AN EXPEDITION TO MOUNT BATU LAWI. ti 
thrown across and interlacing foliage; through this filters the strong 
tropical sun, lighting up a glistening patch here and there in the 
winding stream beneath. Along this stream, as we enter, an 
occasional crocodile (three I counted) splashes clumsily into the 
water from off the muddy bank where he has been lying in wait 
for a chance meal; a little further on a “ biawak ” (Monitor lizard) 
walks stealthily up the bank hoping to escape notice. The stream 
becomes too small for our boat and we get out and walk over the 
rough stony bed; just at the bend ahead of us a pheasant (an Argus 
by the length of its tail) flutters across the stream and disappears 
up the opposite bank; I am too occupied with slippery boulders to 
get my gun up in time. Overhead we caught a glimpse of two or 
three “tajak” (Solid-casqued Hornbill, Rhinoplax vigil), usually 
out of range and jeering at us with their curious mocking cries. 
The lovely velvety black and green brookeanus ( 6 ) butterfly dances 
by at a good pace and soon after we see another beautiful green 
Papilio, known locally as the “ Sarawak Beauty” (Papilio arjuna 
carnatus); a frail black-spotted flestia floats lazily by out of 
reach of the net, and then ensues an exciting chase after the rich 
green dragonfly Neurobasis chinensis, which, in Sarawak, is only 
found in the upper reaches of rivers. On returning to Belulok’s 
house we find the same species of tiger-beetle (Cicindela funerea) 
swarming on the sand-bank at the water’s edge, which I found in 
the same. place last year; curiously enough I never could find it on 
any other similar locality above or below this spot on the Limbang 
River, nor indeed anywhere else in Sarawak. Last year another 
Cicindela (C. crespignyi) was found abundantly on the same spot, 
and in many places most of the way up the river, but on this 
occasion it was entirely absent on that sand-bank and only sparsely 
taken at different places further up. 
Heavy rain for the rest of that day, but apparently only local 
as 1t did not prevent us continuing next morning. 
May 10th: (Temp. at 9 a.m. 82°). Having arranged with 
Tama Belulok to collect in some of his men and to follow with 
Gesang, the Dayak, next day or if possible that afternoon, we leave 
his house in the morning and soon come to our first rapids, in this 
case “ wood-rapids,” 7.e. rapids formed by a mass of timber stuck 
in the bed of the river and sufficient to partially choke the stream. 
Going is rather slow against the strong stream, and it takes us till 
2 p.m. to arrive at the kuala Madalam. Our friends of yesterday 
meet us here and we are taken up into Tama Seluling’s house to 
spend the night. ‘Tama Seluling himself is a very short ugly little 
Tabun, who seemed to spend most of his time nursing his little son 
or else out with a “jala” (casting net) after fish. ‘The first’ time 
_I went there (last year), he insisted on giving up his bed: for my 
use, and I did’nt like to refuse to use it, although the nights spent 
thereon were not all pleasure! The river divides here, one branch 
really the main Limbang River, goes off to the South-East, the other 
is called the Madalam River and rises in Mount Molu. .On my
