mint, a model post office, and features a daily "mine explosion," with a
demonstration of rescue work.

The Palace of Transportation places its emphasis on automobiles and
roads, electric locomotives and cars, and the mammoth types of modern
steam locomotives. All of these exhibits represent construction of the
last year, with one exception. The first Central Pacific locomotive
stands beside a Mallet Articulated engine,--an enormous contrast. One
third of the floor space is filled with steam and electric locomotives
and modern cars. Some are sectioned, and operated by electric motors,
vividly illustrating the latest mechanical devices. Another third of the
palace is devoted to motor cars. The Ford Motor Car Company maintains a
factory exhibit in which a continuous stream of Fords is assembled and
driven away, one every ten minutes.

Plans for a great exhibit of aeroplanes were destroyed by the war. The
Exposition, however, maintains a constant exhibit of the spectacular
side of aeronautics in remarkable flights by famous aviators. After
Lincoln Beachey was killed in one of these performances, his place was

birdman. Two aeroplanes are the only representation in the palace.
Steamship companies have erected here sections of their vessels.
Railroads make interesting exhibits of scenery along their routes, of
safety devices and of railroad accessories. The Canadian Pacific, Grand
Trunk Pacific, Great Northern, Southern Pacific, Union Pacific, and
Santa Fe systems maintain buildings of their own, exhibiting the

The Palace of Varied Industries illustrates the enormous complexity of
