notice the elevation of the flat itself. Where it leaves Flatwoods proper, 
it is somewhat below the 740-contour. The slope is gradually downward 
from this place to the south. Im the vicinity of Freeman the elevation 
of the flat is 700 feet. This makes a gentle slope down the valley southwest 
of a little less than ten feet to the mile. The Raccoon Creek addition ex 
tends up the creek almost as far east as the eastern margin of Flatwoods 
proper. ‘The old flat is recognizable for three and one-half miles up 
Little Raccoon Creek, which enters Raccoon Creek from the southeast near 
Freeman. The extent and shape of the addition can be seen by consulting 
the map. It contains in all about eight square miles. Thus this addition 
and the adjunct south of Stogsdill pond make an area approximating that 
of Flatwoods proper. 
While dealing with the Raccoon Creek addition of the Flatwoods 
basin, it must be emphasized that it occurs only in remnants. There are, 
however, quite large areas, sometimes a quarter-section or more, that have 
suffered little erosion. In such cases, or in cases where much smaller 
areas are preserved, there occurs the same flat, ash-colored, crawfish soil 
that is so characteristic of Flatwoods proper. Second to these flats, the 
most striking physiographic feature is the terraces resulting from the 
streams cutting down into the flat. The terraces begin almost immedi- 
ately after entering the gap from Flatwoods proper. Here they begin at 
zero, but soon become quite a distinct feature. They grow higher very 
rapidly, so to speak, as the stream cuts down into the flat to the south. 
At Freeman, four and one-half miles below the gap, the stream has cut 
down one hundred feet below the old flat, and the terraces are accord- 
ingly one hundred feet above the stream, 3ut in this vicinity there are 
many places where the terraces are indistinct, as they are so eroded that 
they no longer appear as terraces. This condition occurs in the immediate 
vicinity of Freeman. Beyond a slight bed-rock hill to the east of TFree- 
man, however, the flat is distinctly discernible, and the terraces show 
beautifully above the small tributary streams that are etching their way 
into it. 
UNDERGROUND INFERENCES AS REVEALED BY WELLS AND BORDERING REGIONS. 
Having dealt somewhat with the extent and topography of the Flat- 
woods region, we shall now turn to a slightly different phase. Perhaps 
the most interesting particulars of the region are the underground infer- 
ences as they are revealed by the wells of the region and by the places 
along the western margin, which have suffered erosion by the rapidly
