Silver Linings

> Because silver compounds (e.g., Argyrol) are potent germicides, a black silver-plastic mixture which can be permanently coated about the rims of drinking glasses and bottles was developed by Physicist Alexander Goetz and Bacteriologist Ralph L. Tracy of Caltech. Within a short while after lip contact, the rather decorative rim completely sterilizes itself.

> Because silver is the best electrical conductor and the rearming U.S. will be short some 770,000 tons of copper next year, the 100,000 tons of Treasury bullion might well be largely drawn into wire and installed in new defense plants this winter to save some 75,000 tons of copper. So suggested Robert E. McConnell at a convention of chemical engineers. Copper is priced at 12-c- a lb., silver around $10 a Ib. depending on when it was bought; but defense plants are well guarded and their wires full of deadly high voltages 24 hours a day. After the war the silver can be re claimed, restored to precious uselessness.
