But it is not with the living tree that our present subject has to do — all of that belongs to the province of Forestry — but rather with the product after the tree has been cut down and sawed into lumber or other forms of wood. Lumbering and Forestry are not an titheses, but both Should accomplish the same result, the perpetuation of the forest for future use, whatever that may be. Lumber is a crop, as are vegetables, and the forest may be utilized, and at the same time conserved for future use.
