I believe the problem with Victoria level may have been because they 
followed the base of the main lime and so the rise in the level refelcts the 
rise in the beds. However as i am reliing on second hand information albeit 
from a mining engineer i cannot confirm this.

As to the comments about the connection between Bunting and Hard level, i 
have to agree with Mike it was not an error. The agents notebooks indicate 
that the connection on the Old Rake vein was equiped with a pair of "metal 
hoppers". I would suggest that this referes to hoppers for metal not hoppers 
made of metal. So this would indicate that the hoppers served as a 
collection point for ore from the west side of the Old Gang Mine complex 
which could then be trammed out of Hard level to the dressing floor and 
smeltmill. One question that this raises is why use the term "metal hopper", 
does this suggest that it was dressed material trammed in from the Bunting 
dressing floor that was tipped down the hoppers? This dressing floor apears 
to have worked throughout the 19th century and the easiest way to transport 
dressed ore to the companies smelt mill would have been through the mine.

The question of how well the surveyors and engineers knew the local geology 
is an interesting one. Boring rods had been used during the 1680s when they 
were used to drain a shaft and to provide air. It seems hard to imagine that 
they were not also used to prove the position of the bearing beds and 
possibly the position of the veins.
