INSTRUCTIONS RELATING TO FOREST PRODUCTS. 9 



(8) Advice and assistance to persons in the respective districts, 

 outside of the Forest Service, on any of the foregoing or related 

 questions. 



(9) Preparation of publications on any subjects covered by the 

 foregoing investigations which have practical or scientific value. 



(10) Demonstrations of methods or processes developed by the 

 Forest Service for the benefit of local industries. 



Duties of forest supervisors. 



To make Products work in the National Forest districts of the 

 greatest value it is essential that supervisors bring to the attention 

 of the district foresters any problems bearing on the foregoing or 

 related subjects which exist on their Forests. The presence of large 

 quantities of unmarketable species, of dead timber, or of material 

 not used in current sales should be reported. Local problems in 

 manufacture and marketing like sap stain, difficulties in kiln drying, 

 market prejudices against usable material, and the effect of given 

 silvicultural methods upon the average grades of lumber manufac- 

 tured should be taken up with the Products experts at the district 

 office. Supervisors are expected to cooperate in studies along any of 

 these lines and in more general investigations, such as local supply 

 and demand for stumpage, which the district forester orders. 



Preservative treatment of material used in improvements. 



Forest supervisors should also bring to the attention of the district 

 foresters their needs for assistance in applying preservative treat- 

 ment to telephone poles, posts, and other material used in the con- 

 struction of National Forest improvements. Important projects re- 

 quiring such timbers should be discussed in advance with the Products 

 expert in order that plans for preservative treatment may be thor- 

 oughly considered and applied if found advisable. In the" discretion 

 of the district forester, small treating plants may be constructed and 

 operated on or near National Forests where of value to the Forests 

 and the community. The object of such plants will be to facilitate 

 National Forest improvements and to educate the people in the use 

 of preservatives. Recommendations for their establishment should 

 be made by supervisors when advisable in their judgment. 



INDUSTRIAL INVESTIGATIONS. 

 Purpose. 



The function of the Office of Industrial Investigations is to conduct 

 statistical and industrial studies of uses of wood in the United States. 

 The aim of these investigations is to determine the methods and 

 conditions under which wood is now used, the marketable products 

 obtained from it, tendencies in methods of manufacture, and im- 

 proved methods possible particularly in the utilization of waste. 

 When practicable such investigations will be followed by the com- 

 mercial application of their results. This unit also directs all sta- 

 tistical investigations of the production and use of forest products 

 conducted by the Forest Service and standardizes the methods em- 

 ployed.
