��Foiling the Pickpocket and Protect- ing Your Watch

AVERY simple device to prevent your watch from falling out of your pocket has been invented by Carl Anton Nord of New York City. It consists of a case stamped from sheet metal and lined with soft fabric. The case, which is fast ened securely to the pocket, has a notch at the top, which is rounded to admit the stem of the watch. The stem of the watch is pushed down inside of two prongs which project slightly above the case.

These prongs require some effort to separate them, so that the watch can not fall out or be easily pulled out by a pickpocket, without the owner being immediate- ly aware of it.

��The watch is held securely in which is fastened inside the pocket

��southern California when motoring off the main highways in the mountains or deserts, as it is sometimes necessary to do there as well as in other sections of the country.

To demonstrate the possibilities of an invention to be used when the car is mired, a Los Angeles automobile dealer carried out the test shown in the illus- tration below. The rear end of a car weighing 2,250 pounds and equip- ped with a 24-horse- power engine was lift- ed high above the floor by means of ropes at- tached to the floor beams above and passed around hub drums fixed to the rear wheels. In actual practice the ropes will be led forward to heavy stakes or other ob- jects strong enough to resist the pull.

���Testing a Car's Power to Pull Itself Out When Stuck

��Take Good Care of the Eggs This Year— You Will Need Them

THE United States Department of Agriculture has called attention to the fact that carelessness in handling eggs causes an annual loss of over thirteen millions of them. The loss is due to small cracks in the shells. Once an egg Shell is cracked even so slightly that the eye cannot detect it, the delicate, protective, gelatinous coating which Na- ture provides as a lining for it becomes exposed to the attack of germs and mold forms, lessening the keeping quality of the egg.

Five per cent of all cold storage eggs, the specialists find, spoil because of these small, scarcely perceptible cracks. Just a little more care in handling the eggs on the farm and in their transit to market and to the con- sumer will greatly lessen this

��important wastage.
