254 Half a mile southward, where the road begins to fol- low the railroad track, the railroad cuts show the base of the Black Shale at 1007. The brecciated Coniferums is 30 inches thick. A bluish layer is 3 feet thick. Below this are 11 feet of well stratified rocks. This total thickness of 16 1/2 ft. must be considered Coniferuns, viewed in the light of sections 35 and 38 at Crab Orchard. Below this are Ozgord clay shales, very typical. 255 At the west end of the houses near the railroad, at Crab Orchard, the creek banks show high up the base of the Black Shale. Below are 8 inches of the brecciated layer of Coniferums, 2 feet of rock with spinifex but distinct quartz grains, with masses of calcite, and a few ends. Below this are 16 feet of rock, firmly which are well stratified and unlike the ordinary Devonian as the more western ex- penses, most of the Anti-cli-nal. The lower 2 feet however are full of crinoid dal remains, contain large Crinoid stems such as are characteristic of the middle Kentucky Coni- ferums, and some can also. I immediately drove in the basal part of the well stratified beds, are found Spinifex with bringe margins 3 1/2 in does long, evidently De vonian. The intermediate are well stratified rocks almost devoid of fossils. 257 258 27 Two miles north of Crab Orchard, at James Mill, the bed of Dix River runs in the Clinton. The top of the Clinton is at 944. The top of the Ozgord clay, a mile southward is at 1022. This makes the Ozgord at least 80-90 feet thick. No account is here
