 estry and, its bearing upon public and private welfare which has ever 

 been made in the United States. 



WORK OF THE ENSUING YEAR. 



The experiments in methods of turpentining already outlined will 

 be continued on the lands of the Hilman-Sutherland Land Com- 

 pany, in Florida. The study of basket willows will also be continued, 

 with special leference to the effects of different kinds of soil and of 

 its moisture content lyDon the quality and quantity of rods produced, 

 and to the behavior of newly imported European willows under the 

 influence of strange soils and acclimation. In the studies of special 

 groups and species of trees the Monterey pine and cypress will be 

 added to the list of little-known desert pines of California already 

 under investigation, the promised study of Gascara sagrada will be 

 begun, and the brown-wooded junipers of Texas will be taken up. The 

 study of certain kinds of acacias and eucalypts will be continued. 

 In the regional studies of North American trees the preparation of 

 Part I, Trees of the Pacific States, will be pressed forward, and that 

 of Part II, Trees of the Rocky Mountain States, will be begun. 



EXPENDITURES. 



The total expenditures for the year under the head of Dendrology 

 were $15,086.44, or 3.5 per cent of the total appropriation for the 

 Forest Service. 



FOREST PRODUCTS. 



During the present fiscal year it became plain that a complete re- 

 organization of the lines of work comprised under the head of 

 forest products was needed. In consequence of the rapid expan- 

 sion of this work, the aggressiveness with which problems of great 

 magnitude had been attacked, the multiplication of stations, the ex- 

 tension of field work, and the failure of the office organization to 

 keep pace with it, the need for better control and a firmer coordina- 

 tion of parts became imperative. To accomplish this work Mr. Wil- 

 liam L. Hall, previously the Chief of the Office of Forest Extension, 

 was put in charge. 



The investigations in progress at the beginning of the year were 

 chiefly of two kinds — studies of wood preservation and tests of the 

 strength of timbers. The wood preservation studies were grouped 

 into three sections — Eastern, Central, and Western — ^with a central 

 office in St. Louis, from which they are directed. The timber-test 

 work was conducted at Lafayette, Ind. ; New Haven, Conn. ; Berkeley, 

 Cal., and Washington, D. C., and was directed from the laboratory 

 at Lafayette, Ind. A section of dendro-chemistry was also main- 

 tained, with headquarters at St. Louis, chiefly to assist and supple- 

 ment the work in wood preservation. 



On January 1, 1905, the reorganization of the office began. The 

 system of handling cooperative fimds was changed entirely. Ac- 

 counts were submitted for all such funds expended during the first 

 half of the fiscal year, and all Iwlances in the hands of the field men
