state Analytical Work.

Under an act passed by the state
legislature March IL. lSaS. citizens
nf the state ~ Nevada NAV send ores
and minerals Ia the state university
and have the same analysed and as
saved without cost. In such work,
50 FAR there been determined total
Of 33j specimens and samples, from
ii localities and 2ll individuals or
these, two persons in Tonopah sent
five. The number OF cumulative
determinations made were: Gold,
33l; silver, 3d. copper, 81; lead,l IL;
zine, l. antimony, 3; manganese, 5;
lime, 90; magnesia, IA; silica and in
soluble residues, 81 iron, ferric OK
ide and allumina, So; alumina, i;
moisture and loss by ignition, 81;
mercury, B; tungsten, !; sodium
chloride, ]; sulphur trioxide, Z; sui
phur, g. phosphorie acid, 3; boric
acid, 6; bituminous matter, B; coal
analysis, |. There is nothing in all
this but what the fairly good pros
pector ought to determine for him
self, but the searcher for mineral
values should increasingly investigate
those things of which he does not
know, for which this department of
the university offers opportunity.
The total number of quantitative
determinations have been, 977; of
qualitative determinations, in addi-
ton, &c. rock determinations, 10;
mineral determinations, 81; specific
gravity determinations, 6.
On this subject the University
Bulletin, from which we CLEAN the
foregoing, goes on to say; All gold
and silver assays are made in dupll-
cate and the values determined and
recorded. Reports are made as fol-
lows: where gold value is above s.
per ton--"The gold assay value is
above So per tom where the value
is less than but still in the neighbor-
hood of So per ton-"The gold assay
value is less than So per ton" where
the gold exists in traces only-"Gold
is present in traces only" A SINH
lar form of report is given in the
case of silver and combined gold and
silver values. The state law provides
that returns for gold and silver
should read, "Test for gold, or
''Test for silver" AS the meaning
intended to be conveyed by these
terms is not we'll understood, the
form of report, above described, has
been adopted as fulfilling the inten
tions of the law and at the same time
being more ineligible to the pros
pector or other person receiving the
report. The accuracy of the quaint
tative work is of the same grade as
that for rapid commercial analysis,
and is unchecked unless otherwise
stated. Reports are given stating
per cents. Not all specimens are
analysed quantitatively, as such a
procedure would result in the per-
Torrance of a large amount of UNI
necessary work and the returns
would often be of little value to the
recipient Specimens and samples
are first carefully examined and if,
in the Judgment of the analyst,
quantitative analysis is necessary to
determine the commercial value of
the sample the same is made. In all
cases where the results of a prelim
mary examination are doubtful, a
cumulative analysis is made. No
cumulative determinations ate made
upon small hand specimens, as in al
most all cases such determinations
are misleading unless used for the
purpose of identifying the material.
Reports are rendered upon the com
merciai values are rendered where
ever it is possible to get sufficient
data upon which to base such re-
