DOWNLOAD EBOOK →Excerpt from A Glossary of the Mining and Mineral Industry Because the demand for this glossary has been mounting steadily to the point where urgency is indicated, the Bureau of Mines has decided to republish the volume, which has been out of print for many years because the plates wore out from frequent use. In reprinting Fay's original work, it is recognized that new terms and expressions have come into the language; new usages have been applied to some of the old terms; and some of theold terms have become obsolete. The Bureau, therefore, will welcome and appreciate suggestions and comments from users of the glossary with respect to changes in definitions and explanations, as well as the inclusion of new words and phrases. It is hoped that, with their help, a new, revised, and improved glossary can be published at an early date.
