Abstract
WHEN an author is fortunate enough to have such a godfather for his book as M. Haton de la Goupillière, it may be taken for granted that the work contains much useful matter. The book is intended not so much for the old-time prospector, armed with pick, shovel, and pan, who wanders about in search of gold, as for the scientific mining engineer called upon to report upon a mineral deposit already discovered, and possibly already worked on a small scale; M. Lecomte-Denis tells the novice how to set about his work, and how to draw up his report to his employers, and he points out useful precautions to be observed in purchasing mines and minerals. The motto for the chapter upon “salting,” Défiance est mère de sûreté” is well chosen; many of the common tricks of fraudulent mine-vendors are exposed by the author, who most wisely advises the inspecting engineer to err on the side of scepticism when making his examinations.
