The Gro-iving of Eucalypts. By Fred G. Plummer. Vol. V, 



No. I. 



Here is what a man wants to know before planting Eucalyptus. It is 

 a general article followed by eleven pages of bibliography of Eucalyptus, 

 so will serve as an excellent reference for anyone wishing further infor- 

 mation on these important trees. 



Experiments in Sandhill Planting. By Carlos G. Bates. Vol. 



V, No. I. 



This article shows very distinct progress in forestry thought and prac- 

 tice. It is detailed, specific, and extremely instructive. The author gives 

 a series of very interesting experiments which were made in such a way 

 as to show how each factor acts and why. The effect of plant competition 

 on the moisture supply is particularly interesting. The article is, there- 

 fore, pure forestry of great future value, not only for the sandhills of 

 Nebraska, but for every other region, as suggesting lines of investigation 

 to be followed anywhere. 



Hardy Catalpa; a Study of Conditions in Kansas Plantations. 



By A. E. Oman. Vol. VI, No. i. 



The author gives interesting and instructive details concerning the 

 starting and care of hardy catalpa stands. He treats the subject in a 

 careful and detailed manner, giving the causes of all the facts and recom- 

 mendations he brings out. The article is tJierefore a valuable addition 

 both to the forester's and farmer's knowledge of handling this valuable 

 tree. 



Eucalyptus Possibilities on the Coronado National Forest. By 



R. L. Rogers. Vol. VI, No. i. 



A thorough knowledge of conditions on the Coronado help to make 

 Mr. Rogers' article of interest and value. He shows clearly that, although 

 certain species of Eucalyptus can probably withstand the temperatures, 

 it is doubtful if they could endure the drought unless previously estab- 

 lished by irrigation. His conclusion is the need for thorough experimen- 

 tation. The article is written in a careful scientific spirit, and should be 

 read by all foresters who have under consideration the planting of 

 Eucalyptus in arid regions. 



Seed Production and How to Study It. By Raphael Zon and 



C. R. Tillotson. Vol. VI, No. 2. 



This article is the result of painstaking and scientific effort. In the 

 first place the authors state the four problems involved. The mere state- 

 ment of these problems is a stimulus to forestry research. The history 

 of the study of seed production is given in detail from its beginning to 

 the present time; presented last is Zon's and Tillotson's method of study- 

 ing seed production, which, briefly, consists in determining the per acre 

 production of seed for any given stand. The method is somewhat com- 

 plex and the idea is not concurred in by all foresters (see discussion 

 of this article in Vol. VII, No. i). Nevertheless the article has vigor 

 and originality and marks a distinct step forward in the professional 

 thought of the country.
