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.
Lakes and Rivers. Very few lakes are easily accessible in Yosemite National Park. Tenaya Lake (above) is one of the easiest to get to (when the Tioga Road is open, late May or early June to sometime in November) and is quite popular for picnicking, swimming, and canoeing. You can see Tenaya Lake from Olmsted Point and as you drive past it.
