Luccock's boring, appears to be of excellent quality. An analysis of a 

 specimen from Mr. Miller's opening gives the following : 



Specific gravity 1.267 



Moisture 3.00 



Volatile combustible matter 36.20 



Fixed carbon 58.00 



Ash 2.80 



Total 100.00 



■ Sulphur 1.97 



Sulphur remaining in coke 0.90 



Sulphur forming of the coke 1.68 



Fixed gas per pound, in cubic feet ; 3.88 



Character of the coke Compact. 



Color of ash Dull white. 



Coal No. 6 is worked near Liberty by Messrs T. S. & S. W. Luccock, 

 section 23, and by Mr. James Gibson, section 22. At these openings the 

 coal varies little from three feet in thickness, and is of very good quality. It 

 is also worked by Mr. G. B. Leeper, section 8, who has it thirty-five inches, 

 and by Mr. Miller, juat above his shaft upon Coal No. 4, where it is only 

 thirty-three inches thick. It shows no well-defined parting, and varies in 

 character considerably. At one of Mr. T. S. Luccock's banks it is very 

 soft and clean, with but little pyrites visible, while in several of the 

 others it is hard, irised, and containing no inconsiderable amount of sul- 

 phur. A specimen from Mr. T. S. Luccock's bank gives the following 

 upon analysis : 



Specific gravity 1.253 



Moisture 3.20 



Volatile combustible matter ). 35.40 



•Fixed carbon : 58.40 



Ash 3.00 



Total 100.00 



Sulphtir 2.60 



Sulphur remaining in coke 1.18 



Sulphur forming of the coke 1.92 



Fixed gas per pound, in cubic feet 3.36 



Character of the coke Compact. 



Color of ash Brown. 



On the property of Mr. W. Ralston, section 17, is the most southerly 

 exposure of Coal No. 6. The section is : 



FT. IS. 



1. Lead-colored shale S 



2. Black fissile shale 4 



3. Coal, "bone" 4
