Having left Sandalwood Island, we had light 

 winds for the two following days, but about noon of 

 the 1 1-th, we entered the Strait of Alass. As we 

 approached it we could see the high land of 

 Sumbawa on our right, almost entirely enveloped 

 in clouds, while on our left was the lower and nearlv

 into ridges of about four or five hundred feet above 

 the sea. The cliffs are white at the base, capped

 the stratification was not perceptible, but its upper 

 surface was level and horizontal, and the brown 

 rock upon it was regularly and horizontally strati-

 crag resting upon chalk. The opposite coast of 

 Sumbawa rose in steep and broken precipices to a 

 height of at least 2,000 feet ; still loftier hills in the 

 interior, peering dimly out here and there through

 abrupt ravines traversed these rugged-looking hills; 

 but even here all the rocks appeared to be regularly 

 stratified, and the sides of the ravines shewed a con-

 to bottom, inclined generally at no great angle,
