the outflow
from a large spring located at the foot of the hill, a fourth of a
mile to the southward, which boils up in a pool 40 feet across and at
its lowest stage discharges several thousand gallons every hour. Its
volume responds quickly to a heavy rainfall and to the succeeding
period of fair weather, although its level never passes above or below
certain fixed points. A singular feature of this spring, one which has
given it a wide reputation, is its rhythmic ebb and flow. With
absolute regularity, regardless of atmospheric conditions, it swells
for six hours, then subsides for an equal period, stages of high and
low water occurring at the same hours every day. The extreme range of
level is about a foot. Intermittent springs are not uncommon; but the
regularity of this one is remarkable, particularly so as its action is
not affected by changes in the volume. A dam was built below this
spring by the father of Mr. Miller to furnish power for a mill; when
the mill was not running the noise of the falling water, reenforced by
the echoes from the hills around, could be heard a long distance and
gave it the title of Roaring Spring. The Indians had a name for it
which was interpreted by the whites as "Blowing Spring;" but as there
are no unusual currents of air in the vicinity it is probable the
proper translation would be "Breathing Spring," on account of its
recurrent motion. The branch from this spring, following a course
along the foot of the hill, is wide and shallow, though swift, and is
nearly filled with a dense growth of long, moss-like vegetation which
was greedily devoured by deer, herds of them being frequently seen in
the water by early settlers.

From the mouth of the cave several hundred acres of fertile alluvial
land can be seen along both banks of the river. In the bottom land
lying nearest to the spring branch--which is itself entitled to be
called a creek--and extending southward to Miller's residence, partly
on an upper terrace, but mostly on the low land, was a village site on
which were formerly many small mounds which from the description were
undoubtedly house mounds. Mortars occur in numbers, while fragments of
pottery and flint, as well as many unbroken implements, were formerly
abundant to a depth of several inches. On the opposite side from the
cavern, in the angle formed by the abrupt turn of the river, is
another village site. A ditch, with an interior embankment about 6
feet high, formerl
