secured a new lamp chimney and then continued our hunt for other ani- 
mals. After several more experiences with crocodiles, my natives came 
to me and said that if I was going to continue to shoot crocodiles from a 
small canoe they wanted to leave my service, for they said that croco- 
diles had often overturned canoes and then eaten the occupants. When 
informed that I would be careful and that I did not intend to shoot any 
more crocodiles at such close range they were satisfied for the time 
being. 
Some of the natives were very enthusiastic about hunting at night 
and were always delighted when they learned that I was going; others 
seemed to think that it was a useless sort of thing to do as the animals 
usually obtained were of no use to them for food, though the Dyaks as a 
rule would eat almost any kind of meat. On one occasion I found a 
group of proboscis monkeys {Nasalis larvatus) sleeping in the trees that 
overhung the river, and by getting nearly under them and playing the 
light on them from below for a few moments and then turning it aside 
for a few seconds so confused the monkeys that when we made a noise 
below by shouting and clapping the paddles on the water they jumped 
about from branch to branch. Two fell from their high perches. One 
caught on some lower branches and the other came down into the water 
and, as it was a large one was shot as it climbed out on the branches 
protruding from the bank. 
Early in 1914 I made a trip up the Mahakkam Eiver. It was pos- 
sible to have my houseboat-like prahu of a sea-going type towed up the 
river as far as Long Iram by a small steamer. At Long Iram the Dutch 
Official, Captain Muller, very generously helped me to procure Dyaks 
as paddlers and loaned me a long canoe in which to travel to a Dyak 
village known as Long Hurei. At this place, where I found Bahau 
Dyaks, I sent the long canoe back to Long Iram and secured from the 
Bahau three smaller canoes and some of their people to take me up 
Long Merah, a river confluent with the Mahakkam above Long Hurei 
and coming in from the northward. After two days of paddling against 
the current and poling up rapids, the Bahau brought me to a temporary 
dwelling place of some Punans or nomadic Dyaks. I wished to camp 
among the Punans for a time, so the morning after our arrival my Bahau 
friends departed and I told them that when I wanted them to return 
for me I would send one of the Punans down to bring them word. 
For a few days I camped with the Punans and then moved about 
half a mile down stream and made camp on the opposite bank of the 
river. While encamped here in the absolutely virgin forest where the
