Throughout his years at school, Kim remains in contact with the holy man he has come to love. Kim also retains contact with his secret service connections and is trained in espionage (to be a surveyor) while on vacation from school by Lurgan Sahib, a sort of benevolent Fagin, at his jewellery shop in Simla. As part of his training, Kim looks at a tray full of mixed objects and notes which have been added or taken away, a pastime still called Kim's Game, also called the Jewel Game. Other parts of this training are disguise and the careful study of Indian population, and the characteristic dress, behaviour and "even how they spit" in order to go undercover or to discover those in disguise.
