A little past noon he began to hear a low murmuring sound that seemed in the earth beneath him, and all about him, and in the air above him; but he did not know that it was the sound of the sea. At length he came to a place where the earth rose up in long ridges of yellow sand, on which nothing grew but scattered tufts of stiff, yellow grass. As he toiled over the loose sand, sometimes sinking ankle-deep in it, the curious deep murmuring sound he had heard for so long grew louder and louder, until it was like the sound of a mighty wind in a wood, but deeper and hoarser, rising and falling, and at intervals broken by great throbs, as of thunder echoed and re-echoed among the distant hills. At length he had toiled over the last ridge of sand; and then all at once the world--his world of solid earth at all events--came to an abrupt end; for no more ground on which to set a foot was before him, but only the ocean--that ocean which he had wanted so badly, and had loved at a distance more than the plains and hills, and all they contained to delight him! How wide, how vast it was, stretching away to where it melted into the low sky, its immense grey-blue surface broken into ten thousand thousand waves, lit with white crests that came in sight and vanished like lightning flashes! How tremendous, how terrible it was in its agitation--O the world had nothing to compare with it, nothing to hold his heart after it; and it was well that the earth was silent, that it only gazed upon it with the sun and moon and stars, listening day and night for ever to the great voice of the sea!
