What is the sign that jim is maturing in treasure island.

James "Jim" Hawkins is a fictional character in Robert Louis Stevenson's novel Treasure Island. He is both the protagonist and narrator of the story.Jim Hawkins is the young son of the owners of the Admiral Benbow Inn. An old drunken seaman named Billy Bones becomes a long-term lodger at the inn. Jim quickly realizes that Bones is in hiding, and that he particularly dreads meeting an unidentified seafaring man with one leg. Bones is visited by his crewmates twice during the following months, the second visit being by Pew, who gives Bones the Black Spot, a pirates' summons, with the warning that he has until ten o'clock, and he drops dead of apoplexy on the spot. Jim and his mother open Bones' sea chest to collect the amount due for Bones's room and board, but before they can count out the money due them, they hear pirates approaching the inn and are forced to flee and hide, Jim taking with him a mysterious oilskin packet from the chest. Jim comes to the house of local landowner Squire Trelawney and his mother's friend and patron Dr. Livesey. Together, they examine the oilskin packet, which contains a logbook detailing the treasure looted during Captain Flint's career, and a detailed map of an island, with the location of Flint's treasure caches marked on it. Squire Trelawney immediately plans to outfit a sailing vessel to hunt the treasure down, with the help of Dr. Livesey and Jim.
