Scope and Contents:
Time on Our Hand The development of timekeeping, from sundials to clocks, watches, chronometers and even atomic clocks has depended on advances in technology. Glass pitchers are formed and decorated on an assembly line; parts of furniture are cut by machine and then the craftsman puts the furniture together; quick drying lacquer on automobiles saves production time. Housewives save time by using kitchen appliances, especially a dishwasher. Through mechanization Americans have more leisure time and can enjoy such activities as riding the cog railroad to the top of Mount Washington, NH.
