I am sitting on a wooden bench seat on a pebble beach, face towards the sea in a high wind, beside a boulder carved from worthy motives to a shape that fails to lift my spirits, make that famous surge of pure adrenalin. It sits there, squat, sufficient in its heft, its small brass plate a telling of the fact that off this beach the well-known harbour - Mulberry - was born.* A few weeks. Fifty sections, each of some six thousand tons. I've often wondered how the German spotter planes could miss so much. The plaque explains: the builders sank each piece as it was finished. One would not refloat. It lies there, visible at each low tide. A young man pushes a twin buggy round from six O'clock, almost collapses on the far end of the seat. Falls forward, head resting on the handle of the buggy. Fast asleep - while tucked inside, two twin boys, identical, are also sound asleep. From 4 O'clock two more young men. Also in charge of twins. Two more identical. The men themselves the same. Three pairs in all, so something in the world's great scheme of things, its hidden depths, is working its self out! The new (child) twins are older boys. Lower infants, I would guess. They carry buckets full of bits: short lengths of wood, match boxes, twigs and paper cups, boat shapes and plastic items which they take down to the sea to float them there. On each occasion though, the large waves sink or swamp them and they pick them from the water run up to the rock, climb on, and lay their treasues in the sun - to dry! The high wind promptly blows them off. They weight them then with pebbles or with sand and try to fit them to each other. Like maybe they are jig-saw bits. I fantasize now. Are they building their own Mulberry... but no, it doesn't work. End! cries one. They sweep the boulder clean and run back to the men. The man beside me rises, walks away to 9 O'clock. The other two - at that exact same moment - turn, depart the way they'd come, but stooping. Flicking pebbles. The pebbles fail to skim. The waves must always have the final word.
