AUTHORITIES CITED AND ABBREVIATIONS 

 USED. 



In the following list of the authorities which have been consulted 

 in preparing this volume the date of publication cited is that of the 

 copyright rather than that of the title page ; but where no date for 

 the copyright has been found the date of the title page has been 

 accepted as the date of publication. This has been done for histori- 

 cal reasons, as it appears in most cases that the copyright date is 

 a better index of the time when a book was written than the date 

 given on the title page. 



Works issued in series by institutions or by regular organizations, 

 like bulletins and reports of the United States Department of Agri- 

 culture, bulletins and reports of experiment stations, reports of horti- 

 cultural societies and state boards of horticulture and catalogues of 

 nurserymen are not here listed. In referring to such works the 

 citation in each case has been made sufficiently full for the easy 

 identification of the publication.
