What nicknames are established for Chip and Miles in "one hundred twenty-eight days before"? What other information does Chip share with Miles in this chapter?

Chip and Miles go out and sit by the lake, where Chip tells Miles to call him the Colonel, gives him a nickname of his own (Pudge, ironic because of Miles' skinniness), and warns him against several things - in particular, telling on fellow students who've broken the rules, and offending the strict teacher and dorm supervisor, Mr. Starnes (nicknamed "the Eagle").
