the supply of remains was by any means exhausted. Little 
systematic search was ever undertaken at any other salt-licks of 
Kentucky for these remains, though desultory digging revealed 
their presence in notable numbers. 
Caves also came in for a large share of attention in the early 
days as repositories for these remains. Discovery here was mainly 
the result of the development of the saltpeter industry. In ex¬ 
ploring some of these caves for the nitrous earths Dr. Samuel 
Brown, of Lexington, came into possession of an extinct peccary; 
and Mr. John Clifford, also of Lexington, obtained the skeleton 
of a Megalonyx. 
About the year 1813 there was found, either in the Mammoth 
Cave, or one of the nearby caverns, a human mummy, which at 
the time excited considerable notice. Accompanied by a drawing 
executed by C. S. Rafinesque, it was minutely described in volume 
eighteen of the Medical Repository for the year 1814. Also, 
about the same time, there were obtained in the Mammoth Cave 
and neighboring caverns, all as the result of excavations for 
nitrous earths, a variety of articles of aboriginal manufacture. 
During the past few years exploratory interest revived; and 
there was undertaken in the vicinity of Lexington the exploitation 
of two new caves which had been discovered a short time before. 
Although as yet only the surficial layers in each cave have been 
examined a considerable variety of bones were obtained. A newly 
discovered extension of the Phelp Cave yielded the remains of a 
bear. In another, the Smith Cave, occurred the remains of a rac¬ 
coon, a ground-hog, a fox, various rodents, a large wolf, deer, a 
bear (believed to be the polar species), and a buffalo. Human 
bones also occurred plentifully. 
Preliminary investigation of various other caverns and rock- 
shelters in different parts of the State also resulted in the finding 
in nearly every instance skeletal and implemental remains of man. 
In these caverns, rock houses and salt-licks of the lower Ohio 
Valley there must surely exist much interesting paleontological 
and archeological material awaiting only systematic exploration. 
Much of this material undoubtedly accummulated at that remote 
time when the margin of the continental ice-sheet was not so very 
far away. If man existed in this country during Glacial times 
it is here in these caverns and rock shelters and around the salt¬ 
licks that abundant evidences of him should be sought.
