"One of the most valuable works of reference of modern times. Mr. Hunt, as Keeper of Mining Records of the United Kingdom, has had opportunities for such a task not enjoyed by anyone else, and has evidently made the most of them.... The language and style adopted are good, and the treatment of the various subjects laborious, conscientious, and scientific."—Engineering.

"The book is, in fact, a treasure-house of statistical information on mining subjects, and we know of no other work embodying so great a mass of matter of this kind. Were this the only merit of Mr. Hunt's volume, it would be sufficient to render it indispensable in the library of everyone interested in the development of the mining and metallurgical industries of this Country.—Athenæum.

"A mass of Information not elsewhere available, and of the greatest value to those who may be interested in our great mineral industries."—Engineer.
