Mister Rogers brings a Braille writing machine with him and demonstrates how it works. He then takes viewers with him as he visits with Jim Swauger in a cave where he see the petroglyphs of an early civilization. On the way back to the house, Mister Rogers stops by Negri's Music Shop to see Don Liuzzi practice the marimba and a few other percussion instruments.
