360 Mr. Kingston's Account of the Iron Mine 



termed Ironstone) of a compact basaltic texture, and great spe- 

 cific gravity ; and mostly containing a proportion of iron-ore, 

 which occasionally runs in distinct threads and patches through 

 small portions of it The lode occurs in the clay schist, and 

 the direction of its strata is nearly North-west and South- 

 east, underlying to the North-east at an angle of 22° or 23° 

 only for the first few feet from the surface ; but below this the 

 dip is very regular at an angle of 45°. It happens to be si- 

 tuated in two distinct estates, which a road, intersecting the 

 lode near the centre, divides ; and having hitherto been worked 

 separately, a complete wall from the surface to the depth ex- 

 plored, has been left, of which the following is an accurate 

 section and measurement; the measurement is taken at the 

 depth indicated by the dotted line, which is also the direction 

 of the level driven from the back of the lode. 



16 feet ore. 

 1 2 feet schist. 



26 feet whole width of lode.
