Chapter X: Introduction (1)

Certain conditions are to be taken into account in deciding whether a cave afforded a desirable permanent shelter to primitive man. It should be accessible; the floor should be dry, at least fairly level, and sufficiently free from large rocks to allow the inmates to move about freely; the entrance should be large enough to permit free passage and to light the interior to a distance that would insure protection from the elements. Temporary shelters or camping places might be deficient in some of these particulars and still be resorted to frequently; but if there were opportunity for choice, a man with intelligence to select a cave in which to live continually would, it is fair to assume, look for one possessing such features.

If such conditions, once established, were free from the mutations of time, the explorer would have but little difficulty in deciding upon a suitable site for his labors. But limestone, more than any other solid rock, is subject to constant erosion, crumbling, and falling; while the soil and loose fragments resulting from such action move downward year by year over the slopes and into any cavities where they can find their way. In the course of centuries the entire aspect of a cave may be so altered as to bear no resemblance whatever to its original appearance. Consequently a careful study must be made of the immediate surroundings, in order to determine what topographical changes may have occurred since the earliest time within which it is probable that man may have existed in that locality. Should the floor, at present, be of solid rock; or covered with only a slight layer of earth; or have a stream flowing over it; or show by marks upon the walls that it is subject to inundation either from adjacent streams or by surface water which finds its way in through sink holes; or be in such situation as to make it apparent that the original bottom was thus flooded in comparatively modern times, even though such may not now be the case--in any such event excavation would be labor wasted. On the other hand, all the necessary requirements for a convenient residence may now be present, and yet result from causes which have begun to operate within the historic period. In other words, there are very few cases in which the present appearance of a cave is to be deemed a certain or even an approximate indication of its actual state a few thousand years ago. There is only one way to determine whether extended excavations may possibly result in satisfactory returns, and that is to sink shafts or run trenches in the superficial deposits.

INDIANA

The cave region of this State extends from Owen and Morgan Counties to the Ohio River. The caverns and sink holes gradually increase in number and size toward the south, until they culminate in Wyandotte Cave, second only to Mammoth Cave of Kentucky in extent, and in the so-called "valleys" of Harrison County which are in reality nothing but sink holes several square miles in extent. Some of the caverns are described in detail by W.S. Blatchley, the State geologist, in the Twenty-first Annual Report of the Survey (1896). Very few of those mentioned by him are at all suitable for permanent occupancy, though several would afford excellent shelter except in the rainy season, at which time most of them have the floors muddy or perhaps covered with water for weeks in succession. Such as were visited in these explorations will now be taken up in their order.

LAWRENCE COUNTY

ROCK LEDGE QUARRY.--Early in 1903 periodicals mentioned an interesting discovery made at this place. According to the report, workmen in excavating a cut for a railway found an old cave entirely filled with stalagmite matter. In this, 10 feet below the former top of the cave--the cut did not extend to the bottom of the stalagmite--were discovered some bones which were pronounced by "several physicians" to be those of a human being. Among them was a "jaw tooth" (molar) and part of a skull. Correspondence failing to elicit any satisfactory information, a visit was made to the site. The cave could not be traced in either direction from the railway cut; but it had plainly served as an outlet for several large sink holes on the hill above it. Nothing could be learned here regarding the matter except that the objects had been found and were then in the museum of the State University at Bloomington. This place was next visited and the specimens inspected. There were many fragments still imbedded in the matrix, which was travertine rather than stalagmite. No exact determination of them had been made, but only casual inspection was needed to see that none of them could be human. The "jaw tooth" was from a peccary, the "human skull" was the carapace of a tortoise.

SHILOAH CAVE.--It was reported that, although the entrance to this cavern, 7 miles northwest of Bedford, was in a sink hole, the floor was level and accessible. The opening is almost at the bottom of the sink, whose slope is quite steep. After every rain the water runs in; and while the floor is level, as stated, it has a constant stream of water flowing over it and is in absolute darkness.

DONNEHUE'S CAVE.--Although water flows continuously from the entrance, the amount of discharge was said to be small and the cave floor level and covered with earth, while the cave itself was large and well lighted. The approach, however, is quite difficult; the earth is nowhere more than 2 or 3 feet thick, and after a heavy rain the stream extends from wall to wall.

Between Bedford and Donnehue's cave is one, unnamed, at the head of a ravine which was once an extension of the cavern. The opening is of fair size but the floor is of rock and the outflow of water is steady.

Just outside the corporate limits of Bedford, to the south, is an opening in the cliff at the head of a deep ravine, more in the nature of a rock house than of a cave. It would make an excellent shelter for a few persons, being accessible, protected from winds, and close to water. While it may have been so used formerly, the deposit of earth and stone on the floor is very scanty and anything beneath could well be quite modern.

