Description . 



2 — 1' calcareous sandstone, contain- 

 ing Pecten and Myalina. 

 3—10' shales, 

 (li miles above Brush Creek, on Mo. 

 bluffs, is 16' of sandstone, and Nos. 125 

 & 126 not seen.) 



Ashy limestone, containing Bryozoa, 

 Orthisina umbraculum, &.c. 



Ashy-green argillaceous shales. 



Ochreous brown and decomposing lime- 

 stone. 



Gray limestone, sometimes reddish or 

 fleshy gray, with specks of pellucid 

 calc spar disseminated, in tolerably 

 even beds; at top is found Fusulina 

 cylindrical, Archceocidaris and Crinoid 

 stems ; springs abound at the base. 



Blue and bituminous shales. 



Argillaceous shales. 



Blue limestone, even-bedded, fine-grain- 

 ed ; abounds in Productus Rogersii and 

 Pr. (c.quicostatus ; has also Orthis kemi- 

 plicata, Spirigera, Or. Missouriensis, 

 Or. umbraculum, and Spirigera subti- 

 hta. 

 The upper 1' is sandy shales ; below it, 

 we have at Weston 10' of hard blue, 

 slightly calcareous, ripple-marked sand- 

 stone, which is often replaced by a san- 

 dy shale; lower part, sandy shales. At 

 some places this bed almost thins out; 

 at other places it is thicker. 

 13' to 23' of limestone, distinguished in 

 Note Book by the name of "Plattsburg 

 limestone." Near Farley it is 13' thick, 

 and becomes thicker as we descend the 

 river. Near Farley it is coarse gray 

 and ashy-blue. In the eastern part of 

 Platte and in Clay Co. we generally 

 find at top from 2' to 3' of buff lime- 

 stone, having a pot-metal ring ; below, 

 it generally appears thus : 

 1 — 8' dark ash limestone; it weathers 

 brown ; contains Pr. costatus, Pr. 

 aipiicostatus, Bryozoa, &c. 

 2 — 2' coarse gray and minutely cherty 



limestone. 

 3 — 6 ' bluish-gray limestone, with numer- 

 ous remains of fossils, leaving 

 lines of calc spar. 

 4 — 2' irregularly bedded blue limestone ; 

 wcittiers brown ; contains chert, 

 Pr. costatus, P. Rogersii, Sp. ca- 

 rneratus. 

 5—2' soft decomposing brown limestone.
