During the year the section of forest measurements worked up the 

 figures and prepared the tables for the working plans made hy the 

 division of forest management and for the studies of commercial trees 

 by the division of forest investigation. The data consisted of meas- 

 urements obtained in 13 States and upon 25 species. It included 

 survej^s of the stand of timber upon 10,678 acres and analyses of 

 10,786 trees. These were cast into final tables of present and future 

 stands and yields, of volume, and of rates of growth in diameter and 

 height for the localities and species covered. With the exception of 

 data obtained in the Black Hills Forest Reserve, which await further 

 figures before they can be completed, the force engaged upon forest 

 measurements has entirely finished the work for the field season of 

 1901, and has scaled also 10,000 acres of surveys left over from 1900.

 WORKING PLANS. 



Public lands. — The field work necessary to a working plan for the

 preliminary examinations of which will be made during the current 

 year. 



Private lands. — The study of private forest lands, in the handling 

 of which assistance has been requested under the terms of Circular 

 No. 21, will be carried on as rapidly as the appropriation and the field 

 force of the Bureau will allow. Particular attention will be given to 

 the rendering of assistance in the handling of wood lots. The field 

 work necessar^^ to a working plan for the 1,250,000-acre tract of the 

 Kirby Lumber Company in southeastern Texas will be undertaken, 

 and also for the two tracts of the E. P. Burton Lumber Company, the 

 one of -45,000 acres, the other of 6,000 acres, in South Carolina.

 recommendation is approved in working plans already jirepared or in 

 process of preparation.
