THE FOREST EESOURCES OP THE WORLD. 



Yield according to species. — The average yield of derbholz (wood 

 over 2| inches in diameter) is greater for conifers than for the broad- 

 leaf species. The yield of the state forests in Wurttemberg per acre 

 gives the following result :

Forests in coppice and compound coppice yield less than high 

 forests; e. g., in the state forests of Baden the yield per acre for high 

 forests from 1892 to 1896 was 79.5 cubic feet, and from 1879 to 1901, 

 91.2 cubic feet ; for coppice and compound coppice, from 1892 to 1896, 

 55.1 cubic feet, and from 1897 to 1901, 65.7 cubic feet. , 



The German Empire, with an annual production of 48.7 cubic feet 

 per acre, shows the highest wood production of all European coun- 

 tries. Of the different kinds of forests, the state and crown forests 

 produce the greatest amount of wood per acre per year — 63.6 cubic 

 feet against 39.9 cubic feet in private forests. At the same time the 

 state forests produce the largest percentage of saw-log timber — 57.1 

 per cent against 53.1 per cent in private forests. Of aU the States 

 Saxony produces the largest proportion of saw-log timber. The dif- 

 ferent States may be arranged in the order of their production of 

 saw-log timber as follows:

Although Prussia includes 59.1 per cent of the forest area of the 

 Empire, it furnishes only 47.6 per cent of the total production of 

 timber over 2| inches, and only 48.3 per cent of the timber production 

 of the Empire ; in each case less than half. 



Bavaria, Wurttemberg, Baden, Alsace-Lorraine, Hesse, and Saxony, 

 which together include 33.5 per cent of the total forest area, produce 

 44 per cent both of wood over 2f inches and of timber. 



The largest percentage of saw-log timber does not necessarily mean 

 production of the largest amount of all kinds of wood over 2| inches 

 in diameter at the small end.
