enable one to speak finally about distribution of the red shales. The bed 

 belonging under the Uniontown coal bed is 15 feet thick on the Tyler 

 border, but along the eastern side the beds are thin and unimportant.* 



Tyler county, southwest from Wetzel along the Ohio river, is north- 

 west from Doddridge and adjoins northern part of Washington county of 

 Ohio. The number of oil wells in this county is very great, but for the 

 most part the records are merely skeletons in much of the county, com- 

 paratively few making any note above the Pittsburg horizon. That coal 

 bed is recorded in many wells along the Doddridge border, but is absent 

 from many others, while in by far the greater part of the county it is 

 represented by a mere trace or is wholly wanting; but the horizon can 

 be carried without difficulty along the strike lines by means of the Logan 

 (Big Injun) sandstone. 



A record just over the line in Doddridge eount}^ notes the Uniontown 

 coal bed at 250 feet above the Pittsburg. In southeast Tyler, near Wick, 

 a detailed section shows the Uniontown, very thin, at 253 feet above the 

 Pittsburg and 36 feet above a 15-foot bed of red rock, which is very 

 near the place of a bed in a Doddridge well 10 miles northeast. At Wick 

 this coal bed underlies 30 feet of coarse sandstone, as it does near Smith- 

 ton, 5 or 6 miles southeast on the railroad, and it is 191 feet below the 

 Washington, a very notable decrease from Harrison county, where the 

 interval is 273 feet within the Sardis district. The Washington is 538 

 feet above the Pittsburg in Sardis, but only 444 feet in southeast Tyler. 

 The interval, Uniontown to Washington, is almost 30 feet less than at 

 Pine Grove, in Wetzel, 20 miles north-northeast. 



More information is available along a line 7 to 8 miles northwest from 

 this Pine Grove- Wick line. The Uniontown coal bed is noted in most of 

 the records giving any information above the Pittsburg horizon. On 

 the Wetzel border, 6 miles east of south from New Martinsville and at 

 the same distance southeast from Sardis, in Monroe of Ohio, the interval 

 from Uniontown to Pittsburg is 240 feet; farther southwest to the 

 Eitchie-Pleasants line the Uniontown is almost constantly present at 

 1,460 to 1,470 feet above the Logan sandstone and 220 to 230 feet above 

 the Pittsburg, where that bed is present. The interval to the Pittsburg 

 decreases still more toward the west, becoming 210, and then 200, while 

 at 8 miles from Middlebourne, on the Pleasant border, a record shows 

 what seems to be this bed at 177 feet. The changes in relation to the 

 Washington are quite as interesting as those in relation to the
