Everything possible has been done to make the volume a guide rather than
merely a general treatise. The chapter groupings are the most obviously
serviceable ones. Running heads will be found at the tops of the pages,
and the sub-headings and catch-titles in each chapter are designed to
make reference. to individual features as easy as possible. A complete
index is added at the end.

Purely destructive criticism and ridicule have been carefully avoided.
But if the writer did not pretend to a power of artistic discrimination
which is lacking in the average layman who has not specialized in art
and architecture, there would be little excuse for preparing the guide.
The praise and criticism alike are such, it is hoped, as will aid the
less practiced eye to see new beauties or to establish sounder standards
of judgment.

Acknowledgment is made to the official Exposition press bureau for
courtesies received, and to those artists who have supplied information
about their own work. For obvious reasons no material has been accepted
direct from articles and books already published. If certain
explanations of the symbolism seem familiar, it is only because all
wordings of the ideas echo the artists' interpretations as given out by
the press bureau.

Acknowledgment is due also to the Cardinell-Vincent Company, official
photographers, since most of the illustrations are from their prints.
