importance, but as yet little accurate information is available on the 

 subject. 



A working plan in Alabama, including a study of less wasteful 

 methods of lumbering white oak and hickory. 



Conservative management of a forest of mountain cedar is the chief 

 problem of a working plan for a tract of 20,()00 acres in Paloduro Can- 

 yon, in western Texas. Wise use of the forests of this valuable tree 

 is a matter of the greatest importance over a vast area of otherwise 

 treeless country in the Southwest. 



Two working plans, one in Washington and one in Idaho, will be 

 made for very large tracts, in one case of two million acres, and in the 

 other of over one million. The problem here is not, as is often the 

 case in the East, so much to increase the yield of the forest as it is to 

 devise modifications of logging which will prevent the total destruction 

 of the productiveness of lumbered lands. These working plans afford 

 the opportunity to make practical application of the studies of those 

 Western commercial trees which the Bureau has made as the founda- 

 tion for effective work in actual management. Continued attention 

 will be given to the preparation of working plans foi- woodlots. The 

 unique opening which this line of work affords for spreading among 

 small owners, whose holdings are so important in the aggregate, a knowl- 

 edge of how to get the most out of their woodland, gives special impor- 

 tance to these studies. 



STUDIES OF COMMERCIAL TREES. 



The purpose of the Bureau in its commercial tree work during the 

 coming year is to complete as rapidly as possible the studies of those 

 trees for which sufEcient mathematical data have been collected. This 

 will be done b}^ giving to trained men the task of making practical 

 application to specific problems of the large amount of information 

 now on hand. The studies to be thus completed during the year are 

 for yellow poplar, white, black, red, and chestnut oaks in the South, 

 sugar pine in California, lodgepole pine in Montana and Idaho, and 

 western yellow pine. 



EXPENDITURES. 



The total expenditures during the year under the head of Forest 

 Management were $42,636.67, or 12 per cent of the total appropriation 

 of the Bureau.

FORESTS IN long ISLAND COUNTIES. 



A descriptive forest study of Suffolk and Nassau counties, Long 

 Island, N. Y., was begun and completed during the year. Its object 

 was to supply information as to the desirability of a State forest 

 reserve in that region. The report will be accompanied by a type 

 forest map, and will contain the results of a thorough study of the 

 forest conditions of these counties, with special attention to the eco- 

 nomic value and importance of existing forest growth as a protection 

 to local water supply.
