UNITED STATES PUBLIC HEALTH WATER TESTING CAR.
An instance of the work being done by the United States Public Health Service in relation to testing waters was seen just recently in Leavenworth, Kan., where as a step in solving a typhoid epidemic Dr. Akin, of the U. S. Public Health Service traveling car, took four samples of the water used in the city, the car being equipped with a laboratory, and it travels throughout the country. It had been sent to Leavenworth for the purpose of making tests of water and milk supplies and it was announced that it would remain in that city until a permanent laboratory can be esablished. This excellent work on behalf of purity of water supplies and public health is one by which much and far-reaching good can be accomplished, for not only is a test made to determine whether the supply is contaminated, but, as in the case of Leavenworth, the establishment of permanent means of testing the local supply is the logical result of the illustration of the importance of such work. The car itself is equipped in such a way as to recommend it for efficint service to those interested in work of a kindred character. The center of the car is used as a laboratory in which tests are made. The car is supplied with an incubator in which the samples of water are kept for twenty-four hours and then, if satisfactory results are not obtained, it is left for twenty-four hours more. Instruments and chemicals used to germinate various kinds of germs are at hand. The car is supplied with an ice box, in which vials of germs are kept, and this box holds eight hundred pounds of ice, which it put in from the top of the car. One end of the car contains the staterooms of the doctors, while the kitchen is located at the other end, so that this car, which travels throughout the country in the interests of good health, appears notably complete in itself.
