The father of five children had won a toy at a raffle.
He called his kids together to ask which one should have the present.
"Who is the most obedient?" he asked. "Who never talks back to mother? Who does everything she says?"
Five small voices answered in unison. "Okay, dad, you get the toy."
CarborundumIn 1893, carborundum was patented by Edward G. Acheson of Monongahela, Penn. He had discovered it accidentally while trying to make artificial diamonds. He had dissolved carbon into molten corundum (a mixture of powdered coke and clay) in an electric furnace, and that yielded dark, hard, gritty crystals. He named the new material carborundum, and found it was one of the hardest industrial substances (second only to diamond), which made it an excellent abrasive material. In 1894, he started the Carborundum Company in Monongahela to produce grindstones, knife sharpeners, and various abrasives. Later, on 19 May 1896, obtained a patent for an electric furnace, suitable for making carborundum.« |
