ering. Absence of pines except on xerophytic bluffs, of Black Jack 

 Oak, and scarcity of Sweet Gum and Spanish Oak, also characterize 

 this soil. 



Sassafras Loam. Highly characteristic are White Oak, Sweet 

 Gum, and Red Maple, while the Black, Swamp, Chestnut and Wil- 

 low Oaks are plentiful. Black Gum usually accompanies the Sweet 

 Gum and Maple. 



Windsor and Norfolk Sand. Scrub Pine is more apt to occur as 

 a lasting stand on the sand than on the heavy loam. Chestnut and 

 ( 'hinquapin are especially characteristic. The White, Post and 

 Spanish Oaks and Yellow Locust occur frequently; the Tulip Tree 

 is especially apt to occur on moist slopes. 



Susquehanna Gravel. Under the highly xerophytic conditions 

 caused by this soil only Scrub Pine and Spanish Oak occur with 

 frequency. 



Meadow. By far the commonest tree is the Sweet Gum, although 

 near the coast in the southern part of the state, the Loblolly Pine 

 is very abundant. The Willow Oak is highly characteristic of this 

 region, while the White Oak is common though not characteristic. 

 The position of the streams is marked by an exclusive growth of 

 Alder, River Birch, Willows and Maple. Chestnut and the Tulip 

 Tree rarely occur, while Hickory is by no means common.
