is essential to a valid union, the optional civil or religions ceremony, at the pleasure of the persons contracting, is sanctioned by the law. As already seen, this dual system has its roots planted deeply in the history of two centuries. It is clearly entitled to be regarded as the American plan; although since 1836, with important modifications, it has also been accepted in the British Isles. It does not follow, however, that it is the ideal plan. It is too complex; and it is an obstacle in the way of developing the most efficient system of matrimonial administration. It is inconsistent with a proper social control. It will prevent the attainment of the "maximum of simplicity and the maximum of certainty" in matrimonial legislation. It is awkward, thoroughly illogical, to intrust the execution of that part of the law on which publicity and security so much depend to two different classes of persons: the one consisting of civil officers created and wholly under control of the state; the other in its origin, its personnel, and its character completely beyond such control, and only subject to administrative rules and restraints. With this system it will be very difficult to establish a proper standard of special fitness, of special knowledge, such as is highly needful to exact from public servants intrusted with functions of vast social importance. European peoples have reached a wiser solution of the problem in prescribing in all cases without exception, as the prerequisite of a valid marriage, the obligatory celebration before an authorized civil officer, leaving the wedded pair to decide, as wholly a private matter, whether a religious ceremony shall be added.
