In the Douglas fir region operators provide for the immediate restocking of cut-over timberlands by leaving seed trees in or adjacent to the harvested areas.

The inspection of lumber is a visual determination of the quality of the product. In the vigual application of the characteristics and limiting provisions of a grade, it is to be expected that.there will be some variation of opinion between inspectors. Experience has proven that a variation of 516 in the judgement of inspectors is a reasonable variation, and this tolerance has been adopted as standard practice in the lumber industry.

Since its organization in December, 1902, the National Lumber Manufacturers Association has served as a national voice of the lumber manufacturing industry.

The greatest threat to Tree Furrn. and all other forest lands is fire. Private forest landowners are spending hundreds of thousands of dollars yearly to restore land damaged as a result of carelessness with fire. Fire protection' equipment on Tree Farms is used primarily for the intensive protection of the individual Tree Farms but is available elsewhere in the event of catastrophe. \

The most satisfactory moisture content of wood at the time of gluing is that which, when increased by the moisture of the g1ue, approximately equals the average moisture content that the glued member will have in service.

In gluing thick pieces this relation can be attained, but in gluing veneer or other thin pieces the moisture added by the glue frequently exceeds the moisture content of the wood in service. Under the latter conditions the wood cannot be dried enough before gluing to avoid redrying of the glued products afterward.

The amount of moisture added to wood in gluing varies from less than 1 per cent in lumber to 45 per cent or more in thin plywood. The thickness of the wood, the number of plies, the density of the wood, the glue mixture, and the quantity of glue spread all affect the increase in moisture content of the wood.
