A JOURNEY TO THE SOURCE OF THE INDAU. 5 



■ Gn August 2 1st, I left Batu Gajah and proceeded up-steam, 

 accompanied by 4 Malays and 15 Jakuns in a dozen small 

 jalors. Personal baggage and equipment was cut down to a 

 very few pounds in order to enable us to carry sufficient rice 

 to last a month at least. I\Iount Janing was soon left behind, 

 and at noon on the same day the first jerani, or rapid, was 

 reached. Progress now became very slow, as jeravi followed 

 jerain in rapid succession ; at each of these the canoes had to 

 be unloaded and dragged over the rocks, whilst the stores 

 were carried along the shore or borne on the heads of the 

 natives, wdio were at times breast deep in the water. Many 

 of \h^jeranis are really small waterfalls over which the riv^er 

 rushes with considerable force. Several times the canoes were 

 torn from the hauling ropes of rotan, and swamped, and in 

 one or two cases stove in, I believe, so that before the close of 

 the first day of this sort of work, there was not a single pack- 

 age of stores that had not been under water at least two or 

 three times. We had now entered a hilly country and the 

 river became rockier and more winding every hour. 

 ■ The geology of this region appears to be very simple. 



A granite bed rock overlaid by a series of clays and clay 

 shales, traversed by many dykes of quartz felsite, and quartz 

 porphyry, with here and there irregularly intruded masses of 

 felsite, diorite, trachyte and other felspathic rocks. 



T\\^ jerams are in most cases formed by outcropping masses 

 of quartz felsite, some few, however, are of granite and granite 

 porphyry. Many of the hills are distinctly conical, notably 

 Gunong Berumbun and Bukit Tenegon which rise abruptly 

 from the Pahang bank. 



From Mount Janing onwards the country on either side of 

 the river, presents one mass of hilly uninhabited jungle. 



On the afternoon of the 23rd, we reached the highest point 

 navigable by small canoes. Hear the Indau is simply a broad 

 shallow stream heaped up with boulders of granite felsite and 

 diorite, we, therefore, abandoned the boats and continued the 

 journey on foot, cutting a path along the bank or more 

 frequently wading in the bed of the stream ; heavy loads and 

 torrents- of "rain made matters somewhat trying for the next
