Slide and Seethe
As I stand on my dune top, however, I do not think of the illusion and the beat of earth, for I watch the waves with my outer rather than my inner eye. After all, the illusion is set off by an extraordinary, an almost miraculous thing—the embodiment of the wave beat in an almost constant shape. We see a wave a quarter of a mile off, then a few hundred yards nearer in, then just offshore; we seem to have been watching the same travelling mass of water—there has been no appreciable change in mass or in shape—yet all the while the original beat has taken on a flowing series of liquid bodies, bodies so alike, so much the same, that our eye will individualize them and follow them in—the third wave, we say, or the second wave behind the great wave. How strange it is that this beat of earth, this mysterious undulation of the seas, moving through and among the other forces stirring the waters close off the continent, should thus keep its constancy of form and mass, and how odd a blend of illusion and reality it all is! On the whole, the outer eye has the best of it.
Blowing all day long, a northwest wind yesterday swept the sky clear of every tatter and wisp of cloud. Clear it still is, though the wind has shifted to the east. The sky this afternoon is a harmony of universal blue, bordered with a surf rim of snowiest blue-white. Far out at sea, in the northeast and near the horizon, is a pool of the loveliest blue I have ever seen here—a light blue, a petal blue, blue of the emperor’s gown in a Chinese fairy tale. If you would see waves at their best, come on such a day, when the ocean reflects a lovely sky, and the wind is light and onshore; plan to arrive in the afternoon so that you will have the sun facing the breakers. Come early, for the glints on the waves are most beautiful and interesting when the light is oblique and high. And come with a rising tide.
The surf is high, and on the far side of it, a wave greater than its fellows is shouldering out of the blue, glinting immensity of sea.
Friends tell me that there are certain tropic beaches where waves miles long break all at once in one cannonading crash: a little of this, I imagine, would be magnificent; a constancy of it, unbearable. The surf here is broken; it approaches the beach in long intercurrent parallels, some a few hundred feet long, some an eighth of a mile long, some, and the longest, attaining the quarter-mile length and perhaps just over. Thus, at all times and instants of the day, along the five miles of beach visible from the Fo’castle deck, waves are to be seen breaking, coursing in to break, seething up and sliding back.
But to return to the blue wave rolling in out of the blue spaciousness of sea. On the other side of the world, just opposite the Cape, lies the ancient Spanish province of Galicia, and the town of Pontevedra and St. James Compostella, renowned of pilgrims. (When I was there they offered me a silver cockle shell, but I would have none of it, and got myself a sea shell from some Galician fisherfolk.) Somewhere between this Spanish land and Cape Cod the pulse of earth has engendered this wave and sent it coursing westward through the seas. Far off the coast, the spray of its passing has, perhaps, risen on the windward bow of some rusty freighter and fallen in rainbow drops upon her plates; the great liners have felt it course beneath their keels.
A continent rises in the west, and the pulse beat approaches this bulwark of Cape Cod. Two thirds of a mile out, the wave is still a sea vibration, a billow. Slice it across, and its outline will be that of a slightly flattened semi-circle; the pulse is shaped in a long, advancing mound. I watch it approach the beach. Closer and closer in, it is rising with the rise of the beach and the shoaling of the water; closer still, it is changing from a mound to a pyramid, a pyramid which swiftly distorts, the seaward side lengthening, the landward side incurving—the wave is now a breaker. Along the ridge of blue forms a rippling crest of clear, bright water; a little spray flies off. Under the racing foam churned up by the dissolution of other breakers the beach now catches at the last shape of sea inhabited by the pulse—the wave is tripped by the shoaling sand—the giant stumbles, crashes, and is pushed over and ahead by the sloping line of force behind. The fall of a breaker is never the work of gravity alone.
It is the last line of the wave that has captured the decorative imagination of the world—the long seaward slope, the curling crest, the incurved volute ahead.
