4. Light gray, rather hard fine grained sandstone 3 



5. Slope 20 



6. Fine grained sandstone, in thin layers, not well exposed apparently 2 



7. Slope, with occasional outcrops hard gray limestone 16 



8. Yellowish and dark gray laminated clay, or soft shale, with layers and 

 nodular concretions of argillaceous carbonate of iron, near base* 90 



9. Hard bluish argillaceous limestone, of which there was exposed in the 

 bed of a small stream, not more than 13 or 15 feet above the river, a thick- 

 ness of 1 



After passing this locality, we heard of a coal mine some three or four miles 

 south of here, near the base of an isolated hill, known as Shunganunga Mound. 

 We did not visit this mine, but were informed that it is considerably above the 

 summit of the last section, and that the bed is about 18 inches in thickness. 

 The coal is said to be of good quality. 



Above here on both sides of the Kansas, the country continues to be rather 

 low, no part of it being apparently more than two hundred feet above the river. 

 For a long distance above this, there is a beautiful broad, level bottom prairie, 

 on the nonh side of the Kansas, extending back from four to six miles, and as 

 much as eighteen or twenty miles along the river. Bounding this on the north, 

 the country rises by a gentle grassy slope to an elevation of from sixty to about 

 one hundred feet, furnishing the most beautiful sites for dwelling houses. 



For a considerable distance above the locality where the exposure near the 

 old Baptist Mission was examined, the hills especially near the river on the 

 south side, appear to be mainly composed of rather heavy deposits of laminated 

 clays and shales, with soft sandstones and occasional thin beds of limestone, 

 containing the usual fossils of the upper carboniferous series. At the crossing 

 of Mission creek, at an elevation of perhaps not more than twenty-five or 

 thirty feet above the Kansas, exposures were observed consisting first above of 

 five feet of light gray laminated clay, resting upon two or three feet of soft 

 yellow sandstone, which passes down into laminated arenaceous clays, of which 

 some eight or ten feet were exposed above the creek. 



Some fifteen or sixteen miles west of the point where the road crosses Mis- 

 sion creek, at a locality six or seven miles south of the Kansas, there is a high 

 elevation known by the name of Buffalo mound, rising as much as four hun- 

 dred and fifty or sixty feet above the river. At one place a large creek called 

 on the maps, Upper Mill creek, sweeps close along the northern base of this 

 elevation, and has carried away the loose debris so as to leave the lower strata 

 well exposed. The section here beginning at the summit of this hill is, 



Feet. 



1. A slope of about 160 feet, along the lower forty feet of which we 

 found loose specimens of Spirifer cameratus, S. planoconvexa, Eetzia Mor- 

 monii, Productus splendens? Chenctes Verneuiliana, C. mucronata, and Fusulina 

 cylindrica, var. veniricosa, with fragments of Chcetetes, Crinoids, c, of unde- 

 termined species 



2. Bluish gray limestone in two layers, the upper of which contains 

 columns of Crinoids, Productus Calhounianus, #c, while Myalina subquad- 

 rata, Orthisina Missouriensis, Allorisma, Pinna, Monolis, Sfc, of undetermined 

 species, occur in the lower 3 



3. Slope with no exposures of rock 96 



4. Rather hard mottled brown and light gray compact limestone, with 



a few Orinoid columns ; may be thicker, but only showing a thickness of.... 3 



5. Brown, whitish and green clays, with rugged white calcareous con- 

 cretions 4 



6. Fine argillaceous sandstone, with streaks of yellow and brown colors.. l 



7. Ash colored clay 10 



*There may be some thin beds of limestone in this portion of the section, as every 

 part of this ninety foot bed was not well exposed,
