American MID from N j. Franknite bar iron ID II 600
This test shows that the iron manufactured from Frank
Unite is the strongest article Of the kind known and
it must command ready SALE at high prices for chain
cables railway axles and all other purposes where great
strength is required The question with manufacturers
quality and the price of little consequence in compar
son. In trial in casting water pipes by mixing por-
ton of Franknite with bog ores found that in al
tempting to break the castings the sedge hammer made
quite ndentation in the casting before it broke show

from bar about inch square, and accurately gagged
required weight equal to n 900 lbs per square inch

which indicates the results with the greatest precision
An immense number Of experiments have been made

but upon he best irons of England Sweden Spain and

county New Jergey and nowhere else in the world As
interesting and conclusive these experiments appear,
Learn that in the of few days, Developments
will be made that will without doubt, astonish the iron
manufacturers of every country It is undoubtedly true
that cheaper and qualities Of iron can be anuac
tured abroad imported into this country and sold at
prices below what manufacturers afford but for
all purposes where superior article is required iron
manufactured from the Frankline must monopose the

consequence Of the poor quality OF the iron used If that
lie the only ii is in fair way being removed
As soon arrangements have been perfected for
featuring iron from the Frankintc shall have the
best article in the world at prices comparatively moderate
Millions upon millions of dollars have been paid annually
for mportaons Of iron for railways and for oil other
purposes, while have had, within few miles of this
city, the most valuable and extensive mines Of most
superior ore untouched, and, until within a few years
unknown. Tho time has however, arrived for the
most rapid development of the mineral wealth of this
country Capital Is cheap and abundant and it cannot
be prohtably employed than in thoroughly work
ing the numerous valuable mines which arc known to
contain inexhanstblc quantities Of the richest ores.
Great Britain has become the wealthiet and most pow
crfu commercial country in the world directly through
the products Of her mines and there why
should not mmeasurably eclipse her through the
agency OF all minerals iron the most valuable for
all practical purposes Gold is nothing compared with it.
Before the lapse Of many years the mining interest Of the
United States will without doubt be greater than any
other and those who the pioneers in the movement
will reap the richest harvest.
