YIELD TABLES. 



Dense, even-aged stands of forest trees of different ages have been 

 accurately measured for a number of species and the resulting 

 yields tabulated. These tables show yields exceeding those of 

 average wild forests, but show what is possible when the forest is 

 properly handled. They represent the beginning of American 

 yield tables, which will be of the greatest value as a guide in forest 

 management in the selection of species or in estimating the returns 

 from planting.
