PREFACE 
Elistory films prepared under the auspices of the 
Selborne Society. I have retained the right per- 
sonally to lecture with the film. 
My readers will realise, as they study this book, 
the great debt of gratitude which I owe, and have 
the pleasure of acknowledging here, to many friends 
who gave me valuable assistance in the course 
of our four years’ campaign. Their names are 
recorded in the daily record of our observations. 
I am under a more specific obligation to Mr. E. E. 
Pettitt for his considerable help in the preparation 
of the manuscript of this book, and to my pub- 
lishers, who have more than lightened the labour 
of seeing it through the press. 
The scientific names of the birds mentioned, 
which I have given for the benefit of foreign 
readers, are in accordance with the nomenclature 
adopted by Howard Saunders in his Manual of 
British Birds , second edition, 1899.
