NOTE OF ACKNOWLEDGMENT 
HILE, in the preparation of this work, I have 
met with universal kindness from the ever- 
hospitable Californians, my especial thanks are due 
to members of the Cooper Club and to Dr. David Starr 
Jordan, of Leland Stanford University, for many cour- 
tesies extended and kindly encouragement given. For 
advice and assistance I am also indebted to Mr. Chas. 
F. Lummis, Mr. Leverett M. Loomis, Mr. John Muir, 
Mr. Joseph Grinnell, Mr. H. R. Taylor, and the late 
Chester A. Barlow. But it is to my fellow-student 
and co-laborer, my husband, Mr. Harry B. Wheelock, 
that I owe most. With untiring patience he has 
read manuscript, checked lists, and corrected errors, 
thereby making it possible for me to go on in the 
face of many obstacles.
