facilities has broadened market conditions and removed depend- 

 ence on local supplies of material. The importation of tanning 

 materials has made the production of tanbark in managed forests 

 unprofitable. 



To secure a reasonable income from these areas which are 

 under coppice a change to high forest is necessary. Such a 

 change will preclude the use of the ground for grain every fifteen 

 or twenty years — a fact which complicates and retards the change. 

 This complication has been removed by making the change to 

 high forest on but half of the area, continuing and improving the 

 present practice of coppice growth on the other half.

The history of a communal forest of about 



Production 250 acres, located in the Black Forest, 



of of Wiirttemberg, near Rippoldsau, exhibits 



Selection conditions such as may be repeated in our 



Forest. country. 



In the forties, the whole forest was thor- 

 oughly logged, so that only polewood and smaller trees with a 

 few trees of advance growth had been left — such condition as our 

 loggers would leave the woods. In the fifties a wealthy man 

 bought the forest and treated it conservatively ; yet, during the 

 25 years while in his possession he cut annually at the rate of 

 75 cubic feet per acre in the average. After his death the forest 

 was offered for sale, and various valuations were made which 

 showed stock varying between 3,cxx) and 3,575 cubic feet per 

 acre. In 1879 the sale was effected for $36,000 or $144 per 

 acre, of which $30 may be figured for soil value, and $114 for 

 wood value. 



In 1899 the whole stand was calipered and showed 7736 cubic 

 feet per acre, while during the period 1072 feet per acre had been 

 cut; hence the total production during the 21 years had been at 

 the rate of 250 cubic feet. 



Since according to prices prevailing in 1900 (when this calcu- 

 lation was made), the value of the stand was close to $700, its 

 value increment per cent, for the 21 years was 8.8!
