forest, 14,000,000 acres. In 1910, a decrease of the forest area 

 by 17,400 acres for farm and other purposes was almost fully 

 made up by planting of waste lands. Conifer forest represents 

 about 60 per cent , broadleaf 20 per cent , and mixed forest 

 another 20 per cent. Very nearly 60 per cent is high forest., 

 27 per cent selection forest, the rest coppice and composite. In 

 the high forest the yield per acre (increment) was only 45.7 cubic 

 feet, of which 58 per cent was workwood; the lower yield of 

 coppice (33 cubic feet) reduces the total increment to 44.3 cubic 

 feet. 



Besides the 8,400,000,000 cubic feet of wood (with 53% 

 workwood), the forests furnished 1,300 hundred weight of oak 

 bark and 75,800 hundred weight of spruce bark; 1,244,000 

 hundred weight of litter, over 4 million pounds of rosin and tur- 

 pentine, and 10,000 pounds of seed. 



Fire destroyed 900 acres of old stands and 1,150 acres cultures; 

 some 90,000 acres suffered from insect pests, and 250,000 acres 

 from wind and snow. 



The chase alone occupies some 40,000 professional hunters. 

 Over 130,000 pieces of "high game," some 2 million hares and 

 rabbits, more than 1.7 million game birds represent the game bag.

Amplifying the data brought together by 



Forests the committee on the status of Swiss forests, 



of of which Prof. Decoppet is chairman (see 



Sufitzerland F. Q. XII, p. 286 ff.), the following statistics 



are taken from the committee's report. 



Of the productive area of Switzerland 30 per cent is covered 



with forests and three-fourths of these are productive forests. 



Four and one-half per cent are controlled by the State, 68 per 



cent belong to communes, and 27 1-2 per cent are in private 



control. 



On account of the heavy precipitation and the favorable climate 

 the growth is rapid. Furthermore the diversity in soils and range 

 in elevation give a variety of species. However, only 30 per cent 

 of the forests are deciduous. In order to obtain their maximum 

 value 90 per cent of the forests are handled as high forests. The
