Book excerpt: Excerpt from American Police Systems This study, which I undertook at the invitation of the Bureau of Social Hygiene, as a companion volume to European Pol/ice Systmns, was practically completed when the United States entered the war in 1917. Thereafter for over two years and a half my time was so occupied that there was no opportunity to get the manuscript ready for the press. Only recently have I had leisure to finish it, and its publication now is due largely to my associate, Mr. Leonard V. Harrison, whose research and investiga tion in the last six months have brought my material up to date. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
