taken to determine the .annual requirements made upon the forest for tele- 

 graph, telephone, electric light, and trolley poles, cross-ties, pulpwood, cooperage 

 stock, veneer stock, tan bark, and wood used for distillation. 



Announcement of the total quantity of wood used in each industry will be 

 made public as soon as the tabulation is completed. The totals for lumber 

 Avill be shown by States. The final figures upon the lumber production of the 

 United States will be announced at the next meeting of the National Lumber 

 Manufacturers' Association at the Jamestown Exposition, May 28. On the 

 same date a preliminary bulletin summarizing the results will be placed in the 

 hands of the press. 



Reports have been obtained from a much larger number of manufacturers 

 of lumber than last year, and the statistics will be correspondingly more ac- 

 curate and complete. Immediately following the compilation will begin the 

 preparation of detailed reports for each industry. It is expected that the 

 manuscripts will all be ready for the printer by July 1, 1907. 



Map Notes 



The establishment of the new inspection districts has aroused a demand for 

 classification maps for the files of the inspectors, and six colorists have been 

 employed temporarily on the drafting force for the purpose of pushing forward 

 the work. The best base maps available at present will be used, and any which 

 are not satisfactory will be replaced later when better maps are obtainable. 



A scheme of classification has been adopted for use on boundary diagrams, 

 and in the future the plats will show what the changes made by the proclama- 

 tion consist of in addition to showing the boundary established. 



Centralization Timber-Test Computations 



The coordination of the timber-test work through the establishment of a 

 central office in Washington with complete files of data will be still further 

 carried out by having all the test results forwarded to Washington for working 

 up in the Computing Section. The scheme is for each laboratory to send- in 

 its data once or twice a week for prompt calculation. The result will be that 

 those in charge of tests will be relieved of the labor of routine calculating and 

 always have the results of their tests available to guide them in directing their 

 work. 



Wood Uses- 

 Arrangements are being completed to make a study of the tanbark oak of 

 California. The work is to be done in cooperation with some of the leading 

 lumber companies and with the Office of Silvics. The purposes of the study will 

 be to obtain an estimate of the stand and to determine the best methods of 

 handling the timber and the uses for which it is most suitable. 



At present a considerable quantity of this timber is cut for bark. The trees 

 are stripped and the wood is often left in the forest to decay.
