Agriculture. 
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 of 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 
ahead 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 
pecopteris. 
A section of 650 feet of the rocks overlying the coal, was obtained and 
is here given in the following section:
