"I shall not forget," said Gil.

Again they looked at the Sea-child, and he had fallen sound asleep, still holding Gil's hand. Now there was scarcely anything of the fish left about his little pink body; he was growing younger and younger, smaller and smaller.

"You must go home now, Gil," said the Stork. "Go home and go to bed. And to-morrow when you wake there will be a little brother in the house, and you ought to be a very good boy because you have your wish."

Gil gently loosened the Sea-child's hand and ran home as the Stork bade him, but said no word of all this to any one.

Now early in the morning the Stork came to the house on the hill, bringing a rosy little new baby which he laid on the bed beside Gil's mother, and then flew away. What a hullabaloo there was then, to be sure! What a welcome for the little stranger! Gil was not the only one who had longed for a new baby in the house, and this was the prettiest little fellow ever seen. Loudest of all cheered Gil when he saw the present which the Stork had brought. "Hurrah for my little new brother!" he cried. "Now I shall have some one to play with." That was Gil's chief thought: now he would have some one to play with.

They called the baby's name Jan. And from the first little Jan was very happy in his new home. He was happy all day in his mother's arms; happy when his foster-father came home at night and tossed him high to the ceiling; happiest of all when Gil held him close and begged him to hurry and grow up, so that they could play together.

Little Jan did hurry to grow up, as fast as health and strength and happiness could make a baby grow. He grew bigger and bigger, handsomer and handsomer, the finest baby in the village, and his family loved him dearly. Every day he became more of a playmate for Gil, whom he admired more than any one in the world. Gil petted and teased the little fellow, who, as soon as he could walk, began to follow him about like a faithful dog. Grand times the brothers had together then. They dug in the sand on the seashore, and scrambled about the cliffs. They rowed out in the harbor boats with hooks and lines, and played at being fishermen like their father, who sailed away early and came home late. They grew bigger and sturdier and handsomer, and their parents were very proud of them both, the finest lads in all the country round.

The years went by, and during all this time Jan never dreamed the truth which only Gil and the Stork knew about the bargain made at the sea-pool cradle. To Jan, indeed, the sea was full of strange thoughts which were not memories but were like them. He loved to look and listen alone upon the water, or in the water, or by the water. Gil often caught him staring down into the blue waves, and when he raised his head there would be a puzzled look in the little fellow's blue eyes, as though he were trying to solve a riddle. Then Gil would laugh; whereat the wrinkle would smooth itself from Jan's forehead, and a smile would come about his mouth. He would throw his arm about his brother's shoulder, saying,—

"What strange thing is it, brother, that the old sea does to me? I think sometimes that I am bewitched." But Gil would only laugh again, thinking his own thoughts. It gave him a pleasant important feeling to know that he was the keeper of Jan's secret.

Meantime what had become of the Sea-baby's forgotten mother? What was the pretty Mermaid doing in her home under the waves? She was learning the lesson which the Stork had meant to teach.
