Production Note 



Cornell University Library produced this volume to replace 

 the irreparably deteriorated original. It was scanned at 600 

 dots per inch resolution and compressed prior to storage 

 using CCITT/ITU Group 4 compression. The digital data 

 were used to create Cornell's replacement volume on paper 

 that meets the ANSI Standard Z39.48-1992. The production 

 of this volume was supported by the United States 

 Department of Education, Higher Education Act, Title II-C. 



Scanned as part of the A. R. Mann Library project to 

 preserve and enhance access to the Core Historical Literature 

 of the Agricultural Sciences. Titles included in this 

 collection are listed in the volumes published by the Cornell 

 University Press in the series The Literature of the 

 Agricultural Sciences, 1991-1996, Wallace C. Olsen, series 

 editor. 



Several pages were scanned an additional time as centerfolds 

 to preserve their center margins. To avoid confusion, the 

 back of the centerfolds were scanned as blanks.
