The United States imports annually almost $4,000,000 worth of canned crab meat, much of it king crab caught near Alaska.
Magic lanterns have joined the Army. Projectors that are direct descendants of the parlor lanterns of a generation ago are now being used to train rookies in the mechanics of modern motor vehicles. They are used with what are known as "educational reading slidefilms," because this has been found to be the speediest and most effective means of training mechanics. And speed is necessary, because by this coming June the Army expects to have 190,000 motor vehicles.

Spy-operated radio transmitters don't stand much chance of remaining undetected under the new set-up of the Federal Communications Commission. Direction-finding units in automobiles, fixed listening posts at 200-mile intervals, and ten long-range direction-finding stations now keep a 24-hour watch over ether activities in the United States and its territories.
American Type of Building May Be Answer to Raiders AMERICAN skyscrapers, often the butt of foreigners' jokes, stand ready to attain a new and indispensable usefulness. In the view of experts, they constitute a highly satisfactory, if not impregnable, defense against all types of bomb attacks. Even without added safeguards, they can safely protect millions of city dwellers and workers from explosives, gas, and incendiaries. And by the addition of sandbags and steel in vital sectors, they can be made almost as safe as the most elaborate shelter.
