APPENDIX B 



Supplementary Readings 



When using encyclopedias or other general reference books or textbooks, 

 it is helpful in each case to locate the parts that are of special interest by means 

 of the table of contents or of the index. For each unit of this text, several 

 special books are listed in the pages following. In addition, some of the more 

 general sources of interesting reading matter are suggested. Most of the 

 items are listed under their authors' names, which are arranged alphabetically; 

 the most important book for a particular reader may appear at the very end 

 of the list. Many of the books are not too specialized, and contain material 

 of interest in connection with topics in two or more units. Each book is 

 listed only once, however; and it is hoped that the reader will discover the 

 resources of each book for later use. 



Each agricultural experiment station and the extension division of each 

 state university or college of agriculture in the several states publish useful 

 bulletins and pamphlets. 



The United States Department of Agriculture will send lists of Farmers 

 Bulletins and other biological publications. 



The Superintendent of Documents, Government Printing Office, Wash- 

 ington, D.C., issues free lists of government pamphlets on forestry, plants, 

 health, children, birds, wild animals, food and other subjects. 



College textbooks on agricujtuje, biology, botany, hygiene, physiology, 

 zoology and so on make useful reference books. 



Yearbooks of the Department of Agriculture and the annual reports of 

 the Smithsonian Institution can usually be obtained through the Congressman. 



Books on natural history, exploration, geography and biography often con- 

 tain material that is interesting to the student of biology.
