393. Anonymous. Enhetliga inmatningsregler for rundvirke. [Uniform rules for measur- 

 ing round timber.] Skogen 6: 247-252. 1919. — Uniform rules have recently been adopted in 

 Sweden for measuring fire wood, pulpwood, and saw timber. Fire wood is measured in cubic 

 meters; pulpwood and saw timber may be measured either in cubic meters or in English units. 

 The rules also prescribe how different classes of material shall be piled for measuring. — G. A.

396. Anonymous. Das Papierholz. [Wood for paper.] Oesterreich. Forst- u. Jagdzeitg. 

 1926: 314. December 5, 1919. — Paper industry in Austria demands larger amounts of wood 

 every year and it is becoming difficult to secure within reasonable distance. Branchwood 

 and tops do not appear usable to any great extent. Trunkwood of rapid growth, having nar- 

 row fall rings and a light colored heart is a necessity for the manufacture of high grade paper.

 (Drying and preserving wood by electricity.) Deutsche Drechsler Zeitg. 2. 1915.] Oester- 

 reich. Forst- u. Jagdzeitg. 1922: 294. Nov. 7, 1919. — A current of electricity passed 

 through green wood oxidizes the resinous components of the sap, causes a physical change in 

 the wood structure that makes it stronger and more resistant to decay and kills all decay 

 spores, rendering the wood aseptic. In practice the freshly cut wood is placed in piles not 

 over 1 or 1.5 meters high through which a current of 80 to 100 volts is passed transversely. 

 Three to 6 kilowatts per cubic meter are required to complete the treatment. — F. S. Baker. 



400. Anonymous. Why there is a limit to forests. Sci. Amer. 121 : 191. 1919.— It is held

 pansion, which has produced greater wealth than did the forest industries in their prime. —
