but below the last the rock is described as "broken and limy," so that 

 the full thickness of the silicious limestone is not given in the record. 

 An unexpected feature is the practical disappearance of the topmost 

 limestone of eastern Lewis, 95 feet thick, which is represented at Vadis 

 by 50 feet of limestone and 30 feet of shale. The red rock has increased 

 greatly, and of the upper limestones there remains only the lowest bed. 

 Meanwhile there has been a decrease in thickness of the section and 

 the sandstones are represented only by fine material ; the Logan, as a 

 sandstone, has disappeared, and the driller found nothing worthy of 

 record for 639 feet below the limestone. 



Doctor White gives no record for wells in Calhoun county, that ad- 

 joining Gilmer at the west, but a record at Burning Springs, in Wirt 

 county, 28 miles northwest from Glenville, shows under the Pottsville 

 115 feet of limestone, "very hard, and lower half mixed with sand." 

 Burning Springs is but 10 miles south from the locality in southern 

 Ritchie, where 67 feet of limestone represents the whole series. Spencer, 

 in Roane county, is 30 miles south of west from Glenville and barely 15 

 miles south from Burning Springs. There the limestone is 75 feet, the 

 lower 45 feet being " gritty ; " 20 feet of shale and sandstone intervene 

 between it and the Pottsville sandstone above, and it rests on the blue 

 shales of the Logan. In another well, 11 miles southwest from Spencer, 

 the limestone is 86 feet, the lower portion for 25 feet being " gritty, very 

 white," while the upper part is gray. This well is about 40 miles west 

 from that at Sutton ; within this distance the limestone has decreased 

 360 feet. 



Jackson county lies west from Wirt and Roane. The record is at 

 Ravenswood, on the Ohio river, 25 miles from Spencer, 30 from Burn- 

 ing Springs, and 25 south of west from Parkersburg, in Wood county;
