AN EXPEDITION TO MOUNT BATU LAWI. 31 
able spot is on the wooden platform outside the end of the house ; 
it is quite nice sitting out there in the evening with a glorious view: 
all round, but too hot to stay there in the heat of the day. A scaly 
- ant-eater (Manis javanica) is brought in having been captured by 
the dogs of the house. 
Owing to the thickness of the mist they will not be able to 
dry any paddy to-day for us to take, so we shall have to wait here 
to-morrow before starting off again. ‘There appears to be no chance 
of getting any more coolies, so all we can do is to carry enough | 
- food for ten days, which should enable us to do the journey to Batu 
Lawi and back and no more; but | hope we can shoot something 
- and find a little jungle produce to enable us to stay there a few 
- days; however the chief thing is to get there first. 
Went out in the morning down the hill on the north side of 
the house and heard the waters of the Madihit below us. It 
appears to run in a south-easterly direction (1.e., following it from > 
the mouth it runs south as far as the kuala Aripenou and thence 
south-east past this hill). I cannot make out which is Mt. Obong 
and which is Mt. Molu of the high peaks in the range to the west 
of us; this has been a source of argument the whole way up, some 
saying one thing and others flatly contradicting; the only thing. 
that is clear is that the whole range is the Molu Range; the highest 
is a double peak and to the north of that (in the same range) are 
four other peaks whose bearings I read as 281°6, 290°4, 287°5 
and 300:2 respectively. The first they tell me is the source of the 
Seridan river, which runs into the Mago and thence into the Tutau 
and Baram. 
May 21st: (Temp. 76°). A nice fine morning and every 
prospect of drying the paddy and getting off to-morrow. After, 
a bathe under a bamboo pipe stuck into the hill side,—the only 
water to be obtained here, we go off collecting in different direc- 
tions. Catch some interesting insects, among them an interesting 
female Chaleosid moth, which mimics the common Pierine butter-, 
fly Terias hecabe; the male is entirely different in colouring and 
pattern.* The beautiful Papilio brookeanus appears to be common. 
The collectors bring in a large male “ brok ” (Macacus nemestrinus) | 
and a fine bushy-tailed squirrel. (Rhithrosciurus macrotis). 
T amused the company and myself by measuring the right-hand 
ee to little finger stretch of 25 men (adults). They were as 
ollows :— 
Sea-Dayaks. Tabuns. Kalabits. Muruts.
