Nearly mature stand of Poplar (8 to 12 inches in diameter, 40 to 50 feet in 

 height), under which a full reproduction of Spruce has taken place. As the Spruce 

 saplings are in some cases already suffering from suppression, the Poplar should be 

 at once cut clear. This would usually be a j^rofitable undertaking, since the market 

 for Poplar at excelsior mills and limekilns is good.
