26 THE WHITE PINE 



The Oaks are the most important hardwoods 

 growing with the Pine, and of these the White 

 Oak {Quercus alba, L,) demands most attention. 

 Its qualities are too well known to require enu- 

 meration. Its growth is much slower than that 

 of the White Pine, and where it occurs in mix- 

 ture with Pine it is, as a rule, somewhat older. 

 The Pine then serves to force the height growth 

 of the White Oak, and in such cases we find it, 

 as well as other hardwoods, producing long 

 clean trunks. White Oak occurs on all kinds 

 of soil, even growing with the Rock Oak on 

 steep rocky slopes. It is a common tree on the 

 plateaus. 



Red Oak {Quercus rubra, L.) and Black Oak 

 (Quercus vehitina, Lam.) are found in mixture 

 with White Pine only on the better class of 

 soils. The rate of growth of the two species 

 was nearly the same, and for both it was better 

 than that of the Rock Oak or White Oak. 



The Rock Oak or Chestnut Oak {Quercus pri- 

 nus, L.) is intermediate in rapidity of growth 

 between Black Oaks and White Oak. It 

 reaches its best development on rich ground, 

 yet occurs in abundance on poor soils, and 

 is found mixed with Pine and Hemlock on 

 steep rocky hills, of which it is a character- 

 istic tree.
