JOURNEY ACROSS THE MALAY PENINSULA. liz 
and said unkind things of the Orang Kaya Liris, who kept 
walking on the bank in an aimless way seemingly quite 
unable to meet such a demand on his energy and resources. [| 
of course said nothing, but Wan Att told me the Yam Tian 
had sent orders to all the Chiefs to assist me and treat me as 
they would himself. I had paid Tou Bikar for the very great 
help he had given us (without any orders from his Sultan) and 
I also sent-away Tou Kut happy with a present, for he is not 
well off, nor in the way of squeezing other people to do his 
work, but I only thanked the Orang Kaya for what he did and 
in any case I should have hesitated to offer him money. 
I was sorry not to meet here the Orang Kaya JELEI, to whom 
the Sultan had sent a letter telling him to meet us at Pénjum, 
but the Orang Kaya lives so far off he had not time to comply 
with the order, and I left 2 message for himin case he came after 
we had gone. The delay in getting our party finally settled 
into boats was so great that we did not leave Pénjum till 
10 a.m. 
Above Kuala Priok, Coz Wan Da met us with a present of 
rice, and we stopped at the Kuala, a beautiful place, for break- 
fast. Cur Wan Da’s father lives here. On the way down 
the river, we passed a gigantic waterwheel fixed in the river 
and used for irrigating the land on the bank. The wheel 
( undershot ) is forced slowly round by the current of the river. 
On its outer circumference are fixed at a certain angle lengths 
of bamboo closed at one end and open at the other and as the 
wheel revolves these bamboos in turn enter the river, mouth 
upwards, are filled with water, and, as they arrive at the highest 
point of their orbit, they, one after the other, discharge their 
load of water into a trough which conveys it by gravitation to 
the required point in the field. I have not before seen in the 
Malay States so large or well-constructed an irrigating wheel, 
but I believe they have been and still may be used in Ulu 
Muar. 
Left Kuala Priok at 1.30 p.m. and continuing our journey 
reached Kuala Lipis (where this river falls into the Jélei) at 
1.50 p.m. Here CHE Wan Da left us to return to his home ; 
he has been very useful and shewn a great desire to be friendly 
and helpful. The combined rivers—the Lipis and Jélei—imme- 
diately after their junction, are about sixty yards wide. The
