��A back-yard swing and two hobby-horses made a new plaything for children

��The Hobby-Horse Turned Into a Swing

A CHILD'S lawn swing with a hob- by-horse for the chair, is the in- vention of a Missouri man (James A\ . Moore, of St. Joseph, Missouri). The hobby-horse is pivoted on a platform. It is connected with hangers, by which the platform ' is supported from the framework. The hobby-horse is rocked automatically by the oscillation of the swing, giving its juvenile riders a very agreeable thrill.

��A Shell That Melted Money in a Ship's Safe.

NE of the most telling samples of the terrific effect of naval gun fire is a piece of metal recently taken from the hulk of the famous German commerce destroyer Emdcn. This souvenir con- sists of a lump of metal which was smooth on one side, but on the other side resembling a piece of jagged rock. The metal consisted of a portion of the fireproof safe of the Emden and some silver coins from a drawer in the safe. The explosion of a shell probably blew some of the dollars into the

steel, the heat fusing the whole into a

mass of iron and silver.

��Lifting a Wagon to Dump Its Load

A NOVEL method of solving an un- usual difficulty met by a contractor at Hamilton, Ohio, is shown in the ac- companying illustration. Upon com- mencing his work he discovered that the gravel storage-hopper above the con- crete-mixer was in an inaccessible loca- tion for the traffic. Owing to the street traffic there was no room for a gravel pile. It became necessary to resort to drastic measures.

When a gravel-wagon comes to the spot to discharge its load, the horses are imhitched and the wagon tongue is re- moved. Then a pair of hooks is at- tached to the front axle, and a pair of rings slipped over the hubs of the rear wheels. By means of a crane the wagon is lifted bodily over the hopper. Upon arriving at the desired location the driver pulls the dump lever and the load of gravel drops into the hopper.

���The wagon is raised bodily and its load

dumped in the chute. The scheme saves

shoveling or a conveyor system