Two caves were reported 2 miles south of Bedford. One is a small opening from which a stream issues, flows across a meadow, and enters the other cave, which is much larger. They are parts of one passage, the roof between these openings having broken down, and the stream is the same which finds its outlet at Donnehue's cave.

Several other caves in the vicinity of Bedford were visited. They are all small and of no importance from an archeological standpoint.

DONNELSON'S CAVE.--"The mouth of the cave is found at the head of a deep gorge worn through the limestone by a good-sized stream which flows from the cave and down the gorge to the broader valley beyond. Many centuries ago the cave extended the full length of the gorge, and the waters of the stream flowed directly from its mouth into the valley. The roof of the underground channel finally became so thin that it collapsed, the gorge was then started, and as the centuries went by grew in length, the cave becoming ever shorter by the continued falling of the roof.

"Three passages open directly into the mouth of the cave. The right hand passage has the level of its floor about 5 feet above that of the entrance, while the opening on the left is 12 feet above the level of the stream and very difficult to enter without a ladder. The middle passage extends straight back from the common vestibule or main entry. The latter is 25 feet long, 21 feet high, and 18 feet wide, but at its farther end is reduced to the narrow middle passage between great masses of limestone. The water in this passage is waist deep and explorations must be made by wading or in a light canoe. One hundred feet within is a magnificent cascade, where the stream rushes and leaps down a narrow passage with such violence that the noise is plainly heard at the entrance.

"The right-hand passage for the first 100 feet is about 10 feet high by 15 wide, with a clay bottom and a roof on a level with that of the vestibule. It then expands into a large room, 230 feet long and 40 feet wide, which lies east and west at right angles to the entering passage. This narrows at the west end to 20 feet, and at one point the outer air flows in through a small opening in the roof. From near the small end of the room a narrow passage starts off to the southward and can be traveled for 200 feet, when it becomes too small for further advance. Along this passage a small stream flows, disappearing through a hole in the floor near the entrance to the larger room. Other than this, both right and left passages leaving the main entry are dry.

"The passage at the left of the main entrance to the cave is about 150 feet long by 20 broad, and contains no points of especial interest." [W.S. Blatchley.]

It may be added to the above description that a heavy rain causes a rapid rise of several feet in the stream through the middle passage.

The cavern is situated 3½ miles east of Mitchell. It has been fitted up by the State University as an experiment station for the study of underground fauna and flora.

The branch to the right is never entirely dry. Throughout the year water trickles or seeps over the stones and keeps the mud soft and sloppy, while after extremely heavy rains the water may be 2 or 3 inches deep for a short time--enough to keep all the earth washed from the floor for 50 or 60 feet from the entrance.

The northern or left branch presented a smooth, solid floor of rock at the beginning. The roof is about 13 feet above the floor, being a flat stratum broken by a joint-seam along which there is a slight fault. A ledge of friable sandstone 3½ feet thick lies next below the roof. The disintegration of this gave a dry covering to the clayey earth which covered the floor almost to the extreme edge of the rock overhanging the stream and gradually rose toward the rear, where it entirely filled the space from floor to roof. The distance between the side walls is 8 feet at the mouth. They diverge slightly, and at 65 feet are about 12 feet apart. Here they separate more sharply, forming a chamber 30 feet in diameter, measuring on every side to the contact of the earth and the roof. At the extreme rear a slight wash or depression in the earth revealed the top of a vertical solid wall, thus marking the limit of the cave in that direction. It seems, however, to extend farther to the east and the west than it can now be followed; in fact, the indications are that at one time a considerable cross-cavern extended along this line.

The work of clearing out this branch began at the entrance. The superincumbent earth was removed by a trench whose boundary was the solid rock on each side until the cave widened to more than 8 feet between the walls; then a width of 7 to 9 feet was excavated midway between the sides, the entire trench having a length of 92 feet, or reaching nearly to the vertical wall at the rear. For about 60 feet the earth was removed to the rock floor. At this distance the floor dipped. The bottom of the trench continued to follow the same level it had held to this point, in the belief that the dip in the floor was due to a crevice or slight erosion channel and would soon disappear, bringing the rock to its normal position. This was not the case; several holes were dug, the deepest one 3 feet, into the mingled clay and rock, without finding any evidence of a solid bottom. The conclusion seemed certain that the passage leading from the entrance of the cave to the large room at its farther end was only a tributary or branch of a cross-cave extending in an east and west direction, as intimated above. Prof. Eigenmann, of the State university, reached the same conclusion through surveys not connected with this work. Under the circumstances further digging seemed useless; for if this should be a cross-cave the bottom would probably, almost certainly, be on a level with the stream now flowing through the central passage, while if it should prove to be only a cellar-like deepening, it would not be utilized for a habitation.

