-38              MAMMOTH CAVE.

a part of the Mammoth Cave, yet there is no direct
comrnunication between the two.
  It is remarkable for the beauty and variety of the
stalactites and stalagmites that are found in it, and
is well worth exploring.
  White's Cave is about five hundred yards in length
           CONCLUDING REMARKS.
  There are about one hundred and fifty avenues in
the Mammoth Cave that have been explored, many of
which, however, are never entered by visitors, and
which, consequently, we have not attempted to de-
scribe. The total length of all the avenues has been
estimated at one hundred miles, which probably falls
far short of the actual distance. It must not be sup-
posed, however, that the Cave has been fully explored,
for there are hundreds of avenues that have never
been entered, much loss explored, many of which, we
have every reason to suppose, are as large as any
have been examined.
