solid rock, along each side of which a stream flows at the present time, 

 bordered by precipitous cliffs 50 to 75 feet high. The general direction 

 of this rocky ridge is north and south. 



The streams are united about a mile farther to the north, and after 

 passing along the sides of this marked rock elevation, they join in 

 the vicinity of Farrish's mill, and thus forming in reality an island, 

 which terminates at its southern extremit}'' in a limestone cliff. 



About 500 yards from the cave.s, and near the end of the bluff, 

 you suddenly come upon an immense hole in the solid rock ; it has an 

 oval form, its longer diameter being 20 feet and the shorter 15 ; one 

 side is 10 feet higher than the other ; it lies in a slight depression in 

 the rock, which terminates at the side of the hole, with an abrupt 

 fall of 22 feet. At the bottom of the hole you perceive an opening 4 

 feet high and 2 feet wide, but of an irregular outline, this opens into 

 a sort of valley, but it must be remembered this is 40 — 50 feet above 

 the level where the streams are flowing. This valley has rocks on 

 both .sides and forms a Vjeautiful glen, at the present time a popular 

 haunt for boys delighting to revel in the pastimes of youth. 



Following in a south-west direction for some GO yards the rock 

 rises, and a little farther on ends abruptly with a fall of about 50 

 feet into the valley, through which a very insignihcant stream at 

 present passes. 



On the op))Osite side of the valley about 100 yards wide at this 

 place, the escarpment is fully 75 feet high. About the middle of this 

 valley a slight elevation of solid rock some 15 feet high occurs. It- 

 occupies a jieculiar position and form, apjiearing as if strong currents 

 had worn away rock material, and left this irregular outlier, as a 

 monument of conditions no longer seen in this j)lace, where a mere 

 creek meanders through a well defined ravine. 



In this isolated area of rock on examination you find a most inter 

 esting and instructive series of Potholes, six in number, to .some ex- 

 tent in a line with the large one already referred to, as located about 

 150 yards to the N.E. 



A more unique series could scarcely be imagined. Calling that 

 already described as No. 1 , then here we have : — No. 2, 6 feet by 5 

 and 7 feet deep ; No. 3, 1 foot Vjy 1 and 3 feet deep ; No. 4, 6 feet
