PREFACE 



The data for this bulletin are based on the results of four years of work 

 in the trial grounds of the American Gladiolus Society, and on conversa- 

 tions and correspondence with many gladiolus experts. In 19 13 question 

 blanks were mailed to members of the American Gladiolus Society 

 and to some of the growers in Europe. Much information was derived
