viii INTRODUCTION 



Perhaps it is to Mr. Wilson above all that ama- 

 teurs are mostly indebted, for his untiring work 

 during the last thirty years in large and long-con- 

 tinued practical trials, and for his unwearied kindness 

 in allowing all who desired instruction to see the 

 results ; also for his generosity in coinmunicating at 

 once to the horticultural press anything about Lilies 

 that he perceived to be of educational value.
