Finding good anchorage in tlie harbour of Ke-lung we 

 remained there for some weeks, or rather we made this place 

 a starting point for some interesting excursions, returning 

 to it again during the interval, and allowing thus some 

 opportunity for geological and natural history investigations. 



On this side of the island sandstone prevails, and the 

 whole environs of the town of Ke-lung are of that rock, 

 which extends from Masou peninsula, north of Ke-lung, to 

 Petou promontory on the south and east. The section of 

 the coast between these points exhibits inclined beds of red 

 sandstone with an average dip of 16° or 17° to the south- 

 east, the weatherworn outcrops producing an undulating 

 country. The hills at the back of the town of Ke-lung are 

 also of the same formation, and have a similar dip and 

 strike. The harbour of Ke-lung is a spacious excavation in 

 these sandstone strata, the navigable entrance being narrowed 

 by a low flat sandstone table ten feet above high-water, 

 called Bush Island, on the south side ; between which and the
