IN SUMATRA. 249 



few examples perhaps could exhibit this similarity more than 

 the one under notice ; its pollen moreover being less friable 

 than that in most species of its family, and singularly viscid. 



I could have spent many months investigating the natural 

 history of this district, but, time being short, I pressed on to 

 reach Muara Mengkulem, whence I hoped to be able to make 

 an expedition into the Djambi Lands. Using his great influ- 

 ence with its chiefs, the Pangeran of the Eawas might be able 

 to obtain entrance for a white man not a Hollander, of whose 

 entrance the Sultan was naturally extremely jealous and 

 afraid. From Surulangun the road kept by the north side of 

 the Eawas river, to the halfway village of Pulau Kida, near 

 which is the boundary between the diluvium of recent age 

 and the Palaeozoic strata, which, extending away north-west to 

 Limun, contains the auriferous rocks which have made that 

 country famous for the quality and colour of its gold. I passed 

 many people washing the earth of the high banks of the river ; 

 and at a spot some sixty feet above its present bed, opposite 

 where it is obstructed by a cataract a mile and a half in length, 

 I saw an ancient mine of the natives. Late in the afternoon 

 we reached Muara Mcngkulom.
