A conference of constructive criticism of social service work will be held in Phillips Brooks House Wednesday evening at 8 o'clock. The conference will be attended by the professional workers of most of the settlements of greater Boston, by the professors that are especially interested in social work, and by students, especially those who have been engaged in settlement work this year. The conference will take the form of an informal discussion of the settlement work of the past year, and aims primarily to develop the points wherein the work can be made more effective for both the settlements and the students. L. Saltonstall '14, chairman of the social service committee, will preside. The discussion will be limited to one hour, after which there will be refreshments, and an opportunity will be given for the members of the University to meet the professional workers and talk over personally any points that have been brought out in the conference. Students who have not taken up social service work before are especially invited.
