f erosion. The
floor is clean rock with a little brook flowing over it.

Two other caves not far from Star Cave are dry, but with solid rock
floors, so they were not visited.

ORANGEVILLE.--Near this place are the so-called Gulfs of Lost River.
The stream sinks a few miles east of Orleans, emerges at the "Gulfs"
from one side of a very large sink hole with precipitous margin, and
immediately goes out of sight again in a deep pool or chasm. It
reappears a mile or so away at the foot of a cliff where, after heavy
rains, it boils up like a gigantic fountain. Numerous small caves or
sink holes exist in the neighborhood, three of which were reported as
being dry, lighted, having good entrances, and well suited for
habitancy. One of them is at the bottom of a sink hole on a hill. The
descent is steep and rocky for 20 feet (it was not followed farther)
and no doubt so continues to the level of the river which flows almost
directly under it.

The two others are in the principal "Gulf." They are open and of good
size, but mud high on the walls shows they are filled with water in
wet seasons.

CRAWFORD COUNTY

MARENGO CAVE.--This is growing famous as it becomes better known.
Blatchley says that in it "are probably crowded more beautiful
formations of crystalline limestone than in any other known cave of
similar size in the United States." Visitors who have been in both say
it surpasses Luray Cavern in the magnificence of its sheets and
columns of deposited material.

As it was not opened until 1883, and the bottom can be reached only by
a stairway 60 feet high, it was of course unknown to the aborigines.

A small cave near Marengo has an opening on a hillside, and can be
directly entered from the outside; but it is at times a passageway for
a strong current of water 3 feet deep and extending the full width of
the cavity.

MILLTOWN.--A mile north of the town is a large cave which would
furnish an abode for scores of people. The entrance is in a slight
depression on the level upland west of Blue River. The descent is down
an easy slope of fallen rock and earth about 30 feet deep to a rock
floor. Beyond the foot of the slope there is a slight thickness of
earth, so that explorations could reveal nothing that had a certainty
of antiquity.

There is presented here a fine example of the manner in which caves of
this character become exposed to the upper world. At first, there was
an underground channel draining the adjac
