FOREST REGULATION AND YIELD 139 



has permitted the executive officers to locate fellings area in 

 the parts altogether too elevated, where the regeneration will 

 be problematic." 



In 1840 there were listed 391,591 cubic metres (13,828,644 

 cu. ft.) of saw logs and 707,079 steres (24,969,758 stacked cu. ft.) 

 of fuel; in 1896 the total growing stock was 567,217 cubic metres 

 (20,030,701 cu. ft.). For the 13 years prior to 1900 the yield 

 in francs was 25,079.09 ($4840.26) but the 1900 working plan 

 (Part V) reduced the allowable annual yield to 11,746 francs 

 ($2266.97), or less than half. The precaution had been taken 

 to cahper the defective and sound trees separately, to drive 

 home the past error of cutting the yield from the best 

 timber. 



In explaining the necessary reduction in cut the 1907 Mar- 

 mano plan reviews the past yield: 



1858 to 1870 3000 cubic metres (105,942 cu. ft.) excluding ^^ 



tops and branches. 

 1871 to 1882 2 1 14 cubic metres (74,654 cu. ft.) excluding 



tops and branches. 

 1883 to 1907 483 cubic metres (17,057 cu. ft.) excluding 



tops and branches. 

 1908 767 cubic metres (27,086 cu. ft.) excluding 



tops and branches. 



Some forests, according to de Lapasse, were deliberately 

 overcut in order to pay for the road system, but these have 

 now recovered. One of the greatest drawbacks was the poor 

 market, which apparently made it necessary to leave un- 

 sound trees standing because only the best timber could be 

 sold. 



Production. — The production for the forested area amounts 

 to but 0.950 cubic metre (33 cu. ft.) per hectare per year for 

 the total areas. The annual production may be summarized : ^^ 



^ Tops and branches are usually calculated at 10 per cent of the stem; but 

 the unsound trees are estimated to contain only one-fourth their total volume in 

 merchantable material.
