548 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



of assistance to the Forest Service and to private timberland owners 

 in the disposal of certain species of trees not in demand for himber. 



AVestorn red cedar supplies the material for (55 per cent of the 

 shingles produced in the United States. The manufacture of such 

 shingles is confined almost entirely to the State of Washington, where 

 it forms a very important industry. A study of this industry, begun 

 in 1011, was completed during this year. 



Another study dealt with the industries which use the products 

 of wood distillation, especial attention being given to the proportion 

 of the products used by each. 



The cooperative work between the Forest Service and the Bureau 

 of the Census in collecting and compiling statistics of forest prod- 

 ucts of the United States was continued during the year. The sta- 

 tistics gathered annually now cover lumber, lath, shingles, crossties, 

 pulp wood, slack and tight cooperage, veneer, poles, cross arms, 

 brackets, insulator pins, excelsior, and wood distillation, while fig- 

 ures for consumption of tanbark and tanning extract, turpentine and 

 rosin, and mine timbers are secured every five years. In addition, 

 statistics relating to wood preservation are gathered annually by the 

 Forest Service. 



AATiolesale lumber prices, f. o. b. market and f. o. b. mill, were 

 collected and issued quarterly, as in the previous year. These fur- 

 nish a continuous and permanent record of the rise and fall of lumber 

 values. 



Wood-using industry studies, which show the kinds and amount of 

 wood required by the various industries, the purposes for which the 

 different species are employed, and the extent of their use, were com- 

 pleted in Alabama, Arkansas, California, Illinois, Louisiana, Michi- 

 gan, Mississippi, Missouri, Tennessee, Texas, and Washington. Field 

 work was completed for similar studies in Connecticut, Florida, 

 Georgia, Idaho, Iowa, Kansas, Maine, Minnesota, Montana, Nebraska, 

 New Hampshire, North Dakota, Oklahoma, Rhode Island, South 

 Dakota, Vermont, and Virginia. When all States have been cov- 

 ered it is planned to issue the results in two series of publications — • 

 one to give the uses to which the important commercial woods of the 

 United States are put, the other to discuss the requirements and 

 the methods of manufacture employed by the wood-using industries. 



MISCELLANEOUS. 



During the year the Forest Service issued 44 new publications as 

 against 31 the year before. Revisions of three older publications 

 were also issued. The total number of Forest Service publications 

 distributed was 359,129 as compared with 245,500 in the previous 

 year. Most of the bulletins and circulars were of a technical charac- 

 ter, presenting the results of investigative work. Besides the publica- 

 tions issued there yvere 17 new bulletins and circulars in press at the 

 end of the year. 



One thousand and fifty-four books and pamphlets, most of them 

 free publications received either directly by the Forest Service or 

 through the library of the department, were added to the library of 

 the Washington office, bringing the total number of volumes there up 

 to 16,017. Sixty forest and trade journals, about half of which are 

 secured free and half purchased by the department, are regularly 

 received at Washington.
