As Demong grow older and knew that the time of his death is approaching, he made a plan to safeguard the interest of all his children – those of his Iban wife as well as those of his Bukitan wife. He erected a stone at a place called Nanga Entaih not far from the mouth of the Awas River in Upper Krian as a landmark for his children.
He ordered that the stone served as a boundary marker between the lands which would be inherited by the children of his first wife (the Ibans) and those, which would be inherited by the children of his second wife (the Bukitans). According to this settlement Rinda’s children (who claimed themselves as Iban) would own the old land lying from Paku River and Upper Krian as far as the erected stone only. While the children of Lemia (who of course a pure Bukitan) would own the new land lying from the stone towards the Julau and Rejang Rivers.
However, while the first group (Iban) was allowed to pass beyond the stone, the second group (Bukitan) was not allowed to turn back towards the old lands.
This stone of Demong is still intact and the Demong’s ruling on the division of land is still followed down to the present day. People from Paku and Krian have gone over to the Rejang but not one from the Rejang has ever returned to the former land.
It was during these early days, during the life of the sons of Demong, that another pioneer came to Paku and made contact with the people of the coast who at this time were not yet Muslim but who later became the Malays of Saribas. The name of this pioneer was Rusak. He came from the Undup and was was the grandson of the Undup chief named Jelian.
