of the Quapaw Nation, hard gray massive beds of the upper Boone 

 limestone are finely exposed in bluffs and benches known as the 

 Devil's Promenade. Along the east bank of the Neosho river, 

 south and southwest of Miami, the upper Boone limestone forms a 

 long outcrop ; the bed is composed of shaly, flaggy and lenticular 

 bedded limestone, some of which near the top and especially along 

 parting planes is decidedly arenaceous. Archimedes are abundant 

 in the upper part of these limestones. Along a little brook, one 

 mile to the west of Big Cabin creek, a full section of the limestone 

 overlying the Boone chert is exposed. The limestone bed is 

 about thirty feet thick and arenaceous throughout, though it varies 

 very much in the proportion of sand and lime in different strata. 

 The beds that are most arenaceous are shaly and lenticular and 

 some contain arenaceous limestone nodules with flinty centres. 

 Archimedes occur in some of these strata. East of Grand river, 

 opposite Chouteau, this bed is arenaceous and flaggy. About seven 

 miles east of Adair the Boone limestone outcrops along streams. 

 The rock is massive, hard, gray, fossiliferous limestone. The out- 

 crops seen northeast of Ft. Gibson, west and southwest of Tahle- 

 quah, are practically all gray limestone in rather massive strata. 

 The bed as it occurs along the Illinois river and Greenleaf creek 

 southeast of Greenleaf, is about thirty feet thick, mostly gray and 

 massive limestones. There is at the top of the bed, however, a 

 stratum of bluish limestone which weathers to a whitish color, and 

 the base of the bed is somewhat arenaceous, shaly and wavy. 



Along Walkingstick creek, about three miles north of Marble, 

 the stratum is thirty feet thick, and is composed of massive gray 

 limestone. The top of this bed, as seen in the base of a hill 

 one and a half miles south of the Tahlequah-Evansville road and 

 four or five miles east-southeast from VVauhillau, has a little blue 

 limestone that weathers white. Near the base it is decidedly 

 arenaceous and shaly ; the rest of the bed, which is the greater part 

 of it, is massive gray limestone as usual. East of Stillwell, south 

 and southwest of Westville, the stratum is from thirty to forty feet 

 thick, and is practically all gray limestone in layers from a few 

 inches to five or six feet in thickness.
