An iceless refrigerator may be made from a rectangular frame of wood, to which heavy canton flannel is buttoned or tacked. On the top of this should be placed a pan of water with strips of cloth extending from the water to the covering of the frame. This will conduct the water from the pan out onto the cloth. The number of strips of cloth regulate the rapidity with which the water is carried to the sides of the refrigerator. The food is set inside (Fig. 58.) The refrigerator should be placed in a shady spot where the breezes can strike it. Iceless refrigerators must be kept clean, and the covering of cloth should be washed occasionally. [Illustration: FIG. 59. Device for cooling food.] Some iceless refrigerators are enclosed in a chimney-like closet built on the house, the cold air coming in at the bottom and being drawn upward by the natural draft of the chimney-like structures. This draft hastens the evaporation of the water. Such refrigerators are expensive and less satisfactory than ice ones. =126. Small Cooler.= A few things may be kept cool, like a bottle of milk and a small dish of butter, by setting them in a shallow pan of water and covering them with a flannel cloth which comes down into the water and so remains moist (Fig. 59). The evaporation of the water from the flannel cools the food somewhat below the temperature of the surrounding air. =127. Covered Pail.= Another device is a metal pail (Fig. 60) covered with a heavy layer of cloth and a pan set on top of the cover. Into the pan is put some water and strips of cloth to conduct out the water. This may be hung in the kitchen window if it is shaded. The cover and the strips must be secured so that they will not blow off. [Illustration: FIG. 60. Covered pail for cooling food.] =128. Unglazed Earthenware.= Unglazed earthenware pitchers and jugs make excellent water coolers. The water is put in them, and, as the container is porous, a small amount filters thru the earthenware, and, as it reaches the surface and air, it evaporates, cooling the remaining water. =129. Cooling with Running Water.= A very little stream of water from a faucet will cool the baby's milk and keep it from souring. The bottle should be set in a pan of water which is constantly renewed by the small stream running from the faucet. (Fig. 61.) This method of cooling should be used only in homes supplied with water from a spring or in an emergency. Under most circumstances, it is too extravagant a method of keeping food to be recommended. In cities it should be prohibited because it might cause too great a drain on the city water supply. [Illustration: FIG. 61. Cooling with running water.]
