PULASKI COUNTY, 171 
Of these beds the ones of interest in connection with the subject 
of clays are the shale bed (No. 3) and the olive-green clay. The 
green clay is well exposed on the Seventh street pike, between \yest 
Spring street and West Sherman street, where it rests upon upturned 
Paleozoic rocks, which are exposed at this place. The following 
exposures and well records show the depth of the shales and clays 
at various points in the city:

West of the railway the olive-green clay is exposed in the road cut 
near the Catholic cemetery, in the gullies south of the cemetery, in 
the gully west of the hospital, and in another gully about 500 feet 
southwest of the hospital. It is also exposed in the bed of the branch 
just east of the hospital, and also toward the top of the ridge to the 
east. 
The following is the record of a well put down west of the railway, 
about 300 feet northeast of the center of the south side of sec. 8, T. 1 
N., R. 12 W., as reported by Mr. Siebenthal.

East of the railway near the center of sec. 16, T. 1 X., R. 12 W., 
there are several exposures of the shale and of the olive-green clay. 
On the east slope of the ridge that runs along the east side of sec. 16 
this same green clay is exposed here and there. It is exposed also in 
the gullies beside the road leading southwest from the Arch street 
pike, in the SW. J sec. 15. 
A well on the east side of the Arch street pike, 200 feet south of the 
northern edge of sec. 15, passed through soil, gravel, yellow clay, and 
tough blue clay, and got water at 27 feet in gravel. This clay bed is 
probably the same as that exposed in the gully on the slope of the hill 
below, where the road turns southwest from the Arch street pike. 
A well at the southeast corner of Arch and Twenty-third streets 
passed through S feet of gravel and sandy clay and 10 feet of yellow 
and blue Tertiary clay. This is doubtless the same blue (day bed 
again. 
At the end of the ridge east of the Rapley house and north of Vct- 
tifer's brickyard the olive-green clays are well exposed to a thickness 
of 40 to 45 feet. The olive-green clay and dark shale were found in
