FAYETTE COUNTY. 139 



short distance. Other bowlders found here are of granite, sienite and 

 quartzite. 



At the mill on Beck's creek, in sec. 10, T. 8 K., R. 2 E., Coal Measure 

 limestone is seen apparently resting on a bed of drift; some of the sand 

 and pebbles are even cemented to the limestone, which must have been 

 overhanging when the drift was deposited, and the latter washed 

 beneath. 



Mounds. — In the western part of the county there are many mounds 

 rising above the general surface of the country 50 to 90 feet, and occa- 

 sionally there are a few east of the river. The various clays, sands and 

 pebbles found on these mounds, and entering into their composition, 

 present the same character peculiar to mounds found iu other counties. 



Among the drift bowlders found in this county are sienite, granite, 

 hornblende rock, greenstone, quartzite, sandstone, limestone and clays 

 from the Coal Measures. No very large bowlders were found. 



Coal Measures . - 



On account of the non-appearance of certain intermediate beds neces- 

 sary in the connection, we can only approximate the thickness of the 

 Coal Measures in this county; but there is sufficient data to assume 

 that the total thickness may reach 350 feet, ranging from No. 1 to No. 

 46, of the section of upper Coal Measure strata, and include the horizon 

 of four coals, viz : 13, 14, 15 and 16, although the latter has not yet 

 been found in the county. 



The rocks occupying the highest geological horizon in this county are 

 probably those on Dismal creek, of which the following is a section : 



Ft. 

 No. 1. Sandy shale 10 



No. 2. Buff limestone, upper part nodular, middle in even layers ; no fossils seen 5 



No. 3. Clay shales with nodules, middle red, remainder olive-colored 12 



No. 4. Sandy shales and thin beds of hard, gray sandstone 24 



The next highest beds are found on Hickory and Rock creeks : 



On Hickory Creek. 



Ft. 

 No. 1. Sandy shales ; in the middle are dark micaceous and carbonaceous partings, below there 



are occasional thin beds of sandstone, color yellow, drab and gray 20 



Ho. 2. Sandstone, hard, gray, and brown, ferruginous and yellow ; part of it for 100 feet horizon- 

 tally is a vermilion red, containing Lepidodendron and Sigillarice 5 



No. 3. Slaty coal and bituminous shalo, passing into a cannel coal, at Odell's contains Solenomya, 



radiata and Avicidopecten Whitei, equivalent to No. 15 Shelby coal 3 



No. 4. Dark blue clay shales, stained brown 1 



No. 5. Tellowclay 2 



No. 6. Soft yellow sandstone and shales 3 



No. 7. Greenish-blue clay shales - - 2 



In passing down stream a quarter of a mile the rocks rise 1 foot iu 

 60.
