THE STEEPER SLOPES. 



Thurmont. — Tlmrmont is situated in close proximity to the 

 steeper hills of the Eidge region, and there the streams have cut 

 ralleys that are steep-sided and rugged in many cases, affording 

 dense shade in the bottom, with usually a considerable degree of 

 moisture, both from the actual stream water, and from the tendency 

 of the damp air or foggy atmosphere to follow these drainage 

 courses in their movements to or from different levels. The pres- 

 ence of the Showy Easpberry (Rubus odoratus) is here noted for 

 the first time in going west, in the deep soil accumulated among 

 rocks, on the slopes of ravines or along roads, where the light is 

 stronger than in the deep woods. The Black Haw {Viburnum 

 acerifolium) is found in these along with the Purple species
