BULLETIN" 299, XJ. S. DEPARTMENT OF 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 in 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.
