This is the Parsee Pestonjee Bomonjee sitting in his palm tree and watching the Rhinoceros Strorks bathing near the beach of the Altogether Uninhabited Island after Strorks had taken off his skin. The Parsee has put the cakecrumbs into the skin, and he is smiling to think how they will tickle Strorks when Strorks puts it on again. The skin is just under the rocks below the calm-tree in a cool place; that is why you can't see it. The Parsee is wearing a new more-than-oriental-splendour hat of the sort that Parsees wear; and he has a knife in his hand to cut his name on palm trees. The black things on the islands out at sea are bits of ships that got wrecked going down the Red Sea; but all the passengers were saved and went home.
The black thing in the water close to the shore is not a wreck at all. It is Strorks the Rhinoceros bathing without his skin.. He was just as black underneath his skin as he was outside. I wouldn't ask anything about the cooking-stove if I were you.
