch 

 except special records of a confidential character, which will be kept 

 in his own office. 



MATTERS OF GENERAL ROUTINE. 



The instructions contained in the Manual of General Administra- 

 tion and Protection on matters of general routine, not covered speci- 

 fically in this Manual, will govern members and units of the Branch 

 of Forest Products. 



COOPERATION WITH COMPANIES, ORGANIZATIONS AND INDI- 

 VIDUALS OUTSIDE OF THE FOREST SERVICE. 



POLICY. 



It is the policy of the Forest Service to secure to as large an extent 

 as practicable the cooperation of the wood-using industries most 

 directly concerned with the subjects or problems under investigation. 

 The desirability of cooperation and its exact terms will be determined 

 in each specific case, in accordance with the following general policy 

 and procedure: 



POLICY IN COOPERATION. 

 COMMERCIAL APPLICATION AND DEMONSTRATION OF EXPERIMENTAL DATA. 



Check on commercial scale necessary. 



As a general rule, no investigation conducted by the Branch of 

 Products will be regarded as complete until the results obtained ex- 

 perimentally have been checked on a commercial scale and their in- 

 dustrial application determined. This will ordinarily be accom- 

 plished through cooperation with individuals or companies using 

 wood and who are commercially interested in the possibilities of the 

 processes or articles in question. 



Repeated cooperation covering same ground inadvisable. 



After experimental results have been satisfactorily checked on a 

 commercial scale and their applicability to wood-using industries 

 demonstrated, further cooperation covering the same ground will not 

 be entered into. This course is essential to restrict the activities of 

 the Branch to the determination of improved methods of using wood 

 and to avoid the danger of becoming consulting experts for private 

 interests.
