34 YELLOW POPLAR IN TENNESSEE. 



is taken which offers less profit, because it is declining in value and inter- 

 fering with the growth of valuable young timber. The action in both 

 cases looks toward the resultant form of forest and the profit accrues to 

 the date of future cuttings. It is as desirable that a definite form of for- 

 est be developed in the management of small tracts of from 50 to 100 

 acres as in the case of large tracts of 10,000 or more acres. While it is 

 often impossible on a large tract, on account of increasing logging costs, 

 to cut for tne best future interests of the forest, there are no such re- 

 strictions in the case of small tracts on farm. The farmer can generally 

 use his own teams and can log carefully, cutting a portion of this tract 

 each year. In this way, he is in a position in a few decades to obtain a 

 form of forest which will produce more profitably a much higher yield 

 than is possible in the case of large and inaccessible tracts. The tendency 

 of yellow poplar to occur in groups in second growth stands is shown.
