Sbalo 4 



Lime stone 5 



Shale 6 



Coal No. 7 4

The coal at this entry is one hundred and forty-six feet above high 

 "water, showing a rise to the south-west of forty-eight feet in nineteen 

 hundred and fifty.

Shale 6 



Coal No. 7 4 



Fire-clay ? 



At the Forrester entry, near the middle of section 8, the elevation is 

 one hundred and thirty-nine feet above high water, showing a difference 

 of only seven feet in half a mile, which apparently indicates that it is 

 nearly on the strike of the formations on this part of the hill. The 

 limestone here has diminished to two feet. 



At the Barlow entry, near the middle of the south-east quarter of 

 section 8, the coal is eighty-four feet above high water, which shows 

 a dip S. 10° E., of fifty-five feet in a horizontal distance of fourteen 

 hundred and fifty feet. 



Section at A. Barlow entry : 



Ft. In. 



Shale 6 



Coal No. 7 4 



Fireclay ! 



At this entry, on the north side of section 8, the coal is one hundred 

 and twenty-eight feet above high water, and the limestone is absent, 

 being replaced by shales. The coal is four feet thick and has the 

 sulphur band and clay parting. 



On the north-west quarter of the same section, the limestone is in 

 place again, and the coal is one hundred and two feet above highwat'r, 

 showing a south-west dip of twenty-six feet in one thousand one hun- 

 dred. On the north-east quarter of section 7, at the Jones entry on 

 Coal creek, No. 7 coal is at high-water mark, showing a dip of 6° or 7° 

 to the west, and a fall of one hundred and two feet from the last entry, 

 in rather less than half a mile. 



At the town of Equality on the western boundary of the county, 

 Nos. 5, 6 and 7 occur in their regular sequence, as seen at Bowlsville, 

 the Independent Company's mines, and other jilaces. At these local- 

 ities all three beds have been opened, and more or less mined, to supply 

 the home market. 



No. 7 is usually four feet thick in the many openings where it is 

 mined in the streets, and around the town. The miners report the dip
