PART IV. — BETTERMENTS 



Only the absolutely essential betterments to be accomplished between 1913 and 1944 

 are listed : 



Management Lettering. — The compartments will be marked by painting letters 

 on a white background on boundary trees, work which may be estimated at 100 francs. 



Logging Roads. — The existing roads are generally in good condition and are suffi- 

 cient for logging purposes. Their maintenance requires an average yearly expense of 

 2,000 francs or for 32 years, 64,000 francs. 



Cultural Betterments. — First for restocking the blanks which may occur, and for 

 completing the natural reproduction if that should be necessarj^, it will suffice to esti- 

 mate the annual planting of 2,000 trees which will mean a labor expense of 15 francs 

 per thousand, or 30 francs and for 32 years, 960 francs. 



Secondly, these plants will be furnished by the nursery already established in the 

 forest. It has an area of 0.23 of a hectare and its annual maintenance amounts to 120 

 francs or for 32 years, 3,840 francs. 



68 900 



Total, 68,900 francs, or an estimated annual cost of ' = 2,153 francs ($416).

PART V. — COMPARATIVE REVIEW OF THE PRODUCTS TO BE REALIZED 

 BEFORE AND AFTER THE REVISION OF MANAGEMENT 



The Federal forest of Grande Cote has produced: 



From 1858-1883, 78,343 m. c, valued at 1,327,441 francs; 7.9 m. c. per hectare and 

 per year, or 134 francs. 



From 1884-1896, 25,377 m. c, valued at 395,033 francs; 5.1 m. c. per hectare and 

 per year or 82.2 francs. 



From 1897-1911, 48,790 m. c, valued at 924,960 francs; 8.5 m. c. per hectare and 

 per year, or 161.6 francs. 



Or for the 54 years, 152,510 m. c, valued at 2,647,434 francs; 7.6 m. c. per hectare 

 and per year, or 128.7 francs. 



This puts the average annual yield at 2,888 m. c, valued at 49,026 francs. In the 

 future, up to the time the working plan may be revised, the yearly cut will be 

 3,090 m. c. which should yield about 58,710 francs; in giving an average value of 19 

 francs per m. c. which has been the average during the past 15 years, the yield will be 

 a Uttle higher than for the period 1858-1911, but 5 per cent less than that for the period 

 1897-1911. This reduction is actually essential as has been explained in detail in this 

 report ; but there is every reason to hope that because of the generally very satisfactory 

 growth in the forest of Grande Cote, and due to the good results of the management 

 proposed, the yield will increase during future periods.

Near 'St. Die, Vosges, 34.01 hectares, 410-540 meters altitude, 9/10 fir, 1/10 beech. 



(A) Working group, Corne de Lisse, Masson's Method of Yield Calculation. 



During the first cutting period, 1890-1899, the yield was calculated in accordance 



2 V 

 with the formula P = -jr-, where P = yield; V = growing stock; andA''= rotation 



in years.
