What does Ralph want to go talk to Jack dressed like in Lord of the Flies chapter 11?

Ralph suggested that they should go to castle rock , and I quote... "looking like we used to, washed and hair brushed-- after all we aren't savages really and being rescued isn't a game--" Ralph hopes that by appearing dressed and clean he can remind the boys who are aligned with Jack that they are not really violent savages at all but that they are really civilised English schoolboys, who should conform to the rules of civilised society. He also wants to remind them by his appearance that not only did they come from England but that their only hope of ever returning there is if they are rescued, which they can only hope to achieve if they maintain a signal fire.
