Periodical Literature 633 



He added: "The fight about the theory, it is to be hoped, will 

 soon be a thing of the past; its practice in the forest belongs to 

 the future." 



Unfortunately the fight about the theory is not yet over. 

 Opponents of the soil rent theory are still active as witness the 

 periodical literature on this subject. However, Wimmenauer, after 

 carefiilly reviewing the matter, sees no reason to change the stand 

 he took twenty-seven years ago (in common with Pressler, G. 

 Heyer, Judeich and Martin) that it is the task of forest manage- 

 ment to strive for the highest interest return on the forest capital 

 possible with the species and the silvicultural system. 



When it is remembered that Dr. Wimmenauer preceded his 

 academic activity with twenty years of practical experience, this 

 result of forty-seven years of well-balanced thinking will not be 

 weighed lightly.

UTILIZATION, MARKET AND TECHNOLOGY 



Last year a peculiar association was 



Railroad Ties formed in Germany, the Beech Industries 



in Germany Association, excluding from it the firms 



which handle railroad ties, who make 



imdesirable competition to the other industries, stimulated by 



increase in prices of the latter. With the reduction in the offerings 



of oak ties, the use of beech ties is increasing. Yet in the contracts 



for ties made last fall, for this year's delivery, prices have somewhat 



decHned. 



To cover the requirement of the Prussian railways of 840,000 pine 

 ties and 314,000 hardwood ties, over 3,900,000 pine ties and 

 1,210,000 hardwood ties were offered, but of these only 143,800 

 foreign oak ties. On pine ties an increase up to 11 cents (price 

 varying much with locality) was experienced, but beech ties, 

 while as a rule from one-half to 10 cents dearer, in some places 

 show slight declines. 



Prices for pine ties ran as a rule between $1.10 and $1.20 and for 

 foreign ties a little lower; creosoted ties are from 25 to 50 cents
