Ralph came up with an idea to create a sundial so they can tell what time is, but then he then seems to think wildly and say they could make an ‘airplane, and a TV set’ it seems that he’s paranoid and wants to leave the island as soon as possible. The boys seem to have seen a ship and they try their best to get its attention but they seem to fail,’he was leaning forward and the salt was whitening his body’ this quotation is saying that he was so desperate to get off the island that he stayed in the water for long.