At 30 feet from the entrance the accumulated earth had a thickness of 6 feet; from there it rose gradually to the roof at the end.

At 37 feet, in a pocket of coarse sand on the rock floor, such as settles in a gentle current, were four fragments of bone. There is not enough of them to identify with certainty, but they seem to belong to a deer, a turkey, and some bird about the size of a quail.

At 66 feet in, a foot lower than the surface of the bedrock (being 5 or 6 feet beyond the above-mentioned dip), were small fragments or particles of charcoal, or what had every appearance of such. They were in earth that showed the lamination or stratification due to successive water deposits, and had been introduced in the same manner. The entire earth deposit below the sand capping showed this lamination, sometimes horizontal, sometimes curved, proving a long period of deposition. Further evidence of age is found in the travertine, 7 inches thick, that occurs on top of the earth at the back of the cave.

In the absence of all other evidence the specks of charcoal can not be accepted as proof of human life in the vicinity at the time these deposits were forming.

While the work was in progress three students from the university came through the central cave in a small boat, having entered through a sink hole 3 miles away in an air line. At some point of their course they lost their lanterns and made the remainder of the journey in absolute darkness, feeling their way along the walls, dragging or carrying the craft over shallows, and at one place lying flat in the bottom and propelling the boat by applying hands and feet to the roof, which was less than a foot above the water.

MARTIN COUNTY

Various caves are reported in the vicinity of Shoals. Those whose location was clearly given are merely "rock houses" or recesses in the Carboniferous conglomerate bluffs bordering the east fork of White River. Some of them would make fairly good shelters, but all which can now be examined are at so low a level that the river gets into them or very close to them in flood periods. Consequently there is no probability that ancient remains are to be found in them. Some of the shelters higher up on the cliffs may have been utilized, but the bottom of these is now covered with huge blocks, some weighing a hundred tons. It is true that such rock houses, in all parts of the country, were regular resorts for modern Indians, and they probably furnished shelter to the earliest inhabitants of this region, no matter how remote the period of occupation. But owing to their open front and the exposed situation of most of them, it is quite possible that the wind may remove the fine material falling from roof and sides almost as fast as it is deposited. At any rate the débris on the floors is seldom more than 3 or 4 feet deep, and articles very plainly of no great age are frequently found at all levels in it.

In a few places along the river bluffs limestone crops out beneath the sandstone, and springs occasionally appear along the line of junction, eroding small cavities, but these are subject to overflow, and none of them has an opening large enough to enter without crawling.

ORANGE COUNTY

VICINITY OF PAOLI.--From this town six caves were visited, all that could be located by diligent inquiry. None of them has any particular designation except "Mill Cave," which is so named because the stream issuing from it furnishes power for a flour mill. The water covers the floor at all seasons.

One, though quite small, could have been occupied at a former period, but the roof and front fell in some years ago, entirely closing it.

A third has a small entrance on a hillside. A steep and rough descent was followed beyond reach of daylight without coming to a level bottom.

The other three are very small with rock bottoms.

FRENCH LICK SPRINGS.--Two or three miles from this place is "Star Cavern," which is advertised as being of great size and beauty. The immediate surroundings are quite romantic and deserve the praise accorded the spot by visitors. The cave itself, however, more resembles an artificial tunnel than a natural result of 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 adjacent country over a territory of varying extent, sometimes many square miles. At some point the roof fell in more rapidly than in other parts, until at last it became so thin as to give way entirely. If the débris was not sufficient in amount to extend above that part of the roof which remained intact on either side, so that it would be gradually carried away, the cave would remain open in both directions, as is the case at the "Gulfs" just described and at other caves statements of which appear in subsequent pages. Usually the débris quite chokes up one side and all the superficial drainage is turned into the other, which is thus kept open. In time, the slope around the depression becomes tolerably uniform except close to the entrance, and there is no outward indication that the cave ever extended farther than the spot where the new entrance is located. So the cave, as it is now open to examination, is only a portion of the original passage, and as the explorer pursues his way, he may be going toward either the former mouth or the source. In the former case, he comes out of a large opening, or what was formerly such, on some slope in the neighborhood, or descends until his way is obstructed by water. In the latter, he may find his way shut off by diminishing passages, or he may descend to lower levels through newer drainage channels cut by the streams which have been reversed and forced to carve other outlets for themselves.

This change occurred in the Milltown Cave a very long time ago. Standing on the débris, several feet within the entrance and beneath a part of the roof now perfectly dry and showing no marks of percolating water, is a stalagmite 31 inches in diameter, which has weathered to a depth of 3 to 4 inches from atmospheric influences alone.

