PREFACE: The republication of the papers and consequent discussion upon sampling of ore in mines and the estimation of the tonnage available needs no apology; it is a subject of the utmost practical importance. It is safe to say that the reputation of mining engineers has suffered more from the neglect of this branch of practice than from any other cause......Originally published in 1903, this early works contains much information that is still useful and practical today. Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
