The northern part of Franklin county, though much broken, contains a 

 large amount of good tillable land on the creek and river bottoms, which 

 is very productive, when properly cultivated. The principal growth of 

 timber is white, black, and redoak, blackjack, postoak, and hickory, sweet 

 and black gum. 



JOHNSON COUNTY. 



A number of openings have been made into a seam of semi-bituminous 

 coal, on the waters of Horsehead creek, in Johnson county. The princi- 

 pal of these are the Wilmoth coal, section 18, township 10 north, range 

 25 west; Butts' coal, section 8, township 10 north, range 25 west; Lee's 

 coal, section 15, township 10 north, range 25 west; Flemming's coal, sec- 

 tion 1, township 9 north, range 25 west. These coals are all opened in 

 an extensive plateau formed by the easily-weathering mass ol shales 

 underlying the massive sandstones of the millstone grit series, which are 

 seen prominently capping the mountains, a short distance to the north. 



The Wilmoth coal bed, from 20 to 22 inches thick, is worked by drift- 

 ing; it has a dip of 6 or 8 degs. to the south-east, and rests on a dark fire- 

 clay bottom, filled with stems of stigmaria. In mining the coal, some 

 eight inches of the roof falls down and has to be carried out, which gives 

 a head room equal to about thirty inches. In this dark earthy looking 

 shale, is found a small, undescribed species of fossil shell, belonging to 

 the genus modiola, and fragments of plants belonging to the genus 

 2>e copter is. 



A section of 650 feet of the rocks overlying the coal, was obtained and 

 is here given in the following section:
