As to scourers, the nature of the floors decided upon will determine what are wanted. Also, none of the midwives can be expected to be housemaids, even in their own rooms. They have too much to do. The pupil midwives would be expected to clean their own bed rooms, but not to scour, either for the patients or for themselves. There must be a common room for pupil midwives. Here they take their meals in detachments. Head midwife, as a rule, with first detachment; matron carving. Here they receive lectures and instruction from the physician accoucheur. The matron must have two rooms. The head midwife may have two rooms. She will expect to have her tea in her own room. The head midwife, her assistants, and all her staff, should be lodged in a central position, and there should be ready means of communication with these quarters, both by bells and speaking tubes, from each pavilion and delivery ward. A regular night service in a lying-in institution being impossible, the head midwife, when she goes her last round at night, say between eleven and twelve P.M., stations other watchers for any emergency arising besides those now to be mentioned, who are for the night nursing of ordinary cases. For this one pupil would probably be told off for each four wards or beds, and one extra for the whole floor, who must not be an inexperienced pupil. Her duty would be to visit each pavilion on her floor, and to have all in readiness in the delivery ward for cases coming in at night—a not infrequent occurrence. The head midwife would also arrange for the special care of any critical case at once, on the patient being conveyed to her own ward, or to that adjacent to the delivery ward. In so large and therefore busy a lying-in institution, it would not be desirable to call up all the pupil midwives to every case coming in the night. They would be appointed day by day alternately, and the number told off for the purpose would be called to any case coming _that_ night. It is therefore most desirable that the sleeping-rooms or compartments (each with its own window) of the pupil midwives should be arranged in at least three reliefs, so that the occupants of one dormitory, or relief, could be called by a bell from the delivery ward ringing into that dormitory without needlessly disturbing others. In so large an institution the head midwife even cannot attend every night case. The assistant must be a well qualified midwife, who can take her turn in attending night cases, calling the head midwife if necessary. Through all this organization, however, as far as possible, each pupil is told off to be in charge of a mother and infant from beginning to end. And there will always be unfortunately a certain number of cases, each requiring a nurse constantly by her side day and night. It is obvious that the same woman cannot do this for a succession of days and nights.
