A crosscut was till lately driving north from Blue Jock Level (K) but the 2 men employed there are now assisting the mason at the arching.


A note concerning measurements

Measurements in the mines were generally done by two methods; Chains & Links or Fathoms

A Chain is 22 yards (or 66 feet) and there are 100 Links to a Chain, this makes a Link 7.92 inches.
A fathom, as in nautical terms, is 6 feet.

The surveyer here quotes both measurements, frequently using abbreviations:

• fa - Fathom
• l - Link
• c - Chain

A common surveyor's chain, in England, Gunter's chain, has 100 strong 'links' of wire connected by iron rings, with brass handles at the two ends. Intermediate points are marked by small brass tags at 10 link intervals. The usual length of Gunter's chain is 22 yards ie 66 feet, and measurements are made in chains and decimal parts which might be expressed in links; 3.34 chains = 3 chains 34 links. A link is 7.92 inches.

The chain is a decimal instrument, 1/100th chain is 1 link. The chain was introduced by Edmund Gunter, b1581 d1626, mathematician, who is also credited with the introduction of the decimal separator to mathematical notation.