WYANDOTTE CAVE.--So much has been printed concerning this celebrated cavern that no mention need be made of its interior features. The place seems excellently adapted as a habitation for primitive people. It is situated on a hill at whose foot is the bank of Blue River. Five miles away, as the road runs, is the Ohio. The backwater sometimes reaches up the tributary for more than 10 miles. The flint-bearing stratum of the Harrison County aboriginal quarries outcrops a short distance away and appears at several points within the cave. The country is extremely rugged, and good springs occur frequently. Game was formerly abundant in the hills, and Blue River still rewards the angler with various species of fish, many of them of large size.

A former race, presumably the modern Indian, did much work within the cave. Tons of travertine or stalagmite, the so-called alabaster, have been quarried from some of the deposits, while a large number of flint nodules has been dug out of the cave-earth where they fell from the disintegrating limestone. Some of this labor was carried on more than a mile from daylight.

The mouth of the cave was formerly almost closed by a mass of talus. About 10 feet has been removed from the top of this, so that one may now walk in without difficulty. On the inner side of the portion remaining there is a slope for 96 feet, to a vertical depth of a little more than 27 feet. The next 100 feet gives a descent of about 3 feet; then another steep slope begins. The first point at which bedrock floor is found within the cave is 120 feet lower than the point of entry. It is supposed that the drainage to which the cave owes its origin was outward; if this was the case the floor must be more than 120 feet below the roof at the doorway. While this may be true, it is not indicated by the condition of the visible strata. For about 50 feet outward the side walls are nearly parallel and nowhere more than 30 feet apart. Then they terminate at an angle in the outcrop of the ledge along the hillside. The appearance and condition of the upper strata, together with this narrow separation of the side walls outside the cave, produce the impression that at a period not very remote the roof of the cavern reached to the outcropping ledge in which the walls end. Even though the rock floor should be at the great depth supposed there is a possibility that an earth floor could be found below the detritus which has accumulated since the roof fell in or has worn away.

To test the matter a shaft was begun at a point 16 feet in front of the doorway. This was as near as such work could be done without interfering with the advent of visitors, and allowed a margin of 30 feet toward the outer slope. The shaft, 6 feet in diameter, soon passed into a compact mass of red clay filled with rocks of various sizes. At 14 feet down this was broken by an irregular stratum averaging a foot in thickness, of coarse sand or fine gravel with a slight admixture of clay, such as would form in a running stream. Its slope was inward or toward the cave. As there are sandstone ledges on the hillside above, this sand may have come from them, but, if so, it is singular that none appeared elsewhere. At 18 feet down was a mass of travertine measuring nearly 3 feet across and from 6 to 12 inches thick. It had formed around the lower part of a stalagmite 18 inches long, and the bottom of the whole formation rested horizontally on clay. This gave the excavators hope that an earth floor had been reached, as the stalagmite was vertical and resembled in all respects stalagmites in the cave. But it was soon found to be a foreign inclusion, and the same confused mixture of clay and stone continued below as above. Various fragments of stalactites and stalagmites were found as part of the detritus. These, especially the vertical one, seem to confirm the supposition that the roof reached out this far at a period which is quite recent as compared with the age of the cave.

To a depth of 25 or 26 feet the task of excavating was as tedious and difficult as digging up a much-traveled, rocky road, the earth being dry enough to scour the shovels. Then the earth grew moist and within 2 feet was muddy. Cavities appeared, into some of which a switch could be thrust 3 or 4 feet. Where such a cavity extended under a large stone, stalactites were in process of formation. Soon the earth began to work into a soft mud under the feet of the workmen, and at 32 feet particles and small clods were noticed falling from the sides of the shaft. A foot lower this breaking away became more decided. It may have been due merely to the loose condition of the wet earth allowing unsupported portions to fall from the freshly exposed surface, but there was also the risk that the softer earth was sliding under the weight of that above. The workmen, two of whom were experienced well and cistern diggers, declared the risk too great and demanded to be brought to the surface.

The depth reached by this shaft was at least 5 feet lower than at any point inside, within 200 feet of the mouth of the cave. The material, with the exception of the sand layer, was almost identical from top to bottom, there being no apparent difference other than increase of moisture in the lower part. The only explanation suggesting itself at present is that the chasm is filled with large loose rocks up to a point near the bottom of the shaft; that débris from the hillside above has covered these more rapidly than it could settle in the crevices and cavities among them; and that water which makes its way downward finds some obstruction to its free passage out at the bottom of the chasm.

The only safe plan of excavation seems to require the removal of all the earth between the side walls to a depth below the mud. If the rock bottom, or any solid bottom, is at a depth of 120 feet, there is small chance that man lived in this region at a time when it was easily accessible.

