 open air for several months and permitting the moisture 

 to evaporate gradually, or as in most modern mill? the

 completed the lumber is then sorted and piled, awaiting 

 shipment, and is ready to be made into houses, furniture 

 or put to any of the countless uses which make the 

 products of our forests so necessary to our civilization.
