Measurements taken on a 20-year old stand seeded on an abandoned 

 field show the following: 



A sample acre taken in a 45-year old stand shows the relatively high 

 yield for saw-timber, veneering, and pulpwood obtained in this period.

The acre taken in the 20-year old stand has produced 23.9 cords of 

 Cottonwood and willow of a size suitable for pulpwood purposes. The 

 elm and soft maple form an unmerchantable under-story. This pulp- 

 wood has a stumpage value of $1.25 per cord, or $29.88 per acre. The 

 land was originally purchased for the shooting privileges. Taxes at forty 

 cents p>er acre per year compounded for 20 years at 5 per cent total $13.23 

 per acre. This acre, if harvested at twenty years as pulpwood, will pay 

 the carrying charges of taxes with interest on taxes ; and will show a net 

 return of $16.65 or $ .83 per acre per year from land unsuitable for agri- 

 culture. 



The sample taken in the 45-year old stand shows a production of 

 58.1 cords of cottonwood, soft maple, and elm suitable for pulpwood, or 

 16,600 B. F. of material suitable for veneer logs. Devoted to pulpwood, 

 the stumpage value for 58.1 cords at $1.25 per cord is $72.62. Taxes, 

 at $ .40 per acre, compotmded over 45 years at 5 per cent total $55.88. 

 Thus, this acre, if harvested for pulpwood at 45 years, returns $16.74 

 over the carrying charge of taxes with interest on taxes ; or $ .37 per 

 acre per year. 



Devoted to veneer or sawlogs, the 45-year old plot shows a yield of 

 16,600 B. F. per acre of this material. A stumpage value of $10.00 per 

 M. gives the value of this acre for veneer material as $166.00, annual 

 taxes at $ .40 per acre compounded at 5 per cent total $55.88. Thus, this 

 acre, if harvested for veneer logs, returns $110.13 over carrying charges 

 of taxes and interest on taxes, or $2.67 per year.
