belonging in this interval are apparently absent. In the Raleigh, num- 

 ber 6 is 266, and number 4, 517 feet above the Eagle, not far from the 

 intervals for Cedar Grove and Winnifrede in the upper Kanawha region. 

 Number 10 is 207 feet, only 15 feet more than the interval between the 

 Eagle and Campbells Creek near Brownstown. The condition in Wyo- 

 ming county leads to the belief that this interval is greatly increased 

 southward, with a corresponding decrease in the interval between the 

 Campbells Creek and the Cedar Grove. Number 10 of the Wyoming 

 section appears to be, almost without doubt, the equivalent of the Camp- 

 bells Creek, and it is almost 240 feet above the Eagle. The " Cook " or 

 " Big bed " of northern Wyoming has been identified with the Campbells 

 Creek by Doctor White and Mr d'Invilliers, both of whom have given 

 many sections. The bed has been traced for the Guyandotte Coal Land 

 Association around a large area, openings having been made at short 

 intervals, so that there seems to be no room for doubt of its identity 

 with the Campbells Creek. The bed, number 13, has its great thickness 

 only locally, and elsewhere in Wyoming county is very thin. It is not 

 far from the place of the Brownstown, and is evidently at the same hori- 

 zon with number 12 of the Raleigh section. The Cedar Grove near 

 Oceana is but 86 feet above the Campbells Creek, which is double, triple, 

 or even quadruple, and shows the same tendency to variation as on the 

 Kanawha. The highest beds in both sections are taken to be at the same 

 horizon, and probabl} 7 represent the Coalburg. 



Doctor White gives a section in southern Logan county, almost due 

 west from Oceana, as follows :

to massive sandstone. The succession is made sufficiently clear by com- 

 parison with the Wyoming section. The interval from the Sharon sand- 

 stone to the Eagle coal bed has increased, being 70 feet more than at
