During the preparation of this appeal for a Perfect Social Quarantine which shall allow no child _to escape_ intelligent care, the early galley proofs of the work were sent to a large number of persons, representing many different points-of-view, who are engaged in educational, correctional, political and business affairs in this country and in England for criticism and suggestions. The responses have been generous and much of the argument, as it stands, is based upon this testimony. While the book is in press, however, further responses are flooding in, which show the interest of all persons in the thorough aim appealed for. Those who have diverse ideas relative to grown-up questions of competitive interest are of one mind relative to giving babies a chance to develop the best there is in them. It is recognized that, under present conditions of neglect, there _are_ children born who "have no show on earth" to be good and useful citizens. It is also recognized that while one such example of neglect remains or is possible a nation has no good title or claim to the distinction of being called a civilized country. She can only be classed as "partly civilized," while there is one known case of neglect. Of especial importance are the suggestions and data collected and sent to the author from London by Julian Ralph, Esq., and promise of "a substitution of a heavy backing of easily obtainable facts for the appeals, which would render them unnecessary," from Prof. Graham Taylor, of the University of Chicago, and of the Chicago Commons Social Settlement. These must form a separate book, for they are too extended for the present volume, although their evidence adds valuable support. The history of child-training and child-saving in the United States is that of a discovery and wonderful development of latent forces, whose cultivation or neglect produces more happiness or more unhappiness, as the case may be, than any other source of power. Child-saving, in this country on an extensive scale, was inaugurated by Mr. Charles L. Brace, of New York, followed soon after by the Catholic Protectory under the care of the Paulist Brotherhood, and child-training was introduced from Germany into the United States by Elizabeth Peabody, of Boston. About the same time Dr. Thomas J. Barnardo, of London, established the "Dr. Barnardo Homes," whose chronicles during thirty-two years show only 1.84 per cent. of failure to make good children of the worst product of city slums.[9]
