2 THE WHITE PINE 



iu localities where lumbering operations were 

 in progress, so that the figures could be col- 

 lected as the trees were felled and sawed into 

 logs. Thus a large number of measurements 

 were taken on Lick Run, Clearfield County, in 

 the Pine Creek district of Lycoming County, and 

 in a large windfall on Naval Run, a short dis- 

 tance above Slate Run station, in Tioga County. 



The notes on the second-growth Pine were 

 taken in Pennsylvania upon the high plateau 

 south of Driftwood, Cameron County, near An- 

 sonia in the Pine Creek district of Tioga County, 

 and in Lycoming County on the plateau above 

 Otter River. Valuation surveys of a few groups 

 in Franklin and Clinton Counties, New York, 

 were used in the preparation of the yield tables. 



The localities where the data were obtained 

 varied in altitude from a few hundred to nearly 

 two thousand feet above the level of the sea. 

 A more detailed description of the habitat of 

 the White Pine in central Pennsylvania will be 

 found farther on. 



It should be noted that the area where the 

 measurements were taken is comparatively re- 

 stricted, and that the number of trees examined 

 is not large in comparison with that used in the 

 construction of tables for certain European 

 trees. Nevertheless the scope of this study is
