42 DUTCH BORNEO-EXPEDITION. 



{Tupaia) while fishing was entirely out of the question 

 and bat very few reptiles could be obtained. 



In order to get more suitable collecting grounds , Dr. 

 Hallier and I removed medio December to the southern 

 foot of Mount Kenepai, a mountain west of the Batang 

 Loepar Lakes and not very far distant from the frontier 

 of Sarawak. Until shortly after the New-Year I resided 

 in Roema Manoeal , a large native house, inhabited by 16 

 families of Kantoek Dyaks. The more elevated country 

 made a far more favorable collecting territory than the 

 inundated plain , and in spite of the heavy rains my col- 

 lections increased very rapidly. 



At the beginning of January 1894 Dr. Hallier returned 

 to Smitau , while I removed from Roema Manoeal higher 

 up to the south-western slope of the mountain. There, at 

 an altitude of 550 meter above the level of the sea , I 

 pitched my tent close to a lovely spring and had a hut 

 built for my people. The slope of the mountain was very 

 steep and entirely covered with high forest, in which 

 creepers and numerous large boulders of rocks made hunt- 

 ing a very tedious work, and many valuable objects, which 

 after much trouble we chanced to have a shot at, were 

 lost between the rocks or in an inaccessible ravine. I had 

 the greatest trouble in getting our mammal- and bird- 

 skins dry. Clear, sunny days were extremely rare, for, 

 whenever we had no heavy showers , the flanks of the 

 mountain were thickly covered with mist , and so moist 

 was the air that even the objects dried near or over the 

 fire, were wet again the next day. Very often we had 

 the pleasure of meeting with Orang-oetans which are not 

 at all rare on Mount Kenepai up to an altitude of 700 

 meter, and their nests were rather numerous even in the 

 immediate vicinity of our camp. 



Several times my hunting excursions led me to the top 

 of the mountain , a very steep , isolated cone which , on 

 clear days , offers a splendid view over the greater part of 

 the Kapoeas plain. It required a steady climb to reach the top,
