The interval between the gray and blue limestone in the section varies 

 greatly. At Mt. Eaton it is seventy five feet ; on the east line of Salt 

 Creek township, fifty feet; at Kirkendall's, some two miles east of Fred- 

 ericksburgh, twenty-seven feet; and at Fredericksburgh, on the west 

 side of the valley, twenty-two and one-half feet. Throughout this part 

 of the State, upon approaching the margin of the coal field, its strata are 

 found generally reduced in thickness, bringing the coals nearer together, 

 and showing an approach toward the original western boundary of the 

 field. This was formed by Waverly hills. The same is eminently true 

 of the interval between these two limestones. While for long distances 

 in one direction the interval between them is almost identical, a line at 

 right angles to this will show them approaching in one direction and re- 

 ceding in the other, and generally near the western margin of the field 

 they generally come closer together again.
