Eeferring to a letter, by Col. Greenwood, on this subject (see p. 134), 

 the writer, while admitting Col. Greenwood's " hard-gorge-and-soft- 

 valley '■ theory generally, does not see how it accounts for the forma- 

 tion of great thicknesses of alluvial beds in the gorge as well as in 

 the wide valleys. F. D.

 Describes a journey through Siak, on the east coast of Sumatra. 

 Geological observations are recorded, and a list of borings for tin- 

 ore is given. The map, on a scale of 450^000^ shows the course of the 

 rivers Siak and Kampar, and is partly coloured geologically. F. W. II.

The main hUl of the range is in E. long. 75° 45' and N. lat. 15° 13' ; 

 the rock is of the great gneiss formation of S. India, of granitoid 

 gneiss and various sorts of schists, much disturbed. Quartz-reefs 

 occur in all these rocks ; but from one only did the author succeed in 

 obtaining gold. This reef was 5 feet thick on the average, and half a 

 mile long, direction N. by "VV., dip easterly, 40° to 50°, of ordinary 

 dirty-wliite quartz, in parts ferruginous. It seems to contain but a 

 small proportion of gold. Even it" tlio reefs were moderately auri- 

 ferous, miners would have many difficulties; no fuel is near, and 

 water is generally scarce. Alluvial gold is washed from the stream- 

 deposits derived from the hill-tract ; the process of washing practised 

 by the natives is described, and their plan of selecting wash-dirt. 

 Very small quantities of gold are obtained. The paper concludes with
