Meantime John L. Lewis personally called off his 40,000 coal miners, Colonel Janeway disarmed Mayor Shields's vigilantes and Johnstown settled down to its first taste of martial law since the 1889 flood. C.I.O. picket lines, now unnecessary, were withdrawn. Despite Mayor Shields's cry of "usurpation," Colonel Janeway took over full police powers where they touched on the strike, sending the local police back to their beats or traffic posts. Otherwise the civil authority was not disturbed...
...Another weekly got a new publisher last week when Malcolm Muir resigned as president of McGraw-Hill (Business Week, Engineering News-Record, Coal Age, Aviation) to take over the guidance of News-Week...
...Carbonic Corp. handles most of it. Made in 36 plants in the U. S. and Canada, its gas is delivered to 10,000 U. S. beverage bottlers in 400,000 steel cylinders. There is a steadily widening use for liquid carbonic in asbestos composition shingles, cement products, fire extinguishers, coal blasting, air-cooling. At low temperatures under pressure, liquid carbonic forms what is known as dry ice. Selling dry ice since 1931, Liquid Carbonic now dominates the current annual U. S. production of 200,000,000 lb., most of which goes to ice-cream companies...

Looking toward the time when Earth's supply of coal & oil gives out, imaginative scientists have long tinkered with ponderous reflectors and batteries of photoelectric cells to harness the sun's outpouring of energy. Lately they have realized that plants are better converters of this energy than any man has ever devised. Ordinary cornstalks, ground to powder, can be used as a furnace fuel, like powdered coal. The Cabot researchers will try to develop bigger, more vigorous and faster-growing trees by artificial pollination and juggling of chromosomes (heredity elements in the germ cells). After 50 years...
