Lost and Found

S1, E5: On Block Island, look for the glass orbs that a local artist makes and tucks away for anyone to discover. Next stop: an orchard paradise in Dummerston, Vermont, filled with heirloom apples that can be traced back to the earliest days of American history. Finally, visit Boston's Isabella Stewart Gardner Museum, home to a priceless art collection amassed by one of Boston's most unorthodox patrons.
