When Mabel's Father hears a knock at the door, he puts his bottle into the book and leaves the book on the table, overhanging the edge. After answering the door and bring the Squire's Son into the room, the book has disappeared.
When Mabel is stuck in the tree, the squire's son fetches some rope to help her down. He appears with rope in hand, without a hat. The scene then cuts to him walking over to the tree with the rope, only now he's wearing a hat.
