 Library. 



A computer search with CAIN-ON-LINE (Cataloging and Indexing) 

 at the National Agricultural Library was made as a cross check. This 

 relatively new source, which is compiled from Bibliography of Agricul- 

 ture, contributed no additional titles. The authors wish to thank the 

 library for making available this computer service. 



Contents. The titles are grouped for convenient use under nine 

 headings named in Contents and designated by letter (A-J). Listing is 

 alphabetical by author. 



Cross references at headings of lists have been inserted as needed, for 

 example, where a publication covers two States. References limited to 

 the cultivated plants or to a plant family in one State generally are listed 

 under the name of that State with a cross reference. 



The tenth heading is: J. Special Lists (Cross References). It contains 

 no new titles but has cross references to some under other headings. The 

 Index to Authors (page 50) cites year and letter of heading.
