College of Ohio, is, however, of the opinion, that on it was placed a
dead body,--similar contrivances being used by some Indian tribes on
which to place their dead. Although thousands have passed the spot,
still this was never seen until the fall of 1841. Ages have doubtless
rolled by since this was placed here, and yet it is perfectly sound;
even the bark which confines the transverse pieces shows no marks of
decay.

We passed through some Side Cuts, as they are called. These are caves
opening on the sides of the avenues; and after running for some
distance, entering them again. Some of them exceed half a mile in
length; but most generally they are short. In many of them, "quartz,
calcedony, red ochre, gypsum, and salts are found." The walking, in
this part of the avenue, being rough, we progressed but slowly, until
we reached the Salts Room; here we found the walls and ceiling covered
with salts hanging in crystals. The least agitation of the air causing
flakes of the crystals to fall like snow. In the Salts Room are the
Indian houses, under the rocks--small spaces or rooms completely
covered--some of which contain ashes and cane partly burnt. The
_Cross Rooms_, which we next come to, is a grand section of this
avenue; the ceiling has an unbroken span of one hundred and seventy
feet, without a column to support it! The mouths of two caves are seen
from this point, neither of which we visited, and much to our loss, as
will appear from the following extract from the "Notes on the Mammoth
Cave, by E.F. Lee, Esq., Civil Engineer," in relation to one of
them--the Black Chambers:

resembling the walls, pedestals, cornices, etc., of some old castle,
