MOVING TROOPS across the oceans by the millions is one of the biggest jobs of global war. How is it done? Alden P. Armagnac will tell you about the ships that carry our armies abroad in the greatest mass movements of human beings ever made. You’ll be amazed at the complicated transport system that puts America’s fighting manpower on the fronts where it is needed.

EGGS KEEP LONGER and look better when treated by a process called thermostabilization, devised at the University of Missouri. The eggs are immersed in liquids, with air circulating around them, and warmed to a relatively low temperature so that heat can penetrate the eggs before any part is coagulated.

TRUE examples of practical American art are the familiar well-shaped game-bird decoys, such as those made to represent the duck, gull, sandpiper, goose, or curlew. An old decoy can easily be adapted for use as a mantel decoration, cigarette box, or lamp, as shown at the left.
