He had been very stupid all day, and so had the trout; for they would not move an inch to take a fly, though there were thousands on the water, but lay dozing at the bottom under the shade of the stones; and Tom lay dozing too, and was glad to cuddle their smooth cool sides, for the water was quite warm and unpleasant.

But toward evening it grew suddenly dark, and Tom looked up and saw a blanket of black clouds lying right across the valley above his head, resting on the crags right and left. He felt not quite frightened, but very still; for everything was still. There was not a whisper of wind, nor a chirp of a bird to be heard; and next a few great drops of rain fell plop into the water, and one hit Tom on the nose, and made him pop his head down quickly enough.

And then the thunder roared, and the lightning flashed, and leapt across Vendale and back again, from cloud to cloud, and cliff to cliff, till the very rocks in the stream seemed to shake: and Tom looked up at it through the water, and thought it the finest thing he ever saw in his life.

But out of the water he dared not put his head; for the rain came down by bucketsful, and the hail hammered like shot on the stream, and churned it into foam; and soon the stream rose, and rushed down, higher and higher, and fouler and fouler, full of beetles, and sticks; and straws, and worms, and addle-eggs, and wood-lice, and leeches, and odds and ends, and omnium-gatherums, and this, that, and the other, enough to fill nine museums.

Tom could hardly stand against the stream, and hid behind a rock. But the trout did not; for out they rushed from among the stones, and began gobbling the beetles and leeches in the most greedy and quarrelsome way, and swimming about with great worms hanging out of their mouths, tugging and kicking to get them away from each other.

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!”

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!”
