a very small portion of the decomposed surface, so that it cannot 

 as yet be said whether this is a dyke or a more extensive out- 

 pouring of trap. 



Lahat. 



Separated from the vaHey of Pappan by a low granite spur 

 from the main range is the valley of Lahat, a stream tin deposit 

 taken up by the Company, of which Mons. J. Errington de la Croix, 

 is the manager. It is as usual a stream tin deposit, but is not yet 

 uncovered sufficiently to enable one to pronounce upon its richness. 

 The drift appeared to be of moderate depth and mostly of fine 

 sand and clay, with a good deal of vegetable deposit. The drift 

 has been formed by the river Kinta which winds around this spur. 

 I could see no outci-op of any rock except granite, but the lime- 

 stone is all through the adjacent valley. 



Mons. de la Croix has cleared the timber from a portion of the 

 side of the valley. This has given him a beautiful site for his 

 residence and the houses of his assistants at a height of 170 feet 

 above the river. The view from this is very extensive. The 

 Kinta ranges appear of moderate height to the westward. To the 

 east were high ranges of mountains from 5000 to 8000 feet, 

 fronted by limestone cliffs and hills, some about 1200 feet in 

 elevation. These are thickly wooded, and all around the plains 

 was dense jungle. 



GOPING. 



This is an extensive valley of stream tin deposits about 10 

 miles from Lahat. The mines lie on the eastei'n side of the 

 Kinta and on the eastern side of the limestone range, in a valley 

 formed by spurs from the main range. It is said that the stream 

 tin has been nearly worked out. The mines are few in number 

 and apparently have been inefficiently worked. From the habit 

 the Chinese have of throwing the stripping or spoil heaps in all 

 directions, it is very probable that much ground is covered which 

 has never been worked at all. It seems to me very improbable 

 that such a large valley can have been completely tested, much 

 less exhausted.
