EDITORIAL ANNOUNCEMENT

This volume is one of a series of Monograph Supplements to theJournal of Criminal Law and Criminology. The publication of theMonographs is authorized by the American Institute of CriminalLaw and Criminology. Such a series has become necessary inAmerica by reason of the rapid development of criminologicalresearch in this country since the organization of the Institute.Criminology draws upon many independent branches of science, suchas Psychology, Anthropology, Neurology, Medicine, Education,Sociology, and Law. These sciences contribute to ourunderstanding of the nature of the delinquent and to ourknowledge of those conditions in home, occupation, school,prison, etc., which are best adapted to elicit the behavior thatthe race has learned to approve and cherish.

This series of Monographs, therefore, will include researches ineach of these departments of knowledge insofar as they meet ourspecial interest.

It is confidently anticipated that the series will stimulate thestudy of the problems of delinquency, the State control of whichcommands as great expenditure of human toil and treasure as doesthe control of constructive public education.
