A few days later, after school has begun for the year, Jem tells Scout that he found the pants mysteriously mended and hung neatly over the fence. When they come home from school that day, they find another present hidden in the knothole: a ball of gray twine. They leave it there for a few days, but no one takes it, so they claim it for their own.
Unsurprisingly, Scout is as unhappy in second grade as she was in first, but Jem promises her that school gets better the farther along one goes. Late that fall, another present appears in the knothole—two figures carved in soap to resemble Scout and Jem. The figures are followed in turn by chewing gum, a spelling bee medal, and an old pocket watch. The next day, Jem and Scout find that the knothole has been filled with cement. When Jem asks Mr. Radley (Nathan Radley, Boo’s brother) about the knothole the following day, Mr. Radley replies that he plugged the knothole because the tree is dying.
