In The Cay, what is the description of the island?

When Timothy and Phillip approach the island in Chapter Six of The Cay, Timothy must describe it to Phillip, as Phillip has gone blind. Timothy describes it as a small, uninhabited island. There is a beautiful white beach and low sea-grape bushes. About twenty to thirty palm trees grow on the hill. When they land on the island in Chapter Seven, Timothy describes the cay as quite beautiful, populated with native lobsters he refers to as "langosta." After Timothy walks around the island, he tells Phillip that the only things on the island are the beach, the sea-grape bushes, the palm trees, and some little lizards. There is no fresh water source. Timothy describes the island as one mile long and one-half mile wide and says that it is shaped like a melon. The rise with the palm trees is about forty feet from the ocean.
