I gratefully acknowledge indebtedness to Professor Robert Ridgway for counsel and assistance in determining State records; to Dr. A. K. Fisher for records and for comparison of specimens; to Dr. Chas. W. Richmond for confirmation of records; to Messrs. William L. Finley, Herman T. Bohlman, A. W. Anthony, W. H. Wright, Fred. S. Merrill, Warburton Pike, Walter I. Burton, A. Gordon Bowles, and Walter K. Fisher, for the use of photographs; to Messrs. J. M. Edson, D. E. Brown, A. B. Reagan, E. S. Woodcock, and to a score of others beside for hospitality and for assistance afield; to Samuel Rathbun, Prof. E. S. Meany, Prof. O. B. Johnson, Prof. W. T. Shaw, Miss Adelaide Pollock, and Miss Jennie V. Getty, for generous coöperation and courtesies of many sorts; to Francis Kermode, Esq., for use of the Provincial Museum collections, and to Prof. Trevor Kincaid for similar permission in case of the University of Washington collections. My special thanks are due my friend, Prof. Lynds Jones, the proven comrade of many an ornithological cruise, who upon brief notice and at no little sacrifice has prepared the Analytical Key which accompanies this work.

My wife has rendered invaluable service in preparing manuscript for press, and has shared with me the arduous duties of proof-reading. My father, Rev. W. E. Dawson, of Blaine, has gone over most of the manuscript and has offered many highly esteemed suggestions.

To our patrons and subscribers, whose timely and indulgent support has made this enterprise possible, I offer my sincerest thanks. To the trustees of the Occidental Publishing Company I am under a lasting debt of gratitude, in that they have planned and counselled freely, and in that they have so heartily seconded my efforts to make this work as beautiful as possible with the funds at command.

One’s roll of obligations cannot be reckoned complete without some recognition also of the dumb things, the products of stranger hearts and brains, which have faithfully served their uses in this undertaking: my Warner-and-Swasey binoculars (8-power)—I would not undertake to write a bird-book without them; the Graflex camera, which has taken most of the life portraits; the King canvas boat which has made study of the interior lake life possible;—all deserve honorable mention.

Then there is the physical side of the book itself. One cannot reckon up the myriad hands that have wrought upon it, engravers, printers, binders, paper-makers, messengers, even the humble goatherds in far-off Armenia, each for a season giving of his best—out of love, I trust. Brothers, I thank you all!

Of the many shortcomings of this work no one could be more sensible than its author. We should all prefer to spend a life-time writing a book, and having written it, to return and do it over again, somewhat otherwise. But book-making is like matrimony, for better or for worse. There is a finality about it which takes the comfort from one’s muttered declaration, “I could do it better another time.” What I have written I have written. I go now to spend a quiet day—with the birds.

William Leon Dawson.
