cial appropriation to building an ad-
| dition to the mineral building.
Superintendent Goodwin and his
brother, T. ]. Goodwin, who is his as
sistant, have done the best they could
do with the limited space at their COM
mand. Though there are more speci-
mems to be displayed than last year. on
the whole the display is more attract
i've. But everything has been crowded
almost to the limit. The Goodwin
brothers have themselves done all the
work in connection with the prepara-
ton of the mineral exhibit and one or
both has been constantly in the build
ing since the beginning Of the fair.
The litt' cards which have been put
into the cases to explain the uses of
various rare metals and the character
of the ore are very instructive to the
layman as well as to the professional
mining man. In some of these tiny
placards there is a touch OF dry
humor The cards about the gold
bricks are good illustrations. Scores of
people ask every day if the bricks are
real gold and Mr.. Goodwin's invariable
answer is that they are just what the
cards say they are.
Since the department was opened, at
the first annual fair a big case con-
tributed by the Copper Queen company
for the display of its ores has set in
the middle of the building. This year
the Copper Queen exhibit has been
changed somewhat. The smaller speci-
ments have been replaced by larger
Il; q tI,.,
Copper Queen. Many of the new spe-
cimens are as richly colOred as Belgian
tapestry. II is the aim of Mr. Goodwin
to secure large specimens rather than
small ones. and when the Copper Queen
people saw how much better the big
chunks looked in their case they be-
came enthusiastic. Yesterday morn
ing the superintendent Of the mine told
Mr. Goodwin that he would immediate
ly commence saving ore specimens for
the next territorial fair and that he
would be ready to dispiace all the lit
tie rock This is the first time the
Copper Queen people have taken much
interest in the mineral department, but
they will be Mr.. GOOdwin's enthusiastic
helpers from this time on.
A complete enumeration of the min
erals on display from the various coun
ties would be merely a repetition of
former articles that have appeared in
The Republican, for the fair mineral
exhibit is permanent. but there is a
multitude of new additions that deserve
special mention.
The principal addition to the Mari
copa exhibit is some gold, silver and
Ia ms .
mine i'm the Lidell district This ore
is largely pure copper. with high values
in the two more precious metals it
carries
Copper sulphides, dazzling to the eye
and productive of unbounded enthusi-
asm in one who knows good ore when
he sees it, are there from La Coronado
mine, in Pinal county. Most of the
Coronado ore on display can be regard
ed as samples and not specimens. Prac-
tically all the stock in this mine is
owned in Phoenix and the stockholders |
can see for themselves that there is
no better looking copper ore in the en-
tire department than that from their !
own property.
Remarkable and curious are the |
chunks of silver-lead ore from the o. |
NJ. c. mine, also in Pinal county. The |
ore appears to be almost solid metal.
John Belser of Winkelman, part |
ner of Henry Mitchell of Phoenix, has |
sent down from Winkelman some fine |
of pure white crystalline gyp- |
sum- a mineral used in the manufacture |
Of plasters. Belser's gypsum is as
white as albaster. He has also |
il, no q fif1l
spar, yellow mineral, clear as glass.
Pima county has sent as many new |
specimens as any county in the terri |
tory. There is some unusually fine sill |
ore from the Chesterfield Cop |
per companys property and the Pay |
master group both near Tucson. Some |
copper sulphides from the Mineral Hill |
and Butler mines will run at least 80 |
per cent in the red metal. The sui |
phides from the Twin Buttes are of the |
same character.
No finer polished and unpublished |
granite and marble was ever seen any
where than the specimens which come |
from the Santa Rita mountains, TWEEN
ty-five miles southeast of Tucson. The |
marble is dark in color and takes |
beautiful polish.
Superintendent Goodwin does not |
know to whom he should give credit |
for the woldenite and vanadanite ore !
sent by the Tucson Chamber of Com
merce These metals are found in only |
a few parts of the world and are valu-
able for hardening steel. The ore is |
yellowish brown in color.
Some enormous pieces of schist, |
carrying about per cent copper in |
concentrating form, are fIrm the Miami |
mine. near Globe, one OF the biggest |
copper properties in Arizona. The |
are not snowy but the Miami |
