THE PEARS OF NEW YORK 589 



BIBLIOGRAPHY AND REFERENCES, WITH ABBREVIATIONS USED 



The list of books which follows contains all American pomological 

 works in which the pear is discussed at any length. Only such European 

 books are listed, however, as were found useful in writing The Pears of 

 New York. Only periodicals are listed to which references are made in the 

 text of the book. The reports and bulletins of experiment stations and 

 horticultural societies are not included since the abbreviations used for 

 such publications will be recognized by all. The date of copyright has 

 been preferred to that of publication, though sometimes it has been 

 necessary to use the latter, as when there were several editions from the 

 same copyright.
