BDEEAU OF FOEESTEY. 517 



SPECIAL STUDIES. 



Studies of swamp forests in Missouri and Arkansas will be continued 

 during this field season, and a special study will be made of the dis- 

 tribution, growth, and commercial value of swamp hardwood forests 

 in Texas. 



Monographic studies of the Black and Red oaks will be carried for- 

 ward to completion. This work will be concerned mainly with the 

 silvicultural requirements and growth of these oaks for the purpose 

 of completing unfinished reports by the late Doctor Mohr. 



The study of the distribution, reproduction, and ownership of the 

 Big Trees of California will be continued, and should be followed by 

 important recommendations for the preservation of the most unique 

 of our forests. 



A systematic study of the timber and other Acacia tree species 

 indigenous and naturalized in California, Arizona, New Mexico, and 

 Texas will be continued. 



Experiments will be continued on the Potomac Flats to determine 

 the best methods for the production of commercial Basket Willow 

 rods, the best supplies of which are at present imported largely from 

 foreign countries. 



TURPENTINE OEOHABDING. 



Field experiments will be continued at Ocilla, Ga., and elsewhere 

 to compare still more widelj' and accurately the cup system and the 

 box system, to improve the cup system further, and to increase the 

 yield. A study of the French system of turpentining is being made 

 on the ground. 



FOREST EXHIBIT. 



The Bureau's exhibit at the World's Fair, St. Louis, Mo., 1904, will 

 be installed during the present fiscal year. The detailed prepara- 

 tion is going forward as rapidly as possible. 



FOREST LIBRARY. 



The usefulness of the library will be increased during the coming 

 year by making available for reference, by title, author, and subject 

 index, all essential published matter bearing on forestry and closely 

 related subjects. Summaries of published information on special 

 subjects will be made by the library force. Material is being col- 

 lected for a general history of State forest legislation. 



FOREST PHOTOGRAPHS. 



The photographic laboratorj^ will be continued as heretofore. 



FOREST EXTENSION. 



The forest-extension work of the Bureau of Forestry has to do with 

 the creation of forests where at present there are none. It continues 

 the cooperative planting carried on by the Bureau with private land- 

 owners since 1899, and includes forest planting on the public reserves, 

 the investigation of forest fires, studies in foi'cst replacement, and the 

 reclamation of shifting sand dunes.
