1604. Anonymous. Das Ergebnis der Harzgewinnung in Preussen. [The yield from the 

 resin industry in Prussia.] Zeitschr. Forst- u. Jagdw. 51: 415-416. 1919. — For the fiscal 

 year 1918, 2,288,661 kgr. of pine resin were produced at a cost of 4,187,186 marks, and 63,416 

 kgr. of Norway spruce resin at a cost of 42,434 marks. The net profit from the former was 

 117.05 marks, from the latter 83.08, and from Norway spruce wild resin (Fichtenwildharz) 

 50.95 marks per 100 kgr. It is believed that these returns should induce private forest owners 

 to devote their holdings to the production of resin. — J. Roeser. 



1605. Anonymous. Forestry in the Union. The progress of state afforestation. Jour. 

 Dept. Agric. Union of South Africa 3: 155-159. 1921. — The policy of the Forest Department 

 is to protect and conserve the indigenous timber forests and to utilize their products in such 

 a way as to increase future productivity. The supply of timber will gradually become ex- 

 hausted from these forests, which reproduce comparatively slowly. The future of forestry 

 in South Africa therefore lies in the plantations of exotic trees, which are gradually being 

 extended. — E. M. Doidge.
