The continuity of the lower bed appears to be broken west ofHuntsville, but, near the west line of the county, in Charitoncounty, what is apparently the same bed is operated on AsaGunns land, in section 31, township 54 N., 16 W.

South of thispoint, on the Wabash railway, are two shafts, now abandoned,which probably operated the same coal bed. East of Huntsville, towards Moberly, there are some fourshafts along the Wabash railway, and others north of this road,each about 100 feet deep, operating the four fopt bed. Thecharacter of the coal and the section here is essentially the same at Huntsville. Two upper coal beds are found, the firstgenerally about 20 feet above the four ft. bed and ranging from15 inches to 24 inches in thickness. The other bed, 14 feetabove the last, is about 18 inches thick. The last is generallygood coal and is occasionally worked. Immediately adjacentto Moberly no coal is worked, and the indications are that itha
