The figures given in Table II were taken in a culled hardwood 

 stand which was cut over some 20 years ago. Trees were selected 

 for these growth data which would fairly represent the growth

 next cutting was determined. By averaging the growth percent

 this average to the total volume to be left, the figures shown 

 in Table III were derived. It should be remembered 

 that these figures include only trees over 7 inches in diameter
