Excerpt from A d104-Book of Mining Geology for the Use of Mining Students and Miners The matter in the following pages comprises a series of lectures issued in Bulletin form at the end of 1902. The exhaustion of that little publication has encouraged the author to present the same matter in this revised and enlarged form. The new chapters on Ores and Minerals Considered Economi cally, mine-sampling and Ore - Valuation, and The Examina tion and Valuation of Mines have been added to comply with the requirements of the new curriculum for the associate-diplomas in Mining, Metallurgy, and Geology.
