The prominent position of the state Of
Utah among the copper producing states
OF the union is very clearly set forth
by Horace J. Stevens In this Copper
Handbook for l9Io.le1l. in which is con
tained an extensive and detailed dcscrip-
tion of the Utah Copper company and its
property Of Bingham, the proposition
which has given C;ah !ts prominence as
copper commonwealth In part Mr.
Stevens says:
"The Utah Copper company has the
largest developed ore body In the world
It's proven tonnage exceeding that ol the
Rio Tlnto, its nearest copper competitor,
and even exceeding the proven tonnage
OF the greatest of tho enormous iron
mines of the Mesaba range, and exceed
Ing the developed tonnage OF gold orc oi
all the combined mines OF The WltWaters-
rand Not only has the Utah copper
company the largest body of developed
ore OF any mine. but it also is. AT pres

How Mine Developed.
''The mine has been developed by very
extensive underground workings. and by
churn and diamond drill boring. The ag-
gregate length OF all underground OPEN
incs In the Utah and Boston mines was
63Is miles to December 81 1910. but
nearly n third Of these workings had been
destroyed by opencast operations on the
Utah group. and by underground mining
on both groups. a total OF 2o.l3 miles oi
underground openings having been eNca-
waited. leaving accessible, in both groups.

Question of Costs.
In closing his article, Mr. Stevens says
The estimated average cost of { cents

Utah Copper has not reached. and cannot
reach, the eXtrepe low cost originally
predicted By the management, IL has
fully demonstrated It's ability TO make
copper in enormous quantities Mt an av-
erage cost well under 10 cents per pound,
and is making copper at somewhat
lower average cost than the average cost
of the ten largest producers Of the world.

Position Of the State.
AS for the state Of Utah as a whole
Mr.. Stevens says:
This state. while now ranking fourth
in point OF production among American
commemorative. is scarcely second to
any in promise. and possesses in one Of
its camps the largest bodies of ore OF any
metal known anywhere upon the globe
The copper production is increasing rap
idly, and in 1906. the copper output OF
Utah was about as great as the produc-
tion OF either Michigan or Montana IN
1887, and about as large as the output
Of Arizona In 1897. The state has cop
