In Aunt Tilley's house, Kyla and E.B. investigate random objects in the file drawers they inherited from Great Aunt Hermione that show how history connects to who we are and how we live now. What's the difference between working animals and pets? Kyla visits a blacksmith at a re-created 19th century village where she learns how horses provided transportation, plowed fields and did many other kinds of work. Dogs also used to work as hunters and for transportation. And carrier pigeons were used to send messages for thousands of years until they were replaced by modern technologies. Now, dogs, horses and pigeons are kept mostly for recreation.
