The handholds on stone jars are usually not large enough to carry the jars safely when they are full. If the handles of an old galvanized tub are riveted to a leather strap long enough to reach under the bottom and almost to the top on each side, the jar can be handled without danger of being dropped. The fingers are placed In the handles to carry the weight, while the thumbs are used to keep the jar from tipping. By placing a buckle near one end, the strap may be used for carrying a jar of any size. - Contributed by C. H. Floyd, Elwood, Ind.
