The heavy shale bed above this corresponds well with the shale below 

 the Garnett limestone and above the Carlyle, but this system hardly 

 compares whh. the Carlyle limestone. The distance is so great that 

 it is unsafe to carry the correlation further than merely to point out 

 the similarity and suggest the possible identity. 



The lowest of these two strata is just above the road bed below 

 Holliday, but above the station it is below the surface. It has one 

 thick layer which possibly would render it valuable for the proiluction 

 of dimension stone. The upper stratum also has an unusually thick 

 layer.

The contact between the rocks of the Mississippian series and the 

 Coal Measures, as exposed on the surface, is a short line in the e.xtreme 

 southeast part of the state not more than eleven miles long. In addi- 

 tion to this along a number of valleys necks of the Mississipian rocks 

 extend to the northwest a few miles, and in other places the Coal 

 Measure shale sare so thin they have been passed in well digging and 

 prospecting for ores in different parts of Cherokee county. This is 

 abundant evidence of a wide-spread nonconformity between the two 

 rock systems, although such nonconformity is never strongly marked. 

 By this it is meant that the angle between the two systems is a small 

 one, producing almost parallelism of strata. It shows itself rather in 

 the nature of surface irregularities at the top of the Mississippian 

 series, indicating an extensive surface erosion previous to the forma- 

 tion of the Coal Measure rocks. 



The difference in position of strata of the two series may be judged 

 from the following data: The surface of the Mississippian rocks 

 at the railroad bridge on Spring river, one-half mile east of Lowell 

 station, is about 815 feet above sea level, the elevation at the station 

 being 825. At Oswego, twenty-one miles away by an air line, the same 

 horizon was met in a drilled well, according to data kindly furnished 

 by Dr. Newlin, of Oswego, at a depth of 500 feet below the surface, 

 which is equal to 389 feet above sea level. This gives a dip of 20 3 

 feet to the mile. At Cherryvale the same series was reached in the 

 diamond drill hole at 1005 feet below the surface, which is the same 

 as 165 feet below sea level, or 980 below the same surface at Spring 

 river. The air line distance between the two points is 47 miles, 

 which gives a dip for the surface of the Mississippian series equal to
