Today North Beach was filled with seaweed of every color of the rainbow, all except for blue. Some of these seaweeds were smooth and flexible, some stiff and brittle, some soft and spongy, some so delicate I was surprised they had survived the waves at all. I gathered a few and arranged them on the granite, remembering how the French compose their elegant salads. Yes, I had made a Salade Composée! And later, inside an empty mussel shell, I did find several shades of blue.
