Jiot yet been commenced. The duty of proposing the Improvement 

 Cuttings to be made in the portions already transformed and, therefore, 

 already regularized, may be left entirely to the Executive Officer, 

 no reference thereto being made in the Organisation Project. 

 The Cleanings, even when their utility is greatest, as, for example, 

 in a forest of mixed silver fir and beech, could not possibly be pre- 

 scribed ; while Thinnings, less useful in silver fir forests than almost 

 anywhere else, never assume an urgent character, and are, moreover, 

 it badly executed, extremely dangerous. In the majority of cases, 

 therefore, it is safer to leave them to those who are to execute the 

 Organisation Project : they can judge better than any one elsewhere 

 and when such cuttings should be made, and will undertake them 

 only M^hen their utility is unquestionable. To tie the Executive 

 Establishment down to carrying out a multitude of various opera- 

 tions, especially where mountain forests are concerned, would be 

 the greatest mistake the Amdnagiste could commit. 



It remains now to show how the yield of principal produce for 

 the duration of the current Period is calculated. This yield is 

 naturally derived from two sources, (i) the produce of the Trans- 

 formation Fellings, (ii) that of the Selection Fellings. 



The Transformation Fellings, which are before everything elsa 

 true Regeneration Fellings, ought to be based on volume. As a 

 rule, they remove all the formed trees, in other words, trees other 

 than mere poles ; to remove anything else would be defeating their 

 very object, which is to leaver after the cuttings have passed through, 

 young canopied crops capable of forming a harmonious whole and of 

 soon constituting a high forest little removed from the regular state.' 

 The Amdnagiste is thus obliged to include in his estimate of the 

 yield trees having a diameter of only 16 Inches, and even of 14 

 inches in the majority of cases. It is clear that if such trees exist 

 in any numbers, the transformation of the forest entails a heavy 

 sacrifice. However it be, the enumeration and measurement of 

 trees above a certain diameter affords the means of readily ascer- 

 taining the actual contents of the standing timber. The future 

 increment of these trees up to the time of their exploitation cannot 

 be determined in the same manner as that of canopied crops com- 

 posed of trees of the same age. If it is desired to take this future
