From the exterior to the interior is a natural method of progression. Let us therefore pass to a brief consideration of the educational features that are to be derived from an examination, no matter how cursory, of the displays that are to be seen within the buildings. First of all, and indeed frequently the most important, is the exhibit made by the national Government. In the special building devoted to that purpose are shown the exhibits of the several executive departments, including also that of the Smithsonian Institution and its dependencies, and the Fish Commission. As a result of the years of accumulated experience there has been in each of the expositions previously mentioned, except that in San Francisco, a distinct improvement in the installation of the exhibits in the Government Building, until it was recognized in Atlanta that the display was superior to that in Chicago, and in Nashville "the best exhibit ever made" was the verdict of those who had seen the successive expositions previous to that in Omaha. Therefore the telling of a story by means of objects in the best manner possible is the result sought for and attained most perfectly by those who installed the Government exhibits. It is, of course, understood that the purpose of the Government exhibit is to familiarize the public with the methods of carrying on the functions of the different departments. Thus, in the post-office exhibit there is shown the entire sequence of postage stamps, both of the United States and foreign countries, the various kinds of mail bags, figures of the mail carriers in their different uniforms, and finally models or pictures of the methods of transportation. The Treasury Department shows the working of the mint by the striking of commemorative medals, while a full series of the existing medals and coins of the country are displayed in cases on the wall. The functions of the Department of the Interior are shown by exhibits of a series of models of some important invention, as, for instance, a sequence showing the development of the sewing machine. In this way--for of course the blanks and other documents are shown--the working of the Patent Office is demonstrated; while the Geological Survey, also of the Department of the Interior, presents a series of minerals, showing the economical wealth of the country, together with its maps and reports, results of work accomplished. Everything can not be shown, but a most excellent idea of what each department does can be had from a study of the exhibits of the Government.
