CHAPTER TI. 



ORDER TO OBSERVE ITST THE EXPLOITATIONS. 



oMXo 



Once the exploitable agB of a Working Circle has been deter- 

 mined, we know at once what descriptions of produce we may 

 expect to obtain from it. We are then in a position to direct the 

 exploitations in such a manner, as never to cut anything- that is 

 not exploitable, a condition that is in reality the very first that 

 every Organisation Project ought to satisfy. But the order in 

 which the various crops should be successively removed is a matter 

 of no little importance. The order in which the compartments 

 ought severally to be taken up, is first of all indicated by the age 

 and promise of the standing stock. But, on the other hand, 

 the location of the coupes is subject to certain special rules, the 

 observance of which is always useful and sometimes obligatory. It 

 thus happens that in order to conform to these rules, it is often 

 found necessary to modify the successive order of the cuttings, 

 which a consideration of the age alone of the crops would require. 



The Rules for locating coupes belong to the province of 

 Sylviculture, in works on which art they will be found enunciated 

 and discussed. They have been drawn up in as simple and general 

 a form as possible. The objects to be secured by observing them 

 and the results consequent on their being neglected are clearly 

 defined in such works. These Rules are not, however, entirely 

 cultural in their scope, and belong equally to the subject of Forest 

 Organisation, in which art they occupy an important place. We 

 have already had occasion to refer to them in treating of the 

 formation of compartments and the constitution of Working Circles. 

 And we shall be confronted by them at every new step we make 

 in the theoretical study of Forest Organisation, as well as in the
