Winter's first major assault, a vast cold air mass from the Arctic, swept across the nation this week. Florida felt the chill fringes of it. In Grand Forks, N. Dak., the temperature dropped to 17° below zero. Around the stark deserted tipples of the coal mines from West Virginia to southern Illinois, a northwest wind whooped. John L. Lewis had a new ally...
Picketing in near-zero temperatures, the teachers were warmed by parkas, winter coats, ski pants and the comforting thought that most St. Paul citizens sympathized with them. Governor Edward Thye had said that teachers' salaries were too low. Parents living near the schools invited pickets in for a cup of coffee to take the chill away.

Magic Pellets. Schaefer's cloud-poisoning act was the fruit of long, careful experiment. After much research, he learned how to turn the trick in miniature.

He made a magic pass with a single pellet of dry ice. The fog cleared, and glittering snowflakes drifted on to the chamber's floor. From this point it was easy to expand the process to full, outdoor...
