PUBLISHER'S NOTE. 



This book has long been in preparation, and the manu- 

 ocript was in the publisher's hands for some months before 

 it was printed. The work embodies not only the results of 

 20 years' studies and experience with the subject, but in its 

 preparation the author has visited nearly every beet-seed 

 farm and similar institution in the world. The Illustrations 

 are mostly from wood engravings originally made for 

 this work.
