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 

 u 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 

 bigher 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- 

 sor. The old tributary extended nearly two miles eastward. Practically 

 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 </ld
