Both exterior and interior of the building illustrate the amazing progress of the South American republic in art, as its exhibits in the Exposition palaces exemplify its advancement in industry and commerce. The entrance opens into a noble hall, imposing in its simplicity. In the clerestory the walls are decorated with fine murals by the brush of the Argentine artist, Colivadeno,--works which show that Argentine art has the beauty, freshness and vigor of the nation from which it springs. In the center of the hall is an exquisite bit of Sculpture. On left and right the foyer opens into a fine reception hall and a graceful refreshment room. In the rear is a theater, where moving pictures of Argentine scenes are shown daily. In the wall of the corridor surrounding the theater on the first floor are excellent panoramas showing scenery and resources. Among these is a view of the famed Iguazu Falls, the greatest and most magnificent waterfall on the globe. In the corridor upstairs are other panoramas, a series of photographs, and a collection of graphic charts which show the commerce, finance, industry, administration, education and social service of the republic. The second floor ends at the rear in a beautiful library. The pavilion was built entirely of materials brought from Buenos Aires, and constructed by Argentino workmen. Australia.--The Australian Pavilion, at the Presidio entrance to the Exposition, was designed by George J. Oakeshott, F. I. A. N. S. W. (p. 148.) Obviously it is intended to symbolize the industrial cohesion of the six Australian States, New South Wales, Victoria, Queensland, South Australia, West Australia, and Tasmania. The facade bears below the cornice the titles of the states, with the state banner waving from a staff above. All are subordinated to the central tower, floating the flag of the Commonwealth.
