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.

A little moderate exercise every day is the ideal, especially if the exercise is in the outdoors.

Are Skyscrapers Bombproof?
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.
