70 feet below the limestone, but the rest of the interval is concealed. 

 A limestone seen elsewhere was supposed to be about 150 feet below the 

 Nineveh. The longest section in the state is that measured by Professor 

 Andrews at Baresville, in Ohio township. Somewhat condensed, it is:

ending at 45 feet above the Ohio river. The highest coal bed is taken 

 to be equivalent to that seen in southwestern Pennsylvania. This cor- 

 relation is especially probable, because, unlike the lower intervals of 

 the Dunkard, that from the Nineveh limestone to the Gilmore sandstone 

 is strangely u^niform in the area of western Greene and the immediately 

 adjacent part of West Virginia. The succession below the Nineveh 

 limestone is the same as at Switzerland. The same limestone is seen on 

 the opposite side of the river, where Doctor White made the interval 

 382 feet to the Washington coal bed; the difference is due, no doubt, in 

 part to neglect of dip and in part barometric variations, for the measure- 

 ment is not direct in either case. Doctor White long ago correlated this 

 limestone with the Nineveh, and his suggestion has been confirmed by 

 the observations in northern West Virginia, which show one constant 

 limestone horizon between the place of the Upper Washington and the 

 Gilmore sandstone. The exposure appears to be practically complete 

 at Baresville between the Jollytown and Washington coal beds, but there 

 is no red shale present, which accords with the New Martinsville section 

 on the opposite side of the river, where the red beds are so insignificant 

 that they might be overlooked. The interval between the Washington 

 and Uniontown coal beds is 24 feet more than in Center township. 

 The Waynesburg A is concealed here as well as at Sardis, in the southern
