It will be observed that an enormous amount of coniferous 
material exists which under present conditions possesses hardly a 
market value. Most of this material is good both for lumber 
and pulp and it is to be hoped and expected that its loss by fire 
and otherwise will be averted. 
PRESENT ACCRETION OR INCREMENT. 
In North Wisconsin a grove of w r ell grown sapling timber 
60 years old, of pine, may be assumed to cut at least as much 
as 15 cords of bolt size material, or about 6 M. feet B. M. per 
acre. In the old woods as they stand, the trees above sapling 
size represent the great mass of the wood material and therefore 
the growth of wood is largely on trees nearly or quite of log 
size, so that the same amount of growth per acre here adds
