Raw milk plays so important a part in the spread of disease that its fitness for human consumption is open to serious question. Certified milk, where obtainable, is safe but expensive. Boiled milk is safe, but changed in taste and to some extent in quality. If milk is heated to 142°-145° F. and kept at that temperature for 30 minutes all disease germs in it are killed. This process, called pasteurization, renders milk safe. The objection is sometimes made that continued use of pasteurized milk for infants causes scurvy, but in New York City where over 90 per cent. of the milk is pasteurized no increase in scurvy has been noticed, while a large diminution in deaths of infants from diarrhœal diseases has resulted, as in all cities where pasteurization is required. The following is a simple method for pasteurizing a quart bottle of milk. If the directions are exactly followed the milk will be pasteurized at the end of the process; no thermometer need be used. To prevent the bottle from breaking, it is first warmed by placing it for a few minutes in a pail of warm water. "From the results of the experiments it was concluded that any housewife can pasteurize a one quart bottle of milk by: 1. Boiling 2½ quarts of water in a large agate saucepan; or better 2. Boiling 2 quarts of water in a 10 pound tin lard pail, placing the slightly warmed bottle from the ice chest in it, covering with a cloth and setting in a warm place. At the end of one hour the bottle of milk should be removed and chilled promptly. The water must be boiled in the container in which the pasteurization is to be done."--(Ruth Vories, in "Health News," Sept., 1916.)
