CANADIAN NAVY MAINTAINS VIGIL Canada's Navy keeps the seas: through fair weather or foul, in rain or fog, ships of the Koyal Canadian Navy maintain their vigil at sea. Here one is seen, looming out of the mist, while in one of her consorts a seaman stands his watch. Canada is celebrating "Navy Week." Throughout the Dominion, from the Atlantie to the Pacific, In industrial centres and prairie village*, the Navy League of Canada is calling the nation to pay tribute to the men of the sea who are winning the war of the Free Peoples. Navy Week, sponsored by the Navy League of Canada, in this second year of war means more than ever before to a Canada which has seen her N avy grow, since war was declared, from less than 2,000 officers and men to more than '26,000 officers and men each of whom is helping in Canada's larire part in the war at sea. What Science Is Doing WHAT SCIENCE IS DOING? .. SQUEAKING DIAMONDS Touch a diamond and almost any pearl with a piece of dry Ice and they squeak. Imitations don't. So reports Miss Mary D. Waller, of the London School of Medicine for Women. The explanation is simple. When dry ice (tolid carbon diox- ide) is heated it turns at once into a gas and skipe the liquid stage. Touch a metal plate with a point of dry ice, and heat passes from the plate to the dry ice, whereupon gas is formed. The stream pushes away part of the plate in front of it, whereupon it stops and the plate springs back. This happens about 1,000 to *,- 000 times a second, so that we have high-pitched sound vibra- tions. Touch a piece of glaas or some other non-conductor la this way and no squeaks are heard. Miss Waller has learned the trick of producing continuous, very high musical notes from dia- monds snd pearls. A very light, steady touch is demandea to make a gem sing, and so is a sense of when the vibrations are about te begin. OCEAN YIELDS MAGNESIUM Recovery of metallic magnes- ium from seawater at Freeport, Tex., by the Dow Chemical Com- pany of Midland, Mich., recently was called the outstanding chemi- cal engineering achievement since 1940. At the Freeport Plant, some 300,000,000 gallons of raw ocean water are daily processed to pro- duce 100,000 pounds of metal as well as large quantities of bromine for anti-knock motor fuels. Magnesium alloys (known as Dowmetal), are the lightest structural metals used in industry, being one third lighter than alum- inum with comparable strength and toughness. Today 100 per cent of Dow's output goes into defence used, particularly in cast- ings for airplanes, each of which on the average will contain 1,- 000 pounds of this remarkable metal.

"Did you hear about Jones am his car?" said Brown to his neigh- bor over the back fence. "No, what about it?" "Well you know, it's a very old car, and odd bits are always falling off when he KOBS for a ride. So he got the idea of tying magnet behind to pick up the parts which dropped." "Smart idea, anyway." "Yes, but in the end Jones found himself riding on the mag- net!" "Yet," id tha great man, "I woke up one morning; and found myself famoui." "It was slightly different with me," sighed the other. "I found myself famous and then I woke up." General: "Confound it sir; why can't you be more careful?" Selectee: "What have I done, Ir?" General: "Instead of address- Ing this letter to the Intelligence Officer, you have addressed it to the Intelligent Officer, you should know that there is no such person in the army." 'And what is synonym, Willie?" asked the teacher. "A synonym," said Willie, "is a word that you use when you can't spell the other one."
