PREFACE. VII 



Mr. John Isaacs, of the California State Board of Horti- 

 culture and Mr. W. J. Allen, of Bonita, Cal. 



All photographs reproduced in this book, except where 

 otherwise acknowledged, are from negatives belonging to 

 the Florida Agricultural Experiment Station, for permis- 

 sion to use which, thanks are due to Dr. T. H. Taliaferro, 

 director of the Florida Agricultural Experiment Station. 

 Mr. W. S. Hart, of Hawks Park, Fla.; Mr. E. S. Hub- 

 bard, of Federal Point, Fla. ; Mr. G. L. Taber, of Glen St. 

 Mary, Fla., and many others, whose names are not here 

 mentioned, have assisted very materially in many ways. 



The substance of a number of the bulletins of the 

 Florida Agricultural Experiment Station has been used 

 without denoting the source from which it is derived. 



Every effort has been made to eliminate mistakes, but 

 some, doubtless, remain embodied in the work. The au- 

 thor will certainly appreciate it as a favor if any reader 

 noting these will kindly point them out that they may be 

 corrected in future editions.
