stands except in the case of hillsides facing north and east, 

 where economic utilization demands that the logs be dragged 

 downhill and that the felling begin at the top or south or west 

 side. However, in such cases the exposure of the hillside re- 

 duces the danger from drying out to a neglible extent. 



This system marks a distinct advance in silvicultural practice 

 and can undoubtedly be successfully applied in America where 

 market conditions permit. However, its two disadvantages, the 

 need for a complete road system and the slow progress of the 

 cutting, will limit its wide application. K. W. W.

Interesting, from the standpoint of private 

 Private forestry, is the review of Kohler's eighth 



Forestry. brochure in the series "Our Forest Man- 



agement in the 20th Century." The au- 

 thor deals only with Wiirttemberg where, he points out, the pri- 

 vately owned forests constitute 21.5% of the total wooded area. 

 The net yield per acre of these private woods is only half that of 

 the Wiirttemberg State forests from which it by no means fol- 

 lows that under state management they would be twice as profit- 

 able ; for this would presuppose that they are by nature equally 

 productive, which does not necessarily follow. 



The author regrets the slavish imitation of the pure, even- 

 aged stands on the state forests, entailing departure from the 

 selection system for which the small parcels of private forests 

 are pre-eminently suited. To direct the proper management of 

 private woods, the author proposes that, following the example 

 of Prussia and Bavaria, administrative officers be detailed for 

 this special purpose from the Agricultural Department.
