The objective of this book is to better the care of boys and girls both here and elsewhere. The manuscript of this book was completed in 1922--a fact which needs to be kept in mind in reading it. Few changes have been made in it since then. The three years and more since its completion have been required to arrange for its publication and to put the manuscript through the press. It is sent out now with a keen appreciation of its shortcomings, statistical and otherwise, but with the hope that it may add something to our accurate knowledge of the conditions which surround youth. This book looks at the investigation and methods of children in school and at work between the ages of fourteen and eighteen years.
