10. Variegated shale 28' 



11. Coal bed B 1' 3" 



12. Shale and thin sandstone , 25' 



13. Coal bed C Blossom. 



14. Sandstone and shale, estimated 45' 



15. Coal bed B 1' 2" 



16. Shale 16' 



17. Bider coal bed 0' 10" 



Coal bed B is shown on the low hill alongside of the road, at a few rods 

 above the trestle ; it seems to be hard and fairly clean coal. The upper 

 part of the interval, No. 14, is occupied by a massive, soft, yellowish 

 white sandstone, which is about 20 feet thick. Coal bed C is represented 

 by carbonaceous shale, which was followed up the gulch to where it passes 

 under the surface. The interval between it and Coal bed D was estimated. 

 The rest of the section was obtained on a projecting point opposite a gap 

 in the hill, lying between the road and the gulch. Coal bed D is shown 

 on both sides of the stream, but is thicker on the southerly side, where it 

 shows 23 inches of coal. 



Coal bed F appears on the bluff, where its blossom measures 4 feet 6 

 inches, but a good exposure occurs at a few yards further up the gulch, 

 which exhibits the structure of the bed in detail as follows :

Coal 1' 7"

Coal 0' 9" 



The coal is sulphurous and dirty, so that it is of little value. The over- 

 lying shale is fissile and verj' black. Coal bed G is exposed under the edge 

 of the sandstone which caps the bluff". This rock is reddish-yellow, 

 mostly massive and occurs in cliffs. The thickness appears to be up- 

 wards of 40 feet, but exposures further south show that Coal bed H belongs 

 at but a little way above Coal bed G, and the thickness of the lower sand- 

 stone is not more than 15 feet. The rock above Coal bed H is the one form-
