Dave,
Below is the gist of my reply direct to Douglas
> Hutton is referred to frequently by Hugh Torrens in his collected papers
published recently as The Practice of British Geology, 1750-1850, and his
work might give you some leads.
>
>As to 'culm' this was anthracite - in south-west Wales it would refer to
small anthracite, less than 1/2 inch in size, and was defined as such for
customs (duty) purposes. In north Devon, it was term used for all
anthracite mined, albeit from very limited crushed horizons in the Lower
Culm Measures (note the use of the term for a whole series of strata in that
area).
