So they worked away at the rock, and planted it, and smoothed the sand down round, it, and capital fun they had till the tide began to turn. And then Tom heard all the other babies coming, laughing and singing and shouting and romping; and the noise they made was just like the noise of the ripple. So he knew that he had been hearing and seeing the water-babies all along; only he did not know them, because his eyes and ears were not opened.
And in they came, dozens and dozens of them, some bigger than Tom and some smaller, all in the neatest little white bathing dresses; and when they found that he was a new baby, they hugged him and kissed him, and then put him in the middle and danced round him on the sand, and there was no one ever so happy as poor little Tom.
"Now then," they cried all at once, "we must come away home, we must come away home, or the tide will leave us dry. We have mended all the broken sea-weed, and put all the rock-pools in order, and planted all the shells again in the sand, and nobody will see where the ugly storm swept in last week."
And this is the reason why the rock-pools are always so neat and clean; because the water-babies come inshore after every storm to sweep them out, and comb them down, and put them all to rights again.
Only where men are wasteful and dirty, and let sewers run into the sea instead of putting the stuff upon the fields like thrifty reasonable souls; or throw herrings' heads and dead dog-fish, or any other refuse, into the water; or in any way make a mess upon the clean shore - there the water-babies will not come, sometimes not for hundreds of years (for they cannot abide anything smelly or foul), but leave the sea-anemones and the crabs to clear away everything, till the good tidy sea has covered up all the dirt in soft mud and clean sand, where the water-babies can plant live cockles and whelks and razor-shells and sea-cucumbers and golden- combs, and make a pretty live garden again, after man's dirt is cleared away. And that, I suppose, is the reason why there are no water-babies at any watering-place which I have ever seen.
And where is the home of the water-babies? In St. Brandan's fairy isle.
Did you never hear of the blessed St. Brandan, how he preached to the wild Irish on the wild, wild Kerry coast, he and five other hermits, till they were weary and longed to rest? For the wild Irish would not listen to them, or come to confession and to mass, but liked better to brew potheen, and dance the pater o'pee, and knock each other over the head with shillelaghs, and shoot each other from behind turf-dykes, and steal each other's cattle, and burn each other's homes; till St. Brandan and his friends were weary of them, for they would not learn to be peaceable Christians at all.
So St. Brandan went out to the point of Old Dunmore, and looked over the tide-way roaring round the Blasquets, at the end of all the world, and away into the ocean, and sighed - "Ah that I had wings as a dove!" And far away, before the setting sun, he saw a blue fairy sea, and golden fairy islands, and he said, "Those are the islands of the blest." Then he and his friends got into a hooker, and sailed away and away to the westward, and were never heard of more. But the people who would not hear him were changed into gorillas, and gorillas they are until this day.
And when St. Brandan and the hermits came to that fairy isle they found it overgrown with cedars and full of beautiful birds; and he sat down under the cedars and preached to all the birds in the air.
And they liked his sermons so well that they told the fishes in the sea; and they came, and St. Brandan preached to them; and the fishes told the water-babies, who live in the caves under the isle; and they came up by hundreds every Sunday, and St. Brandan got quite a neat little Sunday-school. And there he taught the water- babies for a great many hundred years, till his eyes grew too dim to see, and his beard grew so long that he dared not walk for fear of treading on it, and then he might have tumbled down. And at last he and the five hermits fell fast asleep under the cedar- shades, and there they sleep unto this day. But the fairies took to the water-babies, and taught them their lessons themselves.
And some say that St. Brandan will awake and begin to teach the babies once more: but some think that he will sleep on, for better for worse, till the coming of the Cocqcigrues. But, on still clear summer evenings, when the sun sinks down into the sea, among golden cloud-capes and cloud-islands, and locks and friths of azure sky, the sailors fancy that they see, away to westward, St. Brandan's fairy isle.
But whether men can see it or not, St. Brandan's Isle once actually stood there; a great land out in the ocean, which has sunk and sunk beneath the waves. Old Plato called it Atlantis, and told strange tales of the wise men who lived therein, and of the wars they fought in the old times. And from off that island came strange flowers, which linger still about this land:- the Cornish heath, and Cornish moneywort, and the delicate Venus's hair, and the London-pride which covers the Kerry mountains, and the little pink butterwort of Devon, and the great blue butterwort of Ireland, and the Connemara heath, and the bristle-fern of the Turk waterfall, and many a strange plant more; all fairy tokens left for wise men and good children from off St. Brandan's Isle.
