= New York, April 2s-The London cor
respondent of the Herald sends the fol-
lowing cabiegram to his newspaper:
Senator Ciark's visit To Europe Is likely
10 confirm his claim TO the title OF Cop
per King I'm a way that he did not am
ticipaie when he set out To round up
the Rio Tinto mine into the new ANAL
samation. When he returns 10 America
not only will he be In position 90 dis
regard the opposition OF the Calumet and
Hecla mine. but he will be able to die
tate terms TO every copper foundry in
the United States. If n deal which 1
heard of yesterday goes through,
This deal means the acquisition by
the Montana Senator OF "A newly discov-
cred process by which bars, sheets and
tubes can be manufactured from the
crude material almost at the pits mouth.
This will mean a saving Of something
like eco (si0o) per ton on the finished
material.
The process Is electrolytic and is close
~ analogous TO the electrolytic refining
method by which two hundred thousand
tons OF copper were refined In the United
States last year The new process uses
the same amount of electrical energy
per ton OF metal as the old. but is worked
eat rate ten times greater, and In maxi
ing bar copper for subsequent melting
a rate 20 times greater is said to have
been successfully used.
The manufacture of copper articles di-
rect from the crude metal has long en-
gagged the attention of inventors. i'm
view OF the enormous profits accruing.
Many attempts have been made but
hitherto all alike have been unsuccess-
fni or only partially successful. The
new process is said not only to over
come the known difficulties. but by an
ingenious contrivance, automatic In its
action. Ia have effected a marvellous
Improvement over all methods hereto
fore known
Mr. David Cook. an electrical eug-
neer. who carried out the lighting Of the
city OF London. gave me some important
data regarding the process, which, he
says. will reyolutiouize the copper i'm
dustry. II had some tubes made by this
process" he said. which stood test
up to 5000 pounds per square inch without
showing Il sign OF weakness, the ordi-
nary test being 600 pounds. To show how
n would work. say I'm the Anaconda
mine. where 1000 tons OF copper are elec-
troiyticaliv refined daily in 1900 vsus COW
eriug something like e5 acres Of ground,
only 100 vats would be required by the
new process
Where. under present conditions. the
product requires 20 go subsequently
through the processes OF smelling. draw
ing. forging. and rolling before the i'm
ished article is produced the new pro-
ccss Will produce the finished article
direct from the vat. This means the
saving OF from sio0 To $500 per ton COM
pared with the present method. I'm fact
the new process practically abolishcs
copper manufacturing as at present un-
derstood."
Messrs Stangor and Blount. govern
ment analysts have been making tests
of the new process in their laborato
mt Westminster. The results OF their
test we're given me yesterday.
These show that copper can be dcpos-
sted as coherent sheet at n current den
city ten times greater tisrT that employ
ed In ordinary eiectro-deposition. The
