 forty in width. The slate is of a very compact kind, and must have re- 

 quired a powerful convulsion to have separated it. The walls are perpendi- 

 cular, and correspond with much exactness. At the bottom there is a 

 spring of cold water, and a cave of some extent. As you enter the 

 dhasm, you are struck with the romantic beauty of the spot. Above, it 

 is completely over-reached with lofty pines (Pinus strohus) and hemlock 

 (P. canadesis), together with stately walnuts, {Juglans porcina) and 

 butter-nuts, (Juglans cinerea) &c. &c. while below, the ground is 

 adorned with a great variety of plants, and the rocks with numerous 

 species of mosses, lichens, and ferns. These, together with its coolness 

 and entire solitude, make it a very pleasant retreat in summer. It is 

 called Wolf Hollow, from its formerly being a famous haunt for wolves.
