(a). The Indau River. — 



This river has been described in a previous number of this 

 Journal ; I will therefore only deal with two of its tributaries 

 not previously explored, viz., the Mas and the Lemakan rivers. 



SuNGEi Mas.— 



The source of this river lies in some low hills to the west 

 of the Indau ; the stream, after pursuing a E. N. E. course, 

 empties itself into the upper Indau, eleven miles above Kuala 

 Sembrong. Total length of river about twenty -five miles. 



The Mas is very shallow and can only be ascended in small 

 canoes. Six and a half miles up stream there is a Jakun village 

 consisting of three large huts with about twenty-five inhabitants 

 under a Jeroh Kerah. Two and a half miles further there is a 

 larger settlement of fifty to sixty people, under a Batin. Most 

 of the aborigines are engaged in rotan and getah collecting, they 

 also plant tapioca and Indian corn (jagong) 



There were several cases of leprosy here. 



SuNGEi Lemakan.— 



This a small river having its source amongst the southern 

 spurs of Mount Janeng ; its general course is north easterly. 

 Total length about nine miles. It joins the Upper Indau
