In Chapter 35, Tom and Huck are planning what the best way to rescue Jim is. As they are designing their plan, Tom begins to think of the way rescue plans are carried out in books. He then comes up with several possible ideas, all of them strange and risky. He believes they need a rope ladder and a moat. He also thinks they need a diary written with blood. The plan that shocks Huck the most is the fact that Tom thinks they should saw Jim's leg off to help him escape.
