was seen at Wheeling. Number 8 is the Bemvood limestone and is made 

 up of alternating layers of shale and limestone 3 to 6 feet thick. The 

 Sewickley horizon includes Numbers 9 to 14. In these sections the 

 vertical thickness is about 34 feet, but Doctor White found the three 

 Wheeling beds in a vertical space of 43 feet at another locality within 

 the limits of that city. The bottom bed is the Lower Sewickley and rests 

 on limestone which may be taken as the Fishpot; the upper two at 

 Wheeling are equivalent to the single bed of the second section and to 

 the Upper Sewickley of Pennsylvania, the Meigs Creek of Ohio. The 

 section remains above the river to a mile below Benwood or five miles 

 below Wheeling. At 12 miles below Wheeling, near Moundsville, Doctor 

 White obtained measurements showing the Waynesburg coal bed 3 feet 

 thick and 365 feet above the Pittsburg. The Uniontown limestone is 

 3 feet and separated by sandstone from the great Benwood limestone. 

 At 35 feet below the last is a thin coal bed, 44 feet above the Pittsburg, 

 which is at the place of the Lower Sewickley. The place of the Union- 

 town coal bed is concealed. At about 13 miles south from Moundsville 

 Mr J. E. Barnes made borings with diamond drill which show a notable 

 increase in thickness, especially in the upper part of the section.

In the second section the interval from Waynesburg to Uniontown 

 is an estimate, as the core begins below the upper bed. The Waynes- 

 burg is about 300 feet above the Pittsburg, but the interval from the 

 Uniontown. to the Pittsburg is almost the same as at Wheeling; the 

 relations of the Upper Sewickley show equally small change. The lime- 

 stone is still in notable quantity throughout the section. A new feature 

 appears in the presence of red shale, unknown in the Monongahela of 

 Pennsylvania and farther north in West Virginia. One of these borings 

 shows four layers, in all 8 feet thick, between Waynesburg and Sewick- 

 ley, the lowest at 60 feet above the latter coal bed; another shows six
