THE CREATION OF NEW TREES 
the number he thinks will produce the best 
results. At the end of twelve years each tree 
will offer a clear trunk without branches which, 
when stripped of its outer slabs and squared, 
will be at least fifteen feet long by a foot and a 
half square. This will give three hundred feet 
of clear timber, board measure, per tree. Black 
walnut lumber has been steadily disappearing 
from the market. Year by year it has as steadily 
increased in price until it has now become one 
of the rare woods, running in cost from $200 
per thousand feet, board measure, to $600 
or $700 per thousand feet for particularly fine 
pieces. 
Taking but $250 as the average price of 
black walnut lumber per thousand, certainly a 
conservative figure, at the end of the twelve- 
year period each tree is worth approximately 
‘$80. The acre yield would be $2,880. For an 
average farm of 160 acres the revenue for the 
twelve years, with no outlay save the cost of 
planting, not over twenty-five cents per tree, 
taxes upon the land, and interest upon money 
invested, would be a little over $460,000. This 
does not take into account the value of the 
branches, and the refuse slabs of the mill-saw-
