The better development of the pine on the disengaged plot is 

 evident from the much greater percentage of pines with free 

 crowns and in more rapid growth in height. In 191 1 64 per cent, 

 on Plot II ; 72 per cent, of the pine on Plot I were over six feet 

 in height, while only 54 per cent, on Plot II were over six feet. 

 In addition to this, a large part of the overtopped pines, especi- 

 ally those overtopped by hardwoods on Plot II appear weak or 

 sickly and many are distorted by suppression. The pines on the 

 disengaged plot are uniformly healthy, vigorous and straight. 



*Only 238 of these pine overtopped by hardwoods, the rest overtopped 

 by pine.
