in every case given systematic study on the ground in order to ascer- 

 tain the modifications necessary to insure reproduction upon cut-over 

 lands. 



During the year the study of Sugar Pine in California, begun in 

 1901, was completed. The field work occupied a party of seven men 

 for three and a half months. Lodgepole Pine was studied in Park and 

 Granatin counties, Mont., by a party of four men for three months. 

 Commercial hardwoods Avere studied in West Virginia, North Caro- 

 lina, Tennessee, and Kentucky, occupying 31 men, organized into 

 four parties, for four months. A study made of Balsam in the Adiron- 

 dacks, because of its rapidly growing importance in supplementing 

 the dwindling supplies of wood for paper pulp, is particularly oppor- 

 tune at the present time. A comprehensive study was made of Chest- 

 nut in southern Maryland with the specific purpose of determining 

 the best management of woodlots for the production of that timber. 

 The results of the work cover determinations of the stand per acre, 

 the rate of growth of Chestnut seedlings and stump shoots, their silvi- 

 cultural characteristics, and the method of management under which 

 they may most profitably be grown. A study of Red Pine was begun 

 in northern Minnesota. The field ork, which occupied five men for 

 three and a half months, was directed chiefiy at the study of second 

 growth in order to determine accurately what happens on cut-over 

 lands under present methods of lumbering. 



Forest Measurements. 



The section of Forest Measurements computed and put into final 

 form 25,113 valuation vsurveys, 23,455 stem analyses, 7,947 measure- 

 ments of height, and 12,217 taper measurements during the past year. 

 These dala furnished information upon the present and future stand 

 and the rate of growth in diameter, height, and volume of 42 species 

 of trees in 14 States. In addition to the computation of data and the 

 prex)aration of tables for working plans and commercial tree studies, 

 a large number of miscellaneous results obtained In other lines of the 

 Bureau's work were put into final form. It is noteworthy that during 

 the past year the section of Forest Measurements has, without increase 

 in force, completed nearly twice as many results as in the fiscal year 

 1902. 



Expenditures. 



The total expenditures during the year by the office of Forest Man- 

 agement were $71,192.48, or 24.4 per cent of the total appropriation of 

 the Bureau. 



Of the $15,114.26 contributed toward working-plan studies begun 

 or continued during the year 1902-3, 112,864.82 had been expended at 

 the end of the fiscal year. 



Work for the Ensuing Year. 



public lands. 



Under the request by the Secretary of the Interior upon the Secre- 

 tary of Agriculture, the study of technical problems involved in the 

 management of the National forest reserves and Indian reservations 

 will be taken up as rapidly as the resources of the Bureau and other 

 claims upon it will permit.
