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 In- 

 dustrial 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 Ex-

 with the exception of that held in San Francisco, liberal appropria- 

 tions were made for their support by Congress. Moreover, at each 

 of them, excepting again that held in San Francisco, a special Govern-

 exhibits of the workings of the several executive departments, to-

 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
