LETTER OF TRANSMITTAI, 



U. S. DEPARTMENT OF AGRICULTURE, 



FOREST SERVICE, 



'./ : I/: : : Washington, D. C., March 13, 1911. 



*SiR: 1 have., the honor to transmit herewith a manuscript entitled 

 !?tCaJffiryia.'Ta2jbark Oak/' by Willis Linn Jepson, collaborator, and 

 H. S. Betts, engineer in timber tests, together with an Appendix by 

 C. D. Mell, assistant dendrologist, and to recommend its publication 

 as Bulletin 75 of the Forest Service. This bulletin shows how the 

 complete product of tanbark oak its bark and its wood may be 

 utilized. It is important that this complete utilization should be 

 brought about. The wood is now left in the forest to rot unused or 

 to add fuel to forest fires. The timber tests show that the lumber 

 has a high value and can be put to the same uses to which the eastern 

 oaks are put. A careful handling of woodlands, coupled with con- 

 servative lumbering, ought to make the tanbark-oak crop continuous 

 and render this resource inexhaustible. 



Respectfully, . HENRY S. GRAVES, 



Forester, 

 Hon. JAMES WILSON, 



Secretary of Agriculture,
