hSVICW VI tuC OVppCt uuuuUVOn'
 The sixth annual addition of the Copper Handbook, the only publica- tion devoted exclusively to the cop per industry, has been issued, being several months later than usual in appearance, owing to the sickness of the author last spring, but matter of much later date has been used than in preceding issues issues, so that the predecessors, and far more bulky and exhaustive in its treatment ot the manifold phases ot an industry that is worldwide in scope.
 The Copper Handbook is encyclo- paedIc In scope, but is written throughout in plain language, easily understandable by those lacking a technical education. The work be- gins with chapter on the history of copper, followed by articles on the geology, chemistry, mineralogy, metallurgy and uses of the metal, with eight chapters devoted to con- I copper deposits of the globe. A glossary of mining terms will be found useful to all readers not thor oughly conversant with practical drilling, milling and smelling. The statistics of the copper trade and of
 copper share finances are covered in
 forty pages of highly condensed and
 accurate tables.
 The major portion of the book is
 devoted to chapter describing
 practically all known copper mines
 of the world, and listing every cop
 per mining company of importance.
 This chapter is arranged alphabeti-
 cally, by titles, rendering it self-in-
 pages of double-column index that
 otoerwise would be required to
 merely give the titles of 1926 mines
 and companies listed in the book,
 there being I'll more titles than in
 the preceding annual edition. The
 descriptions range in length from
 two lines, in the case of unimportant old and idle properties to nearly six teen pages in the case of the Calu- , met & Hecla, a mile that employs
 seven thousand men and will have paid one hunded million dollars in
 dividends by April next.
 The detailed descritions in the main chapter of the book are es- pecially valuable because of their completeness, covering, as they do exact titles, full addresses, details o1 organization, officers and finance, ir addition to full and careful particu lars regarding location, area, mine
 development, equipment and pros poets. Heretofore works of refer , ence devoted to mines have confined
 themselves either to the financial ol the mining end, but the Copper Handbook covers all the features O. interest to investors, miners ol
 scientists, not of one mine or com pany, but of thousands, not in ont district, but in every district of tht world.
 To the practical men engaged ir l the work ot making the copper ant now in the gentle art of mining b, prospectus from an eastern office, thu book will be found of great practica value as it gives details promotion U including officers, organization ;. finances, etc., of a sort that usuall, l are hard for the man on the ground y to get at, and a strong side-light i thrown upon many companies, of { kind that may save money to thu practical man who reads the book . It is rarely that one book comprise within it's cover so much information Il on so many different points of inter | est, and all of the sort that botl miner and investor are vitally inter ested in knowing.
 y The publisher makes the annual of fer of sending this book, on a week approval, fully prepaid to any ad dress in the world, without any ad l. vance payment. This offer has bee j. made for six years past.
