INTRODUCTORY 
the contents of this volume are hardly 
more than fragments of the story of my farewell to 
Washington, my work on the Chicago Exposition, my 
slight connection with the University of Chicago 
and my Curatorship in the Field Museum of Natural 
History. The work in the University and in the 
Museum was broken into by the expedition to Yucatan, 
The preparation of my report on this fascinating 
exploration was very absorbing. An adequate idea 
of my work in the ruined cities of Yucatan can be 
had only by reference to my published report, in 
two parts, and unfortunately confined to an edition 
of 1000 copies.
