 Ambong, from the depth of which bay it appeared at 

 dawn to rise perpendicularly, although at least twenty- 

 seven miles inland. The position of the highest pinnacle 

 was computed to be in Latitude 6 8' 24" N., and Lon- 

 gitude 116 33' E., the mean height resulting from the 

 three best stations giving 13,698 feet above the mean

 boats were absent, and the gig alone entered. From the 

 mouth of the Sulaman to the river Kawalan is about two 

 miles. Here we found an extensive village, and were 

 visited by some of the people, who brought us presents 

 of fish, and appeared disposed to be on friendly terms. 

 They explained that they belonged to the boats chased in 

 the morning, which contained nothing but cargoes of fish 

 and rice for Brune. The river is navigable, and not troubled
