The mineral exhibit occupied 1,020 square feet in the Palace of Mines and Metallurgy.  Here were shown 186 exhibits of sandstone, limestone, and other building stone, magnetite, brick (both burned and green), transparent selenite, and various others from Oklahoma.  It also contained salt, oil, and glass sand testing 96 per cent pure.  The plaster resources of Oklahoma were shown from the raw material in a solid block weighing 3,600 pounds, through the various evolutions of plaster manufacture to the finished product in dainty statuettes.  A prominent feature of this exhibit was the relief map of the Territory, made from Oklahoma plaster by Doctor Finney, of the University of Oklahoma.  The map weighed 1,600 pounds and showed every elevation and depression, with the rivers, streams, lakes, gypsum deposits, and salt reserves.  The total cost of collection, installation, and maintenance was $3,263.50.

The legislature of the State of Oregon made an appropriation of $50,000 for the participation of Oregon at the Louisiana Purchase Exposition.  One of the main objects was to excite interest in the Lewis and Clark Centennial Exposition to be held at Portland, Oreg., in 1905.

The Oregon State Building was built of logs and was a reproduction of Fort Clatsop, the fort in which Lewis and Clark and their companions resided during their stay in Oregon in the winter of 1805-6.  Two square wings stood diagonally from each front corner of the building like the old fortress abutments used in the days when it was necessary for pioneer settlers to maintain such defenses against the hostile Indians.

The cost of the erection and maintenance of the building was $9,000, of which the Lewis and Clark Exposition Company contributed $3,500.

Not including the exhibits in the Oregon Building, the State made exhibits in six exhibit palaces, as follows:  Agricultural Pavilion, Horticultural Pavilion, Educational Pavilion, Forestry Pavilion, Mining Pavilion, and Fish and Game Pavilion.

In the Educational Department a very interesting display was made by the State board of education and the public schools of approximately all the towns in the State.

In the Forestry, Fish, and Game Building were exhibits by large lumber corporations of the State and a very interesting display of mounted specimens of fish and game, furs and rugs, also cannery displays from the fish-canning concerns.  The Oregon State experimental stations at Corvallis and Union made very interesting exhibits of grains and grasses in the Palace of Agriculture.  The same classes of products were exhibited by about 60 individual exhibitors, residents of the State of Oregon.  While grains and grasses formed the largest exhibit, there were also interesting displays of wool, mohair, hops, milling stuffs, evaporated cream, and vegetables and fruit, both evaporated and in jars.
