preserved is preserved, and often even in the coppice crops, the 

 -exploitation of which falls due at a more or less distant date. But 

 durino- the following Period (the First Period, that is, of the con- 

 version), the necessary provision has to be made by the establish- 

 ment of a Reserve Fund, just as is done, as we have already seen, 

 in the organisation of already constituted high forest. For the 

 annual increment neglected in the estimation of the yield a full or 

 partial compensation will be found in the promising oaks reserved 

 at the exploitations, which trees will not, as a rule, be felled for a 

 half century at least. It is, therefore, absolutely necessary, iu 

 establishing a Reserve Fund, to draw upon the actual stock. 



If, moreover, during this same Period the large trees of the 

 last Blocks are preserved in the coppice exploitations, if, in fine, 

 the Second Block has been well ptovided for by the Organisation 

 Project, and worked accordingly with a sparing hand, it is evident 

 that the increasing richness of the forest vrill cover any threatened 

 deficit. The same economical spirit observed in each and every ex- 

 ploitation, and the addition, whenever necessary and as they become 

 available, of a few individuals from among the trees left standing in 

 the Secondary Fellings will never fail to secure a sustained yield 

 during the subsequent Periods. 



We may, therefore, take it for granted that with the close of 

 the Preparatory Period the essential basis of the conversion has 

 been achieved, and that during the First Period of the actual con- 

 version a decisive step has been made in a definite path clear of 

 all difficulties and obstacles. Provided the cultural operations have 

 been well executed and a spirit of economy has presided through- 

 out the organisation as well as the treatment of the forest, the im- 

 provements realized will be found to be already extensive, and the 

 success of the undertaking fully assured. An entire Block covered 

 with a young seed-grown forest, another portion of equal extent 

 well stocked with exploitable timber, and, lastly, the rest of the 

 forest modified in the happiest manner by two coppice exploitations, 

 that have left iu it a numerous reserve of long-boled hardwood trees 

 — such are the results accomplished. The stock and production of 

 the forest have already undergone a complete transformation, and 

 the elements for a successful conversion multiplied to the highest 

 degree desired.
