136 Cnal-Seams of Va?i Diemefi's Land. 



In this shaft the beds passed through were, — 



Blue argillaceous marl or shales with numerous ^ 70 f pt 

 fossil shells, Producti, Spiriferse, &c j 



Hard grey sandstone and conglomerate rock, ~)^aa^ j. 

 fossil shells very scarce : j 



Total 270 feet. 



Here agaiu we have a shaft 270 feet deep sunk entirely 

 through beds beneath the carboniferous series, and in which, 

 of course, no Coal was discovered, — nor, as I told Mr. 

 Williams, would he have the smallest chance of finding 

 Coal were he to sink another thousand yards : he, however, 

 is firmly persuaded to the contrary, and intends, if he can 

 raise funds, and find men to undertake the work of sinking 

 through a quartz conglomerate nearly as hard as cast-iron, 

 to carry the shaft deeper. 



About on© mile north-west from this shaft Mr. Williams 

 has discovered a seam of Coal cropping in a small water- 

 course ; it is about 3 feet thick, and dips (S. 23° E.) 3°. 



He had only just commenced opening into it at the 

 period of my visit. I have been informed since that, follow- 

 ing it up the hill, or on the rise, it was found to be suddenly 

 cut off and completely thrown out by a fault : in the oppo- 

 site direction or on the dip it is evidently cut off between 

 the place opened and the deep shaft towards which it dips, — 

 so that there would be only a narrow strip of coal measures 

 let down by faults between the lower fossiliferous beds. See 

 Section PL V. fig. 1. 



Notwithstanding this, unless the two above-mentioned 

 faults are within a very short distance of each other, run 

 together at an acute angle, and are also crossed at a short 

 distance in the opposite direction by another fault, thus 

 forming a small triangular patch, I think Mr. Williams 

 will be able to raise a considerable quantity of excellent
