which "agrees exactly, so far as they go, with that of division 

 B of the section [its lower part] at the landing, with the excep- 

 tion of Fusulifia."^ Since the time of ' Meek's exploration, the 

 construction of the B. & M. R. R. R. along the river bluff below 

 the old steamboat landing has exposed the rocks and shown 

 Meek's supposition regarding the position of the shale to be 

 correct. The following section is shown above the railroad at 

 some distance below the Vitrified Brick quarry : 



Feet. 



8. Massive somewhat calcareous sandstone - . - - 2^=37^ 



7. Rather arenaceous shales ----... 15=35 

 6. Limestone with fossils, Fiisulina cylindidca, etc. (No. 3 of 



Meek's section on p. 103 of his report) - - - - 11^2=20 

 5. Black, very bituminous shale with thin layers of coal, one foot, 



eleven inches (No. 2 of Meek's section) - - - - ii-2 = i8i^ 



4. Mainly argillaceous shales ------- 9=:i7 



3. Arenaceous shales, with thin, irregular sandstone at top - 5-8 

 2. Massive, soft and friable brownish sandstone (about railroad 



level) 2 and 3 equal division D of Meek's section - - 3 = 3 

 I. Argillaceous shales that furnish material for the vitrified 



bricks (the upper part of division C of Meek) - - - 3 = 



Numbers 2 and 3 of the above section form division D of 

 Meek's section. If the sixty-nine feet measured by Meek, which 

 are below No. 4 of the above section, be added to it there will be 

 a thickness of ninety-eight feet of Palaeozoic rocks for the river 

 bluff below Nebraska City. The rocks may be traced along the 

 bluff continuously the greater part of the distance from the Vit- 

 rified Brick quarry to the above section, which shows that the 

 stratum of shale and coal is above the sandstone (division Z*) 

 of Meek's section as he supposed.'' 



The dip in the bluff where the above section was measured 



is nearly i° to the east of south. From the rocks just above 



and below the black shale and coal in the quarry and along the 



bluff to the south the following species were collected. Meek 



spent nearly a week in the vicinity of Nebraska City, and made 



'Fin. Rep. U. S. Geol. Sur. Neb., etc., p. 103.

 report.
