244 ASHLEY — GEOLOGY OF ARKANSAS. [May 13, 



was also found at this point a fragment of a larger stem showing 

 leaf scars. The original material of the specimen has been car- 

 bonized. The specimen was not identified. Small round stems 

 are also found at this place, but though showing some structure un- 

 der the microscope, they were not identified. This and the next 

 were the only localities found which promise fossils of value on 

 further exploration. 



Bluff Mountain Locality. — Sparsely scattered through the shale 

 and sandstones forming the northern part of the bluff on the west 

 side of Antoine creek at Bluff mountain in 7 S., 23 W., section 34, 

 were found many fragments of stems similar to those mentioned 

 above. 



Suck Creek Locality. — The same kind of stems were also found 

 in a loose block, well up on the north bank of Suck creek in 7 S., 

 23 W., section 30, at the bend where the creek changes from an 

 east to a south course. 



Chalybeate Mountain Locality. — Where the Caddo Gap road 

 crosses the Chalybeate mountain in 7 S., 24 W., section i, the 

 rocks exposed in working the road near the top show traces of plant 

 life, but nothing was found that could be identified. 



Little Missouri Locality near Mu7'freesboro. — On the Little Mis- 

 souri river in 8 S., 25 W., section 6, a few of the stems common to 

 this region were found in an argillaceous sandstone. 



Little Missouri Locality near Pine Mountain. — Plant fragments 

 like those mentioned above were also found on the Little Missouri 

 in 5 S., 27 W., section 23, in the shales in the bend of the river 

 half a mile north of where Pine mountain strikes the river. 



Little Missouri Locality near Gap. — A short distance south of 

 the Gap in 5 S., 27 W., section 5, at the south end of the layers 

 of shaly sandstone, the shale or sandstone is full of carbonaceous 

 streaks and patches, which prove to be remains of stems of plants 

 very poorly preserved. The impression of a stem with a thorn 

 was found at this point. The stratigraphic position of this locality 

 is shown on PI. i, Sec. iv, the specimens are from the top of the 

 arenaceous shale just below the grit shown, and only about 300 feet 

 above the black novaculite and shale. 



Star-of'the- West Locality. — On the south bank of the creek (just 

 south of Star-of-the-West), at the foot of the hill, was found a sec- 

 tion of a stem an inch and a half in diameter which is probably 

 a Calamites. This was found loose on the hillside and probably 

 came from the shales which form the bank at this point.
