Excerpt from Outline of Practical Sociology: With Special Reference to American Conditions In preparing this work, I have made frequent and generous use of the results of official investigations which have been carried out under my own direction. They comprehend the work of more than twenty-five years; and as they cover many features of the present volume, I have felt justified in using them more freely than other official publications. The reports of the various State bureaus of statistics of labour offer a vast amount of valuable but cumulative material along the very lines of my own investigations. I have also drawn freely from lectures on social economics delivered at the Catholic University of America and at other institutions, and free use has also been made of articles that I have published in various magazines. The editors and publishers of The Forum, North American Review, Popular Science Monthly, Atlantic Monthly, The Chantanquan, Munsey's, The Bulletin of the Catholic University of America, Annals of the American Academy, and The Journal of Sociology of the University of Chicago, have generously given their consent for the use of articles or portions of articles that have appeared in those periodicals.
