CEAWFOED COUNTY. 27 



this vicinity, and I could find no outcrop of the beds below the lime- 

 stone in this neighborhood. In the western portion of the county 

 outcrops are rare, and so widely separated that no continuous section 

 could be made. 



On section 4, in Hutsonville township, at Mr. W. D. Limb's place, a 

 bed of limestone is found underlaid by five or six feet of blue shale and 

 a thin coal. In a well sunk here the limestone was found to be five feet 

 in thickness, a tough, fine-grained dark grayish rock, containing no 

 well preserved fossils. On Mr. Evans' place, just over the line of Clark 

 county, on sec. 34, T. 8, E. 12, heavy masses of tumbling limestone are 

 to be seen along the creek valley. It is a massive, gray, brittle rock, 

 and contains Athyris siibUlita, Spirifer cameratus and Productus longis- 

 pinus. A mile and a half further up the creek this limestone is found 

 in place, and is burned for lime by Mr. Drake. I believe these lime • 

 stones belong below the sandstone which is fouud at Eobinson and at 

 Hole's quarry. 



At Lesley's mill, on the N. W. qr. of sec. 7, T. 8, E. 13, a hard, dark 

 gray limestone was found in the bed of the creek, only about two feet 

 in thickness of its upper portion being exposed above the creek bed. 

 A quarter of a mile south of the mill, at Mr. Eeynolds' place, coal is 

 mined by stripping along the bed of a branch. The coal is from 15 to 

 18 inches thick, overlaid by two or three feet of blue shale, and a gray 

 limestone filled with large Producti, Athyris subtilita, etc. Productus 

 costatus, with its long spines, seemed to be the most abundant species. 

 This limestone, and underlaying coal, I am inclined to believe represent 

 the horizon of the upper coal in the bluff at Palestine landing, and No. 

 12 of the general section. 



Hutsonville is located upon a bench of sandstone, the lower part 

 of which is concretionary, and the upper part which outcrops in the 

 hills back of the town, is more evenly bedded, and affords some toler a- 

 ble good building stone. The sandstone extends below the average 

 water level of the river, and is probably altogether not less than 50 to 

 60 feet in thickness here, and is the equivalent of the sandstone at 

 Eobinson and vicinity in the cen tral portion of the county. 



.At Martin's mill, on Brushy Fork, near the south line of the county, 

 the limestone and shale found at the Lamotte creek bridge, and also at 

 Lawrenceville, representing the horizon of coal No. 11, is well exposed , 

 the creek bluff showing the following section : 



Feet. 

 No. 1. Brown sandy conglomerate and concretionary sandstone, found a quarter of a mile east 



of the mill 10 to 15 



No. 2. Space not seen 



No. 3. Micaceous sandstone and shale, top of the blutf 6 



No. 4. Brown and bluish-gray micaceous shale 18 



No. 5. Bine shale, partly calcareous, with iron nodules, and numerous fossils 4 



No. 6. Hard bituminous limestone
