• That narrow stretch of sand knows nothing in the world better than it does the white waves that whip it , caress it , collapse on to it . The white foam knows nothing better than those sands which wait for it , rise to it and suck it in .but what do the waves know of the massed, hot, still sands of the desert just twenty , no , ten feet beyond the scalloped edge ? And what does the beach knows of depths, the cold, the currents just there, where-do you see it? - Where the water turns a deeper blue.
