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 machinery, and other engineering terms, which, although well-known in Scotland, are not peculiar to that country.
The most of the terms are known and used over Scotland; some are confined to one or two districts, and a few are quite local. Localities have not been indicated throughout, as it would be impossible to do this accurately in all cases. Neither has it been thought desirable to distinguish obsolete names, because some, although quite obsolete in some districts, are still lingering, or even in common use, in others.
In some instances a technical word is explained by another technical word; but the meaning of the latter in plain terms will be found elsewhere.
Thanks are due to those members of the Mining Institute of Scotland who kindly co-operated with the writer in this matter, and especially to Mr John Gemmell and Mr James Hamilton, Mining Engineers.
