viii PREFACE. (who has carried out most of the publication arrangements on behalf of the Club), and to Mr. J. E. Harting (who, beside other help, has kindly supplied the chapter on " Hawks and Hawking in Essex"). I have also to thank many of the professional naturalists throughout the county, especially Mr. Travis of Saffron Walden, Mr. Crick of Chelmsford, Mr. Ambrose of Colchester, his successor in business, Mr. John Pettitt, the late Mr. Scruby of Ongar, and Mr. Stacey of Dunmow. In short, there is scarcely any one in the county, having any pretensions to a knowledge of birds, who has not rendered me cordial assistance. I have also to thank those subscribers (whose names, fol- lowing a somewhat antiquated custom, I have printed at the end of the book) who by kindly ordering copies in advance have relieved me of much of the loss which usually attends the publication of works of this class. The system of references I have used so copiously through the work will, I believe, be found convenient. The numbers enclosed within parentheses refer to the works named in Appendix B, and to the volume (where more than one) and page of the particular work referred to. Where the Field, the Essex County Chronicle, or other newspaper is referred to without the year being given, it is to be understood that the year of the occurrence in question is implied. The word " here," must be understood to mean the district around my home at Chignal St. James, Chelmsford. I shall always be pleased to hear of the occurrence of rare birds, or of anything notable connected with bird-life, in the county, and until the issue of a second edition (if such be called for) it is my intention to record such occurrences in the pages of the Essex Naturalist. MILLER CHRISTY. Chignal St. James, Chelmsford, March, 1890.
