PERHAPS THE MOST INTERESTING AND CER- 



tainly the most pleasing aspect of the preparation of this 

 book was the generous response which we received from 

 <<]; those whom we asked for assistance. Dr. George B. Rigg, 

 authority on bogs and marshes, checked parts of the manu- 

 script and supplied valuable information. Mr. and Mrs. 

 \ George A. Leis of the University canoehouse continually 

 ^advised us of changes in the area. We express our thanks to 

 Dr. Erna Gunther, Executive Officer of the Department of 

 Anthropology, University of Washington; Dr. Victor B. 

 Scheffer, Biologist of the U.S. Fish and Wildlife Service; 

 Dr. Alexander B. Wetmore, Secretary of the Smithsonian 

 . Institution; Mrs. Martha R. Flahaut, Curator of Biology, 

 Washington State Museum; and Malcolm T. Jollie, Depart- 

 ment of Biological Sciences, University of Idaho. We have 

 benefitted from the experiences of other students of Union 

 Bay, especially Professor Elizabeth L. Curtis, University of 

 Washington; Dr. Robert C. Miller, Director of the California 

 Academy of Sciences; Warren Flock, Walter Hagenstein, 

 ,-and the late Samuel F. Rathbun. J. Ronald Todd, of the
