BUREAU OF F0KE8TRY. 511 



PRIVATE LANDS. 



The field work necessary to a working plan for the tract of the 

 Houston Oil Company in southeastern Texas will be continued. 

 Under the conditions of Circular No. 21, a working-plan study will 

 be made of the 27,000-aere tract of E. P. Burton & Co. in South 

 Carolina and of the 100,000- acre tract of the Kaul Lumber Company 

 in southern Alabama. Particular emphasis will be laid upon the 

 preparation of plans for the conservative handling of woodlots, 

 which is rapidly becoming one of the most important lines of work in 

 the Bureau. 



INSPECTION. 



The marking of the timber to be left standing upon the lands 

 which will constitute the Minnesota National Forest Reserve will be 

 continued, and the rules for lumbering, which have been prepared 

 by the Forester, will be put into effect under the direction of the 

 Bureau of Forestry. The supervision of the markings of trees to cut 

 and of conservative lumbering will continue upon those lands already 

 under the general supervision of the Bureau, or which, as the result of 

 the approval of working plans already completed or still to be pre- 

 pared, are placed under supervision during the coming year. 



STATE COOPERATIVE FOREST STUDIES. 



The forest study in California will be continued to completion, and 

 the results of the first season's work will be embodied in a progress 

 report. The study of the forests of New Hampshire will be completed 

 along the lines already established. A study will be made of impor- 

 tant forest problems in Vermont, especially of those which confront 

 the private owner. 



COMMERCIAL TREES. 



Balsam will be studied in Maine and work upon this species brought 

 to a completion. The study of Southern hardwoods will also be com- 

 pleted and the results prepared for publication. The study of Red 

 Pine in Minnesota will be continued, and during the winter a com- 

 prehensive study of White Pine in Minnesota and of the Southern 

 pines will be begun. 



FOREST MEASUREMENTS. 



The computation of field results obtained by the Bureau will con- 

 tinue. 



FOREST INVESTIGATION. 



The division of Forest Investigation has covered a very wide field 

 during the past year. Its work in turpentine orcharding has fur- 

 nished its most notable contribution to the progress of forestry. 



Turpentine Orcharding. 



One full season's te'st has been made of the cup system of turpen- 

 tining, introduced by the Bureau, in comparison with the "box" 

 method. The following very important facts have been established ; 



(1) That the box is a destructive and unnecessary wound.
