with the Leave«worth rock? Probably the lower, as the series (a), (b), (c), 

 has more resemblance to the Leavenworth series than any other part of the 

 section. The thicknesses of the upper part of this section suggest similarity 

 to the section at Fort Leavenworth. The dimension rock (a) at the ravine 

 half a mile east of Quindaro, where it is best seen, is at the railway level. 

 There is a northerly dip here which carries it out of sight at the old Quindaro 

 ravine. At Connors, a slope yielded little distinct outcrop; but at 75 feet 

 above the railway a quarry is worked in 15 feet of limestone, and 70 feet 

 higher, limestone is again seen 8 or 10 feet thick on top of the ridge. A little 

 west of Pomeroy the following section was obtained: 



C. 



i. Limestone in several rough layers 10 ft. 



h. Slope (shale ?) 20 ft. 



g. Limestone 6 or 8 ft. 



f . Shale 17 ft. 



e. Limestone 10 ft. 



d. Shale 16 ft. 



c. Limestone 5 ft. 



b. Black laminated shale ^ 2 ft. 



a. Layer of limestone ll^ ft. 



Further west more precipitous bluffs show that the limestones are thicker, 

 upper and lower soft layers having in the section been weathered and hidden 

 in the stopes. (g) Shows fully 15 feet, (a) Is 10 feet above the railway track; 

 but nothing shows below. Nearly all stopes are topped with the yellow clay 

 — the loess. It is almost impossible to trace any bed of rock inland, owing 

 to the great erosion and the covering of loess. At the quarry, where the 

 shale is obtained for the Adamant brick works, and the ravine below, this 

 section was obtained with some approximation to certainty: 



D. 



Loess. 



Limestone 1|^ ft. 



Shale, brownish 2 ft. 



Blue shale (brick) 15 ft. 



Limestone, three or four layers : 2y2 ft. 



Greenish blue shale 4 ft. 



Limestone ledge, top just seen. 



In the Kaw valley, the following section is obtained at Armstrong: 



E. 

 h. Rough limestone, about 20 ft. 



g. Shale (brick) 10 ft. 



f . Limy ledge 1 ft. 



e. Shale or shaly rock 3 or 4 ft. 



d. Layers of limestone, flinty, 2 or 3 ft., thickening westward 



to 9 to 11 ft. 



c. Shale, carbonaceous, and clay 2^^ ft. 



b. Massive limestone 6 ft. 



a. Limestone 1 ft. 



This is not unlike the Quindaro section, and may be taken as the preva- 

 lent arrangement of the bed rocks up to the elevation it reaches all over the 

 city area and some distance west. Something else comes on at higher levels, 

 (d), In the above section, is at the railway level at Martin's dairy; but (e) 

 is above that level a little further v/est. 



A section further west, where the river and railway come close under the 

 bluffs, and the highroad is on a shelf above, is as follows:
