Regenerated during the First Period, while the young compartments 

 feliould, during the same time, be subjected to Improvement Cattii^s, 

 viz.. Cleanings and Thinnings. Similarly ire may collocate in tl»e 

 last Block, with quite young crops, exploitable trees, whetbe* these 

 grow apart from one another or form continuous leaf-canopy. 

 Under such circumstances, these latter would be exploited during 

 the First Period in order to effect the desirable uniformity. 



(2.) Supposing that in the pine forest which we considered 

 higher up a fine crop of poles is, onder unavoidable necessity, 

 placed in the First Block, because it is enclosed on every side by 

 the great mass of exploitable compaitments. Is it necessary to 

 regenerate it during the First Period in order to eflect the 

 regularization of the age-classes in the shortest possible time ? We 

 answer. No ; because to do so woold be to incur a great sacrifice 

 for an entirely secondary object ; and besides this, there is nothing 

 to prevent the same difficulty recurring through some unforeseen 

 cause. Under th^e circumstances the Organisation Project should 

 confine itself simply to prescribing Thinnings, and leave to those, who 

 will revise it at the end of that Period, the task of proposing the 

 treatment that wiU then be found to be necessary. 



(3.) We will now suppose that we have a compartment 

 Containing mature and decaying timber, and that this compartment 

 stands in the very heart of the Thii-d Blooki Here the procedure 

 would be the same as in a crop that is still young but overtaken by 

 premature decay. 



(4^ We will suppose that in order to give the most convenient 

 foi-m possible to the first two Blocks of a Working Circle exploited 

 on a rotation of 160 years, it is considered neces.sary to collocate in 

 the First Bt^ck a compartment aged 100 years, and in the Second 

 a neai'ly equivalent compartment composed, however, of timber 

 150 yeai-s old. It would certainly be advantageous, as far as the 

 produce alone is concerned, to exploit the compartment placed ia 

 the Second Block daring the First Period, and that placed in the 

 First Block during the Secoh i Period. However it be, before this 

 change of order could be proposed, it would be ne-essary to ass-ire 

 oneself that there would be no danger to fear from the action of the 

 wind in consequence of this infraction of the Rule« for locating 

 coupes.
