1615. BoRNEMANN, Crist. Ernst. Ist cs wirklich paradox, daferner Eichen-und Biichen- 

 holz anzuziehen, wo viele Jahrhundert grosse und geschlossene Eichen- und Biichenwaldungen 

 gewesen, und streitet solches so sehr gegen Analogie, Erfahrung und Natur, als in 43ten und 

 44ten St. dieses Magazins angegeben worden? [Is it really a paradox to reproduce oak and 

 beech in localities formerly occupied for centuries by large and dense stands of oak and beech, 

 and does this argue so strongly against analogy, experience, and nature, as was indicated in 

 the 43rd and 44th issue of this magazine?] Zeitschr. Forst- u. Jagdw. 51: lOG-109. 1919. — 

 Forest soils contain, partly in themselves, partly as supplied by the existing stand, enough 

 elementary ingredients to perpetuate and reproduce oak and beech stands. Otherwise such 

 stands could not continue in the same locality for centuries, when the trees do not seed farther 

 than the periphery of their crowns. The writer considers failures as due entirely to specific 

 local conditions which hinder reproduction. — J . Roeser.

 1921. — Forestry in Spain dates from 1835. The practice is more along aesthetic lines than 

 in any other country. The forests consist very largely of pine and oak, though Eucalyptus 

 and California redwood are common. In reforestation the European poplar is used exten- 

 sively in the lower valleys and maritime pine in the mountains. Of the scant 12,000,000 

 acres of forest, properly so called, practically | are privately owned. — Chas. H. Otis.

1620. Crahat, N. I. La question forestiere, question mondiale. [The forestry question 

 is world wide.] Bull. Soc. Centrale Forest. Belgique 23: 259-263. 1920. — Inasmuch as the 

 world supply of wood is being consumed at an alarming rate, the attention of the League of 

 Nations should be directed to the necessity of conserving the forests and to the afforestation 

 of unproductive lands. The treatment of the forests on watersheds of international rivers 

 should be governed by treaties. Only 8 countries (Austria, Hungary, Norway, Sweden, 

 Finland, Russia, U. S. A., and Canada) are exporters. The reserve is already threatened, 

 and only 3 countries (Sweden, Finland, and Canada) have a future in exports. — W. C. 

 Lowdermilk.
