Abstract
THE technology of the non-metallic minerals has not before been treated so systematically and comprehensively as in this book. Merrill's well-known book is essentially geological and mineralogical, but Mr. Ladoo gives us not only the physical properties and mode of occurrence, but also methods of mining, uses, and market values, together with much miscellaneous commercial information. The materials discussed are listed under nearly ninety headings, arranged in alphabetical order, and to each section a bibliography is appended. The volume closes with a more general bibliography and an excellent index, so that as a work of reference it is both a valuable compilation and an admirable guide to a literature that is comparatively little known.
