g to the placer
mining, which has produced a hundred million dollars' worth of gold in
the history of this region. The Pearl district contributed good
specimens of oxidized quartz and granite gangue, iron and arsenical
pyrites with zinc blend, and a showing of galena and copper sulphides.
Monaxite, a heavy yellow sand, the ore of thorium, is found here, and is
in considerable demand on account of the new discoveries in the radio
activity of certain minerals.

From the vicinity of Pocatello were fine specimens of copper and lead
ores having gold and silver veins, iron, and manganese oxide ores. These
came principally from the workings on Rabbit Creek, Pocatello Creek, and
the Hovey group. Coal specimens were shown from the vicinity of
Blackfoot and Idaho Falls. From Bear Lake County were ores carrying
copper, gold, and silver. Coal specimens were shown from the Goose Creek
Mountains and the ranges in the southern part of Cassia County. The
mines all about Silver City, the county seat and mining center, were
well represented. The South Mountain district, south of Silver City, was
represented by ores from some of the reopened mines which had been idle
for many years.

Ores from the Rocky Bar, Atlanta, Pine Grove, Black Warrior, Neal, Lime
Creek, and Dixie districts made a good representation for Elmore County,
which, on account of its nearness to Boise and railroad facilities, has
been better developed than many other parts of the State. The Yankee
Fork, Loon Creek, and Stanley basin districts of Custer County were all
contributors to the State exhibit of gold and silver ores. The
lead-silver ores of Custer County came from the Bayhorse, Squaw Creek,
Clayton, Poverty Flat, and Slate Creek districts. Copper ores from the
Big Lost River Valley were convincing proof of the richness of mines in
that newly developed part of the State. Fremont County sent specimens of
coal from the rich mines opened a year ago in the eastern part of the
county.

Shoshone County was represented by huge nuggets of lead-silver ore. Gold
ores from Shoshone County showed the wide distribution of the yellow
metal, which appears in every county in the State. Copper ores from
Shoshone County were an indication of future possibilities in copper
production in the State.

It was the earnest endeavor of the Commission to make the most of the
opportunities and the means at their disposal to give Idaho and her
resources a thorough advertisement. The pres
