ADMINISTRATION OF SALES GENERAL. 



The chief objects of timber-sale administration are to obtain the 

 best forest conditions possible and complete utilization, with a mini- 

 mum cost to the Service and prompt attention to the purchaser's 

 needs. 



Actual participation where possible and at least frequent per- 

 sonal supervision by supervisors, deputy supervisors, and Forest 

 assistants of all woods work is essential, as is also close supervision 

 by the officer in charge in order that the purchaser may know from 

 the first exactly what will be required of him and that his expenses 

 may not be increased by delayed changes in method. 



Small sales are as important from a silvicultural standpoint as 

 larger ones, consequently the methods used in each
