  子墨子曰:“荆之地方五千里,宋之地方五百里,此犹文轩之与敝舆也。荆有云梦,犀兕麋鹿满之,江汉之鱼鳖鼋鼍为天下富,宋所谓无雉兔鲋鱼者也,此犹粱肉之与糠糟也。荆有长松文梓楩楠豫章,宋无长木,此犹锦绣之与短褐也。臣以王吏之攻宋也,为与此同类。”

  王曰:“善哉。虽然,公输盘为我为云梯,必取宋。”

  于是见公输盘。子墨子解带为城,以牒为械。公输盘九设攻城之机变,子墨子九距之。公输盘之攻械尽,子墨子之守国有余。

  公输盘诎,而曰:“吾知所以距子矣,吾不言。”

  子墨子亦曰:“吾知子之所以距我,吾不言。”

  楚王问其故。

  子墨子曰:“公输子之意不过欲杀臣。杀臣,宋莫能守,乃可攻也。然臣之弟子禽滑厘等三百人,已持臣守圉之器,在宋城上而待楚寇矣。虽杀臣,不能绝也。”

  楚王曰:“善哉。吾请无攻宋矣。”

     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."