SALTPETER CAVE.--This is about 600 yards northwest of Wyandotte Cave. "The entrance, in a side of a ravine, is 5 feet high and 19 feet wide. Once within, a gigantic room expands, 220 feet long, 75 feet wide, and 10 to 30 feet in height, with smooth flat ceiling and earthen floor, the latter descending and with its edges much encumbered with fallen rock." [W.S. Blatchley.]

From the description given, this would seem an ideal site for research. Unfortunately, the bottom of the ravine is not more than 5 feet lower than the top of the talus at the entrance. This slight elevation is the only barrier which keeps the surface water from flowing in, and while the ravine seldom has any water in it, there would be enough after a moderate rain to drown out the diggers who were working below its level if the bank were removed.

LITTLE WYANDOTTE.--This, like three caves on Blue River above Wyandotte, four in the vicinity of Leavenworth, and one on the opposite side of the river in Meade County, Ky., has a small entrance in solid rock, with a steep and narrow passage to the foot of a slope which does not expand into a room of any size until at some distance beyond daylight.

HARRISON COUNTY

The only cave of any note in Harrison County is at the King quarries, 5 miles east of Corydon. It has two outlets, one at the foot of a little cliff, through which a fine spring has an exit; the other in the face of the cliff, about 10 feet higher and a little to one side. The latter discharges more or less water after every rain. The drainage of several large sink holes is through the two openings. The owner says mud has accumulated to a depth of 3 feet on the floor within his remembrance, due to cultivation around the sink holes, which causes the soil to waste.

ILLINOIS

MONROE COUNTY

MAMMOTH CAVE.--The so-called "Mammoth Cave of Illinois" is near Burksville, in Monroe County. An opportunity was afforded to visit it while engaged in the cave work. It is very extensive, according to the owner's description, being "7 or 8 miles long." The mouth is at the bottom of a sink hole, and the cave is now reached by a narrow stairway 40 feet high. Formerly it was necessary to clamber down the walls, stepping from ledge to ledge with a foot and a hand on either side. Then a ladder was made, said to have been 50 feet long; and, with more frequent visitors, the stairway followed. The crevice is very short, a mere crack, apparently made by water working its way down from the bottom of the sink. All the drainage within the rim goes into the cave, and it accumulates in the rainy season until the floor is covered. A farmer living near says he has seen the water from the cave rise until it covered the bottom of the sink hole. As similar depressions are numerous in the vicinity, probably the combined inflow is greater than the cave can carry away. The floor has been leveled and a close pavement of large slabs laid over the muddy portions. No one has ever heard of human remains being found anywhere in the cave.

* * *

KENTUCKY

Crossing the Ohio River from the southern Indiana cave region, the counties of Kentucky lying in the belt of lower Carboniferous limestone were next visited. No cave that seemed worth examining could be heard of above the extreme southern portion of Hardin County. The sections examined will be taken in their geographical order from north to south.

HARDIN COUNTY

HUTCHINS OR BRADLEY CAVE.--This is in the bluff bordering on the left bank of Nolin River, 2 miles west of Upton. It was reported that human remains had been found in it. The present owners, who have known the cave for a long time, never heard of any such finds. The entrance is low and narrow, so that access to the cave is to be had only by creeping several yards. The cavern then expands into a very large chamber, separated into three by curtains or partitions of stalactites and stalagmites. Very little of floor, roof, or walls is to be seen, being almost entirely covered by secondary deposits. Some of these are remarkable for size and beauty. There is no probability that the cave was ever inhabited.

SALTPETER CAVE.--This is 3 miles southwest of Upton. It has a large entrance and an earth floor, but the dirt has all been worked over for making saltpeter, so there is nothing to search for.

HART COUNTY

LAIRD'S CAVE.--About 2 miles north of Northtown is a large, roomy cave, with a good entrance, but water drips from all parts of the ceiling, and the floor is muddy and rocky. The drainage from 3 or 4 acres of hillside flows over the arch of the entrance and logs 6 inches in diameter are carried into it by the surface floods.

LOCK'S CAVE.--This is a mile east of Rowlett's Station, near the top of a ridge, and lying nearly parallel with its crest. It affords another instance of a cave which has come to light only after a portion of its roof has fallen in. The detritus entirely conceals the opening at one end. The other end is entered by going down the fallen rocks over a slope of 15 or 20 feet, which leads to a bottom strewn with rocks. In such cases there can be nothing under the loose material, because the cave had no entrance until this had fallen in.

GARVIN CAVE.--This cavern, which is 3 miles southeast of Munfordville, has an opening at the bottom of a sink hole, requiring a rope or ladder for descent.

