Letters Received Tell of Profits
and Give Many Details on

Two letters were received this
morning relative TO Mineral Products,
one touching on the chrome shipments
which have uetted more than was
expected: from R. ]. Pratt. and one
relative TO the manganese QioAide iae-

most comprehensive letter on this

OF chrome ore, which we shipped them
last month. The analysis given by
them ran 1888 per cent, 44.5i per

The alterations TO the digesters.
mentioned in our No. 1876 as being
made, were completed last week, and
the circulation in them is now perfect.
we made trial run yesterday for
the first time, which showed that the
/ chemical reaction works on a large
scale as il did in the laboratory.
The ere which we purchased for
the purpose of making trial run. has
turned out to be entirely different
from our ore. for the reason that it
contains an enormous amount of car
| Donates of lime, ETC. This has caus ed
us considerable trouble in getting
started However, we are now using
| this ore ..:.~ ..z.~. ..>..
Today the plant is operating just
as we expected il would three weeks
ago; the delay in starting being due
to making minor mechanical changes
and to the time required in order to
become familiar with the apparatus.
Eve mentioned in our cable that
improved digesters We're advisable,
BUT it may yet turn out that these will
prove to be perfectly satisfactory
Eve are now going to e"hrtitute
CorrosiroR 1acid-proof) piping for all
the present iron pipe, which change
does not amount to much. We shall
keep on operating as long as possible
with the present piping.
AT present we are making mangan-
csc nitrates from magnesium nitrates,
and have Just been advised by phone
this evening that the plant has ope-
| rated well today on this. AS you
know, the essence of the process is
the making of manganese nitrates.
Once we have made our supply of
manganese nitrates they are used
over and over again. This cannot be
bought in the open market, and there
fore 1t will take little time to make
our supply
''Now that we know that the pro-
cess works on large scale, it is
simply a question of mechanical ma.
nipulation to obtain capacity, economy

factorily and no serious mistakes have
been made. If we were to design it
over again the only important change
would be in the type of digesters.
These are only small portion of the
plant. Even if we should substitute
new ones later on it would be mat.
ter of $4,000 or $4,000 expense.

highly satisfactory and simple* and
