FIG. 3. THE CORLISS ENGINE AT THE CENTENNIAL EXHIBITION, 1876. This vast steam engine, designed without any concessions to contemporary notions of ornament and decoration, was the dominant feature of the exhibits in Machinery Hall. This picture, never before reproduced, is taken from a chromo-lithograph published in Treasures of Art, Industry and Manufacture Represented in the American Centennial Exhibition at Philadelphia, 1876, Buffalo, New York, 1877.
