And now, by the flashes of the lightning, Tom saw a new sight—all the bottom of the stream alive with great eels, turning and twisting along, all down stream and away. They had been hiding for weeks past in the cracks of the rocks, and in burrows in the mud; and Tom had hardly ever seen them, except now and then at night: but now they were all out, and went hurrying past him so fiercely and wildly that he was quite frightened. And as they hurried past he could hear them say to each other, “We must run, we must run. What a jolly thunderstorm! Down to the sea, down to the sea!” And then the otter came by with all her brood, twining and sweeping along as fast as the eels themselves; and she spied Tom as she came by, and said “Now is your time, eft, if you want to see the world. Come along, children, never mind those nasty eels: we shall breakfast on salmon to-morrow. Down to the sea, down to the sea!” [Picture: Tom with the eels] Then came a flash brighter than all the rest, and by the light of it—in the thousandth part of a second they were gone again—but he had seen them, he was certain of it—Three beautiful little white girls, with their arms twined round each other’s necks, floating down the torrent, as they sang, “Down to the sea, down to the sea!” “Oh stay! Wait for me!” cried Tom; but they were gone: yet he could hear their voices clear and sweet through the roar of thunder and water and wind, singing as they died away, “Down to the sea!” “Down to the sea?” said Tom; “everything is going to the sea, and I will go too. Good-bye, trout.” But the trout were so busy gobbling worms that they never turned to answer him; so that Tom was spared the pain of bidding them farewell. And now, down the rushing stream, guided by the bright flashes of the storm; past tall birch-fringed rocks, which shone out one moment as clear as day, and the next were dark as night; past dark hovers under swirling banks, from which great trout rushed out on Tom, thinking him to be good to eat, and turned back sulkily, for the fairies sent them home again with a tremendous scolding, for daring to meddle with a water-baby; on through narrow strids and roaring cataracts, where Tom was deafened and blinded for a moment by the rushing waters; along deep reaches, where the white water-lilies tossed and flapped beneath the wind and hail; past sleeping villages; under dark bridge-arches, and away and away to the sea. And Tom could not stop, and did not care to stop; he would see the great world below, and the salmon, and the breakers, and the wide wide sea. And when the daylight came, Tom found himself out in the salmon river.
