accessibility ; approximate total quantity and percentage of material 

 particularly snited for propeller stock, wing beams, or any other spe- 

 cial use; present utilization; improvements in logging or milling 

 which will increase production ; and means of utilizing new tracts. 



In general a large amount of information on the most suitable 

 woods for various purposes, together with their sources of supply, 

 availability, and commercial value, have been furnished to the War 

 and Navy Departments and to other cooperators. 



The Forest Service has also undertaken a comprehensive study of 

 the current production and distribution of lumber and a census of the 

 wood requirements needed to carry out the military program. Its 

 purpose is not only to analyze the factors which have a direct bearing 

 on lumber production and distribution, but also to formulate a con- 

 structive policy which w^ill aid the industry in meeting the demands 

 made upon it. The results will be available in the form of current 

 statistics on lumber production, shipments, • and stocks on hand, 

 supplemented by special reports on various industrial problems com- . 

 mon to the lumber industry. Data regarding the annual production 

 of lumber, lath, and shingles, the production of wood pulp and con- 

 sumption of pulpwood, the amount of timber treated with wood 

 preservatives, and the quantity of preservatives used were collected 

 as in past years ; and arrangements were made for collecting and com- 

 piling data on wood distillation, cooperage manufacture, and ply- 

 wood manufacture. A large volume of statistical data of this char- 

 acter has been furnished for the use of various Government units. 

 Figures on production and consumption in many instances have been 

 used as a basis for reaching conclusions in problems of utilization, 

 substitution, and regulation of imports and exports. 



The requirements of the war necessitate a still further enlarge- 

 ment in the research organization, for which funds are urgently 

 needed. 



MISCELLANEOUS. 



Thirty-four new publications were issued. The distribution of 

 Forest Service publications totaled 370,100 copies. About 110 ad-

 entries covering 2,652 books, periodical articles, and manuscripts. 

 Arrangements were made for abstracting the principal articles in the

 on special subjects were prepared, of which one on forest taxation
