Stevenson.! oUo [Oct. 7. 



The strike is almost north and south. The dip on the eastern side is 

 gentle, varying from 3 to 6 degrees, and that side of the trough is the 

 longer one. The axis of the s^ynclinal is distinct, passing at about two 

 miles from the eastern outcrop. The dip quickly becomes abrupt on the 

 western side, being first 7, then 10, then 15 and at last 40 degrees where 

 the outcrop is first reached on Oak creek, but the outcrop lies further west 

 both north and south from Oak creek and the dip becomes sharper and 

 sharper until at last the beds are perpendicular or even pushed over. 



The following generalized section of the field was made out ; but as no 

 opportunity was alforded to revise the work, it may be defective in some 

 of its details : 



1. Sandstones, with some thin shale, not ex- 



amined in detail 400' 



2. Sandstone, buflf, with occasional pockets of 



shale 45' 



3. Coal bed M Blossom. 



4. Shale and sandstone 165' 



5. Yariegated shale 170' -^

The same difficulty was experienced here as in the Trinidad coal field,
