discusses the copper deposits of Utah at
length, and says:
For many years the bulk Of the copper
production has been divided between
Michigan, Montana and Arizona. In
each Of these states the increase has
been rapid and continuous since 1880. but
Cor series of years. beginning with
1891. Montana far exceeded the other two
states. In 1905, for instance. Montana
produced 80 per cent; Michigan, "a per
cent. and Arizona, 1913 per cent Of the

ton. caused by the rapid advance of Ari-
IONA. In 1907. of total of SfO.OOO,OOO
pounds, Arizona yielded 257.0OO,0OO; Mon

pounds. Utah comes next with a produc-
ton OF 100000 pounds. California
yielded $4,000. 600 pounds: Tennessee. TO-
coo 900 pounds: Colorado. 100000
pounds: New Mexico and Idaho. each TO-

'The production of Utah has increased
greatly during the last few years. In
1903 the output was approximately 10000
Sc. 100000 pounds. with prospect of still
further increase. The Utah copper is
mainly derived from the Bingham dis
trct though smaller quantities are OBJ
tanned from the Tintic and Frisco dis
tricts All these ores yield also much
gold and silver, and their extraction Is
therefore to a certain extent Independent
of the price of copper. \ produ. lion OF
about $1,000, GOO pounds could undoubtedly
have been maintained for series OF
years, as new reserves were constantly
discovered. The recent discovery and
utilization OF the low-grade Bingham
prophyry ores, probably the largest SIN
gle body Of COPPER ore nev sne~n advances
Utah still further In the rank OF the cop
per-producing states. The two largest
companies which treat this ore estimate
the aggregate reserves of ore blocked out
which, provided that all of this ore can
be extracted. should yield very large
quantity of copper, besides considerable
amount Of gold and silver. The yield
thus far is somewhat below per cent
copper. The copper can be produced
cheaply: it Is claimed. at cents per
pound. The tonnage to be treated per day
in the plants Of the Utah copper com
pany and the oBston Consohdated Cop-
per Company is over 1900 tons. or 3,15O,-
tOO tons per annum. At this rate the ores
would last thirty-eight years. In addl.

lower but probably workable grades Is

Production Of Lead.

Queer of lead. and the total output now

continued output. and while the experts
say that there is little probability OF an
immediate increase, the present average
will undoubtedly be maintained IN
