Over the surface of the shale and through the sandstone flows the 
water with which the city is supplied. The thin stratum of sand- 
stone contains many of the fossil forms described by Meek as be- 
longing to the Dakota, and later by Cragin as to the Mentor beds. 
Khe bluffs on each side of the Solomon river are covered with layers 
of Benton limestone. Near Solomon Rapids the following section 
may be observed, numbering from the bottom: 
4th, Alternate layers of limestone and shale, 20 feet. 
ad, Limestone, 4 foot, Inoceramus liabatus. 
2d, Limestone (Lincoln Marble), 5 feet. Shark’s teeth abundant. 
ist, bituminous shale, 40 feet. 
The Lincoln marble contains abundant remains of shark’s teeth, 
and is about the same thickness as that found fifteen miles south on 
Salt creek. 
In arailroad cut at Glen Elder the following order of stratigraphy 
may be observed, numbering from the bottom: 
10th, Soul, 2 feet. 
9th, Limestone, 8 inches. 
8th, Shale, 2 feet, yellow color, Ostrea congesta. 
(th, Shale and limestone, alternate layers, 20 feet. 
6th, Limestone, 4 inches, /noceramus horizon. 
oth, Shale, 6 feet. 
4th, Limestone, 3 inches, white. 
3d, 2 feet of shale, light blue, with /noceramus. 
2d, 4 inches of blue colored limestone resembling shale in texture. 
ist, 10 feet of black shale closely textured. 
Passing north from Glen Elder the Benton limestone which is 
found on the bluffs at that point rapidly disappearing under the 
eradually thickening Ostrea shales. These, in turn, disappear under 
the Blue Hill shalés, which, twelve miles north, in the vicinity of 
Jona, are capped with the Ft. Hays limestone of the Niobrara. 
Farther toward the north, in the vicinity of Burr Oak, the Pteran- 
edon beds rest on the F't. Hays limestone. 
South of Glen Elder the Benton limestone disappears under the 
Ostrea beds and outcroppings are seen only along the streams. 
The country is comparatively level, with a gradual slope, until the 
liills are reached, when there is a rapid ascent of from 100 to 200
