If, as Abraham Flexner says, “it is the unskilled daughters of unskilled men” that become the prey of traffickers in human souls and bodies, someone pays the money, and as a rule it is not the poor who have that money. The well-to-do pay, not only with silver and gold, but with pain and suffering, and with syphilitic and degenerate offspring. The revelations made by men to mankind and by some women to all women show how large a part sex plays in crime and vice of all kinds; and women know well that sex cannot be understood by men alone or protected by men alone. At least it is certain that one sex has failed as the arbiter of the destinies of the other, and better results already are in evidence from the combined occupancy of the field of public corrections by men and women. The full import of women’s advance into the field of criminal law and administration is not yet widely appreciated, even by women themselves, so gradual and unobtrusive has it been, for the most part. Women began quietly as minor assistants to the courts of law, it being thought that the mysteries of that great science were too deep for the feminine mind. As the law schools and the secrets of the guild were opened to women, they began to bring into the administration of the law here and there the spirit of social service. As they acquired the technical equipment, which was soon discovered to be not half as formidable as the gentlemen of the powdered wig and lordly mien long represented, women began to assume even judicial functions. PROBATION Protective and probationary work naturally fell to women’s share very early in the growth of their interest in law enforcement. Even to the most obtuse masculine mind, it became apparent that women were fitted to look after women and children held temporarily under the tutelage of the courts.[46] Even this, however, was a great gain for women. Probation officers were called into daily consultation with judges, members of the district attorney’s office, the chief of police and his subordinates, and the opinions, reports and investigations of women officers were soon shown to be of the highest value to the judges, attorneys and police. Hundreds of women thus won by sheer efficiency the respect of those in charge of law enforcement.
