The evening star and Newark advertiser., 1907-10-11

was made by an engineer who is al
ready satisfied with his financial con-
dition and who would not be likely tc
disturb trade conditions.
In one of his letters Mr.. Ruttmann
explains his silence. 1t is a personal
letter to a Princeton College man who
was a classmate with him in the Co
lumbia School of Mines. Briefly, when
he had penetrated the wildernesses OF
Mexico and found what he sought he
kept his own counsel until he had
made absolutely sure that his efforts
had been successful. He mas gone so
far with the tin project now that the
pig metal will soon be in the market
for sale. Just" as he remarks, "as
q farmer would offer his products"
There will be no stock company ex-
ploitations and no notoriety or pub
LEFTY if MIR. Ruttman can avoid it.
In this letter he says that as there
is no longer any reason for keeping the
secret of his discovery he presumes it
will become public and authorizes the
recipient of the letter to make public
the statement that it will be useless
for others to invade the region in
which he has prospected, as he has
held the secret until he could arrange
so there would be no competitors dig
ging into his veins or starting litiga-
tions or doing other things that have
at times made mining a source of
trouble in Montana. and other mining
States.
Mexican miners get 81 a day, or 50
cents American money, which will
hardly tempt residents of the United
States. There is practically nothing
else in the Durango wilderness for
Americans, who are good at anything,
and he feels that this fact ought to
be made prominent in anything that
may be published about his discovery
This is an extract from one of the
new tin millionaire's letters:
MY long tour of engineering duty
does not seem to have been without
result. As you know, I came to Mexico
to find gold and silver, but 1 have dis
covered something quite as good in a
way. Outside of Alaska, which is only
accessible part of the year, there is no
tin produced in the United States. One
of the mineral properties which l have
discovered yields on assay from 20 to
40 per cent. metallic tin, while the
average ore from Cornwall is only
per cent, and that is one of the chief
sources of supply for the American tin
plate industry. Some pieces of ore
have assayed as high as 60 per cent,
but the lowest is so much higher than
other mines produce than this one is
a bonanza.
1T may interest you to know that
the ore occurs as cassiterite, and the
rare mineral durangite is quite
plentiful in the ore. Free gold and sill
yer are found in the ore, which is taken
from granitoid rock composed chiefly
of quartz and pink-colored feldspar
Topaz also is found associated with
the ore, significant fact. At the To-
cation of this mine the igneous over
flow has been eroded, laying bare the
outcrop of the granite.
"On either side of this property the
trachyte and diorite rock rises in pre-
cipitous cliffs for hundreds of feet,
showing the depth to which the granite
is covered at this point, or, to make it
palmer to you, except for the denuda-
tion of the everything igneous rock at
this point this exceptional deposit
might have remained undiscovered for
centuries to come"
