 PREFACE

T is customary at the close of a Preface to make some acknowledgment of the services rendered by others in the preparation of a volume; but in my case this aid has been so generous, so abundant, and so helpful, that I must reverse the order of things and begin by saying that my heartiest thanks are due to the many who have assisted me in a work which for many years has been my dream.

Without the very material aid, both by pen and advice, of Dr. Elliott Coues, these pages would have lost more than I care to contemplate. All the zoölogical notes are his, and many of the geographical, besides suggestions too numerous to mention; moreover, all this assistance was most liberally given at a time when he personally was more than busy; and yet my wishes and convenience have always been consulted.

Next to the memory of my father, Mr. Ruthven Deane has been the motive power which has caused these volumes to be written. For many years he has urged me to attempt it, and has supplied me with some valuable material, especially regarding Henderson. During the months that I have been working on much that I have felt incompetent to deal with, his encouragement has helped me over many a difficulty.
