THE WHITE PINE REGION 307 



as a whole higher figures are shown for the Massachusetts section. 

 Inasmuch as the government figures are average for the whole 

 region they might be best compared with Quality II sites in 

 Massachusetts. However, it is beheved an average site for the 

 pure white pine type throughout the region would be below 

 Quality II (Massachusetts), so that the United States Forest 

 Service figures should be lower than Quality II in Massachusetts. 

 As a matter of fact the Forest Service figures start at twenty-five

 fifty years. At fifty-five years the Forest Service figures give a 

 higher yield, and in five years more they have jumped up and

 tendency for the first sixty years entirely different from the New 

 Hampshire and Massachusetts figures, which in relative rate of 

 growth are alike, although differing in absolute figures. The 

 government figures indicate a poor utilization in young stands 

 and would seem to have been improperly distributed between
