Industrial expositions are a natural development of the fairs of the middle ages. The latter are believed to have originated in the religious gatherings which afforded an opportunity for the sale of wares to large numbers of people. Such fairs still persist in northern Europe, and the best known of them is probably that held three times a year in Leipsic, to which, it is said, "some twenty-five or thirty thousand foreign merchants" are still attracted each year.

In course of time international exhibitions at which specimens of the arts and industries of the great nations of the world were contrasted came into vogue. These began with the International Exhibition held in London in 1851, and of them three have been held in the United States, as follows: The first in New York, in 1853; the second in Philadelphia, in 1876; and the third in Chicago, in 1893. The great magnitude of such expositions has led in recent years to their specialization or subdivision into expositions at which only a specialty was presented. Notable among such have been the following, which were for the most part international: Of articles connected with the leather industry, held in Berlin, in 1877; of all kinds of paper and pasteboard, held in Berlin, in 1878; of fisheries, held in Berlin, in 1880; of electricity, held in Paris, in 1881; of geography, held in Venice, in 1881; of cotton, held in Atlanta, Georgia, in 1881; of early data in American history, held in Madrid, in 1881; of fisheries, held in London, in 1883; of historical matters pertaining to Columbus and the discovery of America, held in Madrid, in 1892; and of hygiene, including chemical, pharmaceutical, and sanitary objects, held in Naples, in 1894.

Similarly there has been a development in the United States from local fairs, such as those of the various mechanics' institutes, typical of which is the one held annually since 1828 in New York city under the auspices of the American Institute, into interstate expositions. Of these, since 1880, the following have been held: Cincinnati Industrial Exposition, Cincinnati, Ohio, September 30 to October 4, 1883; Southern Exposition, Louisville, Kentucky, August 16 to October 25, 1883; World's Industrial and Cotton Centennial Exposition, New Orleans, Louisiana, December 16, 1883, to June 30, 1884; Central Exposition of the Ohio Valley and Central States, Cincinnati, Ohio, July 4 to October 7, 1888; California Midwinter Fair, San Francisco, California, January 1 to July 4, 1894; Cotton States and Industrial Exposition, Atlanta, Georgia, September 18 to December 31, 1895; Tennessee Centennial Exposition, Nashville, Tennessee, May 1 to October 31, 1897; and Trans-Mississippi International Exposition, Omaha, Nebraska, June 1 to November 1, 1898.

Of the foregoing, the more important were those held in New Orleans, in 1884; in San Francisco, in 1894; in Atlanta, in 1895; in Nashville, in 1897, and in Omaha, in 1898; especially so from the fact that all of these received recognition by the Government; and, with the exception of that held in San Francisco, liberal appropriations were made for their support by Congress. Moreover, at each of them, excepting again that held in San Francisco, a special Government building was erected in which the national Government made exhibits of the workings of the several executive departments, together with the Smithsonian Institution and its dependencies and the Fish Commission.

The first named, that of New Orleans, was held as a celebration of the centenary of the cotton industry in the United States. The first record of cotton as a factor in the foreign trade of this country appeared in the shipment in 1784 of six bags, amounting to about one bale, from Charleston, South Carolina. Audubon Park was the site on which the buildings were erected.

The exposition held in San Francisco, in 1894, had for its purpose the affording of an opportunity to foreign exhibitors at the World's Fair to further display their goods in the United States, and in consequence a great number of exhibits were shipped direct from Chicago to the Pacific coast. The exposition was located in Golden Gate Park.

The Atlanta Exposition had its inception in a belief that the agricultural, mineral, and manufacturing resources of the South were not adequately represented in Chicago in 1893. It was believed that a better exhibit of the products of the Southland would tend to foster greater trade relations between that section of our country and other parts of the United States, as well as with foreign countries, especially those to the south, such as Mexico. The Cotton States Exposition was held in Piedmont Park.

The exposition in Nashville was designed primarily to celebrate the one hundredth anniversary of the admission of Tennessee into the Federal Union. Recognizing the commercial and educational advantages to be derived from such a demonstration, it was deemed wise to characterize the celebration as an exhibit of "the matchless resources of Tennessee, and at the same time to lead to their greater development." The old West Side Park was chosen as the site of the "Centennial City."

The exposition held last year in Omaha had for its purposes to do for the Trans-Mississippi States what the more local exhibitions had done for Atlanta and Nashville. It was claimed that it would for the "first time fully illustrate the wealth-producing power and the extent of productive industries of the Greater West," and it did. The exposition grounds were included within what was called the Kountze tract and the old fair grounds.

Each of these expositions has been projected for distinct commercial reasons. They have had for their immediate purposes the presentation of the products of the region in which they were located to their neighbors, to the nation, and to the world. In this sense they have been simply the offspring of the fairs of the middle ages, differing from them only in that the feature of sale has been largely eliminated. That they have been successful in accomplishing the results desired is beyond doubt; indeed, the expositions in Nashville and Omaha were even financial successes. But they have done more than this; they have accomplished a world of good in the way of education.
