vi PREFACE 



In discussing the handling of the individual crops it is assumed 

 that the earlier chapters of the book have already been mastered, 

 and details of numerous operations are not repeated. 



While this book is intended primarily as a text for use in schools 

 and colleges, it is the hope of the author that it may also prove 

 helpful to the ever-increasing number of persons who desire to 

 supply their tables with vegetables from their own gardens, and 

 to persons who contemplate the commercial production of vege- 

 tables as a business. 



The author wishes to acknowledge his indebtedness to the 

 Illinois Agricultural Experiment Station for the use of many 

 negatives in preparing the illustrations, and for permission to use 

 certain material from the publications of this Station. He is 

 also especially grateful to Mr. C. E. Durst for taking the photo- 

 graphs to make the following illustrations: Frontispiece, Figs.
