May 1, 1910 CANADA LUMBERMAN AND WOODWORKER 157 study of the reproduction on our cut-over lands, and I am especially interested in his report. Some Details of Cut-Over Timber On one section of our best growing Crown lands, Dr. Howe re- ports as follows on the average of a number of sample acres studied: â 'This land was cut 25 years ago, and 37 spruce trees 12 to 20 inches in diameter were removed per acre. It was again cut 10 years ago, and 19 spruce trees 10 to 12 inches in diameter ; This means that approximately 56 trees or about five thousand board feet was removed from this land during the last twenty-five years. "There is now standing on this a total of 149 trees, 58 spruce trees per acre and 91 fir trees, over one inch in diameter, to provide the next crop. Of these growing trees 7 spruce and 8 fir trees are now of commercial size and if cut would still leave 11 spruce and 10 fir trees, which would reach comrriercial size during the next thirty years. That is, there are 36 trees to provide the cut for the next 30 ; Dr. Howe states that if all our cut-over lands gave as good a showing as this, there would be little cause for worry, but the following counts made in another part of the province will give many of us cause for thought, This locality was cut over three times, 30 years ago, 16 years ago and 4 years ago, and 97 spruce and 15 fir trees removed per acre averaging 8 to 18 inches in diameter on the stump. This means that 112 trees or probably between 9 and 10 thousand board feet or more was cut from this area during the last 30 years. The trees still standing on the area show an average of 108 s])ruce and 186 fir per acre over one inch in diameter, but there are only nine of these trees large enough now to reach commercial size during the next 30 years. Dr. Howe says "That this ha
