10 -A TRIP TO GUNONG BENOM. 
this limestone has recently been shown to reach to a depth of 
over 900 feet below the present surface. The height at which 
the old sedimentary rocks remain on the east side of the main 
range as compared with the west is very noticeable when cross- 
ing the range by the Pahang Trunk Road. Further I have 
walked along the foot of the range the whole way from Tramun 
southward to the Triang (a tributary of the Pahang which rises 
in Jelebu) and have not only seen no granite but have found the 
pebbles in the streams to be mostly of sedimentary rarely of 
igneous rocks. ‘The rocks over which I passed were all sedi- 
mentaries. The bed rock of the Bentong alluvial flat where the ~ 
mines are worked is uniformly not a bed of china clay as is 
usual on the western side of the Peninsula but a denuded sur- 
face of slates on edge. 
I was unable to ascertain the name of the hill on which the 
beacon is placed. It is certainly not Bukit Palas as I’ passed 
over Bukit Palas on my way to it. It may possibly be Kluane 
Terbang. At places bowever like Raub where no native seems 
to go into the more inaccessible jungle, local names are very 
uncertain. 
If another attempt is made to fix a station on Benom I 
would strongly advise that another route be chosen. At Raub 
labour is very expensive and natives with any idea of local to- 
pography are nonexistent. Sakais there are none. Personally 
if I were to try again I should begin by making enquiries as to 
routes up the Dong or by the Krau, a tributary of the Jelai on 
the other side of the ‘ massif.’ 
List of Plants Collected. 
Iilicium evenium, King. Also occurs in Malacca, Selangor and 
Perak. . 
Polygala venenosa, Juss. var. This is the same plant as that 
collected by Wray on Gunong Bubu (No. 3813) and 
distributed under this name by Kine and is probably the 
var gracilis of Miquel. It is very unlike the ordinary 
form of the Penang and Perak hills, having a long termi- 
nal spike of flowers and not short axillary ones.
