Fig. 7 (a). — Natural regeneration of spruce in the openings where it has sufficient 

 light. Under partial cover the seedlings have not as yet come in. 



(6). — Spruce stand in the Melezet Canton, communal forest of Villarodin-Bourget, 

 running 146 trees per acre and 109 cubic meters (36,000 feet board measure). Here 

 .selection fellings removed trees declining in vigor until openings have gradually been 

 made. Since the soil became partially sodded and covered with spruce needles no 

 regeneration has succeeded. Had the openings been made at once, instead of gradu- 

 ally, the reproduction would have been secured. 



(c)-(d). — Natural regeneration of spruce in the Melezet Canton, communal forest 

 of Villarodin-Bourget, at an altitude of 6,060 feet. No regeneration of spruce came in 

 after ordinary selection cuttings, which removed only a tree here and there. After a 

 windfall gave sufficient light (and wounded the soil) reproduction has succeeded in the 

 following proportions : Spruce, six-tenths; larch, three-tenths; cembric pine, one-tenth.
