How is the island described in chapters 13-15 of treasure island?

The weather is sweltering when the ship approaches the island. The crew is clearly discontent and irritable. Dr. Livesay tells the men that they could be at risk of contracting tropical diseases while on the island. As Silver has an excellent knowledge of the geography of the island, he tells Captain Smollett of a suitable place for dropping anchor. Smollett hides his knowledge of the planned mutiny. After he has consulted with Trelawney, he decides that he will let the crew go ashore for some diversion. This will let the honest men take back control of the ship.

Smollett brings Tom Redruth and a number of other sailors into his confidence. He provides them with weapons. Silver brings the pirates ashore, assuming that they will be able to take the treasure right away. Jim decides that his help is not required on board. He conceals himself in one of the pirates’ boats so that he can go ashore with them. Silver sees Jim, however, and the latter starts to regret his plan. Jim gets to the shore before the others and runs away from them quickly.

the words "slavery," "devils," and "murderer" evoke a sense of disgust.

choices ? or is this a actual question from yourself ?
