When Jemima is older, Leonard begins to attempt to impose his own values on her. He has become more fastidious and less appreciative of her interests.

When she goes to live with him, he gives her a cabinet to put treasures in, but they each have different ideas about what is suitable. She produces what she thinks of as natural history specimens but he sees it as rubbish and makes her throw it away.

As a gesture of rebellion she later took the bag out of the bin and hid it under her bed. Not only that; she added further objects to the collection as she found them: rabbit and bird skulls, feathers, leaf skeletons, pine cones gnawed this time by squirrels (a different pattern), hazel nuts opened by mice, conkers, more fungi.
