The seam where thus constituted yields a little less than 8 feet of 
coal. The output of this mine has established itself as a good furnace 
coal, but only the lower benches of the seam were used for this purpose. 
The same conditions and descriptions apply in «sll respects to the 
mines of the Newark Coal Company and the XX Furnace. 
Card and Upson’s mine is the last of the Shawnee list. Its terri- 
tory extends almost to the northern limit of the field. It comprises an 
undisturbed and regular body of the great coal, which averages 9 feet 
in thickness, and in which no interruption worthy the name has yet 
been found. ‘The structure of the seam is shown below:
