" At the outward angle formed by this cave with the preced- 

 ing one, is to be seen a nearly circular aperture of about a foot 

 and a half in diameter, which leads to a cavern yet unexplored, 

 the extent whereof is not known with any certainty ; but con- 

 jecture and supposition will have it to extend two arpents — an 

 astonishing distance as a natural subterraneous passage. Sura- 

 mins; the leno^ths of the several caves above-mentioned too*ether, 

 we have a total distance of a hundred and ninety-five feet of sub- 

 terraneity in the solid rock offering a beautiful rock of crystallized 

 sulphurate of lime, carved as it were by the hand of art, and exhi- 

 biting at once the sublimity of nature, and the mastery of the all- 

 powerful Architect of the universe." 



From the foregoing description there would seem to be five 

 diflPerent caverns or galleries, and probably many more, if the 

 fifth has been since explored. Three of them branch off from the 

 entrance in different directions, whilst the remaining two do so at 

 the termination of the central gallery. The roof throughout is 

 covered with stalactites, but as no mention is made of stalagmite, 

 nor of the presence of bones, we are left to conclude that they 

 were absent, although the chances were much in favor of find- 

 ing the latter, in consequence of there being a free and un- 

 obstructed entrance into the cavern.

 "The attention, not of geologists only, but of men of science in 

 several departments, has, during this and the preceding year, been 

 fully awakened to the importance of a discovery which is really of 

 much older date — viz., that flint implements, the work of man, are 

 found in beds of drift gravel associated with the bones of the last 

 generation of the great extinct mammalia. The full significance 

 of this fact is only now being fully recognized, and many of the con- 

 clusions which it may tend to establish are subject to much doubt,
