“This book thoroughly deserves its title of a ‘Practical Treatise.’ The whole process of gold milling, from the breaking of the quartz to the assay of the bullion, is described in clear and orderly narrative and with much, but not too much, fulness of detail.”—Saturday Review.

“The work is a storehouse of information and valuable data, and we strongly recommend it to all professional men engaged in the gold-mining industry.”—Mining Journal.
