but its stratigraphical position cannot be far from that assigned it in the 

 following section : 



Ft. In. 



1. Coal, Cumberland seam 4 10 



2. Interval not exposed 102 



3. Iron ore 6? 



4. Bed shale 15 



5. Sandstone chiefly 17 



6. Shale 8 



7. Limestone 2 



(Map XII., No. 32.) 



The ore is a sesquioxide of iron but slightly hydrated, the combined 

 water being only 4.60 per cent. The following is the analysis of the ore 

 by Prof. Wormley : 



Water 4.60 



Silica 10.76 



Sesquioxide of iron 80.51 



Alumina 1.20 



Magnesia ... 1.30 



Lime 1.30 



Phosphoric acid Trace. 



Sulphur 0.0 



Total 99.67 



Metallic iron 56.36 



The ore is rich in iron, and its remarkable freedom from phosphorus 

 and sulphur makes it the best possible material for an iron for conver- 

 sion into steel. The location is worthy of careful investigation to deter- 

 mine the quantity of ore. In the slide of the hill-side were large, lamin- 

 ated blocks of ore six inches thick. When the ore is traced to its 

 original stratum it may be found much thicker. It is an ore of very 

 great promise. The coal of W. C. Bevan, section 26, is the Cumberland 

 seam. The lower bench is reported to be four feet thick, and the upper 

 one foot eight inches. 



On the land of W. W. Collins, below Carlisle, the Cumberland seam of 

 coal is two hundred and twenty feet above the East Fork of Duck Creek. 

 The lower bench is about five feet thick, separated from the upper bench 

 of ten inches by two feet of clay. A sample from the lower bench was 

 analyzed by Prof. Wormley, with the following result : 



Specific gravity ■ 1 - 338 



Moisture L1 ° 



Ash 1130
