couple of hundred yards north of the crossing of the old Malvern- 

 Murfreesboro road. The upper beds of the novaculite appear at the 

 surface, but in a very small exposure. The structure appears to be 

 an overturn. In 5 S., 20 W,, section 6, on Big Hill creek, dips in the 

 shale suggest that this overturn crosses the creek a little north of the 

 half mile line. In 5 S., 21 W., section 4, on the Valley Fork of 

 Point Cedar creek, half a mile north of Valley post-office, a seventy- 

 five foot ridge is cut by the stream, exposing novaculite in thin 

 ledges for a total thickness of 100 feet. The dip is perpendicular, 

 indicating an overturn of the type G'H', Fig. 14. The connection 

 between this and the first exposure is doubtful, but having the same 

 structure, and being in the same strike, it may be assumed that they 

 are the same. West of the exposure on Valley Fork, the overturn 

 can be traced into an anticline which is crossed by a branch of 

 Point Cedar creek in 5 S., 21 W., section 7, northeast quarter. 

 The strike from Valley Fork west is a little south of west. No 

 trace of it was found further west, unless a small anticline on Cox's 

 creek in 5 S., 22 W., section 9, southwest quarter be a continuation 

 of it. 



Minor Anticlines. — A small anticline is crossed by the Arkadel- 

 phia-Hot Springs road in 5 S., 20 W., in the south half of section i ; 

 and another in 5 S., 20 W., north half of section 9, by De Roche 

 creek. 



BayoiL Delile Overturn. — The Bayon Delile in its upper course 

 runs east for some distance along the foot of a 75 or 100 foot ridge, 

 finally turns south and cuts through the ridge in 5 S., 18 W., ex- 

 posing an overturn in the gap with its overthrow to the south. This 

 overturn shows again in perpendicular dips in 5 S., 19 W., section 

 15. It appears again to the south in 5 S., 20 W., just south of the 

 northeast corner of section 16, on De Roche creek. It has not 

 been found further west. 



Minor Anticlines. — In 5 S., 20 W., section 16, close to the south- 

 west corner, on a small branch of De Roche creek, is a small anti- 

 cline, and again in 5 S., 21 W., section 13, is another or possibly 

 a continuation of the first. In section 26, on the Caddo an anti- 

 cline with a southwest strike shows very nicely. In 5 S., 22 W., 

 southeast quarter of section 17 and southwest quarter of section 16, 

 near the south section line, anticlines are exposed on Cox's creek. 

 Also in the southeast quarter of section 15 a small anticline is ex- 

 posed on a tributary of Cox's creek.
