BULLETIN" 299, TJ. S. DEPARTMENT OP AGRICULTURE. 



The yield table may be considered as especially applicable to pure, 

 even-aged, well-stocked natural stands of white ash, as 42 of the 63 

 plots were white .ash, 28 of which were in natural stands in New 

 York and Ohio. Fourteen plots hi planted white ash stands were 

 taken in Illinois, but did not average quite as high yields as those 

 in natural stands farther east. 



Fifteen of the plots were in green ash, 14 of which were in planted 

 stands in Iowa and Illinois and 1 in a natural stand in North Carolina. 

 The average yield possibilities for well-stocked stands of green ash 

 on southern bottom lands free from water during most of the grow- 

 ing season would be considerably above that of Quality II in the 

 table, but probably below Quality I. 



Six of the plots were in planted black ash stands in Illinois, which 

 indicated higher yields than planted white ash stands in the same 

 State. These yields, however, are very much too high to be repre- 

 sentative of the best well-stocked natural black ash stands in typical 

 black ash swamps of the Lake States. 



VALUE OF STANDING ASH TIMBER. 



A good way to figure the stumpage in any particular locality is to 

 subtract from the f. o. b. mill value of the manufactured lumber the 

 cost of production plus a reasonable profit to the producer for his 

 time, labor, and capital. The total cost of producing ash lumber 

 usually varies from -$10 to $18 per thousand board feet, and on the 

 average is not over $14. Ten per cent of the f. o. b. value of the prod- 

 ucts is enough to allow for profit in figuring what future ash stump- 

 age grown under forest management will be worth. On this basis 

 Table 16 is constructed, giving for different costs of production the 

 value of standing ash timber, which when cut into lumber will sell 

 (mill run) at the prices indicated. The amount of the producer's 

 profit is also given.
