London: The Mining Magazine, 1912. First Edition. Association copy SIGNED and INSCRIBED on free front end paper by the future President and his wife, "To Chester Benson / With Kind Regards of / Herbert Hoover / Lou Henry Hoover". Interesting association copy between two Oregonians and at the time, two titans of commerce. Stamped number 01930 out of 3000. 8.25" x 13.5"  xxxi 1-640 with scores of woodcuts, tables and instructions about the methodology of mineralogy throughout the ancient practices in the ancient world. Still bound in the original vellum, the bottom couple inches of the spine appears to have once been nibbled by mice in the basement of the Benson Hotel, expertly reconstructed.
Chester Benson was the third son of Simon Benson, timber and land magnate whom Gov. Withycomb designated as "Oregon's First Citizen". The Hoovers frequently stayed at the Benson Hotel when visiting his home state of Oregon. Very Good to Fine. Item #82
"There are three objectives in translation of works of this character: to give faithful, literal translation of the author's statement; to give these in a manner which will interest the reader: and to preserve, so far as is possible, the style of the original text. The task has been double difficult in this work because, in using Latin, the author availed himself of a medium which had ceased to expand a thousand years before his subject had in many particulars come into being; in consequence he was in difficulties with a large number of ideas for which there were no corresponding words in the vocabulary at his command...he coined several hundred Latin expressions to answer his needs."
