Pittsburg. The latter interval has decreased gradually from 288 feet 

 in Harrison to certainly 200 and possibly 177 in western Tyler; that 

 from the Washington has decreased from somewhat more than 270 in 

 Harrison to 180 at the last record in western Tyler, the decrease in this 

 case being as gradual as in that of the other interval. The Waynesburg 

 coal bed is not noted anywhere in Tyler. No coal or trace of coal appears 

 in record between the TJniontown and the Pittsburg. Only two detailed 

 records are available for this county. That in the southeast corner shows 

 red beds at 203 and 283 feet above the Pittsburg, and one in the south- 

 west shows a bed 75 thick at 79 feet below the TJniontown horizon, that 

 coal bed being absent, having been cut out by downward extension of 

 the overljdng sandstone.* 



Pleasants county, west from Tyler along the Ohio river, adjoins 

 Washington county of Ohio. A coal bed is reported in a well near the 

 northeast corner of the county at 1,227 feet above the "Keener" sand- 

 stone. Near Middlebourne, in Tyler, the Pittsburg is 1,229 feet above 

 the "Keener," and in another well near the Pleasants border it is 1,252 

 feet above the bottom of that sandstone. The bed in northeast Pleasants 

 is very near the place of the Pittsburg, but its occurrence is of merely 

 geological interest, as the bed is insignificant, the driller reporting only 

 3 feet in all. At Saint Marys, on the Ohio river, the TJniontown coal 

 bed is 2 to 3 feet thick and underlies a massive sandstone which is trace- 

 able up the river almost to the Tyler line. There the interval to the 

 Washington has decreased to 160 feet, 20 feet less than at the last meas- 

 urement in Tyler county. No record is here to determine the distance 

 to the Pittsburg, but at a few miles west, in Washington county of Ohio, 

 the TJniontown is 186 feet above the Pittsburg. Borings along the Ohio 

 river find no trace of the Pittsburg coal bed, which is very thin in the 

 adjacent part of Ohio.f 



Kitchie county, west from Doddridge, is south from Tyler and Pleas- 

 ants. The Monongahela is deeply buried except near the western border, 

 where the Cowrun anticline brings up still lower rocks. The Pittsburg 

 coal bed is of extremely uncertain occurrence and the detrital beds vary 

 abruptly, as appears in numerous detailed records. In the northeast cor- 

 ner the TJniontown, very thin, is 237 feet above the Pittsburg, 16 feet 

 less than at Wick, 3 or 4 miles northeast ; 2 miles farther south 25 feet of 

 hard sandstone appear at 230 feet above the Pittsburg, evidently that be- 

 longing over the TJniontown coal bed on the railroad in Doddridge county. 

 Farther south along this eastern side, for 9 or 10 miles the Pittsburg coal
