ABSTRACT
Although, strictly speaking, according to definition and according to law, neither a concubine nor a mistress is a prostitute, in real life the line between the one and the other is so difficult to designate and so very often overlaps that in any study of prostitution some attention must be given to both these social types. And it may safely be asserted that just as in the past nearly every concubine was guilty of prostitution either incidentally or fortuitously, so to-day there are few “kept women” who do not ply the prostitute's profession in some form or other and under the protective covering which their lover's patronage provides.
