MACKAY SCHOOL OF MINES AT
STATE UNIVERSITY NOW
READY TO DO LABORATORY
ASSAY AND ANALYSIS WORK
FOR CITIZENS OF NEVADA.

fOK Of NbSrtDh.
Under an act passed by the state
legislature, March Is, 1895, citizens
of the state of Nevada may send
ores and minerals to the state uni
versity and have them analysed and
assayed without cost (sections 1902
and 1405, inclusive, compiled laws
of Nevada.) Only citizens of Ne
vada have this privilege and they
may send only such material as
may be taken from within the
boundary lines of the state.
The president of the university
has organized the state mining lab
oratory, a part of the Mackay
School of Mines, to carry On this
work. Professor George j.. Young is
in charge of the laboratory. Under
his direction the work has been
divided in such a way that all as
say and analytical work is done
by Walter s. Palmer, all mineral
and rock determinations are done
by Professor j. c. Jones. A student
assistant prepares samples for assay
and analysis and assists in assay
ing. No determinations are done by
students.
Material submitted to the labora-
tory is classified:
(a) Ore specimens. Single pieces
or several pieces of small size;
Obi Samples. Crushed material,
pulps or a number of pieces of
moderate size.
(e) Rock specimens.
Determinations are either qualita-
tive or quantitative. Qualitative
determination" signifies that the or
binary chemical tests TO identify
metals and compounds have been
used Qualitative determination"
signifies that the proportion by
weight of the metal or compound
in the sample has been found.
This involves the use of gravimetric
and yolumetic methods of an
alysis.
Rocks are determined by the or
binary field methods and when
correspondents desire a determine
ton by thin sections and the mi
croscope they may obtain this by
sending so cents to cover the cost of
the preparation of the thin section.
For most purposes the field method
of determination gives sufficiently
accurate information. Where the
field method, however, does not
give satisfactory results the labora-
tory makes the determination from
a thin section without charge.
All reports are rendered by
letter. approximately ten days is
required from receipt of sample
until report is sent out. In case
that some special investigation is
required, considerable more time
may Ella Sc before the report is sent.
The money available for the work
will not permit the maintenance of
a service throughout the yea and
consequently the following rules
have been made: All material re-
ceived after May 1st is held until
August 10th, and after that date
the necessary examination is made
and the report rendered as soon
as possible. All material on hand
on May 1st is reported upon before
May 10th. All material received
after December 5th is held until
January Sth, at which time the nec-
essary examination is made and re-
ports rendered as soon as possible.
Between the dates of January Sth

December 10th the public will be
given prompt service.
Prospectors and others are ad-
vised to send in ample material
for examination and to avoid send
ing specimens as far as practicable.
II a ledge has been found take
one or more samples by cutting
each across the ledge or take gen.
eral samples by combing a number
of chips taken from many points
along and across the ledge. Mark
each sample or specimen with some
number so that identification may be
easy. The package should be plain
ly marked with name and address
of the sender. A letter giving in
