promise IN year or two to amply reward the cap-
tai ard labor expended upon them. in some cases
srsvorable locations have been made but in large
majority OF cases the explorations OF the miners
have exhibited results fully answering their expecta
lions. Pittsburgh and Boston appear to be head
quarters Of copper information, and we condense
rom The Boston Post the substance OF various let
tiers received at Boston, from Lake Superior, to
which We add some information obtained from other
sources The Post says:
In the Cliff mine alone. Boston stockholders are
interested to TIE amount of $3.50 000 at the present
market price Of the shares, and Is not too much 10

of the eighteen or twenty other mining companies
that ere in various stages Of development, is held IN

The Cliff Mine of course demands the first notice
S. w. Hill ESQ, agent of the Copper Falls Nine,
writes.
"It would have seemed almost foolish TO state
within the last eighteen months that the Ciif Mine

richer But il is certainly much better than be-

OF the "Adventure" mine, A. Coburn, Esq., treas.
urer of the Farm" writes:
1.-THE Adventure mine is producing considerable
copper, and Captain Moyle tthe superintendent
says he will send down 30 to 40 tuns In the spring.
The same gentleman says:
1.-THE Forrest" mine is looking well there are
probably six tuns of copper raised Some of it is in
large masses. The prospects are better than ever
saw them before. The company has fine saw mill
and stamps. Mr.. Sales has found great deal OF
copper, there being several masses Of 600 to 800
pounds"
OF the Shirley mine, the writer says:
eve have reached the vein in the long adis. 1t
10 from five to six feet thick, composed Of quartz,
spar and epldote, charged with very fine copper"
OF other promising locations Mr.. Coburn says:
"Mr. Wilson, agent of our mine, (the FARM is
pushing the work on the Farm, Toltec and Algomah
With great energy and reduced prices. We shall
have supplies sufficient to last till next fall The
vein. in the Farm and Toltec, looks very well"
The same gentleman says:
WThe Minnesota is producing from forty to Fifty
rns of copper per month"
The Phoenix Mine has been very successful Of late.
| Joseph PAUL, agent OF the "North American
| writes of the Phoenix:
1.-THE mine is improving. The vein in the first
level is from two TO two and half feet wide, very
| rich stamp work with some barrel copper. In the
| drift, sixty feet below this, driving south from
winze the vein is from ten to twelve inches thick
also very rich"
| OF the cooper Falls" the superintendent says:
"Our mine is now looking much better than ever
| before. The vein in No shaft is twenty inches
wide and produces excellent stamp work In the
upper adt the mine is good. Considerable barrel
work has been taken from that part Of tho work to-
day. Some sheets of copper met with there.
The west vein Is yielding some pure copper and
mixed rock and copper equal In richness to tho besi
vein in the country. Our mixed rock and copper Is
about per cent. of the latter.
"In the shaft, the vein is, in the north end over
two feet, and in the south about twenty inches thick
In the adit We have good vein, with copper In
bunches and disseminated through the vein rock'
The Copper Falls has expended great deal OF
money in time past, and without much success.
But the new vein decided and rich, that 1t Is
now regarded as among the very best of the less de-
| We ioped mires.
The North Western Mine Is managed and owned
! principally in Pittsburgh and Detroit. There are
fifty men engaged in this mine, which is rich in all
| its parts with small mass, Dbl and stamp "copper"
and is opened in the most advantageous manner for
extensive working The engine is all ready for ship
msnt as soon as navigation opens.

out some masses from 800 to 200 pounds each-a
very promising trade. Here the water power ma.

EThis mine 10 nearest the Lake shore, and has the
easiest access to its harbor OF any mine the Lake
The North American has struck the rock at the
depth of SO feet in sinking the shaft, what is
called the South Cliff.
The Adventure has continued to improve very
rapidly oflate. They have number ofhne masses,
and expect to ship 80 tuns tho opening of navisa

The Ridge has been placed under new manager
and mining agent, and is said to be opening very
finely. The new agent has the highest opinion of
the mine.
This Company own l,29S acres of land, and have
mineral rights ON 200 more They employ at present
90 persons and have all the necessary works for
raising and smelling ore. They produce about two
tuns lead per day. and have capacity for three tuns
at cost of about $50 per tun On the 10th inst the
workmen commenced drifting between the shafts
calculation has been made the basis OF the pres
ent Weld that there is 1--WE millions dollars
worth OF lead between the two shafts.

"The Northwest Mining Company ranks next in
value TO the Chff.) Mining was mere commenced in

In 1919 the net proceeds from the sale of copper
amounted to some 5000 In 1880 TO about e32 900
and in 1851 to something over $4,000. This COM
