Algy decided to move onto the rocks for a spot of chilly sunbathing. The amazing colours of the water in the bay reminded him of a poem he used to love when he was just a wee chick, except that here the jewels were in the sea itself:

            Stately Spanish galleon coming from the Isthmus,
            Dipping through the Tropics by the palm-green shores,
            With a cargo of diamonds,
            Emeralds, amythysts,
            Topazes, and cinnamon, and gold moidores.

[Algy is quoting the middle verse of the poem Cargoes by John Masefield.]
