The reorganization of a large institution for the care of mentally retarded children, Mont-Providence Hospital, is used as an illustration of the way in which such psychiatric ghettos can be employed in an active program of decentralization and regionalization in the field of child psychiatry. Furthermore, the many advantages of keeping both acute and chronic patients in some such institutions is emphazised in terms of teaching facilities, varying staff interest and stimulating research projects which would not be feasible without the concentration and the stability of population they offer.
