NURSERY HEATING AND VENTILATION
The subject of ventilation has been so fully discussed by the authors in another work that we refer the reader to The Science of Living, or the Art of Keeping Well.
For the first two or three weeks the nursery temperature should be maintained at seventy degrees Fahrenheit by day and from sixty degrees to sixty-five degrees by night. In the third week the day temperature should be sixty-eight degrees Fahrenheit measured by a thermometer hanging three feet from the floor. After three months the night temperature may go as low as fifty-five degrees Fahrenheit, and after the first year it may go as low as forty-five degrees.
The heating of the nursery is usually controlled by the general heating plant, and no matter what system of heating is maintained, humidifiers must be used, the necessity for which is doubled when the system is that of the hot-air furnace.
These shallow pans of water with large wick evaporating surfaces will evaporate from three to four quarts during the twenty-four hours. The humidity should be fifty throughout the seasons of artificial heating.
Many colds may be entirely avoided by the use of humidifiers or evaporators. The open grate is one of the very best means of nursery heating. Gas and oil heaters should not be depended upon for nursery heat. Only in an emergency should they be used at all, and the electric heater is by far the best device for such occasions.
