IT has been the aim of the compiler of the following Glossary to
bring together all mining terms which have been and are in common
use in the stratified mines in Scotland. No attempt has been made
to include the names of parts of maehincry, and othcr engincering
terms, which, although well-known in Scotland, arc not peculiar to
that country.
The most of the terms are known and used over Scotland;
some arc confined to one or two districts, and a few arc quite local.
Localities have not been indicated throughout, as it would be
impossible to do this accurately in all cases. Neither has it becn
thought desirable to distinguish obsolete names, because some,
although quite obsolete in some districts, arc still lingering, or even
in common usc, in others.
In SOIlle instances a technical word is explained by another tcchnical
word; but the meaning of the latter in plain tcrms will be fonnd
elscwhere.
Thanks arc due to those members of the Mining Institute of
Scotland who kindly co-operated with the writcr in this matter,
and especially to Mr John Gemmell and Mr Jamcs Hamilton, Mining
Engineers.
