EDITORIAL ANNOUNCEMENT

This volume is one of a series of Monograph Supplements to the
Journal of Criminal Law and Criminology. The publication of the
Monographs is authorized by the American Institute of Criminal
Law and Criminology. Such a series has become necessary in
America by reason of the rapid development of criminological
research in this country since the organization of the Institute.
Criminology draws upon many independent branches of science, such
as Psychology, Anthropology, Neurology, Medicine, Education,
Sociology, and Law. These sciences contribute to our
understanding of the nature of the delinquent and to our
knowledge of those conditions in home, occupation, school,
prison, etc., which are best adapted to elicit the behavior that
the race has learned to approve and cherish.

This series of Monographs, therefore, will include researches in
each of these departments of knowledge insofar as they meet our
special interest.

It is confidently anticipated that the series will stimulate the
study of the problems of delinquency, the State control of which
commands as great expenditure of human toil and treasure as does
the control of constructive public education.
