that the mixture was not satisfactorily made by the arrangement in 

 rows, and used too many spruces, but mainly that a timely and judi- 

 cious thinning practice had failed to assist the development of the stand. 

 Possibly the soil, having been farmed, was unsuitable for the surface- 

 rooting spruce.

MENSURATION, FINANCE, AND MANAGEMENT 



At the end of a long discussion on the reor- 

 Modern ganization of the Forest Service of the Canton 



Organization of Neuchatel, just accomplished, the reviewer 

 formulates the aim of the management, which is 

 entirely modern and of special significance. It is not any more "to 

 assure the sustained yield," but to pursue "a continuous progressive 

 production." That is apparently meaningless, and yet it contains in 

 germ an entire revolution, which may mean the end of the "revolution" 

 (rotation) as a principle of management. It signifies, in effect, that 

 the management is to cease being doctrinaire, leave off scholastic forms, 

 and become experimental. It does not concern itself any more with 

 calculating the summary increment of the forests and basing on it a 

 fixed felling budget (possibilitc) which is to regulate the treatment, but 

 rather to apply a treatment to the forest, watch and study the accretion 

 in relation to the treatment, designed to bring each stand on the road to 

 maximum continued increment. It concerns itself with developing the 

 production by methodical and continued study of the variable influences 

 on accretion and deriving from it hints as to treatment. This study, for 

 which periodic detail inventories will furnish the material and the re- 

 visions of which in short periods will act as sign posts, obliges to make 

 one homogeneous body of treatment and management. 



The whole economics of the seven articles of the law having refer- 

 ence to the management and its frequent revisions tend to make the 

 permissible felling budget (possibilite) not any more the regulator of 

 the utilization. The treatment, silvicultural as well as technical, eco- 

 nomic as well as commercial, secures by these legal dispositions a lib- 

 erty of action such as a science which is based entirely on observations 

 and their application — that is, on experimentation — requires, a science 

 which to bring out its results requires as much art and intuition as 

 knowledge — a science which is at the same time a productive industry.
