field, on tlie same farm, is a shelter cave under a bluff of subcarboniferous sandstone. The roof and wall in places still show the effects of heat and smoke. Many chips are in, or on, the dust of the floor; and it is said that when the site was first known one could not see the ground for the flint." There is a good, never-failing spring at one end of the cave, and the hogs have resorted to the spot ever since the country was settled. The mud they have carried in, added to the sand falling from the roof, has filled the floor to a much higher level than it formerly had.
On Borden's farm, a mile directly east of Leavenworth, much flint occurs in strata or laminae of varying thickness, from a small fraction of an inch up to 6 inches; occasionally it will increase, in a fiattened nodular form, to 10 or 12 inches. It weathers out of the limestone in angular fragments which shatter under a blow, consequently was not sought for arrow making. It has a vertical range of 25 or 30 feet. At only one place is there any evidence of work; where a seam crops out in a ravine the flint has been hammered off to a slight extent; and on a little knoll near by are a few spalls and chips.
Opposite Leavenworth, on the Kentucky side of the river, a few nodules occur in the limestone; but they are of different character from the nodules used so abundantly, and do not corne out of the matrix entire, shattering from effects of weathering.
A small amount of flint occurs in the limestone at the mouth of Potato Run, 2% miles above Leavenworth; the same remarks apply as to the last mentioned.
There is a small workshop on the river bank at the mouth of Potato Run; chips are abundant over one-fourth of an acre, though none of them seem to be of the flint found near by. There is another workshop on the right bank of Big Blue River, about 300 yards above its mouth; flakes show abundantly when the ground is plowed.
In all the river bottoms, and especially on the shores where the banks have caved in and the earth washed away, for several miles up and down the river from Leavenworth, flint chippings are very plentiful.
WYANDOTTE CAVE
Much flint, both stratified and nodular, is found in Wyandotte Cave. Owing to pressure of the rock above it, the former fractures naturally at right angles to the stratification, the fragments varying from small thin flakes to pieces as large as a brick. Most of it is about 3 inches thick and its form of fracture gave rise to the belief, so often published, that the Indians dressed it into blocks
