Excerpt from Directory of Illinois Mineral Operators: To Accompany Mineral Industries Map, September 1, 1920 This directory, supplementing the Mineral Industries Map, contains two complete lists of mineral producers, one arranged alphabetically under the class of commodity produced, and another arranged numerically under counties. The alphabetical list comprises the main office address of the companies; the address of plants, pits, mines, quarries, etc.; the means of transportation; and the county and reference numbers corresponding to numbered locations given on the map. The geographical list serves as a cross index when the location, but not the name, is known. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
