From the Preface: 
N this study I have tried as far 
as possible to see both sides of 
the question. My aim has been to 
avoid the pitfalls of hasty or set no- 
tions. The subject for discussion 
seemed to me to be one of concrete 
fact and not one of personal philos- 
ophy, and therefore I have examined 
some fifteen thousand newspapers 
from all sections of the country as 4 
first means of getting some acquain- 
tance with the necessary facts before 
forming any decided judgments.”
