west of the road. Now, it is at the very road ditch, and immediately 
descends twenty-five feet. If nothing should interfere with it, it would in 
ut Short time destroy the road here by etching into it. 
There is no doubt in the mind of the writer that McBrides Creek at 
one time extended eastward to the very divide between the adjunct basin 
and Raccoon Creek, but evidence shows that probably most of the water 
that fell into its upper portion was carried by underground drainage 
either to the lower part of the stream or to the east and to the south to 
Raccoon Creek. At present practically all the water falling into the adjunct 
basin goes into Raccoon Creek, mainly through the sinks at the southeast 
corner of the adjunct region. Two very large springs come out about a 
mile south of where the water enters these sinks, which in all probability 
are outlets of underground channels beginning at the sinks in section 11. 
The Raccoon Creek addition of Flatwoods may be treated in a few 
words. This region was the site of an old stream which followed the same 
valley that the present stream does. The present stream, as stated before, 
has cut itself down into the old flat and in some places has removed much 
of the filled-in material. Raccoon Creek, however, does not reach bed-rock 
until it is at least 100 feet below the old flat, as found in the southern part 
of section 26. Yet there is a short distance that the stream passes over 
rock in a rather constricted place in the middle northeast part of the same 
section. This portion of the stream has evidently been cut since the time 
that the old valley was filled. The old stream evidently passed to the east 
of this place, as indicated on the map. 
The faces of the terraces have but few portions that show the material 
of the terraces, but the few that are shown, and the rock structure of the 
higher areas, along with the sinks in the terrace flat, reveal the ancient 
drainage lines in a very able manner. The small tributary entering Rac- 
coon Creek just north of the mouth of Little Raccoon Creek once extended 
nearly three-fourths of a mile farther east than it does now. It is making 
heroic efforts to recapture its old drainage basin: it is being aided by 
underground drainage, much material having been carried away leaving 
great sinks in the one-time flat. A small tributary no more than one- 
fourth mile long enters Raccoon Creek from the east in the middle of sec- 
tion 23. This tributary is a very small one in comparison to its predeces- 
cor. The old tributary extended nearly two miles eastward. Practica'ly 
all of this region is now drained by sinks, which have caused the old flat 
to be considerably depressed locally. Well No. 24 is near the site of this old
