Experiment Stations in Connection With the National Forests. 



By S. T. Dana. Vol. IV, No. i. 



The author shows the far reaching significance of the new (this was 

 in 1909) plans of establishing experiment stations on the National Forests, 

 and touches upon some of the problems requiring solution. The estab-

 the Forest Service in placing the profession on a firm foundation. The 

 value of the information which these stations will some day secure cannot 

 be over-estimated. 



A Study of the Reproductive Characteristics of Lodgepolc 

 Pine. By Gordon E. Tower. Vol. IV, No. i. 



The author gives basic facts concerning the reproduction of lodgepole

 was at first supposed." He discovered two forms: (i) that occurring 

 on lime soils with cones difficult to open; and (2) that occurring on silica 

 soils with cones opening readily. He also gives data on the effect of heat 

 and of age of the seed on the power of germination.
