the paper-pulp manufacturer is the most powerful 
ally of the forester, in that he uses the thinnings 
of the forest, which begin while the forest is still 
young and continue throughout its whole exist-

The newspaper referred to, and there are many 
others which use quite as much, consumes therefore, 
in one year, all the spruce on 16,225 acres of land 
as it grows naturally in our northern mountains. At 
this rate our spruce supply will fail in the course of

Common newspaper material is simply wood, from 
which bark and knots have been removed, which is
