And now the educated hog. The office of exhibits, Department of Agriculture has prefected the "educated hog." It talks, n'everything. The talking is done by means of concealed phonograph records and the action is accomplished by means of compressed air. The hog tells those interested all about the damage done to members of his family by the roundworm and as the roundworm gets to work the hogs are deflated by the letting of compressed air. This model, 4 feet 6 inches high will be exhibited the first week in December at the live stock show in Chicago
