the rattan thickets were more impenetrable than I have 
seen them on any other mountain in Sumatra. At 1900 M. 
a camp was made near the Air Sarasah, a small mountain 
stream in a ravine with perpendicular walls. The forest 
thins out considerably at this altitude, the trees being 
covered with moss. The undergrowth consists for a great 
part of the Gingerwort Alpinia. About 200 M. higher up 
the forest disappears abruptly, to be replaced by dwarfed 
trees and bushes standing further apart, and the ground 
is covered with a tangled mass of ferns, creepers and 
grasses. Near the top a plateau occurs (2780 M.), this 
being the old crater, filled up except for a number of small 
pits with perpendicular sides. 
The plateau is clothed with a carpet of lichens, and 
a scanty growth of grass, Vaccinium, Rhododendron, and 
a number of other tropical alpine plants. 
Only three species of birds were found at this altitude. 
At my camp on the plateau I noted temperatures of 6° C 
above zero at night. The rainfall on the lower slopes of 
the mountain is very heavy and from 6000-7000 mm. 
a year. 
Kamang, Agam, Padang Highlands, 880 M. 
The valley of Kamang is covered by ricefields and 
numerous villages, with their usual gardens. The hills 
enclosing the valley are chiefly of limestone covered with 
secondary forest. The country is partly swampy and in 
some places large numbers of waterfowl can be found. 
Kodjai, foot of Mount Talamau (Mount Ophir), Ophir 
Districts, 280 M. 
This little hamlet is surrounded by ricefields and 
plantations. 
Korinchi Peak, Korinchi. 
The Peak (3806 M.) is on the frontier between the 
Padang Highlands and Korinchi. I ascended it from the 
Korinchi side, coming from Sungai Kumbang. Very little 
collecting was done by me from 1500-2200 M. 
I only obtained some specimens at a camp called by 
the natives Sungai Kring Ilir (1500 M.), where the Sungai 
Kring reaches the border of the Danau Bento, covered with 
old forest. 
At 2220 M. I found an old camp of Messrs. Robinson 
and Kloss, who had been here the year before. The place 
was called by the natives Sungai Kring Ulu. 
The trees at this altitude were low, with an under- 
growth of Vaccinium bushes and other alpine plants. I 
reached the top of the Peak but did not collect above 2200 M.
