 Proceedings. 



The second number, which is just from the press, includes articles 

 on: 



Plants and Animals of Mount Marcy Charles C. Adams and others 



Influence of Temperature and Concentration on the Toxicity of Salts to 



Fishes Edwin B. Powers 



The Effect of Two Soil Temperatures on the Yield and Water Relations 



of Healthy and Diseased Bean Plants W. H._ Burkholder 



Anatomical Reduction in Some Alpine Plants C. C. Forsaith 



Notes and Comments. 



A study of forest types in the San Francisco Mountains of Arizona 

 will appear in the third and fourth numbers. 



The above list of articles is an index of the breadth of the field cov- 

 ered by the new journal. The -fact that the editor-in-charge is a 

 forester by training and that other members of the editorial board are 

 engaged in forestry research argues that silvics or the foundations of 

 silviculture will occupy an important place in its pages.

The Douglas Firs; A Botanical and Silvicultural Description of 

 the Various Species of Pscudotsiiga. By Henry, Augustine, and Flood, 

 Margaret G. Proceedings of the Royal Irish Academy, Vol. 35-B, 

 1930. 



For many years European taxonomists, in the revision of North 

 American genera which embrace arborescent species, have had the 

 tendency to split certain species of wide distribution into two or more 

 and to recognize names that the more conservative American taxono- 

 mists have long since relegated to synonomy. 



Professor Henry and Miss Flood have recently published a revision 

 of the genus Pseudotsuga which deals with the climatic and edaphic 

 features of the environment of each species as well as the anatomical 

 features which serve to separate them. Special attention is also given 

 to the silvicultural requirements of the several species, and their use- 

 fulness for planting in Great Britain.
