Half a mile west of Dillon a ravine heads at the Frisco track, goes south a short distance, then turns southeastward. Near the track begins a group of mounds which reach for fully a mile along both sides of the little stream.
There are more than 100, most of them small, though at least one is 60 feet across and 3 feet high.
At the northern border of St. James is a small shallow valley with a northern and eastern trend, practically parallel with the Frisco Railway, and for 3 miles or more not over a fourth of a mile from it at any point.
Starting near the Soldiers' Home is a group of mounds which extend for fully 2½ miles down both sides of the valley.
Some are partly cut away by the stream, others are on the narrow flat bottoms subject to overflow with every hard rain, still others are built on the slopes to an elevation of 40 feet. They are somewhat larger than the average, a diameter of about 60 feet and a height of 3 feet being not uncommon.
A cave on the McWilliams farm, near Jack Hinshaw's, at the upper end of the Big Eddy, near the south line of Pulaski County, has an entrance 8 feet high and 15 feet wide. There is a good light for 150 feet, at which distance the cavern turns. It is an excellent location for an Indian home, having a floor of dry earth, and a small amount of refuse was found; but the earth has been thoroughly dug over in the search for missing residents, some human bones rooted out by hogs having given rise to a belief that these may have been murdered and concealed here.
Facing Roubidoux Creek, on the farm of J.W. Davis, 3 miles north of Cookville, are three caves. The largest is 40 or 50 feet above the foot of the bluff. It has an entrance 30 feet wide, the roof being 8 feet high. It is well lighted to a depth of 120 feet, where it curves. No refuse was observed, but the situation is favorable for habitation.
Another cave, near this, has an entrance 30 feet wide and 10 feet high; it is well lighted for 40 feet back.
The third cave of this series is a rock shelter a short distance south of the second, and higher up in the bluff.
All these appear to deserve an examination.
A cave on George Berry's land, in a ravine opening into the east side of Roubidoux Creek, 3 miles from Hanna post office, has a small entrance which is nearly closed by "drip rock," the roof, walls, and floor being thickly incrusted. These deposits, which it is said are even more abundant farther in, seem to be rather rapidly increasing in volume.
