FOREWORD 



This bibliography was designed to bring together the more important 

 references to publications relating directly to western grazing lands, 

 the domestic livestock and wildlife produced thereon, and the manage- 

 ment of these lands, livestock and wildlife in the 17 "Western States 

 and Alaska, which comprise the range country, excluding eastern 

 Texas and eastern Oklahoma. Published reports on work in other 

 regions, especially the eastern part of the United States, have not 

 been included unless applicable to western range problems. Only 

 those local publications of real value have been included; abstracts, 

 brief general notes, obsolete bulletins, mimeographed material, 

 indefinite preliminary reports, etc., have been excluded insofar as 

 possible, unless they contain a definite, valuable piece of information. 

 Publications on hogs and dairy cattle have not been retained because 

 of their minor importance on western ranges. Foreign references, 

 other than those especially important Canadian and English publica- 

 tions which deal with our western range problems, have been excluded 

 except in the case of a few references of very great general value. An 

 explanatory note has been appended to each such foreign reference 

 which has been included. The bibliography is believed to be reason- 

 ably complete through 1933 for the publications of the Federal Gov- 

 ernment, the State agricultural experiment stations, articles in the 

 more important popular magazines and scientific journals, and text 

 and other books. Some of the more important references published 

 from 1934 to 1937 have also been included. 



In general, the headings indicate the character of the references 

 included in each section. However, to facilitate the location of 

 border-line references, each heading has been distinctly defined as to 

 the scope of material included therein. Cross references are listed at 

 the end of each section. 



The classification scheme used in this bibliography is a revision and 

 amplification of C. L. Forsling's grazing section of A Classification of 

 Forestry Literature, published in the Journal of Forestry, February 

 1923. The main headings of this revised scheme were first published 

 in 1926 as a part of the Extension Service Handbook on Agriculture 

 and Home Economics. 



Titles of periodicals are abbreviated according to the list in Depart- 

 ment Bulletin 1330, Abbreviations Employed in Experiment Station 

 Record for Titles of Periodicals, published in 1925. 



The author wishes to thank those members of other bureaus in the 

 Department of Agriculture who reviewed and offered many helpful 

 suggestions on certain sections. Grateful acknowledgment is made 

 to those members of the Forest Service who gave valuable assistance 

 in the preparation of the manuscript, particularly to W. R. Chapline, 

 Chief of the Division of Range Research, whose continuous advice 

 and suggestions, especially as to organization and selection of material, 

 were invaluable. Acknowledgment is also due to tbe late Mrs. Vir- 

 ginia Gassaway and to Miss Margaret F. Call for their very consider- 

 able assistance.
