strictly observed save in rare cases where older forms have been
admitted for comparison. The result is two-fold. The exhibits are
condensed to the essential, giving room for a greater number of
exhibitors; and the progress of the world is shown as of today.

Eleven palaces house the exhibits, exclusive of live stock. Officially,
the things shown in the state and foreign buildings are not "exhibits,"
but "displays," and are not eligible for award. In general, the names of
the palaces indicate the classes of exhibits to be found in them. No
sharp line, however, can be drawn between the Palaces of Manufactures
and Varied Industries, or between Agriculture and Food Products. In
other cases there is some overlapping of classes. One section of the
Liberal Arts exhibit is in the Palace of Machinery.

A striking feature of almost all the palaces, and one that
differentiates this Exposition from its great predecessors of a decade
or more ago, is the common use of the moving-picture machine as the
fastest and most vivid method of displaying human activities and
scenery. Everywhere it is showing industrial processes. Former
expositions, for want of this device, have been mainly exhibitions of
products. These have hitherto been shown in such bulk as to fill vast
floor spaces and become a weariness to the flesh, while it was
impossible, from the nature of things, to exhibit the great primary
industries of field, forest, sea and mine in actual operation. The
motion-picture machine has not only lessened the areas of products
shown, thus making this Exposition more compact than former ones; but it
has increased the effectiveness of exhibition methods by carrying the
spectator, figuratively, into the midst of operations, and showing him
men at work in all the important processes of agriculture, in the
logging camps, in mines and fisheries, as well as in the mills and
