ments, along general lines approved by the
commission. The exposition was formally opened on the 30th day of April,
1904, and Wyoming was one of the comparatively few States to have its
exhibit practically complete upon the opening day.

Almost from the opening day of the exposition a surprisingly large
number of people from Wyoming visited the fair, and the expressions of
approval of the showing made by this State were highly encouraging to
the commission. It was shown by registration at the Wyoming headquarters
and at the various hotels that one person in every fifty in Wyoming saw
the World's Fair.

In the Palace of Mines and Metallurgy, Wyoming's exhibits were very
favorably located on two of the most prominent aisles of the building
and occupied a floor space of 2,700 square feet. In addition to this, a
wall space of 2,100 square feet was utilized for a display of Wyoming
pictures, plats, maps, and drawings. The exhibit in this building was
quite extensive and weighed about 250,000 pounds, it being the purpose
of the commission to show all native products in commercial quantities.

The oil exhibit, which Dr. F. Salathe kindly volunteered to prepare,
consisted of over 200 varieties of every grade of lubricating and
illuminating oil in this State, and was one of the most complete
exhibits of the kind shown at St. Louis.

Whenever it was practicable, the commission endeavored not only to show

carrying out this idea, the iron exhibit comprised 32,000 pounds of the
crude ore, and around it were grouped nails, spikes, bolts, steel rails,
barbed wire, and pig iron manufactured from the ore.

To illustrate the utility of our onyx and marble displays, a large
pyramid of the different varieties of onyx, weighing about 40,000
pounds, was shown; also a beautiful mantel and fireplace manufactured
from this material.

The mines exhibit was comprised of 156 varieties of mineral--a larger
number than was shown by any other State--and over 3,000 classified
exhibits. Being one of the most complete in extent and variety shown in
the Mines Building, the State received a gold medal on the general
collective exhibit.

Great quantities of copper ore and copper products from the famous
Encampment district made up a large part of the State's display. One of
the exhibiting companies showed the mineral in all its stages and
processes of manufacture, from the cru
