102 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, 



work out, as far as possible, what the enemy's forest resources 

 are, and how we may utilise them. 



II. 



From official statistics of 1900 the total wooded surface of 

 the German Empire (omitting Alsace-Lorraine) was 13,556,037 

 hectares (1 hectare equals 2-47 acres), distributed as follows: — 



The species were as follows : — Broad-leaved species of various 

 kinds— among which oak high-forest occupies 5-2 % of the total 

 wooded area — cover 267 % of the area; conifers occupy 737 % 

 (46-6 % Scots pine, 24*6 % spruce, 2 % silver fir). 



I now will show how I consider we may estimate these 

 resources for immediate realisation. 



III. 



The above-cited statistics also indicate, for all categories of 

 forest and for the chief species, the area occupied by woods of 

 different ages. I extract the following : — 



Surface occupied, in thousands of hectares, by the woods of 

 the empire (omitting Alsace-Lorraine) — 



There are thus in the German forests, in round numbers, 

 3,568,000 hectares of over 60 years, of which about half is 

 Scots pine, over a quarter beech, and a fifth spruce. 



If we consider specially the State forests we have the 

 following figures, shown separately for Prussia and for the 

 whole of the empire.
