PREFACE TO THE NEW AND GREATLY 

 ENLARGED EDITION. 



The greatly increased demand for what we have already 

 written on the sweet potato encourages us to use all the 

 means of information within our reach, to add further 

 value to this treatise. We have, through the courtesy 

 of correspondents in the various sweet potato regions, 

 elicited information and views on propagation and cul- 

 ture, which we endorse as eminently practical and useful, 

 uid which will doubtless render this work (the only one 

 published on this subject) indispensable as a book of 

 ,e quick and convenient reference" to all cultivators of 

 the sweet potato. 



lb is not easy to estimate the value of the additional 

 instruction and experience in the a.dded chapters. All 

 needed information, it is believed, is now given which 

 ca,n tend to render this increasing industry more profit- 

 able by means of intelligent culture. 



The modes of culture and management suitable for 

 different sections are somewhat various. This requires 

 attention. For instance, the vines are allowed to take 

 hold on the ridges and produce extra crops in some parts 

 of the South, while in the Northern and Middle States 

 this cannot be permitted without detriment to the crop. 

 The length of the growing season makes this difference. 



Having collected and arranged additional matter that 

 must render our work more useful, we submit it to the 

 public, hoping to merit the increased confidence and ap- 

 proval of all culturists.
