In latitude 30 degrees 37 minutes, are three small rocky lumps, very remarkably placed; the middle one is in latitude 30 degrees 37 minutes 40 seconds: fourteen miles to the south of these are two others, the north-easternmost is in latitude 30 degrees 51 minutes 50 seconds, they are very conspicuously placed upon a ridge of bare white sand.

Hence the coast winds to the South-South-East for eighty miles as far as the entrance of Swan River.

The coast is low and slightly wooded, and lined with reefs, that in some places extend for two miles from the shore.

Off CAPE LESCHENAULT (in latitude 31 degrees 21 minutes) is a reef, lying six miles and a half from the shore; it appeared to be connected with the rocks that line the coast.
The following account of SWAN RIVER is taken from Captain De Freycinet's account of Baudin's voyage (page 175 et seq).
"The mouth of Swan River is in latitude 32 degrees 4 minutes 31 seconds, and longitude 113 degrees 26 minutes 28 seconds East of Paris, or (115 degrees 46 minutes 43 seconds East of Greenwich).

The channel is obstructed by a bar of rocks, which it is very difficult to pass over, and, indeed, impracticable if the wind blows from the sea.
