dressing room is given in Plate II. This increases the size of the .ruck to 6 by 14 feet. These dressing rooms afford complete privacy 'y means of sliding doors and substantial shades. Comfortable stools for mothers with babies are provided. There is an entrance at one end of the truck and an exit at the other, thus avoiding the confusion and congestion that would result if visitors were obliged to retrace their steps.

During the day the truck is well lighted by means of four windows, 2 feet square, on each side of the car. These are placed sufficiently high to be beyond the reach of prying eyes and are further protected, as are the glass inclosures of the front and rear dressing rooms, by heavy shades matching in color the outside of the truck.

For night work the truck is equally well lighted by two electric systems, one for a current of 6 volts supplied by the truck's own batteries, and the other for 110 volts furnished from a convenient local building. Two heaters supplied from the latter source keep the Special comfortable in moderate weather. In very cold weather, a kerosene heater adds to the comfort of the rear dressing room during the early morning hours.

There is an excellent water supply, provided by a 15-gallon tank placed above the chauffeur's seat and piped to a stationary washstand in a front corner of the car. The washstand is equipped with a faucet and drainpipe. The space above the chauffeur's seat is further utilized for the storage of exhibit material, consisting of a projection machine, films, stereopticon slides, and miniature models showing good ways to bathe, clothe, and feed young children. There is also a large roll of panels, charts, and posters illustrating various phases of child welfare.

Above the wheel housing on one side are cabinets and closets for the storing of an astonishing supply of bulletins and leaflets for distribution. These consist of the publications of the Children's Bureau and other Government departments, and also of those of the State board of health of the State visited. There are also filing cases for records, reports, and the like. Occupying similar space on the opposite side of the truck is a table for the examination of children, the space under the table being filled with large drawers for smocks, sheets, and small blankets for the protection of children during examination; and smaller drawers for stethescope, tongue depressors, and a stock of celluloid toys for the diversion of timid children. At one end of the conference room are a measuring apparatus and standard scales, adjusted to ounces and provided with an automati

Personnel.

The staff required to do this type of work to the best advantage must consist of

First. A woman physician, preferably a pediatrician with a keen appreciation of social service and public-health methods. She must have also a practical working knowledge of rural people and conditions, understanding their resources and their limitations.

Second. A public-health nurse, especially trained in the care of children, and with the social sense well developed. She must have also a working knowledge of dietetics and keep herself informed as to the foods available in the small rural home.

Third. An advance agent, a person capable of representing her department creditably. She must be able to address prominent citizens or groups, must be a good organizer; at the same time, when her advance work is over, she must be a valuable addition to the staff of the Special, demonstrating the exhibit, supervising the efforts of the committee to keep things running smoothly in the waiting room, and assisting in the clerical work necessary at the end of the day, editing the more or less elaborate medical records kept for statistical purposes. About two weeks before the close of the study in one county, it is necessary for the advance agent to pave the way in the next district, thereby avoiding expensive delays of the Special and its staff.

Fourth. An expert chauffeur, capable of repairing the truck and keeping it in perfect condition; of running the projection machine and of making himself generally useful. Under his guidance, the staff must hold itself in readiness at any time to lend a hand in bridge building, road construction, electrical engineering, and the like.

It is suggested that the staff of such a project be selected with a view to their special fitness for this kind of work; that they be practical, adaptable, with a thorough understanding of rural people and conditions and with an ever-present sense of humor to tide them over the rough places. Above all, they must have an abiding faith in the worth of their work and be prepared to offer results accomplished as a measure of their ability.

Method.

The method adopted by the Child-Welfare Special is to accept the invitation of a State board of health which is interested in cooperating with the Children's Bureau in working out a method of securing better conditions for its children. The fact that there are now divisions of child hygiene in 32 State boards of health, as compared with 6 before January 1, 1917, is significant of a belated but wide
