UTILIZATION, MARKET AND TECHNOLOGY. 



The thrift of a growing stand is always in- 



Use creased by proper thinning, but in many 



of localities in Germany the material so re- 



Thinning moved can not be sold at a price sufficient to 



Material. cover the cost of handling. There is urgent 



need for some method of utilizing this small 



material. The production of charcoal appears to offer a solution 



of the problem in some localities and such use is being actively 



promoted by the "Forstbiiro Silva" in Darmstadt. The present 



paper gives some of the general features of charcoal production in 



meiler kilns in the Thiirgingerwald and outlines the author's 



efforts to introduce a similar practice in the Vogelsberg. Other 



possible uses for small material from thinning are indicated.

Ten large manufacturers of southern yellow 

 Cost pine timber contributed detailed cost figures 



of Producing which include costs from the woods thru the 

 Yellow Pine saw mill and planing mill, to the buyer. The 

 Lumber. total costs, omitting stumpage, are peculiarly 



uniform when the fact is taken into con- 

 sideration that the methods of cost-keeping are different, and that 

 the logging and milling operations are carried on under widely 

 varying conditions. Stumpage varies from $1.90 to $5.00 and is 

 not included in the following table of costs. 



Total cost per M., actual averages from large manufacturers: 

 $12.83; $11-57; $10.68; $10.67; $10.37; $10.03; $9.84; $9-49; 

 $9.06 ; $8.49. 



The analyses of most of these costs are very detailed but the 

 items vary so much that a general comparative summary would be 

 impossible. In a few tables contracts and company work is com- 

 pared. The table following was compiled by "The Lumberman" 

 and seems to give reliable costs, providing all of the timber cut 

 was put through the planing mill.
