506 APPENDIX 



On the other hand, because of the construction of the Frasne-Vallorbe railroad, the 

 areas of the compartments enumerated below are reduced as follows: 



Hectares Hectares Hectares 



Compartment 1 = 21.82 - 0.26 = 21.56 

 Compartment 12 = 6.93 - 0.23 = 6.70 

 Compartment 17 = 6.66 - 0.17 = 6.49 

 Compartment 23 = 17.26 - 0.14 = 17.12 



HE GENERATION FELLINGS 



Art. 6. — Special fellings schedule for a period of 32 years, 1913-1944. — The 



essential aim of the shelterwood method is to replace a mature stand by young growth 

 and the cultural difficulties which accompany this realization consist in its creation 

 rather than its development until the merchantable age. In order to attain this result 

 it is necessary to mark in the first place the regeneration felling; in order to assure its 

 regular and methodical execution, there have been set aside each year for this operation 

 a quota of the pre-determined yield. This share is fixed at 1,290 m. c. 



The compartments of the first group include 41,068 m. c; this growth is not counted 

 in order to make allowance for the polewood which can be conserved. 



To realize on this volume there will be needed ' = 32 or 32 years for the annual 



felling; the exploitation plan will then be 32 years (years 1913-1944). 



The regeneration feUings will be carried out: 



(a) As final fellings in compartments 12, 13 and 8; (6) as secondary fellings, then 

 as final fellings in compartments 2, 3, 4, and 7. They will be laid out gradually in the 

 order indicated above conforming to the rules; they will not pass from one compart- 

 ment to the next one until after it has been entirely cut over. 



IMPROVEMENT CUTITNGS 



They will take place in the compartments of the second and third groups which will 

 be cut over so far as possible within 10 or 12 years and in the following order: 20, 21, 

 1, 22 to 27, 5, 6, 11, 9, 10, 14, to 19. The yield will be recruited after deducting the 

 regeneration fellings and the chance cuttings; the area of the aimual feUing area will 

 depend on the volume remaining to be marked. 



Art. 6. — Application of the yield. — In order to realize the yield the local officers 

 should at the start mark the regeneration felling. The volume of the timber 0.60 m. 

 (7 inches d. b. h.) and above in circumference cut under this head being known and at 

 most equal to 1,290 m. c. they will add to it (if there is any) the volume of windfall 

 and overmature timber sold or marked during the current fiscal year. The total will 

 be deducted from the ordinary yield and the result of this subtraction will show the 

 amount to be cut under improvement fellings. All these volumes will be calculated 

 by the volume table used for the valuation of the forest. 



Revision of the Yield. — The yield will be revised for the year 1944 or (if there is 

 any) for half the period assigned to the felling schedule in 1930. 



Cultural Rides. — Generally the regeneration and improvement fellings will be 

 laid out in accordance with ordinary cultural rules. It seems necessary, however, to 

 call local officers' attention to the following points: 



Regeneration fellings —first group. — These feUings must aim to form a young stand; 

 seeding of the soil and the substitution within a given period of seedlings, thickets, 

 saplings, and yoimg polewood for the existing high forest.
