STATE AND OTHER FORESTS OF FRANCE. 77 



preparatory cuttings by area in the second periodic blocks and 

 in a part of the third; coppice cuttings in the fourth. 



This scheme of management has for a long time been sub- 

 jected to modifications of detail only, bearing principally on the 

 yield of the cuttings by volume. In the first block (2377 acres), 

 which is attached to the Experimental Station of the National 

 Forest School, a plot of 1657 acres was, by decision dated 

 17th February 1887, detached from the fourth working- 

 section, to be subjected as an experiment to the method called 

 that of Control. The actual condition of the crops does not 

 always lend itself to the immediate application of this system. 

 It has not, up to the present time, been possible to do more than 

 pass over them by fellings made at intervals of six years, in which 

 IS removed a fixed volume, the amount of which is determined 

 by an estimate of cost, made also every six years. 



Without speaking of this experiment, still in its infancy, it 

 may be said that the system of management of the Forest of 

 Champenoux generally yields satisfactory results. On some 

 scattered plots natural regeneration could not be attained, but 

 it will there be supplemented artificially.