HARLOW CAVE.--This is 3½ miles southeast of Munfordville. It is a very large cave, apparently, as the slope down the débris is more than 40 feet high, to a rocky shelf, beyond which the descent was followed some yards without finding any indications that a level bottom was near. It is another illustration of the fallen roof.

WYNNE'S CAVE.--Three miles south of Rowlett's Station is a large sink hole. Stones thrown into the vertical shaft at the bottom can be heard striking the sides for three or four seconds before coming to rest.

WASH. ROWLETT CAVE.--On "the old Lewis Martin place," 1½ miles west of Rowlett's Station, a section of roof, 20 or 25 feet across, has dropped into a deep cavity. The sides are still insecure. The descent to a spring under what appears to be the original roof is somewhat more than 40 feet. The ceiling is not more than 6 feet high.

STEFFY'S CAVE.--Four miles southwest of Munfordville between 200 and 300 feet in length of the roof of a high and wide cave has fallen in. Ice remains in this cave until May or later every year.

JOEL BUCKNER'S CAVE.--About 10 miles northeast of Munfordville is a large cave with the entrance on a hillside. The roof has evidently extended several rods farther out than at present. The front part of the cavern is wide and high, but is now nearly filled with débris. The roof slopes at about the same angle as loose material within, there being not more than 3 feet of space between the two at any place nearer than 30 feet from the present mouth. Rocks thrown back showed the same uniformity of slope to continue at least several yards and the depth there to be about 20 feet below the top of the detritus at the mouth. This cave was suitable as a habitation before the material now choking the mouth had accumulated, provided water was obtainable. The nearest spring now is more than a mile away. An exploration would require, as a preliminary, the removal of several hundred cubic yards of compacted rocks and clay.

HARRY BUCKNER CAVE.--Half a mile north of the cavern last named is another with a very narrow entrance. The floor, which slopes downward, is solid rock in part, and the place is not adapted for occupancy.

CUB RUN CAVE.--Cub Run is a little settlement 12 miles west of Munfordville, near the Edmonson County line and about equidistant from Green River and Nolin River. Two miles in a direct line south of the village is a cave or rock shelter which has much local notoriety from the fact that three skeletons were found in it. They were imbedded in mixed ashes and earth and accompanied with several pestles, bone perforators, three flint knives, a small celt, and part of a clay pipe stem. One of the skeletons was that of a child not more than 8 or 10 years old. It has been pronounced the frame of a white child on account of the shape of the skull, but is more probably Indian, as the three were found together. Two of the bodies had been laid side by side; the other was near their feet at a right angle to them. In the back of the child's head is an incision somewhat over an inch long. The skull is slightly fractured downward from one end of this cut, and the corner or angle thus formed in the bone is pressed outward.

A flint implement found almost in contact with the skull fits closely into the aperture and may have produced it, as the form of the wound could have been thus caused.

The cavity or chamber of this cavern is about 100 feet across in each direction. There is a small opening near the back which has been examined to a distance of 75 or 80 feet, being there obstructed by large blocks of sandstone similar to those which fill the space from floor to ceiling along the back end of the shelter.

There is another very large block just at the entrance, in which are one shallow and two deep circular depressions which were probably mortars. Bones of deer, bear, and other animals have been found within a foot or two of the surface both outside and inside of the cave. Contrary to what is usual in sandstone cavities of this sort, the outside earth slopes upward from the entrance and after heavy rains considerable water flows into the cave. This makes the earth on the floor quite sticky at times, although it is mainly sand, containing very little clay.

The skeletons were found at a depth of about 16 inches, close to the side wall. A small trench dug where they were unearthed showed, in succession, a layer of ashes 4 or 5 inches thick and not more than 3 feet across, a foot below the surface of the floor; a few inches of earth; a layer of ashes an inch thick, at two feet; below this, yellowish undisturbed sand, apparently fallen from the sandstone roof, and continuing to the rock floor, which was about 32 inches below the top.

Another trench was dug about midway across the cave and the same distance from the front as the skeletons were found. This was on or close to the line of heaviest drainage into the cave and the earth was so wet as to be very sticky. A few little patches of what appeared to be ashes but which had not resulted from fires made on the spot, three or four broken mussel shells, and a chip of flint were found in the first 18 or 20 inches. More than this amount of earth could easily have washed in since they were left here by modern Indians. Below this level the earth contained not the slightest object of human origin, to the rock floor which was found at a depth of 6 feet. On the rock was nearly pure sand, probably the result of disintegration; some clay lay on this; then the mixed loam, sand, and clay composing the outside soil.

It would appear that this cave was utilized as a place of shelter at irregular intervals by Indians in tolerably recent times; that at least one of those found, perhaps all three, had died or been killed during a somewhat protracted sojourn; and that only a slight covering of earth, if any at all, had been placed over them.

