 Practicing on a large scale, Grimm determined American troops rehearsed for the invasion of the European continent. Invasion barges towing low-flying barrage balloons, moving to secure a beachhead beneath the whine of live ammunition, pulling ashore in the wake of the infantry. Everything timed and planned to the minute as they prepare for the actual test. The amphibious training center and actual villages used to train men in the art of fighting from street to street. Everything is being overlooked. When the Americans move in, they're going to be ready for anything. In Washington, Lord Halifax and Britain's Foreign Secretary Anthony Eden call on United States Secretary of State Cordell Hull. Post-war problems of the United Nations and closer collaboration with Russia are topics of discussion. Mr. Eden's long friendship with the Soviet strongly qualifies him for this important mission. The newest thing in life-saving equipment, a 3,000-pound steel raft that floats on either side. Enough concentrated rations are carried to sustain 22 men for 21 days. A mirror with which to signal for help is part of its equipment. Kept afloat by air-filled bulkheads, the raft is dropped for a test. It's unsinkable and can't be swamped. Russian seamen in exposure suits abandon ship and prepare to man their life raft. A hoist sail, rig a shelter, and toss out a smoke signal that goes off when it hits the water. A real lifesaver for victims of shipwreck. The largest cities shiver in the grip of a howling blizzard, but war workers plow through snowdrifts and even help shovel the roads to get to their jobs. Train crews delayed as much as 24 hours cleared the tracks until service was resumed. Giant plows sweeping away the heaviest snow Canada has seen in 40 years. Workers stream back to their jobs as conditions return to normal. Shipment of those famous Missouri mules arrives at an army remount station in the American far west. And troopers have quite a time coaxing them into service. Fresh from the farm has a mind of its own. Soldiers soon find out to imagine this fellow under army discipline. But give him time as they're answering the challenge of war, filling the Navy's orders for ships and more ships. Yes, and shattering all records in doing the job. Workmen rush to completion new destroyer escort craft. Fast, trim 300 foot warships of prefabricated steel. Four months in building from keel to launching. First ready is the hopping. And the widow of her namesake swings the champagne. Type C fighter in the United Nations war against the submarine. At another yard, they're launching the latest tanker of America's great merchant fleet. She's one of the biggest oil carriers for Allied armies fighting overseas. It states Coast Guardsmen on horseback patrolling the wide and sparsely settled beaches of America's vast shoreline. On guard against spies and saboteurs seeking to land from enemy submarines. In portable radio, the mounted patrol covers the coastline from Maine to Florida, from Mexico to Canada. American lend lease tanks in Australia. Part of a full armored division takes the field. An impressive answer to any threat of Japanese invasion. Pleared to take up positions at strategic points along the Australian mainland, the division is prepared constantly for any attack amid exploding shells as General MacArthur puts his command through a real battle test. Battleships prove they're as tough as they come. In western Mexico, a new volcano comes to life. Huge columns of smoke below skyward as ripping explosions within the fiery crater are heard for more than 100 miles. From the subterranean inferno buried a village of 600 people. The cone after three days of activity is 1200 feet high, presents an awe inspiring spectacle. Explosions 30 times a minute. Amazing scenes of a phenomenon of nature.
