 were not infrequent further east, as the Bear Oak here rare, the 

 Chinquapin (one station only found), Comptonia, peregrina (infre- 

 quent) and Rubus odoratus (seen at one locality). 



There are a number of outcrops of the white sandstone of the 

 Tuscarora formation, such as occurs in Wills Mountain at Cumber-

 lichens.
