At that time Pennsylvania was the only state of all the forty-seven that had met its just obligations to protect all its people under its laws. Pennsylvania's State Police had been for ten years a body of defenders of justice, "without fear and without reproach". The honest people of the State had recorded its deeds in a long memory of noble service. But, never stooping to advertise itself, never hesitating to incur the enmity of evildoers, it had had many traducers and no historian. There was nothing in print to which the people of other states might turn for knowledge of the accomplishment of the sister commonwealth. So, in order that the facts might be conveniently available for every American citizen to study from "A" to "Z" and thus to decide intelligently for himself where he wanted his own state to stand, in the matter of fair and full protection to all people, Miss Mayo went to Pennsylvania and embarked on an exhaustive analysis of the workings of the Pennsylvania State Police Force, viewed from the standpoint of all parts of the community. Ex-President Roosevelt wrote the preface for _Justice To All_, the book in which the fruits of this study were finally embodied, and, in the meantime, Miss Newell devoted all her energies to the development of an active and aggressive state-wide movement for a State Police. _Justice To All_, in this campaign was widely used as a source of authority on which to base the arguments for the case. And in 1917 came Sam Howell's triumph, the passage of the Act creating the Department of New York State Police, now popularly called "the State Troopers". In the course of collecting the material for this book, Miss Mayo gathered a mass of facts much greater than one volume could properly contain. From this she later took fifteen adventurous stories of actual service in the Pennsylvania Force, of which some, including "Israel Drake" appeared in the _Saturday Evening Post_, while others came out simultaneously in the _Atlantic Monthly_ and in the _Outlook_. All were later collected in a volume called _The Standard Bearers_, which met with a very cordial reception by readers and critics. During the latter part of the World War, Miss Mayo was in France investigating the war-work of the Y. M. C. A. Her experiences there furnished material for a book from which advance pages appeared in the _Outlook_ in the form of separate stories, "Billy's Hut," "The Colonel's Lady" and others. The purpose of this book was to determine, as closely as possible, the real values, whatever those might be, of the work actually accomplished by the Overseas Y, and to lay the plain truth without bias or color, before the American people.
