thick of the trees. In this direction the outlook may extend, if the 

 air is especially clear, to Sideling Hill about sixteen miles distant. 



The ridges between these two heights consist to a large degree of 

 shales, and are left in their forested condition because of the unsat- 

 isfactory character of the soils for farming purposes, and afford 

 therefore an opportunity for seeing the character of forest which is 

 likely to have been common in the whole Upper Midland Province 

 at the time of the settlement of St. Mary's City by the first Mary- 

 land Colonists. 



Valleys. — In the valleys formed between the main elevation of 

 North Mountain and the subordinate ridges on the east side, there 

 are present such trees as are indicated in the list below, and it will 

 be noted that the species represented are not materially different 

 from preceding woodland lists. There is, however, a considerable 

 difference, not evident in the enumeration of species, due to the pro- 

 portions of the chief members of the forest flora, although there is 

 close similarity between this and the east side of the Blue Ridge, near 

 Sabillasville or Buena Vista. The following species may be men- 

 tioned : 



Castanea doitata 

 Hicoria ovata 

 Platanus occidentalis 

 Comas florida 

 Pinus pungens 

 Pinus virginiana 

 Liriodendron tulipifera 

 Hicoria alba 

 Juglans nigra 

 Nyssa sylvatica 

 Hamamelis virginiana 

 Tsuga canadensis 

 Quercus prinus 

 Quercus alba 

 Qurrcus coccinea
