That to be used for infants should be strained through a thick layer of absorbent cotton or several thicknesses of cheese-cloth into quart glass jars or milk bottles which should be covered and cooled immediately best by placing the bottles quite up to their necks in ice water or cold spring water, where they should stand for at least half an hour. That required for children who take plain milk may now be poured into half-pint bottles, stopped with cotton, and put in the ice-chest, or the coolest place possible. This first rapid cooling is very important and adds much to the keeping qualities of the milk. Milk loses its heat very quickly when cooled in water, but very slowly when it is simply placed in a cold room. After standing four or five hours the top-milk may be removed; after twelve to sixteen hours the cream may be removed.
How should milk be handled when bottled milk is purchased?
It should be cooled as just described, as its temperature is usually somewhat raised during transportation If it has been bottled at a dairy, the cream or the top-milk may be removed after an hour or so.
How should milk and cream be handled when they are purchased in bulk?
Such milk should never be used for infants when it is possible to obtain bottled milk, as it is much more liable to contamination. Both cream and milk should be poured at once into covered vessels and kept in the coolest place possible. The cream and top-milk will seldom rise upon such milk with any satisfactory regularity.
What are the important things to be secured in nursery refrigerators?
Absolute cleanliness is essential; hence the inner portion should be of metal. Those made entirely of metal are unsatisfactory as in them the ice melts very quickly. If the ordinary metal refrigerator sold is encased in a wooden box, we have the best form. Another easy way of securing the same result Is to make for the refrigerator a covering or "cosey" of felt or heavy quilting, which can be easily removed when wet or soiled.
The compartments of the refrigerator should be so arranged that the bottles of milk are either in contact with the ice or very near it. The supply of ice should be abundant. Often the amount of ice is so small, and the bottles so far away, that the temperature of the milk is never below 60° or 65° F. To be really effective a refrigerator should have a temperature where the milk is placed of not over 50° F. The temperature should be tested with the nursery thermometer from time to time to ascertain what results are being obtained. Spoiled milk owing to a faulty refrigerator is to be blamed for many attacks of acute illness among infants. Next to the feeding-bottles it is the one thing in the nursery which should receive the closest attention.
