ACKNOWLEDGMENT.

To the employing public, who have come to realize that the work of the Bureau is aimed at the improvement of the social and economic conditions of the bulk of our population, and who have shown a willingness to assist rather than resist the officers of the Bureau: To the District Attorneys, Police Departments, Probation Officers, Attendance Officers, and other officials who have rendered valuable assistance in the enforcement of labor laws: To the Judges of the higher and lower courts, who have upheld and made effective those laws designed for the protection and uplift of the women, children and men who must labor: To the official staff of the Bureau, whose loyalty and careful work are largely responsible for the results achieved: To each and all of them I tender my thanks.

JOHN P. McLAUGHLIN,

Commissioner.
