Since the chips from Talap’s boat had floated only as far as Bangai, he and his descendants could claim only the lands on the right bank of the Layar from Nanga Ban to that point.
After Patinggi Ngadan had lived at Bangai for some years, he decided to move further up the river to Batu Lintang. At that place he placed a belian tree to show the boundary between his land and those of Sampar of Penebak in Ulu Layar.
The belian tree still stand as of today and is known as Tras Tangkal Patinggi, which means the belian tree notched by Patinggi. However, after Patinggi has placed the marker, he heard that Sampar was planning to migrate down river from Ulu Layar. He warned Sampar that if he were to move into the area below the boundary, it would mean war. To show his seriousness, Patinggi Ngadan hung a basket (ringka) at a tree at the mouth of the stream above his landing stage. It was meant to keep Sampar’s head in it if the latter dared to ignore his warning. Today, the stream is known as Sungai Ringka.
A few weeks later, after Patinggi learned that Sampar has dropped his plans to migrate, he went back down the river to live at Nanga Jaloh. He and his descendants still claimed all the land up to the belian boundary marker.
Shortly after Patinggi Ngadan moved to Nanga Jaloh, his son Labun left and built a new house at Nanga Lupa not very far down stream. Later the people at Labun and his father longhouses held a great cockfighting contest. The ghost of one of the birds killed in the contest was seen to fly skywards and disappear. Not long after that a large bird flew over the longhouse roof and kicked the end of its ridge pole. On the following night, Patinggi Ngadan had a dream. In his dream he met the spirit of the cock who told him that since many cocks had been cruelly killed during the contest, he and his son and all of their people would also suffer a cruel death.
Some days after that, a small pox epidemic struck both of the longhouses. Many people died that no one could bury all the bodies in the cemetery. Thus both of the longhouses themselves became the burial grounds, which is known today as Pendam Lupa and Pendam Jaloh. It was not known whether the virus infected Patinggi Ngadan and his son Labun.
