Number of Trees Left. 



On areas adapted to a second cut, tabulation of actual marking 

 on 200 acres shows the following results : average stand per acre, 

 8,129 feet b.m. ; on forty acres, 347,292 feet b.m. ; average stand 

 per acre to be left after cutting, 1,805 feet b.m.; on forty acres, 

 79,300 feet b.m. Thus 22.2 per cent of the stand or 1,800 feet 

 b.m. would be left as against 7.5 per cent or 1,050 feet b.m. in 

 mature timber. The younger stands contained 1,051 trees 12