Two similar caves are within 8 or 10 miles, but were not visited.

EDMONSON COUNTY

MAMMOTH CAVE.--For miles from the entrance saltpeter workers have dug down to a level where the amount of loose rock rendered further excavation too expensive. In many places walls of stone are piled against the sides of the cavern. They were among the earth that was removed and have been so piled to get them out of the way.

As far back as "Chief City," 3 miles from the mouth of the cave, the floor is littered with fragments of canes (reeds) and saplings, which, from the appearance of the ends, were broken, twisted, or bruised off with blunt tools like stone hatchets. Most of those remaining are lying on massive loose rocks now forming the floor, though the ends of some are seen projecting from beneath stones much larger than two men can lift. It is possible the latter have recently slid or slipped from higher up the slopes, but the indications are that they have dropped from the roof since the time of these early explorers. If this be the case, it points to a considerable antiquity for the remains, because no such downfalls are known to have occurred since the cave was first explored by white men.

So much work has been done about the entrance of late years for improving the approaches that excavation would be useless, even if allowed, unless carried to a depth of more than 20 feet. Such work would greatly interfere with the plans of the management.

WHITE'S CAVE.--This is about three-fourths of a mile from Mammoth Cave. The entrance, quite small, is near the crest of a ridge, and the floor descends abruptly. Only a narrow chamber exists within reach of daylight, and the cave is wet all the time a short distance back.

COLOSSAL CAVE.--It is said to be 4 miles from Mammoth Cave, but is really only a little more than 2 miles. The present entrance is entirely artificial, the descent to the floor being about 120 feet. The original entrance was in a crevice which explorers descended by means of ropes. It is said that another entrance is known to one man who, however, has to crawl a long distance.

SALT CAVE.--This is 4 miles from Mammoth Cave, though belonging to the same company. The entrance is at the bottom of a conical sink hole draining about an acre. Not much water runs into the cave from this cause, as the surface slopes outward from the margin except on one side, where a ridge leads to the hills. A spring which comes out near the top of the sink falls over a ledge at the bottom into the entrance to the cave. It is said that this water soaks into the ground within a few rods and that just beyond are large, dry rooms, well adapted for habitation, which formerly contained many evidences of aboriginal occupation. Exploration is impossible now, as the entrance was effectually closed some years ago by throwing in logs, brush, rocks, and earth, in order to protect the formations from relic hunters. The water from the spring falls directly on and flows into this, and can not now be turned aside. Even if it could, all excavated material would have to be carried up a steep slope and deposited in the field surrounding the sink hole.

DIXON'S CAVE.--It is supposed, with good reason, that this was at one time connected with Mammoth Cave. It can be easily entered, through a large crevice, where the surface rock has fallen in. Approach to the bottom is down a steep and rugged slope of about 60 feet vertically. Within, no earth is visible, it having been entirely removed by saltpeter miners, who left the rocks piled in great rows from side to side across the cavern.

MAMMAL CAVE.--This is so named because a tusk was formerly exhibited at the hotel which was reported to have come from here. It was afterwards learned that the specimen was imported from another State. The cave is small and damp, not suitable for living or even for stopping in.

PROCTOR'S CAVE.--This is 6 miles from Mammoth Cave. The present entrance is artificial and so far as could be learned the cave is a recent discovery.

HAUNTED CAVE.--The name is given to commemorate the fact that human bones were found in it. Physicians, it is said, pronounced them bones of a white person. The cave, which is on Green River, some miles below Mammoth Cave, was not visited, as the entrance is described as a crevice through which a man has difficulty in squeezing his way, while the interior is nowhere more than 8 feet wide. The cave soon connects with another narrow vertical crevice which reaches the surface at the top of a ridge.

BRIGGS'S CAVE.--About 6 miles west of Cave City, and 4 miles west of north from Glasgow Junction, is a cave on land of Ike Briggs, which was described as fit for habitation. Its entrance is in a small sink hole, on a hillside. The approach is easy, and entry not difficult; but the cave receives the drainage of several acres and the floor is always muddy.

POYNER'S CAVE.--This is a mile east of Briggs's. While a large cave, the entrance is at the foot of a sink hole an acre in area. It is necessary to stoop for some distance on entering, and the bottom here is rough and wet. Farther in it is dry and roomy--so much so, that people in the neighborhood use one chamber as a "ballroom." This part is some distance beyond daylight. As in all caves which are entered from a sink, it would be very difficult to dispose of any excavated earth, as it would have to be carried up the steep slope to the outside.

