APPENDIX II 

 REFERENCE BOOKS 



The following is a list of books which may be used to supplement 

 the text. An attempt has been made to select a comparatively small 

 number of works which will prove most helpful, copies of some or many 

 of which are likely to be in the school library. With a few exceptions, 

 references to secondary school textbooks have not been included. 

 Copies of various textbooks are sure to be accessible and should be 

 freely used by the teacher ; but their inclusion in any considerable 

 number would have made the present list too long. The same may 

 be said of the bulletins of the United States Department of Agricul- 

 ture and of the various state experiment stations ; a list of the latter 

 is given in Appendix III. Lists of bulletins and circulars may be 

 had from the Superintendent of Documents at Washington and from 

 the directors of the experiment stations. The interest of pupils in 

 the study of particular plants, and in such general topics as lumber- 

 ing, forestry, grafting, plant breeding, and plant diseases, may be 

 greatly stimulated by giving them access to these official publica- 

 tions. Some bulletins which are likely to prove especially helpful have 

 been listed, but they are an inconsiderable fraction of the number that 

 may be used to advantage.
