It looks like Helium will remain cheap, at least for a few more years. (BTW, every single publication I saw felt the need to make a Helium pun in the headline) Helium Once Worth $5,000 Costs under Two Cents Twenty years ago it would have cost you $5,000 to buy enough helium gas to inflate [...]

By Charles Morrow Wilson THEY were having a light dinner party. Samuel G. Hibben, illumination engineer and authority on light and responses to light, was host. Food, drink, and chef were the best that money could buy. There were musicians, gay storytellers and all the trimmings. The host had even arranged special lighting for the evening. Instead of ordinary clear or frosted lamp bulbs, he substituted especially designed filter lamps which cut out all the ordinary spectrum . of colors except greens and reds. Guests strolled in to the table, hale, hearty and merry. Then they began to notice that their eyes were deceiving them. Delicious steaks were whitish gray. Celery was gaudy pink. Milk appeared blood red. Salads were bright blue. Lemons became oranges. Coffee changed to pale yellow. Fresh green peas appeared black. Peanuts seemed bright red.

THE hush of early morning is broken only by the staccato beat of an isolated gasoline engine in a tent in an alfalfa field just beyond the city limits. A sleepy radio operator reads the meters of a portable transmitter arid makes an entry in his log. "One more hour," he yawns, "and the job is finished." On the other side of town a mysterious looking car pulls up at a corner. The driver reads the street names, marks the spot on a map, then snaps on a complicated looking receiving set hung from the roof behind his seat. No sound comes forth. Instead, the needles of two meters swing across the scales. Rotating the loop aerial protruding through the roof, the driver secures maximum reading, makes a note of it, then goes on down the street.

By H. W. MAGEE PART I THE canvas-topped prairie schooner, the original home on wheels, crawled across a continent and transformed it into a nation. This slow, clumsy conveyance carried the pioneers and their meager belongings across the plains and pushed our frontiers westward to the Pacific. Today America is returning to the covered-wagon era, and the modern covered wagon again is extending our individual boundaries by releasing us from permanent abodes and providing a mode of travel so comfortable and inexpensive that we are likely some day to become a nation of nomads. Today's prairie schooner is a streamlined, luxury-crammed "cottage'' on rubber-tired wheels. It is hitched to a 100-horsepower car instead of to a team of oxen. Thousands of families are towing these rolling homes behind their cars today, living in them as they travel. They stop where fancy dictates, and wherever they stop, home is waiting just behind the rear bumper. When they tire of sitting still, they moveâ€”and take their home along.
