A. strip that extends towards Cape Van Diemen. On either 
Sect. Ill, point, near Karslake Island, is a bay, and at the 
N. Coast, bottom of each there is an opening in the land, like those of 
Brenton and Lethbridge Bays. 
The western trend of CAPE VAN DIEMEN is in latitude 
11° 8' 15", and longitude 130° 20' 30". The coast to the 
south-east of the cape is formed by a range of cliffs, extend- 
ing uninterruptedly for seven miles, of a most remarkable 
white appearance, whiter even than the usual colour of the 
pipe-clay cliffs to the eastward. Cape Van Diemen is a low 
sandy point, with a shoal spit projecting from it for four 
miles, within half a mile of the extremity of which we had 
no bottom with ten fathoms : from this a very considerable 
shoal (Mermaid’s Shoal) extends to the westward and 
south-westward for seventeen miles ; and, curving round to 
Piper’s Head, forms the northern limit of the entrance to 
Apsley Strait: its western edge is rather steep ; we coasted 
along it, and had overfalls between ten and four fathoms 
near its edge. It is not only possible, but very likely, that 
there are channels through it, but the most direct chan- 
nel is round its south side, across the bar, on which there 
is (at low water) five fathoms. To sail into Apsley Strait 
by this channel, if coming from the westward, steer in on 
the parallel of 11° 15', until the northern part of Bathurst 
Island is seen : when the western trend of the island bears 
South, you will be abreast of the west extremity of the shoal 
off Cape Van Diemen. Steering on, you will see Piper’s 
Head, a cliffy point, forming the north entrance to the 
strait, which must be kept upon the bearing of E.b.N., until 
the low, sandy, south point of the strait’s entrance * is in a 
line with the summit of Luxmoore Head, a remarkable flat-
