Cooling Foodstuffs with a Moist Rag and a Draft
It is not always necessary to keep milk and butter, or other foodstuffs, in refrigerator temperature to preserve hem, for 50 or 60° will often serve quite as well where the articles are to be consumed within a short time. To accomplish this slight degree of cooling, wrap a moist linen cloth, single thickness, snugly about the dish or package, and place it in a shallow pan of water, in an open window, out of the sun. The brick of butter should be placed on a support to hold it out of the water. The cooling is due to evaporation from the moist cloth. Not infrequently on a warm summer day, a thermometer with a bulb, wetted as suggested, will be 20° cooler in a breeze, than a dry-bulb thermometer.
