"The results of all the trustworthy observations and 

 experiments have been taken into account . . . 

 This book should command the attention not only of 

 students of sociology, but, as well, of philanthropists, 

 social workers, settlement wardens, doctors, clergy- 

 men, educators, editors, publicists, Y. M. C. A. sec- 

 retaries and industrial engineers. It ought to lie at 

 the elbow of law-makers, statesmen, poor relief offi- 

 cials, immigration inspectors, judges of juvenile courts, 

 probation officers, members of state boards of con- 

 trol and heads of charitable and correctional insti- 

 tutions. Finally, the thoughtful ought to find in it 

 guidance in their problem of mating. It will inspire 

 the superior to rise above certain worldly ideals of life 

 and to aim at the family success rather than an 

 individual success.— From the introduction by Edward 

 Alsworth Ross, Professor of Sociology in the Univer- 

 sity of Wisconsin.
