Some of the advantages claimed for the new method are that there are no intervals between successive pictures, but each succeeding picture dissolves into the one preceding it in exact proportion as the volume of light shifts from one to the other; that there is no flicker; and less danger of fire because the projecting light does not reach the film directly, but is reflected by the mirrors; and that the front seats in an assembly room would be made as desirable as any other seats. =BOSTON CONFERENCE ON ILLEGITIMACY= Perhaps in no field of social work are the factors less adjusted, the issues more baffling, than in that relating to unmarried mothers. It has become not only desirable, but positively imperative, to a wise pulling together for the workers in Boston dealing with problems related to illegitimacy to unite in some sort of permanent group for free discussion of aims and means. The Conference of Workers on Problems of Illegitimacy which was organized in Boston last year has had a fruitful year of discussion. Each month some general question has been up for consideration, the question always being precipitated by the detailed story of some puzzling specific case. In this way have been thrashed out the following questions: What shall we do with unmarried mothers who are unfitted for housework? Is it ever advisable to separate the child from a normal mother? Is institutional or private care best for a pregnant girl and under what circumstances is each preferable? What shall we do with pregnant girls from other states or countries? The conference was pretty fully agreed upon the policies of treatment that follow. It is advisable to keep mother and child together where possible if the mother is in any way capable of bringing up the child. In cases where the mother is unfitted for domestic service it may be decidedly wiser to place her where she is happier and more efficient, in a factory, for instance. But even here financial responsibility for the baby, and at least weekly visits to the child, should be insisted upon. It is desirable to send back to the states or countries from which they come girls who arrive here pregnant in order that each section may develop care for its own unmarried mothers. Although this may mean old-fashioned care in the individual case because of the lack of modern agencies and institutions in places from which the girls come, it is one of the means of making localities that are not equipped to deal with such situations more alert to their responsibility. It is difficult to determine in what cases individual care or institutional care is wise. Particularly wayward girls often need the discipline of an institution, while the more innocent type are not helped by association with those they are sure to be brought in contact with, even in institutions that take only first offenders.
