August 9, 1938. Washington, D.C. "Air conditioned hen house is latest. Biddy increases the production of eggs in an air-conditioned hen house, U.S. Department of Agriculture experts have discovered after extensive experiments. The first temperature controlled maternity ward for hens has just been put into operation at the governmental experimental farm here. The hens have voiced their approval by laying more frequently; also a more uniform egg. R.B. Nestler, poultry expert, is pictured as he removes the eggs from the automatic chute in the new room. Note the air conditioning apparatus on the ceiling." So this poultry man with the wonderful name of Nestler is, contrary to USDA Best Practices, putting all his eggs in one basket.

The sort of parade seen here was, by the early 20th century, an Anglo attempt to celebrate the city’s deeply Hispanic past with a a faux Mexican Spanish fiesta. The message was, pay tribute, but don’t mingle.”
Orson Welles on the Air
Before the television became a fixture in every home, Americans gathered ’round the radio for their entertainment, to hear thrilling stories and wacky jokes and toe-tapping tunes. Among the best radio entertainers of his time was actor Orson Welles, who was so convincing during his stylized 1938 reading of H.G. Wells’ aliens-on-Earth story The War of the Worlds that his rapt, terrified audience believed the fiction to be true.
