We shouldn't get hung up over seam names representing the true thickness
- The Swansea Four foot (for example) could easily have been 3ft thick
(or 5ft for that matter) at a particular location - and consequently may
well have been called the "3 feet", "3 foot" or "Yard" on a local basis
- until such time (mid 18th Century?) as the stratigraphers tied up the
seam names from colliery to colliery based on the marine bands.

Hello Alwyn
Thabnks for yourd etailed reply and sorry for the delay in replying --
been
away for a week and just catching up.
Many thanks for all your suggestions. The Llanerch slant is a mid-19C
slant,
but presumably in much the same area as the 18C level which "came to the
yard" at Llanerch. What I was really trying to establish was what the
phrase
"came to the yard" means, but nobody seems to have come across it. The
most
convincing suggestion is that "yard" is simply the area riound the levl
mouth, so "come to the yard" means "reached the surface". There is a
Three
Feet seam in the lower Swansea valley but I don't think it was ever
called
the Yard Seam, always the Three Feet.
