The Home and School League of Philadelphia has done valuable work in arousing interest in this direction, and now a number of such visitors are at work in the city supported by various private organizations. They are doing the same sort of work as that done by the visitors in New York and Boston, although from the reports it would seem that both in Philadelphia and Boston special attention is given by them to vocational guidance. A particularly valuable piece of work has been done by the home visitor appointed by the Armstrong Association to work among the colored pupils of Philadelphia; the Friend’s Preventive Association, the Juvenile Protective Association, and the Children’s Aid Societies, also support visitors. These are being used to an increasing degree by the Bureau of Compulsory Education of Philadelphia in carrying on the preventive work connected with that bureau. In Boston there are now five full-time and seven or eight part time school visitors. Each visitor is engaged by some private organization, such as the Women’s Educational Association, the Home and School Association, a group of settlements, or by some individual. She is attached to a special school or district and does all her work there. This is the arrangement in all three cities. The work has been supervised by a committee of the Women’s Educational Association, and this committee represents settlements and other social agencies. Work of this sort, but on a smaller scale, is being done both in Worcester, Mass., and in Rochester, N. Y., the visiting teachers working under the Public Education Association of New York have been increasingly effective in their efforts to solve for the often overburdened teacher problems connected with individual children. Efforts have been made from time to time by the supervising force to instruct teachers to visit the homes of the children in their classrooms and ascertain the conditions under which they were living, but with the present large size of classes in most public schools this has been found to be quite impracticable. Besides this, to overcome the difficulties in the way of a child’s education much visiting of an expert sort and many efforts for outside co-operation are often necessary, for which the teachers could not possibly find time. Separate visitors are therefore needed. There are so many illustrations of the sort of work they do, that it is hard to select one that is more telling than the rest.
