PREFACE 
T HE author acknowledges her indebt- 
edness to Henry A. Dreer for 
dates and times of flowering of the vari- 
ous bulbs listed. It is to be understood 
that these dates are only approximate, 
however, as varying conditions hasten or 
retard growth and development in differ- 
ent seasons, and variations of from a few 
days to a fortnight may sometimes occur.
