One great mistake made by those who consider social problems is that they either regard man apart from his surroundings or as one of a mass, instead of as a member of a family or group. Family life is the common form of social life, and whatever its defects, it is the form that is likely to persist without very great modification. The family is based on marriage, and the parties married are not one in blood, though the children of the marriage are. The family tie, therefore, is not solely a blood tie. The members are brought up in a sense of mutual obligation and in the knowledge of their interdependence. Occasionally adoption is a means of entering a family. When a person is adopted early in life, it is difficult to perceive any difference in the tie that binds him and the other members of the family. There is another and a temporary adoption which is much more frequent than is generally imagined, and the existence of which prevents a great many lads and more girls from becoming destitute and from drifting into evil courses. In Glasgow there are many young persons who, having no relatives of their own with whom they can live, or the relatives being unwilling to take them in, obtain lodgings and help from others. In the case of the girls, they pay a portion of their earnings to the common treasury and give their services in aid of the work of the household, being treated in all essential respects as members of the family. Many of them are not earning a wage sufficient to enable them to pay for lodgings at the ordinary rate; and it is this arrangement that explains why so many who are in receipt of small wages are able to live respectably, and do so. Attempts have been made to provide hostels for such wage-earners, on this very ground that their income is insufficient to enable them to hire a room with attendance; and the hostels are frankly admitted to require charitable aid for their upkeep, though they are in their management institutional; that is to say, they aim at economy by the subdivision of labour. It never seems to have occurred to those who appeal for funds to establish such places that the girls in the majority of cases have solved the problem for themselves, by what I have called, and what practically is, a kind of adoption; and that their solution is the correct one--that the minority who have failed to obtain adoption can be better helped by securing it for them, if necessary by subsidy, than by bringing them together in an institution.
