comprises everything that is not specifically assignable to the other 

 three classes. Here problems of forestation, forest influences, 

 management, protection, mensuration, regional studies, silvical 

 studies, tree studies, and liunbering find their harbor. From time 

 to time, a Review of Forest Investigations is published ; so far 

 only volumes I and II have appeared in 1913, and it appears that 

 then this useful publication has ceased. 



Here the organization of the direction of this work is given. 

 The projects are submitted annually by District Investigative 

 Committees, composed usually of one representative of each of the 

 major lines of investigation and one supervisor of technical 

 training, and are based upon recommendations made by the differ- 

 ent Branches represented in the District organization submitted 

 to the Forester. The programs are reviewed by the branch chiefs 

 of the central office, and then submitted to the Central Committee 

 of three members, which merely amalgamates and revises the 

 program, suggesting improvements in the procedure, and outlining 

 the investigative policy for the entire Service. The Review also 

 discusses objects and methods of the different lines of investigation. 



For the products investigations, as is well known, the elaborate 

 laboratory at Madison, Wis., serves mainly, while for the silvi- 

 cultural studies a number of small experiment stations are equipped 

 which it is proposed to enlarge so that a wide range of experiments 

 may be carried on. A distinction is made between administrative 

 experiments having in view answer to specific problems of some 

 locality, and investigative experiments trying to establish broadly 

 applicable principles. The Committee of 1914 recommends en- 

 largement in the latter, reduction in the former class of investiga- 

 tions. 



The Investigative Program itself is a bulky voltmie of 100 closely 

 printed pages. In this program every project is briefly described 

 under ten headings, namely a brief statement of the project; its 

 object; cooperation, if any, \\ith outside agencies; location; 

 status of investigation ; plans for further work ; use to be made of 

 resiilts, publication or otherwise; probable date of completion; 

 assignment of the investigation to various stations or agencies or 

 investigators, proposed expenditures. 



To scrutinize critically such an elaborate program would take 

 more space than we can afford. Suffice it to say that as far as 

 organization is concerned it is made on a great scale, and, if the
