to the Logan sandstone. Here one is at the extreme point of the " Pan- 

 handle," 2 miles west from line of Beaver county, Pennsylvania, and at 

 about the same distance from the northern part of Jefferson county, 

 Ohio. It is very possible that number 5 represents the Sharon sand- 

 stone, for the southern limit of that bed is not far north from this lati- 

 tude in western Pennsylvania. The well at McDonalds, in Washington 

 county, Pennsylvania, is about 15 miles east-northeast from Wellsburg. 

 Its record shows little aside from shale for 886 feet below the Pittsburg 

 coal bed. The Pottsville is 256 feet thick, including 58 feet of black 

 shale resting on the Logan, which is 1,142 feet below the Pittsburg, an 

 increase of 107 feet in 15 miles, due wholly to increase in the Conemaugh 

 and Allegheny, the Pottsville having decreased 16 feet in the interval. 

 In the same way one explains the small intervals in West Virginia near 

 the Pennsylvania line. At McDonalds and Morgantown the intervals 

 are, to the

showing a decrease southward of 53 feet in the Conemaugh and of 45 

 feet in the Allegheny. The loss is regained farther south.* 



Returning to the southeasterly side, one finds at Fairview, in Marion 

 county, about 20 miles south of west from Morgantown, the top of the 

 Pottsville at 808 feet below the Pittsburg. The section is

 in thickening of the shales, numbers 2 and 3, at the expense of number
