PREFACE The present volume is substantially an English version of Dk Aybeiter- Verchemtg ia den Vereinigten Sfaatert volz North-America.Considerable new material has been added but the movement is now so rapid that before proofs can be read new and important events may occur. In preparing this volume the statistics used have been compared, as far as possible, with the primary sources. It is difficult to avoid errors, and the author will be grateful for corrections. The summary of European laws is added in order to indicate the various tendencies of thought and activity in this field. Imitation of foreign measures is impossible, but each scheme may suggest a new starting-point for American legislation. In the Appendix will be found the regulations of several important schemes of insurance which have been drawn up by actuaries, with the best legal and business advice. Some of these plans have already endured severe tests in practice. l Published by A. Troschd, Berlin, 1907, as Heft XVII of Dr. Zachers Die Arbeiter-Versichermng din Auslands. The publisher and editor of that series graciously gave permission to publish an English edition...
