remain, the cutting makes possible a higher number of trees per unit 

 of area, a more complete utilization of growing space, and consequently 

 a better quality of tree. The net result of the operation is to convert a 

 stand which was prospectively composed of inferior hardwoods into 

 one which would at maturity consist largely of white pine. 



To show the tabulated records for the remaining older plots would 

 require an unreasonable amount of space. Therefore, since with the 

 type in question it is the final percentage of white pine which really

fixes the value of the crop, the condition of the stand in the remaining 

 two plots, as well as in that just discussed, is shown by a tabulation 

 with respect to white pine alone.

In Table 4 are summarized the numbers of white pines on each of 

 the three plots, according to the crown classification used above. There 

 is also noted for each plot the quality of the site. Even making liberal 

 discount for original differences in the number of trees per acre, this
