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.
