Huddersfield Narrow Canal / Standedge Tunnel

Civil Engineer, Helen Braidwood, talks to us from the Huddersfield Narrow Canal which is joined on both sides by the Standedge Tunnel. The 32km canal is the highest in the UK - 197m above sea level as it passes through the Standedge tunnel. With 74 locks, 10 reservoirs and 5 aqueducts, it can take boats up to 21.3m long and 2.1m wide.

Huge historical mistake at the start. Manchester Ship Canal wasn't begun until 1887, a full 76 years after the Huddersfield was opened.

Where would someone find out more about methods used while tunneling to determine direction and elevation in the 1700s when canal tunnel was built?
Just got done watching a narrowboater's recent video about this tunnel; they mentioned there was some mismatch in direction and height from the 2 ends where digging was being done, and while it is easy to fault the errors, it seems to me remarkable that they were anywhere near close at all.
