When Kruesi finished making the phonograph Edison put on the tin foil and then recorded the nursery rhyme Mary Had a Little Lamb; Edison's daughter Marion was at the time nearly five years old and his eldest son was almost two. Edison then adjusted the reproducer and the machine reproduced it perfectly.
Spring in Yosemite National Park. Spring is by far the best time to visit Yosemite Valley. In May the waterfalls are at their peak, the wildflowers are blooming, and the summer crowds have not yet arrived. Daytime temperatures are often divine, but be prepared for chilly temperatures at night.
Yosemite National Park covers nearly 1,200 square miles of mountainous terrain in the Sierra Nevada of California. Yosemite is open all year, though some areas of the park are inaccessible by car from approximately November through May due to snow. You can drive your car into and around Yosemite, though we encourage you to use shuttles in some areas.
