building stone. Two and a half miles southwest of Phillipstown this 

 same ledge of sandstone forms a low cliff along the eastern face of the 

 ridge and in places is weathered into caves, locally called rock houses. 



On the road to Carmi the loess is replaced by a loose yellow sand, 

 that forms a bluff on the eastern border of a prairie, which is succeeded 

 by a shallow slough or swamp that was probably once the bed of an arm 

 if not the main stream of the Little Wabash.

Bituminous shale— black 10 



Coal 1 



Fire-clay 3 



The black shale contained some poorly preserved specimens of Poly- 

 2)liemoj>sis, Av'mdopecten and Nucula ventricosa. The argillaceous shale 

 twenty feet or more in thickness appears again on the creek a short 

 distance below the opening to the coal. 



On Limestone creek north of Enfield, T. 4 S., E. 8 E., there is an earthy 

 limestone two feet thick passing down into hard silicious fire-clay. No 

 fossils in the upper part, but the lower part contains rootlets of Stig- 

 maria. This rock has been burned for lime, and hence the name of the 

 creek. 



A thin coal is found at the following localities in this county not 

 -already mentioned: Sections 16 and 18, T. 4, E. 8; sec. 8, T. 5, E. 10; 

 sec. 30, T. 4, E. 9 ; sec. 21, T. 6, E. 8 ; sec. 3, T. 6, E. 10 ; and sec. 19, 

 T. 3, E. 9."

Building Stone — Sandstone of a fair quality for building purposes is 

 found at a number of localities in this county, as noted in the sections 

 already given in the preceding pages. At Carmi the brown sandstone 

 that forms the bed rock in the south-east part of the town is an even • 

 bedded ferruginous rock, that hardens on exposure and makes a very 

 good building stone. On Grindstone creek, six or seven miles south of 

 Carmi, on the New Haven road, a bed of gray sandstone is quarried 

 for building stone, and affords a durable stone for all ordinary purposes. 

 Near Gossett station an excellent flagstone may be obtained as well as 

 heavier bedded sandstoue for other purposes. This rock is micaceous 

 and cuts freely, and could be cheaply wrought into door sills, lintels, 

 window caps and sills, etc. 



The sandstone outcropping in the bluffs of the Wabash river from 

 • Phillipstown to Grayville affords good building stone at many points,
