   Once, Louis the Twelfth, the King of France, happened to walk into the kitchen of his palace. There he found a small boy busy at work and singing happily.

   The boy had bright eyes, and a happy, sunny face, and his looks and manners pleased the king. With a smile Louis asked him his name. He replied that his name was Simon. In answer to further questions, the king learnt that the boy was an orphan; both his father and mother were dead.

   “Are you content（满足的）to do this kind of work?” the king asked, pointing at the bowls which the boy was washing. “Are you willing to spend your time in the kitchen when so many of the others work upstairs?”

   “Why not?” answered the boy, with a twinkle in his eye. “I am doing as well as the best of them. The king himself can do no better.”

   “Indeed!” said the king, no little surprised at the boy's words. “How do you know that?”

   “Well, sir, the king lives, and so do I. I am content with my life. Can the king say that he is content with his life?”

   Louis walked away, his mind full of strange, sad thoughts. No one knew better than he did that kings seldom feel content.

   The next day, much to Simon's surprise, he was called before the king. He was still more surprised when he found that his visitor of the day before was Louis himself. The king talked with him about many things, and found him to be a very quick and clever boy.

   After that Simon was made to serve the king directly. Step by step, he rose from one important task to another, until he became one of the best soldiers of that time. He is known in his history as General La Roche, and considered as one of the greatest men of France.

   If Simon had not, early in life, learnt to be content with his life, he might never have been given those chances. The king did not want people who were always unhappy because they did not have as good a place as some others. You cannot too soon learn that only those who are content are happy.

    He was the baby with no name. Found and taken from the north Atlantic 6 days after the sinking of the Titanic in 1912, his tiny body so moved the salvage (救援) workers that they called him “our baby.” In their home port of Halifax, Nova Scotia, people collected money for a headstone in front of the baby's grave (墓), carved with the words: “To the memory of an unknown child.” He has rested there ever since.

    But history has a way of uncovering its secrets. On Nov. 5, this year, three members of a family from Finland arrived at Halifax and laid fresh flowers at the grave. “This is our baby,” says Magda Schleifer, 68, a banker. She grew up hearing stories about a great-aunt named Maria Panula,42, who had sailed on the Titanic for America to be reunited with her husband. According to the information Mrs. Schleifer had gathered, Panula gave up her seat on a lifeboat to search for her five children -- including a 13-month-old boy named Eino from whom she had become separated during the final minutes of the crossing. "We thought they were all lost in the sea," says Schleifer.

    Now, using teeth and bone pieces taken from the baby's grave, scientists have compared the DNA from the Unknown Child with those collected from members of five families who lost relatives on the Titanic and never recovered the bodies. The result of the test points only to one possible person: young Eino. Now, the family sees no need for a new grave. "He belongs to the people of Halifax," says Schleifer, "They've taken care of him for 90 years."
