WALDRIP DIVISION. 209 



two miles. About a mile north of this is another coal outcrop, having 10 

 feet of clay between it and the limestone. In boring for coal in the same 

 region near where coal has been found, and at a place where it would cer- 

 tainly be expected, the seam of coal has not been found. This marked vari- 

 ation in a small area is an example of what is noticed over the entire extent 

 of the Waldrip division. The beds are very variable, both in small areas 

 and in a general way, over the entire district. In some places the strata 

 above and below the coal contain great quantities of rich nodular ironstone, 

 as on Bull and Home creeks; but on the Jim Ned this feature is almost un- 

 noticeable. 



A section at the Finks mine at Waldrip, beginning at the surface: 



Feet. In. 



1. Quarternary conglomerate (loosely consolidated) 



2. Massive sandstone (ripple marked) 5 



3. Shaly sandstone with considerable clay 10 



4. Fossiliferous compact limestone 1 



5. Yellow clay (with nodules of pure kaolin) 3 



6. Yellow fossiliferous clay 1 3 



7. Blue clay rock with thin bands of carbonaceous shale and laminae of coal .... 1 8 

 *8. Alum clays (white, yellow, and black) with white and yellow alum efflor- 

 escence 1 3 



9. Hard flinty limestone .... 8 



10. Clays 23 



11. "Slate" (clay shale) 18 



12. Coal 2 



13. Fire clay 1 6 



14. Hard slaty rock 5 



* This is above the top of the Waldrip shaft. Mr. W. H. Nichols, former owner of the mine, gave me sec- 

 tions 9 to 14. 



At Home Creek, in the Dunson and Kingsbury pasture, coal outcrops with 

 a thickness of 28 inches. Below the coal is fire clay, and above it are layers 

 of clay, shale, and clayey limestones, with a thickness of about 40 feet, and 

 this in turn is covered by about 25 feet of shale, mostly sandy shale overlaid 

 by limestone. Owing to the peculiarity of weathering in these soft beds it is 

 very difficult to construct an accurate section based on surface observations. 



One more section in the coal beds will be given, and this at the Silver 

 Moon mine in the Jim Ned, the northernmost point to which I have traced 

 the Waldrip coal seam. This section was furnished by Mr. D. B. Slater, 

 who did the work on the shaft and made careful notes of the strata passed 

 through. Beginning at the top, the section is as follows:
