Review of Copper Handbook.

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 10 proceeding issues, so that
the book is as nearly up-to-date as its
predecessors, and far more bulky
and exhaustive in its treatment of
the manifold phrases of an industry
that is world wide in scope.
The Copper Handbook is encylo-
paedic in scope, but is written
throughout IN plain language, easily
understandable by those lacking a
technical education. The work be-
gins with a 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
densed descriptions Of known copper
deposits of the globe. A glossary
of mining terms,will be found useful
to all readers not thoroughly con-
versant with practical mining, mill
ing 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 alphabet
cally, by titles, rendering it self-in-
dexing, and saving mere than so
pages of double column index that
otherwise would be required to
merely give the titles of the 1925
mines and companies listed in the
book, there being III more titles
than in the preceding annual edi-
ton. The descriptions range in
length from two lines, in the case of
unimportant old aud idle properties
to nearly l6 pages in the case of the
Calumet & Hecla, mine that en-
ploys seven thousand men and will
have paid one hundred million
dollars in dividends by April next.
The detailed descriptions in the
main chapter Of the book are espec-
tally valuable, because of their com
pleteness covering,as they do, exact
titles, full address, details Of organ
ization, officers and finance, in ad-
dition to full and careful particulars
regarding location, area, ores, mine
developement, equipment and pros
poets. Heretofore works Of reference
devoted to mines have confined them
selves either to the financial or The
mining end, but the Copper Hand
book covers all the features of inter
est to investors, miners or scientists,
not of one mine or company, Uut OF
thousands, not in one district, but
in every district in the world y
Investors possessing this book
have at command fund of informa-
tion that not orB will enable them
to form an intelligent opinion OF the
Legitimate copper mining shares,
but which will warn them against
hundreds of the entirely too numer-
Gus class Of mining companies formed
solely to sell stock. The Copper
Handbook may be termed an invest
ment insurance policy to the man
who lacks the costly equipment for
independent investigation that is
maintained by those who have mil
lions invested in mines.
The Copper Handbook is the only
publication in the mining field that
gives ratings to the mines and COM
panies. The good companies are
commended and the fraudulent CON-
panies, of which there are many, are
denounced in plain language. The
reader is not asked to take these
ratings on faith, but the facts on
which such ratings are.based are Civ
en- in detail The accuracy OF the rat
ings is demonstrated by the fact that
OF many libel suits threatened, by
many OF the hundreds Of companies
denounced as fraudulent, not one has
been brought into court.
The publisher makes the usual
offer of sending this book, on q
weeks approval, fully prepaid, to
any address in the world, without
any advance payment. This offer