SHORT CAVE.--Chaumont is a station on the road to Mammoth Cave, 3 miles from the Glasgow Junction. The cavern, which is so named from its limited extent as compared with Mammoth, is a mile from the station. The entrance, reached by a winding way along the ridges, is on one side of an irregular depression comprising 3 or 4 acres. At present there is a heavy bank of earth, several feet high, across the entrance, nearly closing it to the top, except at the middle where a wagon road has been cut through to allow fertilizers for mushroom beds to be hauled in. This earth, so it is stated, was not there when the cave was discovered, but has been carried from the interior partly by saltpeter workers, and partly by the present owner in order to cover up some rocks and to make the floor smooth and level. In front of the cave and of the earth piled at the entrance is a level space of 25 or 30 feet to a deep sink hole. Some water and mud, in time of wet weather, runs into the front part of the cave but its effect is not noticeable for more than 30 or 40 feet. Beyond this is a reach of more than 200 feet of perfectly dry level floor. It was not so smooth before some grading was done for the mushroom beds, but was at no time rugged or difficult to travel over. At 300 feet from the entrance is a slope about 20 feet high, at the foot of which begins another floor so dry as to be dusty in places. Whether this apparent thickness of 20 feet is of earth, or earth and stone mixed, or is indicative of a dip in the rock floor, is not known, as no excavation has ever been made except for the plant beds. There is a slight descent, not more than 3 or 4 feet, from the entrance to the point where the flood water seems to reach. This is seemingly due altogether to the wash. The width of the cave is about 50 feet, and notwithstanding the partial closure of the entrance there is sufficient light as far back as 200 feet to enable one to read ordinary print. So there is ample room within reach of daylight for several hundred people to gather without inconvenience.

The owner, Capt. J.B. Briggs, who lives in Russellville, has granted permission to make any excavations desired, provided the floor be left in good shape when done. It is evident that any satisfactory examination will demand a large expenditure. If only a preliminary trench were made, the necessary slope would require a considerable width at top, while if anything should be disclosed that called for extensive research, the earth must be wheeled or otherwise removed to the sink hole in front, and the whole floor brought to a nearly uniform level.

So far as appearances go, this cavern is better adapted for occupancy than any other which has been examined. The depth of earth shows it to have been open for a long period. If nothing can be found here, denoting extreme antiquity of man, it would seem useless to make further search in central or western Kentucky.

BEAR CREEK.--A very large rock house is on the right bank of Bear Creek, 3 miles above its mouth. It would afford good shelter to a large number of people, except in rainy seasons when they were most in need of it. After heavy storms the creek covers the entire floor.

Other rock-shelters exist along Green River above and below Bear Creek. They are not worth investigating. Some are flooded; others difficult of access; still others become muddy after rains; while in none of them is there any great depth of earth.

WARREN COUNTY

CRUMP'S CAVE.--A mile north of Smith's Grove is a large sink hole, from one side of which extends a cave nearly a mile long. There is abundant room and a good light near the front, and it is reported that quantities of ashes were formerly to be seen on the earth a short distance in. A considerable outside area drains into the cave, and the floor at the present time is everywhere so wet as to be quite muddy. Much water also falls from the roof. A hydraulic ram, not far from the entrance, formerly forced water from one of these falls to the farm residence. A descent of 6 feet, over large rocks and wet earth, brings one to the nearly level floor, 40 feet from the mouth. The amount of flood water running into the cave is indicated by a gully 4 feet deep and the same in width, while trash and driftwood litter the floor from wall to wall for more than a hundred yards.

THOMAS CAVE.--This is a mile north of Bowling Green. The roof of a cavern has fallen in and forms a high mound of rocky débris, down which a path winds on each side, giving access toward either end of the cavern. There is scarcely a possibility that it was ever occupied.

MILL CAVE.--Three miles south of Bowling Green a stream emerges from the foot of a slope, flows a hundred yards through a canyon-like open channel, and disappears under a cliff. This is another instance of an open cave due to a falling roof. The open end is large and forms an excellent shelter for cattle. On either side of the stream, under the cliff, is a shelf or projecting ledge, covered with loose stones. Neither is 2 feet higher than the water level in a wet season.

BARREN COUNTY

PAYNE CAVE.--This, also known as Saltpeter Cave, is near Temple Hill, 9 miles southeast of Glasgow. The bluff in which it is situated is a conglomerate limestone, rising from the waters of Skagg's Creek. The cave has three different entrances, 100 feet or more apart, and each entrance is broken into three or four by columns or masses of stone that have resisted erosion. None of the entrances is large, or opens into spacious chambers within daylight. Flood marks are visible in all, and it is said that after prolonged or heavy spring rains the water covers the floors.

BEN SMITH'S CAVE.--This was discovered while digging out a fox den. It is a tunnel-like cavity, not more than 6 feet high or wide, and not suitable for habitation. It lies a mile and a half south of Temple Hill.
