The lectures were given by Nellie M. Smith whose book containing these talks, The Three Gifts of Life[1] has recently been published, and many of those who attended the lectures purchased copies of this volume with the intention of giving them to their mothers or younger sisters to read.

These same lecturers are now being given by a large industrial corporation in this city which is always ready to investigate thoroughly, any work that makes for the betterment of the life of its workers. Furthermore, the question of giving these lectures to six other manufacturing establishments is now being seriously considered. It might be well to mention that these lectures were merely announced to the workers and in no case was attendance compulsory. They were given without charge during regular working hours. Our workers have surely benefited by the knowledge gained through this course and the writer trusts that many other manufacturing concerns will give this matter serious thought. It is an established fact that the worker cannot get full production from any power machine unless the human machinery is properly cared for, and but few persons thoroughly understand how to best care for themselves.

SEGREGATING VICE TO THE EDITOR: It is not a little curious that in all the agitation on the vice question no one has suggested what has always seemed to me the evident solution of the whole matter. Without a second thought, if there were no men there would be no prostitutes; the men are the sole and only source of the whole evil. I am aware that segregation has its drawbacks. It does stimulate clandestine prostitution. It has the fault of legalizing a shameful business. Also under our present conditions it supplies an opportunity for graft. But overruling all these disadvantages is the fact that it facilitates the catching of the men. This is impossible in hotels and apartment houses, but if men found frequenting the segregated district were seized and submitted to compulsory examination, it would only be the blatant sinners who would ever run the risk, and the number of such customers would be greatly reduced. This suggestion may appear Utopian, for do not the originators of prostitution themselves make the laws? However, there now seems some chance of the public conscience, male and female, being widely aroused and it is possible that the originators of the whole evil may not escape the dragnet. H.
